Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a video controller, and more particularly to a video controller having a jog function of sending a reproduced image before and after a predetermined kotsu.

[0002]

[Prior Art]

 In recent years, the technology of playing back images recorded by a recorder on a medium such as a video tape or video disc by a player for each medium has been remarkably developed, and the device is downsized and the resolution of recorded images is improved. Various proposals have been made for the purpose of improving the recording time, making the image control multifunctional and improving its operability.

Among the above-mentioned purposes, as multi-functionalization of image control, a playback image of a video tape or a video disk is made to stand still and viewed one by one, or a playback image is made to stand still for the purpose of editing the video tape. From this state, a jog function has been proposed in which one frame, or a plurality of chips, and frame feed / come back are proposed, and a video controller provided with this function is widely used.

On the other hand, there is a remote control device for operating the controller body from a remote position in order to improve the operability of the video controller. This is because, for example, in the case of a video tape controller, signals such as infrared rays are transmitted and received between the remote control device and the controller body, and operations such as start / stop of playback and fast forward / rewind are performed by the remote control. It can be performed by the device. When the above-mentioned jog function is provided in this remote control device, conventionally, a handle (jog shuttle) is provided in the main body of the controller or the remote control device, and by rotating this handle with the image stationary, the rotation direction and rotation can be changed. The top feed / top return was performed according to the amount.

However, since the handle described above is large enough to be gripped by the user, and the handle projects from the operation surface of the remote operation device, when the handle is provided in the remote operation device, only the jog function is provided. For this reason, not only the remote control device became significantly large, but also the number of parts tended to increase due to the addition of the handle and its accompanying parts. Also, for example, if you want to feed the frame quickly (returning the frame), the handle is rotated at high speed, but the operation takes time, the operability deteriorates, and the parts are worn out more heavily. Or there was a concern that the life of the remote control device would be shortened.

Therefore, a plurality of touch switches that are operated by touching or pressing and that are continuously operated so as to circulate are used as jog switches to rotate the handle. Similarly, by tracing the touch switch in a circular shape, the jog function can be used with a simple structure.

In this case, it is desirable to reduce the number of switches in terms of structure, but it is desirable in terms of function to increase the number of switches to increase the accuracy of division of the top, and satisfy these contradictory requirements. Things are required.

[0008]

[Problems to be solved by the device]

 The present invention has been made in view of the above-mentioned problems of the prior art, and its main purpose is to increase the accuracy of division of the top in the jog function without increasing the size and the number of parts. It is to provide a video controller that can easily do so.

[0009]

[Means for Solving the Problems]

 According to the present invention, the above-mentioned object is capable of reproducing continuous video information recorded on a medium, and is provided with a switch means that can be continuously operated by a user and a reproduced image is stationary. Is a video controller having a jog function of frame-feeding / frame-backing the reproduced image displayed when the switch means is first operated by continuously operating the switch means. The means comprises a plurality of touch switches that can be operated by being touched or pressed by the user and that are arranged in an annular shape, and that each touch switch is operated continuously while the reproduced image is stationary. Causes the touch switch operated first to correspond to one frame of the currently displayed replay image, and the replay image corresponding to the touch switch operated next. A video controller, which feeds / reverses the frame and simultaneously feeds / reverses the reproduced image to a frame in the middle of the frame corresponding to each switch when a plurality of touch switches are operated simultaneously. It is achieved by providing.

【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a video tape recorder (hereinafter referred to as VTR) as a video controller and a remote control device (hereinafter referred to as remote controller) as a video controller showing a first embodiment to which the present invention is applied. Is. The VTR main body 1 outputs the video and audio information recorded on a video tape (not shown) received in the main body to the monitor 2 and reproduced on the monitor 2. Further, this VTR main body 1 has a jog function of keeping the reproduced image still and moving from this state to one frame or a plurality of chips, frame feed / come back, and has a built-in control circuit 5 as its control means. There is. In addition, the VTR main body 1 is provided with a receiving circuit 3 which receives a signal from the remote controller 4 and can be remotely operated including the jog function.

The remote controller 4 has a substantially box shape, and one surface thereof is an operation surface. On this operation surface, there are provided a display section 6 for displaying operation contents and an operation switch section 7 arranged at a lower part of the display section 6 and having 4 rows × 8 stages, that is, 32 switches. ing. Each switch of the operation switch section 7 is a so-called touch switch that recognizes that the user has operated only by touching it, and has functions such as play, stop, pause, fast forward, rewind, and various reservations. is doing.

Here, the upper right switch SW32 is a function selection switch, and each time the switch SW32 is operated, the function set in each switch SW1 to SW31 is switched. For example, among the three rows × three stages of switches SW1 to SW9 on the lower left side of the operation switch unit 7 in FIG. 1, eight annular switches SW1 to SW8 surrounding the central switch SW9 are normally reserved for recording. Although it has general functions such as the above, by operating the switch SW32, it becomes a jog switch for performing the above-mentioned frame feed / come back for the jog function. That is, an image displayed on the monitor 2 is stopped by operating a certain switch of the operation switch unit 7, the switch SW32 is operated, and the switches SW1 to SW8 are used as jog switches, and these switches are shown in phantom lines. By tracing in the clockwise direction or the counterclockwise direction in this manner, the reproduced still image is frame-feeded / frame-backed by a predetermined number of frames.

FIG. 2 is a block diagram showing a schematic circuit configuration of the remote controller 4. A microcomputer 9 for signal control is provided in the remote controller 4. A display circuit 10 connected to the display unit 6 and an output circuit 11 connected to an LED 12 for transmitting an infrared signal to the VTR main body 1 are connected to the microcomputer 9. Further, eight output lines O1 to O8 and four input lines I1 to I4 are provided in order to detect the switch operation of the switches SW1 to SW32 of the operation switch section 7 from the microcomputer 9, and these are provided in a matrix. The switches SW1 to SW32 are provided at the intersections of 32 while being arranged like a circle.

The output lines O1 to O8 and the input lines I1 to I4 are connected only via the switches SW1 to SW32. That is, as shown enlarged in FIG. 3, for example, the output line O1 and the input line I1 are connected only when the switch SW1 is operated and turned on. Therefore, a signal is repeatedly output from each of the output lines O1 to O8 in order, and when the signal is input to any of the input lines I1 to I4, the operated switch is specified from the output line and the input line at that time. , A signal corresponding to the switch is transmitted from the LED 12 via the output circuit 11. Here, for example, when the switches SW1, SW2, and SW9 are turned on at the same time in FIG. 3, it may be indistinguishable from the case where the switch SW10 is turned on. Therefore, it is desirable that switches that will malfunction if turned on at the same time are on the same output line or the same input line. Since all the switches SW1 to SW8 used as the above-mentioned jog switches are provided on the output line O1, that is, on the same line, there is no such concern.

Next, an operation procedure of the main part of the remote controller 4 in the present embodiment will be described with reference to the flow chart of FIG.

First, after performing a key scan on all the switches SW1 to SW32 in step 1 and step 2, the process proceeds to step 3 to determine whether the switch SW32 is turned on and whether any of the switches SW1 to SW8 is turned on. That is, it is determined whether or not the jog switch is turned on. If the jog switch is not turned on, the process proceeds to step 4. If the normal operation switch is turned on, the signal corresponding to the switch is transmitted from the LED 12 Return to step 1.

If the jog switch is turned on in step 3, the process proceeds to step 5, the jog switch turned on is stored, the timer t is started in step 6, and the process proceeds to step 7. Then, the key scan is performed until one of the switches is turned on in steps 7 and 8, and when it is turned on, it is determined in step 9 whether or not the switch is a jog switch (SW1 to SW8). If not, the process proceeds to step 4, the signal corresponding to the normal operation switch is transmitted from the LED 12, and the process returns to step 1.

If the turned-on switch is a jog switch in step 9, the process proceeds to step 10, and it is determined whether the turned-on jog switch is the same as the previously turned-on jog switch. Return, if not the same, proceed to step 11. Then, in step 11, whether the jog switch turned on this time is the top feed direction (clockwise in FIG. 1) or the top return direction (counterclockwise in FIG. 1) with respect to the previously turned on jog switch. If it is in the top feed direction, in step 12, if it is in the top return direction, in step 13 it is determined whether or not 50 mS has elapsed since the timer t was started.

If the timer t has passed 50 mS in step 12, the process proceeds to step 14, and the LED 12 transmits a signal for moving the still image displayed on the monitor 2 by two. If the timer t has not passed 50 mS in step 12, that is, if the jog switch is operated quickly and continuously, the process proceeds to step 15 and the still image displayed on the monitor 2 is fed one by one. A signal for causing the LED 12 to be transmitted. Similarly, in step 13, if the timer t has passed 50 mS, the process proceeds to step 16 to move the still image back by 2 frames. If the timer t has not passed 50 mS, the process proceeds to step 17 to read the still image. Bring back only 4 pieces. Then, after performing the processing of any of steps 14 to 17, the process returns to step 5.

Here, in this embodiment, if each of the jog switches (SW1 to SW8) is sequentially turned on at intervals longer than 50 mS, it is possible to trace 16 turns to advance or return by 16 frames. .. That is, if the jog switch that was turned on last time and the jog switch that was turned on this time are adjacent to each other, 2 frames will be sent, and if one is skipped and turned on, 4 frames will be sent, and the frame will be fed / come back. There is. Therefore, for example, if the adjacent jog switches are turned on in sequence at intervals longer than 50 mS, 2 frames will be turned on, and if they are turned on at intervals shorter than 50 mS, 4 frames will be fed. If you turn on at intervals longer than 50 mS in order, it will be 4 frames, and if you turn on at intervals shorter than 50 mS, it will be 8 frames, frame feed or frame return.

In this embodiment, it is determined whether or not the interval at which the jog switch is continuously turned on is longer than 50 mS, and the amount of frame feed / come back per switch operation is set to 2 frames or 4 frames. Although it was decided, if the interval at which the jog switch is turned on is shorter than the predetermined short interval such as 30 mS, set the top feed / top return amount per switch operation to 5 or 6 tops. Is also good.

On the other hand, when a plurality of jog switches are turned on at the same time, it is determined that an intermediate switch between both switches is turned on. Therefore, as shown in FIG. 5 for example, when the switch SW1 is first turned on (portion a), and then the switches SW1 and SW2 are simultaneously turned on (portion b), one frame by one frame is fed. Then, if only the switch SW2 is turned on next, one more frame is advanced. Further, when the switches SW1, SW2, and SW3 are turned on at the same time as shown in part c of FIG. 5, it is determined that it is the same as the state where only the intermediate switch SW2 is turned on. As a result, the number of parts can be reduced and the size of the device can be reduced because the frame feed / come back can be performed with double the precision of the number of switches.

FIG. 6 is a view similar to the main part of FIG. 1 showing a second embodiment to which the present invention is applied. The same parts as those of the first embodiment are designated by the same reference numerals, and Detailed description is omitted.

In this embodiment, among the switches SW1 to SW40 in the operation switch section 17 of the remote controller 14, the switches SW1 to SW8 at the center of the lower part are arranged in a circle, and the upper right corner is provided as in the first embodiment. It operates as a jog switch by operating the switch SW40. Therefore, as compared with the first embodiment, the operability when operating the switches SW1 to SW8 as the jog switches is improved.

Here, also in the present embodiment, when a plurality of jog switches are turned on at the same time, it is determined that the middle switch between the two switches is turned on. Therefore, for example, as well shown in FIG. 7, when the switch SW1 is first turned on (portion a), and subsequently the switches SW1 and SW2 are simultaneously turned on (portion b), one frame and one frame are fed. Then, if only the switch SW2 is turned on next time, one more frame is advanced. Further, when the switches SW8, SW1 and SW2 are turned on at the same time as shown in part c of FIG. 7, it is determined that it is the same as when only the intermediate switch SW1 is turned on. Therefore, in the present embodiment, the frame feed / come back can be performed with an accuracy of twice the number of switches, so that the number of parts can be reduced and the apparatus can be downsized.

FIG. 8 is a view similar to FIG. 6 showing a third embodiment to which the present invention is applied. In this embodiment, a touch panel section 25 having a liquid crystal screen is provided on one surface of the remote controller 24. The touch panel section 25 is composed of an upper message display section 26 and a lower switch section 27 and can variably display desired contents on its entire surface. Further, the switch section 27 is adapted to recognize a switch operation by touching each switch area. Also in this embodiment, as in the second embodiment, SW1 to SW12 are circumferentially arranged to facilitate the operation when using the jog function. Also, in this embodiment, as in the above embodiments, the switch areas SW1 to SW31 are switched each time the switch area SW32 is operated. At the same time, the message in each switch area is changed. The display of the section 26 is also switched, and the operability is improved. The other structure is the same as that of the second embodiment.

In each of the above embodiments, the jog switch provided on the remote controller side has been described, but it goes without saying that a similar jog switch may be provided on the VTR main body side.

[Effect of the device]

 As is clear from the above description, according to the video controller of the present invention, the user can continuously operate, and the video controller is provided with the switch means composed of a plurality of touch switches arranged in an annular shape and the reproduced image is stopped. By continuously operating the switch means in this state, the first operated touch switch is made to correspond to the currently displayed reproduced image in order to advance / reverse the image, and then the next operated touch switch. Depending on the number of switches, it is possible to feed / return the top and bottom, and when multiple touch switches are operated at the same time, it is possible to easily feed / return the top / bottom with a small number of switches by using the top / bottom feed to the middle of the tops corresponding to each switch. Since the jog function with high division accuracy can be used, it is possible to prevent the device from becoming large and the number of parts from increasing. . In particular, when the touch switch is provided on the remote control device side, the effect becomes more remarkable.
