Abstract

PURPOSE:To rationally and smoothly execute input by a key by eliminating the value of the largest digit when data inputted successively to an input part becomes the data to designate an area other than a prescribed range. CONSTITUTION:A key-inputted output signal from a remote controller 4 is received by a remote control code demodulating part 8 through an infrared light receiving part 6 in a still picture reproducing device 2, and is transmitted to a system control part 10. The system control part 10 drives a disk drive unit 12 so that ID information such as a truck number, etc., to be recorded on a disk 18 is demodulated by an ID demodulating part 25, and after that, it displays the truck number, etc., on a display part 40. Here, if the system control part 10 designates the truck number not existing at the time of key input, it changes the inputted truck number into another truck number by eliminating the largest digit of the inputted truck number while it makes this designation impropriety. Therefore, operability at the time of input is improved, and erroneous input can be easily corrected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data input device suitable for use in a reproducing device such as a still image reproducing device.

[0002]

2. Description of the Related Art Still video cameras (hereinafter referred to as SV cameras) have been proposed for electrically recording image information. Information recorded on a video floppy disk (hereinafter referred to as a disk) by this SV camera is output by a dedicated reproducing device. In this type of reproducing apparatus, when it is desired to specify a reproduction area (track) for reproduction, a number (hereinafter referred to as a track number) for specifying a certain track is given, and the track number is digitized by one digit. It is a general practice to use an input device in which a key (access key) for reproducing a specified track is specified by inputting each of them.

In such an input device, when a nonexistent track number is input, it is possible to specify a nonexistent track, but when the access key is operated, the upper limit or the lower limit of the track that can actually be reproduced is reached. Some are played back, some are rejected when a nonexistent track number is input, and so on.

[0004]

In the above-mentioned method, although the area which is not permitted can be designated, the image information recorded on the track different from the intention of the user is reproduced or used. When a person makes an erroneous input, the operability is inconvenient and inconvenient because, for example, after performing a reproducing operation on the erroneously input track, it is necessary to specify the track again.

In view of the above problems, it is an object of the present invention to provide a data input device capable of performing input by keys reasonably and smoothly.

[0006]

SUMMARY OF THE INVENTION In order to solve the conventional problems and achieve the above object, the present invention provides an input section capable of sequentially inputting one digit for designating a predetermined area, and an input section. An area determination unit that determines the specified area, and a control unit that rejects an input that specifies an area other than the predetermined range,
The control unit, as a result of being sequentially input by the input unit,
When it comes to specify an area other than the specified range,
It is configured to erase the value of the largest digit.

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing an outline of a still image reproducing apparatus to which the present invention is applied.

The remote control transmitter 4 is provided with a ten-key pad, an access key, etc., and enables various commands to the still picture reproducing apparatus 2. The output signal from the remote control transmitter 4 is received by the remote control code demodulating unit 8 via the infrared light receiving unit 6 in the still image reproducing apparatus 2. The data code demodulated by the remote control code demodulation unit 8 is transmitted to the system control unit 10 that controls the entire system.

A disk drive unit (hereinafter referred to as a drive unit) 12 has a head 16 fixed to a carriage (not shown) movably provided by a step motor 14 and a disk 18 when the disk 18 is mounted in the drive unit 12. A spindle motor 20 for rotating is provided.

The signal reproduced by the head 16 is demodulated by the FM demodulator 24 via the preamplifier 22. The demodulated signal is converted into a video signal by the reproduction signal processing unit 28. On the other hand, the ID information such as the track number, the date, the hour, the minute, the second, etc. recorded on the disc 18 together with the image information is demodulated by the ID demodulation unit 25 and then the character generator 30 generates the characters. Is superposed on the image signal and output as a video signal from the output terminal 38 via the encoder 32 and the buffer 34. Also, the track number and the like are displayed on the display unit 40.

Next, the processing operation by the system control unit 10 will be described. Here, for simplification of description, a case will be described in which the key input by the remote control transmitter 4 is limited to the numeric keys “0” to “9” and the access key, and direct access is performed. FIG. 2 is a flowchart showing a processing procedure when performing direct access reproduction by the remote control communication device 4. In this flowchart, the variable I represents the input value of the key, and the value representing the input of the access key and the numerical value for designating the track number are “0” to
"9" is input. The variable S is a numerical value indicating the currently designated track number.

STEP 1: Input 0 to S.

STEP 2: When the key input of the remote control transmitter 4 is made, the output signal of the remote control transmitter 4 is demodulated by the remote control code demodulation section 8 and the system control section 1
0, and the data processing unit (not shown) of the system control unit 10 replaces the variable I by the input.

STEP 3: The replaced I is "0"-
It is determined whether it exists in "9". If it exists, move to the next step. If it does not exist, the process proceeds to STEP8.

STEP 4: Replace the variable S with 10.multidot.S + I.

STEP5: It is determined whether S> 50 is satisfied. If it is satisfied, move to the next step. If not satisfied, the process proceeds to STEP 7.

STEP6: Erase the most significant digit of S and delete S
Return to TEP5.

STEP 7: The track number stored in S is displayed on the display section 40 and the process returns to STEP 2.

STEP 8: Since the access key has been pressed, the disc unit 1 should reproduce the designated track.
Drive 2

An example of operation according to the above-mentioned flow will be described based on the display example shown in FIG. As shown in FIG. 3A, starting from the state where “7” is displayed on the display unit 40 and inputting “1”, S = 1 (<50). As shown, "1" is displayed. When “2” is continuously input, S = 12, which is “12” as shown in FIG. If you enter "3" continuously, S
= 123 and S> 50, the most significant digit is deleted and S = 23, and "23" is displayed as shown in FIG. 3 (d). If "6" is continuously input, S = 236 and S> 50. Therefore, the most significant digit is erased and S = 36, and "36" is displayed as shown in FIG. 3 (e). When "1" is continuously input, S = 361 and S> 50. Therefore, the most significant digit is deleted and S = 61. But,
Since S> 50 is still satisfied, further erasing the most significant digit results in S = 1, and “1” is displayed as shown in FIG. 3 (f). After that, when the access key is input, the track with the track number "1" is reproduced.

As described above, according to the present embodiment, when a non-existing track number is specified at the time of key input, it is possible to convert the track number into another track number within the allowable range according to the input track number, even though the track number cannot be specified. With this configuration, operability at the time of input is improved, and erroneous input can be easily corrected.

Next, an embodiment in which the remote control transmitter of the SV camera having the reproducing function is the above-mentioned data input device will be described with reference to FIG. In this case, when the operation switch provided on the camera body is in the "play" position, the CPU in the camera receives the remote control signal while reading the state of the switch related to playback such as the forward / reverse switch of the track on the camera side. Therefore, when the switch on the camera side is pressed, it may not be possible to operate the remote controller. In the present embodiment, the configuration is made so that such a case does not occur.
