Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an imaging device for searching and displaying recorded images, and particularly to an endoscopic imaging device used for endoscopic diagnosis.

[Prior art] With the advent of electronic endoscopes, it is now possible to record endoscopic images on a recording device, search the recorded images as needed,
An endoscopic image device that displays images has been developed. According to this image device, the image recording/reproducing section and the monitor are directly connected, and an image is searched by keying in a search code, and a desired image is displayed on the monitor.

[Problems to be Solved by the Invention] According to conventional image devices, the image recording and reproducing section and the monitor are directly connected, so before specifying a desired image, that is, before image search, the image is reproduced from the image memory. Unnecessary images will be displayed.
Also, when a search is started, the search code information (binary signal) played from the search code rack is input to the monitor as a video signal, so when this binary signal is displayed on the monitor, a black and white signal is displayed on the screen. Flickering occurs.

[Means for Solving the Problems] According to the present invention, a first image signal output section outputs an image signal representing a transendoscopic image, a search section searches for an image in response to search information, and a predetermined a second image signal output section for outputting an image signal representing an image; a monitor for displaying the image; and a second image output section for displaying a predetermined image of the second image output section on the monitor in response to the start of playback. An endoscopic image device is provided, which includes an image switching circuit that switches to an image switching circuit.

[Function] In addition to the image output device for transendoscopic images, an image output section that outputs a fixed pattern of images is provided, and the fixed pattern is displayed before searching for the desired image.
Misreading the displayed image on the monitor screen and flickering of the screen can be avoided.

[Embodiment] According to the image device shown in FIG. 1, a computer 11 capable of key-inputting image search information is connected to an image recording device 12. The image recording device 12 has a recording medium such as a frame memory and a recording/reproducing head so as to record image signals obtained from, for example, an electronic endoscope and to reproduce the recorded images.

The computer 11 can output a read command signal and an image switching signal in response to the key-in of the search code. The image switching signal output terminal is connected to the synchronization circuit 13 together with the image output terminal of the image recording device 12. This synchronization circuit 13 is provided to synchronize frames, and its output is sent to the switching circuit 14.
and is output to the synchronization signal generation circuit 16. The switching circuit 14 has two switching terminals that are switched by the timing signal of the synchronization circuit 13. An image recording device 12 and a black screen generating section 1 are connected to the switching terminal.
7 are connected respectively. A common terminal of the switching circuit 14 is connected to an image monitor 15. Black screen generation part 1
7 is connected to the output terminal of the synchronization signal generation circuit 16, and can output a black image signal in synchronization with the synchronization signal.

The operation of the above image apparatus will be explained with reference to the flowchart of FIG. In response to the start command, that is, the activation of the playback execution key, the computer 11
outputs an image switching command signal to the synchronization circuit 13. The synchronization circuit 13 inputs a switching timing signal to the switching circuit 14 in response to the switching command signal. The switching circuit 14 switches to the black screen generating section 17 in response to the timing signal. At this time, the synchronization signal generation circuit 16 outputs a synchronization signal to the black screen generation section 17 in response to the output signal of the synchronization circuit 13.
The black screen generator 17 outputs a black image signal synchronized with the synchronization signal. This black image signal is transmitted to the switching circuit 14.
The image is inputted to the image monitor 15 via the image monitor 15 and displayed as a black image.

The computer 11 identifies the optical disk by information read from the system program area of the optical disk by the image recording device 12. This system program area has the following format.

Search conditions, such as patient number, patient name, frame number, etc., are input via the keys of the computer 11. The image recording device 12 executes a data search using a search code according to search conditions. When the track number corresponding to the image to be read is retrieved, the computer 11 supplies a read command signal to the image recording device 12. Image recording device 12 reads image information from the retrieved image recording track of the optical disk in response to the read command signal. When the image information of one image (one frame) is read, the computer 11 outputs a switching command signal, and the synchronization circuit 13
The terminal of the switching circuit 14 is connected to the image recording device 1 via
Switch to the 2nd side terminal. Therefore, image monitor 1
An image signal from an image recording device 12 is input to 5, and a transendoscope image is displayed on this monitor 15. At this time, the synchronizing signal generating circuit 16 stops oscillating in response to the switching command signal. Therefore, the black screen generating section 17 stops generating the black image signal.

Next, for example, when another frame number is input as a search condition, a new frame of image is displayed on the monitor 15 through the same operation as described above.
Note that if the end key is pressed to cancel after the search conditions have been input, the image search and readout will end.

As mentioned above, if the monitor is switched to the black screen generation area and the black image is displayed when the image starts to be played back, unnecessary images will not be displayed before the search, so it will not be possible to misread the image. This does not happen, and the screen does not flicker due to search information.

In the above embodiment, a black screen is displayed, but a white image, a color virtual screen, a gray scale, etc. may be displayed. Further, the image generating section can be configured on the same circuit board as the switching circuit.

[Effects] In addition to the main image output device, an image output means for outputting a fixed pattern of images is provided, and the fixed pattern is displayed before searching for a desired image. Flickering can be avoided.
