Abstract

An endoscope video apparatus has an endoscope including a solid-state image sensor, for outputting an endoscopic image signal, a video processor for processing the image signal supplied from the solid-state image sensor and outputting a video signal, an image file unit for recording the video signal, and an input section for inputting retrieval data corresponding to the video signal recorded in the image file unit. A control section discriminates the presence/absence of retrieval data input from the input section. A control circuit operates an alarm unit by discrimination data representing the absence of retrieval data.

Claims

1. An endoscope video apparatus comprising:

image signal output means, provided to an endoscope, for outputting an endoscopic image signal;

video processing means for processing the image signal and outputting a video signal;

video recording means for recording the video signal from said video processing means;

input means for inputting retrieval data corresponding to the video signal recorded in said video recording means;

informing means for informing the retrieval data to said video recording means;

discriminating means for discriminating presence/absence of the retrieval data from said input means and outputting discrimination data; and

means for outputting alarm data in response to the discrimination data representing absence of retrieval data from said discriminating means.

2. An apparatus according to claim 1, wherein said informing means includes communication means for transmitting the retrieval data from said input means to said video recording means.

3. An apparatus according to claim 1, wherein said video processing means includes character output means for outputting character data, said video recording means for recording the video signal, and means for combining the character data with the video signal and outputting an obtained composite image signal.

4. An apparatus according to claim 3, wherein said character data output means has a memory for storing retrieval data input from said input means and readout means for reading out the retrieval data from said memory.

5. An apparatus according to claim 1, wherein said discriminating means includes means for recording the retrieval data input by said input means, and means for identifying the retrieval data in said recording means and outputting to said video recording means an image-recording enable signal together with the retrieval data through said informing means.

6. An apparatus according to claim 5, wherein said alarm data output means comprises a sound producing member for producing an alarm in response to the discrimination data representing the absence of retrieval data.

7. An apparatus according to claim 1, wherein said video recording means has a recording means for recording a video signal, detecting means for detecting a number of recordable frames, comparing means for comparing the number of frames detected by said detecting means with a predetermined number of frames, and means for inhibiting video recording by said video recording means in response to resultant data supplied from said comparing means and representing that the number of recordable frames is not more than the predetermined number.

8. An apparatus according to claim 7, wherein said inhibiting means has means for displaying a message representing inhibition of video recording.

9. An apparatus according to claim 1, further comprising means for outputting a specific image signal different from the endoscopic image signal, and wherein said video processing means has means for performing selective switching between the endoscopic image signal and the specific image signal and outputting a selected signal to said display means.

10. An apparatus according to claim 9, wherein said switching means is means for guiding the specific image signal corresponding to a specific image to said display means in response to start of readout of the video signal from said video recording means.

11. An apparatus according to claim 9, wherein said specific image output means is means for outputting an image signal representing a black image.

12. An apparatus according to claim 9, wherein said specific image output means is means for outputting an image signal representing a white image.

13. An apparatus according to claim 9, wherein said specific image output means is means for outputting an image signal representing a color bar chart.

14. An apparatus according to claim 9, wherein said specific image output means is means for outputting an image signal representing a gray scale chart.

15. An apparatus according to claim 9, further comprising means for synchronizing said specific image output means with said endoscopic image output means, and wherein said switching means is means operative in synchronism with a sync signal of an image signal supplied from said endoscopic image output means.

16. An apparatus according to claim 9, wherein said specific image output means and said switching means are formed on a single circuit board.

17. An apparatus according to claim 9, wherein said means for outputting a specific image signal includes means for producing a signal representing a message superimposed on the specific image.
