Abstract

A first signal processing apparatus includes: an image processing unit configured to at least execute a composition process of generating composed image information in which first image information or second image information and textual information are superimposed; and a control unit configured to control the process of the image processing unit in accordance with communication with a second signal processing apparatus. The control unit selects either one of the first image information and the second image information, and when the second image information is selected, the control unit outputs a first command for instructing the second signal processing apparatus not to superimpose the second image information and the textual information related to the second image information, and causes the image processing unit to generate composite image information in which the second image information and the textual information related to the second image information are superimposed.

First claim

What is claimed is:

1. A first signal processing apparatus to which a first endoscope apparatus including a first image sensor is detachably attached, the first signal processing apparatus being communicably connected to a second signal processing apparatus to which a second endoscope apparatus including a second image sensor is attached, the first signal processing apparatus comprising:
a processor comprising hardware, wherein the processor is configured to:
execute a composition process comprising generating composed image information in which textual information related to second image information is superimposed on the second image information input from the second signal processing apparatus based on the imaging signal generated by the second image sensor of the second endoscope apparatus; and
output a first command for instructing the second signal processing apparatus not to superimpose textual information onto the second image information;
receive, from the second signal processing apparatus, the second image information on which textual information is not superimposed; and
generate composite image information in which the textual information related to the second image information is superimposed on the received second image information.

2. The first signal processing apparatus according to claim 1 ,
wherein the processor is configured to:
select either the first image information or the second image information in accordance with the communication with the second signal processing apparatus, the first image information being based on the imaging signal generated by the first image sensor; and
generate a composed image in which image information selected and textual information related to the image information are superimposed.

3. The first signal processing apparatus according to claim 2 ,
wherein the processor is configured to:
transmit, when communication with the second signal processing apparatus is established, to the second signal processing apparatus the first command and a second command instructing transmission of the second image information to the first signal processing apparatus; and
select the second image information input from the second signal processing apparatus in accordance with the transmission of the second command to the second signal processing apparatus.

4. The first signal processing apparatus according to claim 3 ,
wherein the processor is configured to receive the textual information related to the second image information from an input device connected to the first signal processing apparatus.

5. The first signal processing apparatus according to claim 3 ,
wherein the processor is configured to:
transmit to the second signal processing apparatus a third command instructing transmission of the textual information related to the second image information in addition to the first command and the second command; and
generate a composed image in which the second image information selected and the textual information related to the second image information input from the second signal processing apparatus in accordance with the third command are superimposed.

6. The first signal processing apparatus according to claim 2 ,
wherein the processor is configured to:
perform a correction process on the second image information; and
generate, when the second image information is selected, a composed image in which the second image information and the textual information related to the second image information are superimposed after executing the correction process on the second image information.

7. An endoscope system comprising:
a first signal processing apparatus to which a first endoscope apparatus including a first image sensor is detachably attached; and
a second signal processing apparatus to which a second endoscope apparatus including a second image sensor is attached,
wherein the first signal processing apparatus and the second signal processing apparatus are communicably connected to each other, and
wherein the first signal processing apparatus comprises a processor comprising hardware, wherein the processor is configured to:
execute a composition process comprising generating composed image information in which textual information related to the second image information is superimposed on second image information input from the second signal processing apparatus based on the imaging signal generated by the second image sensor of the second endoscope apparatus;
output a first command for instructing the second signal processing apparatus not to superimpose textual information related to the second image information onto the second image information;
receive, from the second signal processing apparatus, the second image information on which textual information is not superimposed; and
generate composite image information in which the textual information related to the second image information is superimposed on the received second image information.

8. The endoscope system according to claim 7 ,
wherein the processor is configured to receive the textual information related to the second image information from an input device.
