Abstract

An endoscope system includes a first processor and a second processor. The first processor is configured to receive an information including a number of times an endoscope is used, and determine if the number of times the endoscope is used is equal to or larger than a predetermined number of times. The second processor is configured to overwrite a first image correction data with a second image correction data when the first processor determines the number of times the endoscope is used is equal to or larger than the predetermined number of times.

First claim

What is claimed is:

1 . A control device for use with an endoscope, comprising:
at least one processor configured to:
receive an information including a number of times the endoscope is used;
determine if the number of times the endoscope is used is smaller than or equal to or larger than a predetermined number of times;
in response to determining the number of times the endoscope is used is smaller than the predetermined number of times, generate a first image; and
in response to determining the number of times the endoscope is used is equal to or larger than the predetermined number of times, generate a second image,
wherein a first visibility of the first image is higher than a second visibility of the second image, wherein the first visibility and the second visibility depend on a timing to read endoscopic image data from the endoscope.

2 . The control device according to claim 1 , wherein in response to determining the number of times the endoscope is used is equal to or larger than the predetermined number of times, the at least one processor is configured to overwrite a first image correction data with a second image correction data,
wherein the first image is generated based on an image signal and the first image correction data, and wherein the second image is generated based on the second image correction data.

3 . The control device according to claim 2 , wherein the at least one processor comprises a first processor and a second processor,
wherein the first processor is configured to receive the information including the number of times the endoscope is used and determine if the number of times the endoscope is used is equal to or larger than the predetermined number of times, wherein the second processor is configured to overwrite the first image correction data with the second image correction data, and wherein the control device further comprises a video processor.

4 . The control device according to claim 3 , wherein the endoscope further includes a first memory, and
wherein the first memory is configured to store one of the first image correction data and the second image correction data.

5 . The control device according to claim 4 , wherein the endoscope further includes a second memory, and
wherein the second memory is configured to store the information including the number of times the endoscope is used.

6 . The control device according to claim 5 , wherein the at least one processor is further configured to:
detect a connection between the endoscope and the video processor, and receive the information including the number of times the endoscope is used from the second memory.

7 . The control device according to claim 2 , further comprising an adapter connected to the endoscope and the at least one processor,
wherein the at least one processor includes a first processor and a second processor, wherein the first processor is configured to receive the information including the number of times the endoscope is used and determine if the number of times the endoscope is used is equal to or larger than the predetermined number of times, wherein the second processor is configured to overwrite the first image correction data with the second image correction data, and wherein the adapter includes the second processor.

8 . The control device according to claim 1 , further comprising a video processor, wherein the video processor includes the at least one processor.

9 . The control device according to claim 1 , wherein, when the first visibility of the first image is higher than the second visibility of the second image, the at least one processor is configured to at least one of:
(i) obtain the second image including a number of a defective pixel that is higher than a number of a defective pixel included in the first image; (ii) shift a timing to read endoscopic image data from a timing to read endoscopic image data to obtain the first image; (iii) obtain the second image to be smaller or larger than the first image; (iv) obtain the second image including a white balance different from a white balance of the first image; (v) obtain the second image by using endoscopic image data obtained by a maximum exposure period, (vi) obtain the second image having a different size from the first image; or (vii) obtain the second image having a different exposure from the first image.

10 . The control device according to claim 1 , wherein the at least one processor is configured to obtain the second image including a number of a defective pixel that is higher than a number of a defective pixel included in the first image.

11 . The control device according to claim 1 , wherein the at least one processor is configured to output one of the first image or the second image to a display that is different from the endoscope.

12 . The control device according to claim 1 , wherein the at least one processor is configured to:
determine whether to finish processing; and in response to determining the number of times the endoscope is used is equal to or larger than the predetermined number of times, and in response to determining the processing is finished, overwrite a first image correction data with a second image correction data.

13 . The control device according to claim 12 , wherein the at least one processor is configured to generate one of the first image or the second image in response to determining the processing is not finished.

14 . An image generation method, comprising:
receiving information including a number of times an endoscope is used; determining if the number of times the endoscope is used is smaller than or equal to or larger than a predetermined number of times; in response to determining the number of times the endoscope is used is smaller than the predetermined number of times, generating a first image; and in response to determining the number of times the endoscope is used is equal to or larger than the predetermined number of times, generating a second image, wherein a first visibility of the first image is higher than a second visibility of the second image, wherein the first visibility and the second visibility depend on a timing to read endoscopic image data from the endoscope.

15 . The image generation method according to claim 14 , wherein, in response to determining the number of times the endoscope is used is equal to or larger than the predetermined number of times, the method further comprises:
overwriting a first image correction data with a second image correction data, wherein the first image is generated based on an image signal and the first image correction data.

16 . The image generation method according to claim 15 , wherein the second image is generated based on the second image correction data.

17 . The image generation method according to claim 14 , further comprising:
outputting one of the first image or the second image to a display that is different from the endoscope.

18 . A non-transitory computer-readable medium having instructions stored thereon, which when implemented by a processor causes the processor to execute a method, the method comprising:
receiving information including a number of times an endoscope is used; comparing the number of times the endoscope is used to a predetermined number of times; and in response to determining the number of times the endoscope is used is smaller than the predetermined number of times, generating a first image, in response to determining the number of times the endoscope is used
