Abstract
A camera control device estimates a deterioration degree indicating a degree of deterioration in an image capturing element converting an image of a subject into an electrical signal, and controls parameters related to an amount of exposure to the image capturing element such that the amount of exposure to the image capturing element becomes equal to or smaller than a predetermined amount of exposure when the deterioration degree satisfies a predetermined condition.
Claims20
A camera control device comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor, the memory storing instructions that, when executed by the at least one processor, cause the at least one processor to:
- (1) execute photon number counting processing of counting the number of photons incident on an image capturing element or photon number integrating processing of integrating the number of photons incident on the image capturing element over a predetermined period of time,
- (2) estimate, based on the number of photons counted through the photon number counting processing or the number of photons integrated through the photon number integrating processing, a deterioration degree indicating a degree of deterioration in an image capturing element converting an image of a subject into an electrical signal, and
- (3) control parameters related to an amount of exposure to the image capturing element such that the amount of exposure to the image capturing element becomes equal to or smaller than a predetermined amount of exposure when the deterioration degree satisfies a predetermined condition.
