Abstract
An image capturing apparatus includes an image sensor configured to change an exposure condition for each of a plurality of exposure areas, each of the exposure areas including a single pixel or a plurality of pixels, and an image processing unit configured to perform steps of digital signal processing on a signal of a captured image includes generating a plurality of coupled areas in which the exposure areas are coupled based on a first threshold of the exposure condition, calculating a development parameter for each of the coupled areas, and applying the development parameter to the image processing unit for each of the exposure areas.
Claims19
An image capturing apparatus, comprising:
- an image sensor configured to change an exposure condition for each of a plurality of exposure areas, each of the exposure areas including a single pixel or a plurality of pixels, wherein the exposure condition includes at least one of an exposure time or an analog gain;
- and
- an image processing unit configured to perform digital signal processing on a signal of a captured image, the digital signal processing comprising:
- generating a plurality of coupled areas in which the exposure areas are coupled based on a first threshold of the exposure condition,
- calculating a parameter for each of the coupled areas, the parameter being used to correct the captured image, and
- correcting the captured image, based on the parameter, for each of the exposure areas.
A method of controlling an image capturing apparatus including an image sensor configured to change an exposure condition for each of a plurality of exposure areas, each of the exposure areas including a single pixel or a plurality of pixels, wherein the exposure condition includes at least one of an exposure time or an analog gain, the method comprising:
- performing digital signal processing on a signal of a captured image;
- generating a plurality of coupled areas in which the exposure areas are coupled based on a first threshold of the exposure condition;
- calculating a parameter for each of the coupled areas, the parameter being used to correct the captured image;
- and
- correcting the captured image, based on the parameter to an image processing unit for each of the exposure areas.
A non-transitory computer-readable storage medium that stores a method of controlling an image capturing apparatus including an image sensor configured to change an exposure condition for each of a plurality of exposure areas, each of the exposure areas including a single pixel or a plurality of pixels, wherein the exposure condition includes at least one of an exposure time or an analog gain, the method comprising:
- performing digital signal processing on a signal of a captured image;
- generating a plurality of coupled areas in which the exposure areas are coupled based on a first threshold of the exposure condition;
- calculating a parameter for each of the coupled areas, the parameter being used to correct the captured image;
- and
- correcting the captured image, based on the parameter, for each of the exposure areas.
