Abstract
An image processing apparatus processes image data captured by an image sensor that allows setting of an exposure value for each region of the image sensor, and sets the exposure value for each region based on a magnitude of luminance contrast in each region.
Claims7
An image processing apparatus configured to process image data captured by an image sensor that allows setting of an exposure value for each region of the image sensor, the image processing apparatus comprising:
- at least one memory storing instructions;
- and
- at least one processor executing the instructions causing the processor to:
- set the exposure value for each region based on a magnitude of luminance contrast in each region;
- calculate the exposure value for each region;
- and
- correct the exposure value calculated based on the magnitude of luminance contrast in each region,
- wherein the exposure value set is corrected, and the luminance contrast is calculated based on a difference between a first pixel value and a second pixel value for each region.
An image processing method for processing image data captured by an image sensor that allows setting of an exposure value for each region of the image sensor, the image processing method comprising:
- setting the exposure value for each region based on a magnitude of luminance contrast in each region;
- calculating the exposure value for each region;
- and
- correcting the exposure value calculated based on the magnitude of luminance contrast in each region,
- wherein the exposure value is corrected, and the luminance contrast is calculated based on a difference between a first pixel value and a second pixel value for each region.
A non-transitory storage medium storing a program causing an image processing apparatus configured to process image data captured by an image sensor that allows setting of an exposure value for each region of the image sensor to execute an image processing method, the image processing method comprising:
- setting the exposure value for each region based on a magnitude of luminance contrast in each region;
- calculating the exposure value for each region;
- and
- correcting the exposure value calculated based on the magnitude of luminance contrast in each region,
- wherein the exposure value is corrected, and the luminance contrast is calculated based on a difference between a first pixel value and a second pixel value for each region.
