摘要： There is provided with an image capturing device. An image capturing unit is capable of controlling an exposure condition for each region. A first acquisition unit acquires information representing a moving object region within an imaging range of the image capturing unit. A second acquisition unit acquires brightness information of each region within the imaging range of the image capturing unit. A setting unit sets the exposure condition used by the image capturing unit for each region by using the information representing the moving object region and the brightness information.

摘要： An image capturing apparatus comprises an image sensor that outputs a first added signal and a first average partial signal amplified by a first gain, and a second added signal and a second averaged partial signal amplified by a second gain, a processing unit that generates a third added signal by synthesizing the first and second added signals with a first ratio and a third averaged partial signal by synthesizing the first and second averaged partial signals with a second or third ratio, a determination unit that determines the first ratio based on the first or second added signal and determines the second ratio based on the first ratios, and changes the second ratio of a pixel group that includes a pixel corresponding to the saturated first or second added signal to the third ratio, which is not based on the first ratio.

摘要： At least one image processing apparatus, and at least one method, of the present invention(s) generate a corrected image obtained by removing, from a color image whose pixel values contain components derived from scattered light, at least part of the components derived from the scattered light. The at least one image processing apparatus includes a generation unit configured to generate the corrected image by correcting a pixel value of a first color component of each pixel in the color image by using a first reference intensity and a weight value, and by correcting a pixel value of a second color component of each pixel in the color image by using a second reference intensity and a weight value.
