Abstract
An image processing apparatus includes an intermediate image generating unit configured to input an image which has been shot with differing exposure times set by region, generates a plurality of exposure pattern images corresponding to differing exposure times based on the input image, and generates a plurality of timing images which are difference images of the plurality of exposure pattern images; and a distortion correction processing unit configured to generate a corrected image equivalent to an exposure processing image at a predetermined exposure time by synthesizing processing of the plurality of timing images.
Claims8
A system comprising:
- an imaging apparatus configured to have a plurality of pixels which are arranged in pixel groups, each of the pixel groups having at least two pixels;
- and
- one or more processors configured to:
- generate an image based on each pixel signal from each pixel group of the pixel groups,
- wherein each pixel group of the pixel groups has different exposure times;
- input the image which has been shot with different exposure times set by region;
- generate a plurality of exposure pattern images corresponding to the different exposure times based on the input image;
- generate, from the plurality of exposure pattern images, a plurality of difference images;
- and
- generate a corrected image by synthesizing the plurality of difference images having different exposure starting times within a set interval.
