Abstract
An image processing apparatus includes a calculation circuit configured to calculate a disparity between images, a determination circuit configured to determine a pixel position at which intensive disparity retrieval is to be performed based on distribution statistics of the disparity, an interpolation circuit configured to generate an interpolated image by performing interpolation at pixel positions at which intensive disparity retrieval is to be performed, and an output circuit configured to output a corrected disparity with which the distance to the object is determined. The calculation circuit calculates a first disparity based on the first and second images and generate distribution statistics from the first disparity in the first image, and calculates a second disparity based on the second image and the interpolated image generated from the first image by the interpolation circuit. The output circuit generates the corrected disparity based on differences between the first and second disparities.
