Abstract:
1. An imaging device, comprising: an image sensor provided with phase detection pixels for focus detection at some of its pixels, a contrast information detection circuit that detects contrast information of a formed image from pixels, among pixel data output from the image sensor, positioned close to the phase detection pixels, a phase detection pixel correction determination circuit that determines whether or not to correct data of the phase detection pixel based on the detected contrast information, a weighting determination circuit that, when it has been determined by the phase detection pixel correction determination circuit that the phase detection pixel will be corrected, determines a weighting for output calculated from outputs of neighboring pixels to the phase detection pixels and gain corrected output of the phase detection pixel based on the detected contrast information, a pixel correction circuit that carries out weighted correction of the phase detection pixels based on the determined weighting, and a color conversion processing circuit that carries out conversion processing for display of the image data or to create an image for storage, after the pixel correction; wherein the contrast information detection circuit detects a difference added value and a difference maximum value of pixels values for neighboring pixels to the phase detection pixel as contrast information.
