IMAGE PICKUP APPARATUS CAPABLE OF SHOOTING AT HIGH FRAME RATE, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM

摘要

An image pickup apparatus which is capable of obtaining a high-quality image at high speed even when frame rate is high. A frame rate control unit controls frame rate for the shooting. An image decimation unit samples a plurality of images at predetermined time intervals and selects at least two images among the plurality of images as decimation images. A moving vector detection unit detects a moving vector indicative of a moving direction and a moving amount of a subject between the decimation images. A decimation control unit changes decimation conditions according to an absolute value of the moving vector output from the moving vector detection unit. A synthesizing unit aligns the plurality of images based on the output from the moving vector detection unit and then synthesizes the aligned plurality of images to obtain the composite image.
