Abstract:
An image sensing apparatus having a color image sensor and shifting means for shifting an image formation position on said color image sensor, where said color image sensor senses an image of an object formed at each image formation position shifted by said shifting means, said apparatus comprising:determination means for determining whether the object is a color object for which a color image sensing operation is suitable or the object is a black-and-white object for which a black-and-white image sensing operation is suitable; shifting control means for controlling said shifting means to perform a first pixel shifting method so as to sense a first number of plural images to be synthesized, in a first sequence in a case where the object is a color object and to perform a second pixel shifting method so as to sense a second number of plural images to be synthesized, in a second sequence in a case where the object is a black-and-white object in accordance with a determination result by said determination means, wherein a set of images sensed in the first pixel shifting method in said first sequence is different from a set of images sensed in the second pixel shifting method in said second sequence; and luminance component extraction means for extracting luminance signals from color component data of each color of a filter provided on said color image sensor when the object is determined to be a black-and-white object by said determination means.
