1. An image capture system comprising: an image capture device configured to sequentially capture an object image by a single sensor and sequentially outputting a plurality of frame images including at least a first frame image and a second frame image, wherein the second frame image sequentially follows the first frame image with no intervening frames; a plurality of image processing devices configured to perform a still image processing; and a distribution device for distributing the plurality of frame images from the image capture device to the plurality of image processing devices in unit of single frame, wherein, in a continuous still image shooting mode for sequentially capturing the object image to output the first frame image and to output the second frame image next to the first frame image, a first image processing device among the plurality of image processing devices processes the first frame image and outputs the processed first frame image to be recorded as one still image during the time when a second image processing device among the plurality of image processing devices processes the second frame image sequentially following the first frame image with no intervening frames and directly, without going through the first image processing device, outputs the processed second frame image to be recorded as one still image.
