摘要： An image capture device which can reduce low-frequency noise even circuitry of a small scale is provided. An image capture device includes: an acquisition section which is used to acquire sensitivity information concerning a sensitivity; an imager for generating first image data; a zoom section for changing a size of an image which is based on input image data, the zoom section outputting second image data which is obtained by reducing a size of an image represented by the first image data; and a noise suppression section for outputting third image data which is obtained by reducing noise in an image represented by the second image data. In accordance with the sensitivity information, the zoom section changes a zoom factor by which to reduce the size of the image represented by the first image data.
