ABSTRACT:
An image sensor acquires images with resolutions being switched. A resolution switching unit switches the resolutions of the images to be output from the image sensor. An image selecting unit selects a basic image from a plurality of output images which are output from the image sensor, having different resolutions of two or more types switched by the resolution switching unit, at least including an image having a first resolution and an image having a second resolution higher than the first resolution. An image displacement estimating unit estimates a displacement between the basic image and another image. A resolution converting unit converts the resolution of any image in the plurality of output images output from the image sensor using the image having the first resolution and the image having the second resolution acquired by the image sensor and the displacement between images obtained by the image displacement estimating unit.
