Abstract
A sensed image generated from an image signal output from an image sensor for receiving light that becomes incident sequentially through an imaging lens and a microlens array that is a two-dimensional array including a plurality of microlenses is acquired. A list is created in which, for each pixel position on the image sensor, the correspondence between the coordinates of the light incident at the pixel position on the imaging lens and the coordinates of the pixel position is registered. Images obtained by rearranging pixels at the coordinate positions on the image sensor corresponding to the coordinates in accordance with the arrangement order of the coordinates on the imaging lens are generated as a parallax image group.
Claims7
An image sensing apparatus comprising:
- an image acquisition unit that acquires a sensed image generated from an image signal output from an image sensor for receiving light that becomes incident sequentially through an imaging lens and a microlens array that is a two-dimensional array including a plurality of microlenses, wherein each of the plurality of microlenses corresponds to any one of pixel groups in the image sensor and each pixel in the pixel group receives the light that has passed through corresponding microlens;
- an parameter acquisition unit that acquires an image sensing unit parameter corresponding to the sensed image;
- and
- a generation unit that generates a display image including a plurality of parallax images based on the image sensing unit parameter, wherein the parallax images are generated from the sensed image and the number of parallax images included in the display image is determined based on the number of pixels included in areas, corresponding to the plurality of microlenses, in the sensed image.
