Abstract:
1. An image sensing apparatus that outputs an image of an object, comprising: an image sensing device including a photoelectric conversion element that photoelectrically converts an optical image to acquire image data, and a readout control unit that reads out, in accordance with a supplied readout rule, the image data acquired by the photoelectric conversion element; an image scaling ratio selection unit that selects a scaling ratio of the image to be output; a readout scheme selection unit that selects, in accordance with the selected image scaling ratio, a readout scheme of the image data to be read out from the photoelectric conversion element by the readout control unit; and a readout rule supply unit that supplies, to the readout control unit, a readout rule corresponding to the readout scheme selected by the readout scheme selection unit; and wherein the readout scheme includes a thinning readout mode, an averaging readout mode, and a full pixel readout mode, the readout scheme selection unit selects one readout scheme of the thinning readout mode, averaging readout mode, and full-pixel readout mode in accordance with the selected image scaling ratio, and the readout rule supply unit includes a thinning readout rule setting unit that sets a readout rule corresponding to the thinning readout mode, an averaging readout rule setting unit that sets a readout rule corresponding to the averaging readout mode, and a full-pixel readout rule setting unit that sets a readout rule corresponding to the full-pixel readout mode.
