Patent ID: 7705910

Claim:
A photographic device, comprising: a single image sensor in which a plurality of pixels are arrayed in the form of a matrix; a row selection unit which selects horizontal rows of the single image sensor in order in the vertical direction; a read out unit which reads out electric charge from each pixel of the horizontal rows selected by the row selection unit, after exposure thereof; an imaging unit which forms a whole image of a photographic region upon each of a plurality of pixel regions, each of the plurality of pixel regions being made of a plurality of horizontal rows, the plurality of pixel regions being arranged in the single image sensor in such a manner as to align in the vertical direction; and a light emission control unit which controls the light emission amount of a light source which irradiates the photographic region, according to a pixel region which includes a horizontal row currently selected by the row selection unit; wherein: the read out unit obtains a plurality of whole images in order from the plurality of pixel regions, and creates a single synthesized whole image using these whole images; and the light emission control unit varies the light emission amount of the light source for the pixel region of each image obtained by the read out unit.
