<P>PROBLEM TO BE SOLVED: To obtain an image by signals accumulated in a proper period of time when a plurality of regions, each of which has a different density of pixels from which signals are read out, are present in the pixel array in reading a signal out of the pixel array. <P>SOLUTION: The imaging device is equipped with the pixel array in which a plurality of pixels are arranged in the row and column directions, a selection unit which selects a read-out region in the pixel array and a read-out unit which reads a signal out of the read-out region selected by the selection unit. The read-out unit reads a signal out of the whole pixel array, i.e., a first read-out region in a first frame period with a first pixel density upon thinning and reading-out while reading a signal out of a part of the pixel array, i.e., a second read-out region in a second frame period with a second pixel density higher than the first pixel density. The selection unit requires pixels in the first read-out region to effect an electric charge accumulating operation at a first accumulation time and requires pixels in the second read-out region to effect the electric charge accumulating operation at the second accumulation time upon thinning and reading-out. <P>COPYRIGHT: (C)2009,JPO&INPIT |
