    Abstract: A CMOS sensor has unit pixels each structured by a light receiving element and three transistors, to prevent against the phenomenon of saturation shading and the reduction of dynamic range. The transition time (fall time), in switching off the voltage on a drain line shared in all pixels, is given longer than the transition time in turning of any of the reset line and the transfer line. For this reason, the transistor constituting a DRN drive buffer is made proper in its W/L ratio. Meanwhile, a control resistance or current source is inserted on a line to the GND, to make proper the operation current during driving. This reduces saturation shading amount. By making a reset transistor in a depression type, the leak current to a floating diffusion is suppressed to broaden the dynamic range.

    Abstract: When pixels are simply skipped while keeping both an order of pixel information and a spatial positional relation the same as those in all-pixel readout, since a distance between pixels to be read out increases, the Nyquist frequency decreases and aliasing noise increases. A 5×5 pixel block is set as a unit pixel block and pieces of pixel information in first, third, and fifth columns of first, third, and fifth rows of a pixel arrangement are added and outputted as an output in an ath row and an ath column of the unit pixel block. Then, pieces of pixel information in sixth, eighth, and tenth columns of the first, the third, and the fifth rows of the pixel arrangement are added and outputted as an output in the ath row and a bth column of the unit pixel block. Subsequently, pieces of pixel information are added and outputted up to a last column or a column near the last column. Thereafter, pieces of pixel information in the first, the third, and the fifth columns of the sixth, the eighth, and the tenth rows of the pixel arrangement are added and outputted as an output in a bth row and the ath column of the unit pixel block. Subsequently, all arbitrary pixels are read out while repeating the same operation and skipping and adding pieces of pixel information.
