    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 pixel signals are separately read from a plurality of horizontal signal lines to achieve high-speed processing, color difference in image signals and stripes are eliminated. In the operation of reading the pixel signals from the (2n)th row, the pixel signals from R pixels on odd columns are output to an output system A through a horizontal signal line (60A). On the other hand, the pixel signals from Gr pixels on even columns are output to an output system B through a horizontal signal line (60B). In the operation of reading the pixel signals from the (2n+1)th row, the pixel signals from Gb pixels on the odd columns are output to the output system B through the horizontal signal line (60B) by the switching operation in a switching circuit (50). Similarly, the pixel signals from B pixels on the even columns are output to the output system A through the horizontal signal line (60A) by the switching operation in the switching circuit (50).
