摘要： A system and method for driving a solid-state image pickup device including a pixel array unit including unit pixels. Each unit pixel includes a photoelectric converter, column signal lines and a number of analog-digital converting units. The unit pixels are selectively controlled in units of rows. Analog signals output from the unit pixels in a row selected by the selective control though the column signal lines are converted to digital signals via the analog-digital converting units. The digital signals are added among a number of unit pixels via the analog-digital converting units. The added digital signals from the analog-digital converting units are read. Each unit pixel in the pixel array unit is selectively controlled in units of arbitrary rows, the analog-distal converting units being operable to performing the converting in a (a) normal-frame-rate mode and a (b) high-frame-rate mode in response to control signals.

摘要： Provided is a solid-state imaging element including pixel signal read lines, and a pixel signal reading unit for reading pixel signals from a pixel unit via the pixel signal read line. The pixel unit includes a plurality of pixels arranged in a matrix form, each pixel including a photoelectric conversion element. In the pixel unit, a shared pixel in which an output node is shared among a plurality of pixels is formed, and a pixel signal of each pixel in the shared pixel is capable of being selectively output from the shared output node to a corresponding one of the pixel signal read lines. The pixel signal reading unit sets a bias voltage for a load element which is connected to the pixel signal read line and in which current dependent on a bias voltage flows in the load element, to a voltage causing a current value to be higher than current upon a reference bias voltage when there is no difference between added charge amounts, when addition of pixel signals of the respective pixels in the shared pixel is driven.
