  • Semiconductor device, physical information acquiring apparatus, and signal reading-out method
    Patent number: 9398238
    Abstract: A semiconductor device includes: an element array portion in which unit elements are disposed in a matrix; and a signal processing portion including a signal processing circuit executing predetermined signal processing based on unit signals outputted from the circuit elements, respectively, every column, in which a function of the signal processing circuit is controlled in such a way that power consumption of the signal processing circuit concerned corresponding to the unit elements each not required becomes lower in a phase of an element selection mode in which only information on a part of the unit pixels for one row in the element array portion is required than in a phase of a normal operation mode.
    Type: Grant
    Filed: February 6, 2015
    Date of Patent: July 19, 2016
    Assignee: Sony Corporation
    Inventors: Shinya Nomura, Yoshiaki Urakawa, Youji Sakioka
