Title:
SOLID-STATE IMAGING APPARATUS AND ESTIMATION METHOD OF APPROPRIATE EXPOSURE
Document Type and Number:
Japanese Patent JP2015171139
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a solid-state imaging apparatus which can shorten convergence time of automatic exposure when a camera is started and to provide an estimation method of appropriate exposure.SOLUTION: A sensor section 2 includes: a pixel region section 11 including a plurality of pixels which are two-dimensionally arranged in a matrix; a timing generator 14 for controlling exposure time of a plurality of rows so that the exposure time of the pixels differ between the rows; a comparator 16 for comparing an integrated value of pixel data for each row, in which the exposure time is controlled, with a prescribed value; and a register 17 for holding exposure time information of the row where the integrated value and the prescribed value are matched as a result of the comparison.
