Document Type and Number:
Japanese Patent JP2015171049
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an imaging device that can stop light exposure at a proper timing.SOLUTION: An imaging device 10 includes: an OB pixel portion 102 having plural pixels 201 arranged in a matrix form and light-shielded pixels arranged on plural lines out of the plural pixels 201, and an effective pixel portion 101 having pixels 201 out of the plural pixels 201, the pixels 201 being arranged so that light from a subject is incident to the pixels 201; an exposure controller 130 for exposing the effective pixel portion 101 to light; a reading line selecting portion 140 for successively selecting pixel lines of the OB pixel portion 102 at plural different timings during light exposure of the effective pixel portion 101, and outputting pixel signals from the respective pixels 201 of the selected pixel line; and a dark current component measuring portion 150 for measuring a dark charge generated from dark current of a solid imaging element 100 by using a pixel signal every time the pixel signal is output from the OB pixel portion 102 by the selection of the reading line selecting portion 140.
