<P>PROBLEM TO BE SOLVED: To efficiently converge a black level read out from an OB pixel to a target value even when deviation of the black level read out from the OB pixel is large. <P>SOLUTION: A black level adjustment control device comprises: an analog gain range determination unit 17 that determines to which range analog gain GA for setting an amplification factor for a pixel signal read out from a pixel belongs; a clamp parameter control condition setting unit 18 that sets a control condition for a clamp parameter PC for setting a black level on the basis of a determination result by the analog gain range determination unit 17; and a clamp parameter control unit 16 that controls the clamp parameter PC on the basis of the control condition set by the clamp parameter control condition setting unit 18. <P>COPYRIGHT: (C)2013,JPO&INPIT |
