Patent attributes
A solid state imaging device comprising: a pixel region including a matrix of cells; reading means driving a modulation transistor and a residual electric charge discharging control element and carrying out different controls to cells where reading is and is not carried out, in a modulation period when a signal modulation output based on photo-generated electric charges accumulated in a modulation well, and a noise modulation output based on a noise component are obtained; clear means driving the modulation transistor and the discharging control element, and carrying out different controls to cells where a clear is and is not carried out, in a clear period when residual electric charges in the modulation well are discharged; and dummy clear means controlling the clear means, and carrying out control for a cell where the clear is not carried out, to all the cells, before reading a first line from the pixel region.
