Abstract:
1. A solid-state image pickup device comprising: an imaging region which includes a plurality of pixels each having a photodiode that generates electric charge of an amount according to an incident light amount and a charge storing section storing the electric charge, the imaging region storing electric charge generated in the photodiode in each of the plurality of pixels by the charge storing section during a period instructed by a controlling signal of a charge storing operation; a triggering photosensitive region which includes a triggering photodiode that generates electric charge of an amount according to an incident light amount; and an output section including: a controlling section to which the triggering data output from the output section is input, the controlling section generating the controlling signal of the charge storing operation, which instructs each of the plurality of pixels in the imaging region to perform a charge storing operation when an absolute value of the triggering data is greater than a threshold value, the controlling section outputting a clock signal synchronized with the output timing of each bit of each of the pixel data and the triggering data by the output section, wherein the triggering A/D converting circuit operates with lower power consumption than a lower power consumption by the imaging A/D converting circuit outputting the pixel data, and the triggering A/D converting circuit also operates with lower speed than a speed of the imaging A/D converting circuit outputting the pixel data.
