Abstract:
1. A camera apparatus comprising: a solid-state imaging device having a pixel section comprised of a plurality of unit pixels, each unit pixel having a transfer transistor for transferring a signal of an optoelectric transducer to a floating diffusion section, an amplifier transistor for outputting a signal of said floating diffusion section to a signal line, and a resetting transistor for resetting said floating diffusion section; an opticalsy system for guiding incident light onto pixels of said solid-state imaging device; and a driving means which selects pixels in each column and which selects a pixel during a read-out period for a currently selected row by controlling voltages of a drain and a gate of said resetting transistor of the selected pixel and for substantially reducing a bias current flowing to a low channel pixel of each column during a non-reading period by causing the bias current to flow to a location other than low channel pixels of the imaging device.
