Solid-state electronic imaging device and method for controlling the same
Abstract:
Provided are a solid-state electronic imaging device that makes periodic noise invisible and a method for controlling the solid-state electronic imaging device. In a solid-state electronic imaging device in which a plurality of photoelectric conversion elements are arranged, a second ramp wave whose level decreases for a second sampling period from the output of a read pulse for reading signal charge accumulated in the photoelectric conversion elements to the output of a reset pulse for resetting the signal charge accumulated in the photoelectric conversion elements is output. In a case in which the level of the second ramp wave is a second reference level, a second sampling pulse is output and a voltage signal converted from the signal charge is sampled. The sampling interval is non-periodic. Even in a case in which periodic noise has an effect on the solid-state electronic imaging device, it is possible to exclude the periodic noise from an object image obtained by imaging.
