A pixel array within an integrated-circuit image sensor is exposed to light representative of a scene during a first frame interval and then oversampled a first number of times within the first frame interval to generate a corresponding first number of frames of image data from which a first output image may be constructed. One or more of the first number of frames of image data are evaluated to determine whether a range of luminances in the scene warrants adjustment of an oversampling factor from the first number to a second number, if so, the oversampling factor is adjusted such that the pixel array is oversampled the second number of times within a second frame interval to generate a corresponding second number of frames of image data from which a second output image may be constructed.

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.

A capacitance of a first line which transmits a ramp signal having a potential changed by a first changing amount is controlled to be larger than a capacitance of a second line which transmits a ramp signal having a potential changed by a second changing amount which is larger than the first changing amount.
