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.

Abstract: A regulated supply voltage can be established using switching cycles defined at least in part according to a switching clock period. Imaging information can be acquired from an imaging sensor and a discrete-time representation of the imaging information can be received. Noise, such as corresponding to the switching cycles, can be reduced or suppressed. In an example, a discrete-valued noise template can be stored in a memory, wherein a count of values in the noise template is less than a count of an entirety of a physical row of pixels from the imaging sensor. The discrete-valued noise template can be aligned with a portion of the discrete-time representation of the imaging information. The noise in the discrete-time representation can be at least partially canceled using the aligned discrete-valued noise template. The template can be constructed such as by aggregating imaging information obtained from an optically-black portion of the imaging sensor.

Abstract: Provided is an imaging apparatus including an imaging element including a pixel unit having first and second photoelectric conversion units configured to generate image signals by photoelectrically converting optical fluxes passing through different regions into which an exit pupil of an imaging optical system is divided for one micro-lens. The imaging apparatus controls each of the timing of a first removal operation of removing a noise component from a first image signal read from the first photoelectric conversion unit and the timing of a second removal operation of removing a noise component from a second image signal read from the first and second photoelectric conversion units to have a predetermined relationship with a frequency of a noise source occurring during an operation of reading the image signals.
