Abstract: Provided are a device and method for controlling a solid-state electronic imaging device which can change the amount of exposure of a photoelectric conversion element without changing the structure of the imaging device. A reset pulse and a read pulse are applied to photoelectric conversion elements included in an imaging device in synchronization with a synchronizing signal. The output interval of the synchronizing signal up to the photoelectric conversion elements in a predetermined row is ?H1 and is constant. For the photoelectric conversion elements in the subsequent rows, the output interval of the synchronizing signal is ?H2 that is longer than ?H1. Since the reset pulse and the read pulse are synchronized with the synchronizing signal, the output interval of the synchronizing signal is long. It is possible to adjust the amount of exposure of the photoelectric conversion element.

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 noise data update processing unit calculates the amount of a fixed pattern noise component on the basis of a detection signal of infrared rays detected by an infrared detector in a state where an optical system is controlled to be in a non-focused state, and updates an FPN data storage unit with the calculated amount of the FPN component. The noise data update processing unit calculates an average value of detection signals of each detector element and a plurality of peripheral detector elements, and calculates a signal component dependent on incident infrared rays included in the detection signal of each detector element by subtracting an average value of fixed pattern noise data before update from the calculated average value. The amount of the fixed pattern noise component is calculated by subtracting the calculated signal component from the detection signal of each detector element.
