Abstract: An image processing device includes: a frame memory that saves a cyclic image of an immediately preceding frame as a reference image; and a processor comprising hardware. The processor is configured to: decompose an input image into a plurality of resolution images; set, as a base image, an image having a lower resolution than the input image among the plurality of resolution images and that detects a motion vector between the base image and the reference image; subject the reference image to motion compensation on the basis of the motion vector to generate a motion-compensated image; combine the base image with the motion-compensated image to generate a noise-reduced base image that serves as a new cyclic image; and combine the noise-reduced base image with the resolution image or resolution images other than the base image among the plurality of resolution images.

Abstract: An original image is subjected to reduction processing while minimizing cutting of intrinsically-reproducible frequency bands. A solid-state image-capturing device is provided with: a photoelectric conversion unit that is formed by arraying pixels of a plurality of colors having predetermined color-array periodicity in two-dimensionally, vertically and horizontally; a pixel mixing and reading unit that mixes pixel signals obtained by the photoelectric conversion unit, in each of pixels of the same colors in an n×n (n denotes a desired integer of 2 or more) block, and that outputs multi-channel reduced image signals with a reduction ratio 1/n; and an inter-channel displacement correcting unit that corrects inter-channel displacements of the reduced image signals output by the pixel mixing and reading unit and that outputs corrected reduced image signals.

Abstract: An image-processing device is provided with: a flicker detecting portion that detects a flicker component in an input image signal for each frame and that generates a first signal; a storing portion that stores the generated first signal for a plurality of latest continuous frames; a phase-displacement detecting portion that selects, from the stored past first flicker correction signals, the first signal having substantially the same phase as the most-recent first signal, and that detects a phase displacement level with respect to the most-recent first signal; a phase-displacement correcting portion that corrects the selected past first signal on the basis of the detected phase displacement level; an infinite-impulse-response combining portion that generates a second signal by combining, at a predetermined ratio, the corrected past first signal and the most-recent first signal; and a flicker correcting portion that corrects the input image signal on the basis of the generated second signal.
