Abstract: To improve the resolution of a stationary region while suppressing artifacts in a moving region, an image processing system includes a misalignment-detecting circuit that detects an amount of misalignment between a plurality of time-series images; a high-resolution combining circuit that, based on the amount of misalignment, combines the plurality of images in a high-resolution space having a higher resolution than the plurality of images to generate a high-resolution combined image; an image-converting circuit that reduces the size of the high-resolution combined image by resampling to generate a converted image; a correlation-calculating circuit that calculates the correlation between a standard image serving as a standard among the plurality of images and the converted image for each region; and an image-correcting circuit that corrects the high-resolution combined image such that the combining ratio of the standard image becomes lower as the correlation calculated by the correlation-calculating circuit becomes higher.

Abstract: An image-processing device includes a high-resolution combining portion that generates a combined image by combining a standard image and at least one reference image, which are acquired by capturing images of a subject in time series by using an imaging element in which multiple types of color filters are arrayed in individual pixels, in a high-resolution space where the resolution is greater than those of the standard image and the reference images. The image-processing device also includes a position-displacement-distribution calculating portion that calculates a distribution of position displacements between two comparative images that are individually formed of pixels corresponding to the different types of color filters in the generated combined image, a correlation-level calculating portion that calculates, for individual pixels, correlation levels between the two comparative images based on the calculated distribution, and an image correcting portion that corrects the combined image based on the calculated correlation levels.

Abstract: An image processing device combines a plurality of time-series images to generate a composite image with a higher resolution than a resolution of the plurality of images. The image processing device includes a processor that includes hardware and that is configured to: detect depth information of at least one image of the plurality of images; and set the number of images to be combined for generating the composite image on the basis of the detected depth information. The depth information indicates a depth of a captured scene of the at least one image. The processor is configured to reduce the number of images as the depth of the captured scene increases.
