摘要:
There is a problem in that when magnification chromatic aberration correction is carried out, the difference in reproducibility of high-frequency components, depending on the spatial position, between a color for which position shift correction is not performed and a color for which position shift correction is performed may influence the image quality of an output image. In order to perform magnification chromatic aberration correction, high-frequency components, which are lost due to the position shift correction of a color for which position shift correction is carried out, are extracted from a color for which position shift correction is not carried out, and are added to the color for which position shift correction is carried out. Therefore, the high-frequency components are restored in a pseudo manner.

An image processing apparatus can execute appropriate image processing while preventing increase in a capacity of a memory for storing a plurality of pieces of image data of different frequency bands. The image processing apparatus stores first image data having the highest frequency among the plurality of pieces of image data of different frequency bands in a state in which each pixel of the first image data includes a color component signal of any of a plurality of colors, on the memory, and further stores second image data and third image data whose frequency bands are lower than that of the first image data on the memory, in a state in which a part of or all pixels of the second and the third image data have color component signals of a plurality of colors.
摘要:
An image sensing apparatus comprises an image sensing unit including an image sensor having a plurality of image sensing pixels and a plurality of focus detection pixels discretely arranged between the plurality of image sensing pixels, a shift detection unit that detects a shift amount between images obtained by a plurality of image sensing operations, a combining unit that combines signals of the focus detection pixels contained in the images obtained by the plurality of image sensing operations on the basis of the shift amount detected by the shift detection unit, and a focus adjustment unit that adjusts a focus of the imaging lens by using signals of the focus detection pixels before combined by the combining unit, and signals of the focus detection pixels that are combined by the combining unit.
