摘要： A demosaicing unit interpolates mosaic image data of each pixel of interest so as to reproduce colors missing at each pixel by interpolation using neighboring pixels. In the demosaicing unit, an interpolation unit performs an interpolation process in a plurality of prescribed directions using neighboring pixels in the prescribed directions. An evaluation unit evaluates image data in each prescribed directions interpolated by the interpolation unit. A spurious resolution area judgment unit judges whether a pixel is in a spurious resolution area, on a pixel-by-pixel basis, based on a saturation detected from image data subjected to an interpolation process performed so as to preserve an edge component. An image generation unit selects image data to be interpolated for each pixel based on a result of the evaluation by the evaluation unit and a result of the judgment by the spurious resolution area judgment unit, and generates interpolated image data.

摘要： Disclosed is an image processing apparatus for converting an original image. Processing of blurring an input original image is performed to generate a blurred image. A difference image that is the difference between the original image and an adjusted image obtained by adjusting the density of the blurred image is generated. The difference image and the original image are composited based on the density of the difference image and the density of the original image. This allows to easily obtain a painting-like effect even in, for example, a low-contrast portion of an image.

摘要： A generation unit generates, from a first image, a second image from which a first frequency component of the first image has been removed. A correction unit generates a first correction image by adding, to the first image, a first correction component that is based on the first frequency component of the first image and a second frequency component corresponding to a lower band of the first image than the first frequency component, and generates a second correction image by adding, to the second image, a second correction component that is based on the second frequency component. The first correction component includes a component obtained by applying a first gain to the second frequency component. The second correction component includes a component obtained by applying a second gain larger than the first gain to the second frequency component.

摘要： At least one image processing apparatus is provided which allows performing a demosaicing process on a polychrome image signal with high accuracy. The at least one image processing apparatus performs an interpolation process in each of a plurality of defined directions on a mosaic image signal and acquires an evaluation value representing a correlation in each of a horizontal direction and a vertical direction for each of a plurality of pixels of the image signal having undergone the interpolation process. The evaluation values for at least one pixel of interest are corrected based on the evaluation values for peripheral pixels if a predetermined condition including a condition that it is determined that the at least one pixel of interest is an isolated point is satisfied. Then, the image signal after the at least one pixel of interest is interpolated based on the corrected evaluation values.
