摘要： An image processing apparatus is provided which performs image restoration as necessary while a computing processing burden based on an image restoration algorithm is reduced. RAW data of a blurred image is input to an RGB interpolation section. The RGB interpolation section generates an R component image, a G component image, and a B component image based on the RAW data. The G component image is input to an image restoration processing section and the R and B component images are input to an RGB to YCC section. The image restoration processing section performs an image restoration process based on a predetermined image restoration algorithm by using a PSF image representing a predetermined point spread function. The RGB to YCC section generates a brightness component image Y and color difference component images CR and CB based on the G component image having been subjected to the image restoration process and the R and B component images which was not subjected to any image restoration process.

摘要： There is provided a technique of preventing occurrence of a shift in white balance even when the ratio of a dark area is greater than the ratio of a bright area as in the case of a night view. A white balance gain calculator calculates white balance gains for an image from color of pixels whose luminance levels are at equal to or greater than a reference luminance level among all pixels of an image. When the ratio of dark pixels whose luminance satisfies a predetermined condition, among all pixels of the image, is equal to or greater than a reference ratio, a correction coefficient calculating section determines a correction coefficient from at least one of factors; namely, image-capturing sensitivity corresponding to an image, the ratio of dark pixels, and firing/non-firing of flash light; and instructs the white balance gain calculator to make a correction to the white balance gain in accordance with the correction coefficient.

摘要： To improve sensitivity by adding pixels, and improve precision of pixel interpolation in an imaging device.An imaging device is provided in which pixels are added along a horizontal direction or a vertical direction to improve sensitivity of an imaging element. An R pixel signal, a G pixel signal, and a B pixel signal in which pixels are added, for example, along the vertical direction are output from a CCD (12). A CFA interpolation unit (24) interpolates the G pixel signal using an adjacent pixel along the horizontal direction. The CFA interpolation unit (24) also interpolates the R pixel signal and the B pixel signal along the horizontal direction using an adjacent pixel along the horizontal direction and interpolates along the vertical direction using correlation of the interpolated G pixel.

摘要： Camera shake which arises during flash (or stroboscopic) photography is corrected. A flashlight-exposed region and an unexposed region are distinguished from each other during flash photography. The flashlight-exposed region is not subjected to camera shake correction, and only the unexposed region is subjected to camera shake correction. After camera shake correction, the flashlight-exposed region having not undergone camera shake correction and the unexposed region having undergone camera shake correction are merged with each other. During merging operation, the flashlight-exposed region is merged over a blending range, thereby blurring a boundary between the regions.
