Abstract:
A large difference in exposure timing is prevented from arising in cases in which plural pixels have a common amplifier, even when image data is read by thinningAn imaging apparatus (10) includes: an image pickup device (14) including plural photoelectric conversion elements arrayed in first and second directions; an amplification means that treats (K×L) pixels as respective common pixels and amplifies an image capture signal for each of the common pixels; a color filter that is provided with a repeatedly disposed basic array pattern or first and second filters placed in a predetermined pattern of (N×M) pixels; and an image processing section (20) and a drive section (22) that perform charge sweeping by applying sequential shutter pulses to the image pickup device (14) in turn to each pixel, or to each scan line, or to each of plural pixels on a scan line, that read pixel signals of the plural pixels at a set cycle, that, from the read pixel signals, generate line image data of pixels that are arrayed running along the second direction at a cycle of from K pixels to N pixels in the first direction, and that generate image data based on the line image data.
Abstract:
For a mosaic image in a repeated cycle with “I”דJ” (“I” and “J” are integers of 2 or more) pixels, a color mix ratio is stored in a memory unit by being associated with a pixel position in I×J pixels so that a color mix ratio A associated with a pixel position in I×J pixels of an object pixel for mixed color correction is read from the memory unit, and a mixed color component included in the object pixel is removed based on the color mix ratio A and a color signal of the object pixel to calculate a white balance gain based on a color signal of each of pixels in the mosaic image for which the mixed color correction is applied.

An image processing method according to an aspect of the present invention includes acquiring a mosaic image composed of pixels of a first color that contributes most to acquisition of a luminance signal among three colors for pixels, and pixels of second colors other than the first color, a first color image corresponding to pixels of the first color and a second color image corresponding to pixels of the second colors having respective different frequency ranges that are reproducible; extracting a region containing a spatial frequency at which the second color image is not reproducible while the first color image is reproducible, in an entire image area corresponding to the mosaic image; and reducing a chroma of an image corresponding to that region in an image acquired by demosaic processing on the mosaic image.
