  • Patent number: 8223410
    Abstract: The present invention relates to an imaging device and a method of processing an imaging result in an imaging device, and is applied to e.g. an electronic still camera to thereby allow the camera to correct image quality readily and flexibly with avoiding the deterioration of the image quality effectively. In the present invention, a three-dimensional look-up table is provided and an imaging result (Y2, Cb2, Cr2) is corrected by use of the three-dimensional look-up table.

  • Patent number: 7321685
    Abstract: The present invention provides an image processing device for correcting aberrations caused by a capturing lens for an image signal to which light passing through the capturing lens is electrically converted. The image processing device includes a correction vector calculation unit for calculating a correction vector in accordance with coordinates of each pixel of each color component contained in the image signal on the basis of at least data on chromatic aberration and distortion aberration caused by the capturing lens; a conversion ratio calculation unit for receiving at least the image signal, capturing conditions, and the correction vector, and for calculating a conversion ratio for scaling the color component in accordance with the coordinates of the pixel; and a resolution conversion unit for scaling the color component in accordance with the coordinates of the pixel on the basis of the conversion ratio.
