Abstract:
1. An image processing device comprising: a storing unit storing a position of a focus detecting pixel of an image-capturing sensor which contains a plurality of color pixels having spectroscopic characterizations corresponding to a respective plurality of color components, the focus detecting pixel having a spectroscopic characterization different from the spectroscopic characterizations of the plurality of color pixels; a pixel interpolating unit generating an interpolation color pixel value of the focus detecting pixel by using a pixel value of one of the plurality of color pixels in a neighborhood of the focus detecting pixel in an image generated by the image-capturing sensor; a neighborhood-pixel estimating unit calculating an estimation pixel value corresponding to a pixel value of one of the plurality of color pixels in the neighborhood of the focus detecting pixel if the pixel value of one of the plurality of color pixels were to have the same spectroscopic characterization as the focus detecting pixel; a high frequency component calculating unit calculating a high frequency component of the image by using a pixel value of the focus detecting pixel and the estimation pixel value; and a high frequency component adding unit adding the interpolation color pixel value with the high frequency component to calculate the pixel value of the focus detecting pixel for imaging.
