摘要： When processing an image of a two-dimensional pixel arrangement such as a Bayer arrangement, when a pixel G (j, i) of a first color component which represents luminance is interpolated, the value of the first color component associated with the primary reference pixels located adjacent to the top and bottom or left and right of the interpolated pixel position, and secondary reference pixels of the first color component, located in the vicinity of the primary reference pixel, is checked. The existence of an image edge component is detected. When an image edge component is detected, the weight of the reference pixels, for example, G(j−1, i), G(j+1, i), G(j, i−1) and G(j, i+1) is changed at the top, bottom, left and right.

摘要： A CCD captures a subject image having passed through a taking lens and an image processing circuit performs various types of image pre-treatment including gamma correction and white balance on image data corresponding to n lines×m rows output by the CCD. The image processing circuit also performs format processing on the data. The data are then compressed at a compression circuit. The white balance adjustment and the like are implemented in line sequence at a line processing circuit which engages in signal processing in pixel sequence in units of individual lines in the output from the CCD. The image data having undergone the pre-treatment are then subjected to format processing prior to JPEG compression, at a block processing circuit that engages in signal processing in units of individual blocks each ranging over an n×m (N>n, M>m) block. In other words, the signal processing is performed in block sequence.
