ABSTRACT:
A hybrid pixel interpolating apparatus (1) has a function of converting raw image data (D1) having one color component for each pixel into pixel interpolated data in which each pixel has a plurality of color components. This hybrid pixel interpolating apparatus (1) includes: a register (2) for holding pixel data in a predetermined pixel region in the raw image data (D1) to be inputted; a plurality of pixel interpolating parts (41, 42, . . . , 4n−1, 4n(n: integer not less than 2)) for sampling pixel data (D2) inputted from the register (2) to execute a pixel interpolating process; and a mixing coefficient calculating part (3) for calculating mixing coefficients (α1, α2, . . . , αn), and also includes a mixing part (5) for fetching and mixing interpolated data (DI1, DI2, . . . , DIn) outputted from the respective pixel interpolating parts (41to4n) to output the resultant. In the mixing coefficient calculating part (3), the mixing coefficients (α1to αn) are calculated for each of the pixel interpolating parts (41to4n) so as to suppress the deterioration in image quality at minimum.
