    摘要: An image processing apparatus for processing complementary color image data output from an image capturing element including a complementary-color filter is provided. The apparatus comprises a middle-high-range luminance component compensation section for compensating for a middle-high-range luminance component of a low-frequency luminance signal generated based on the complementary color image data such that the low-frequency luminance signal has substantially an ideal frequency characteristic which is lower than or equal to a predetermined frequency.

    摘要: A plurality of interlaced video signals respectively corresponding to a plurality of continuous fields are generated by first, second, and third one-field delay circuits on the basis of an inputted interlaced video signal. A first progressive video field signal is generated by a first progressive video generation circuit on the basis of the plurality of interlaced video signals. A second progressive video field signal is generated by a second progressive video generation circuit on the basis of the plurality of interlaced video signals. Motion amount information in the vertical direction of a picture is calculated by a comparison circuit on the basis of the first progressive video field signal and the second progressive video field signal.

    摘要: A first video signal generation circuit newly generates pixels between pixels in a first progressive video field signal outputted by a first progressive video generation circuit, and outputs a third progressive video field signal. A second video signal generation circuit newly generates pixels between pixels in a second progressive video field signal outputted by a second progressive video generation circuit, and outputs a fourth progressive video field signal. A comparison circuit compares the third progressive video field signal and the fourth progressive video field signal, and outputs the result of the comparison as motion amount information. An output circuit synthesizes an intra-field interpolation signal and a frame interfiled interpolation signal on the basis of the motion amount information, and outputs a composite signal as a progressive video signal.
