Patent ID: 7920147

Claim:
An image processing apparatus comprising: a video signal input section configured to receive a YUV 422 video signal having a plurality of first components which are members of a YUV color space, the first components of the YUV 422 video signal inputted into a GPU buffer originally provided for a signal with a plurality of corresponding second components which are members of an RGB color space, wherein areas of the GPU buffer may be associated with any YUV component, such that values of the Y, U, and V components are directly supplied to R, G, and B areas in the GPU buffer, respectively; a signal interface section configured to upsample the YUV 422 video signal to a YUV 444 video signal and to supply a signal converting section with the YUV 444 video signal as a substitute for the signal having a value represented in the RGB color space; and the signal converting section configured to perform predetermined conversion processing on the YUV 444 video signal and the predetermined conversion processing is performed on the YUV 444 video signal without a color space conversion, and after the signal converting section performs the predetermined conversion processing on the YUV 444 video signal, the YUV 444 video signal is downsampled to a YUV 422 video signal.
