摘要:
The present invention relates to an image processing apparatus that performs predetermined conversion processing with keeping the color of an original image and eliminating processing time necessary for color space conversion, when applying special effects on video signals. The image processing apparatus includes a video signal input section for receiving a video signal having a value represented in a first color space, a signal converting section for performing predetermined conversion processing on a signal having a value represented in a second color space that is different from the first color space, and a signal interface section for supplying the signal converting section with the video signal, received by the video signal input section, that has a value represented in the first color space as a substitute for the signal having a value represented in the second color space.
