<p><P>PROBLEM TO BE SOLVED: To provide a moving image bit depth reduction apparatus and program, in which component signals of a moving image frame sequence having a prescribed bit depth are input sequentially and the depth of each bit of a luminance signal and/or a color difference signal in the component signals is reduced. <P>SOLUTION: A moving image bit depth reducing apparatus 1 includes a region-of-interest (ROI) extracting section 1a for extracting a region to be targeted, on the basis of sight characteristics specified beforehand as an ROI in a certain image frame; an ROI determining section 1b for determining an ROI from the ROI extracted in the image frame; and a signal-bit reducing section 9 for reducing the depth of each bit of a luminance signal and/or a color difference signal within the outside-ROI in the image frame, merely by the bits specified, respectively, so that the depth becomes lower than the prescribed bit depth. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
