    摘要: There is a signal processing apparatus, including a gamma correction circuit that performs gamma correction on an input luminance signal and generates an output luminance signal, an output-to-input ratio calculation circuit that calculates a ratio of the output luminance signal to the input luminance signal as an output-to-input ratio of a luminance signal, and a color difference correction circuit that multiplies an input color difference signal by the output-to-input ratio of the luminance signal and generates an output color difference signal. As a result, by correcting the input color difference signal using the output-to-input ratio of the luminance signal, the output color difference signal in which color difference correction has been performed in view of influence of gamma correction can be generated.

    摘要: An image processing apparatus includes: input means for inputting a video signal; decoding means for decoding the video signal; filtering means for performing predetermined filtering on the decoded video signal; and control means for calculating an average bit rate by dividing an amount of bits generated per predetermined data unit from the decoded video signal, and controlling a characteristic of the filtering in accordance with the average bit rate. When the video signal is input per image file, the control means calculates the average bit rate by dividing a file size of the image file by a playback time corresponding to the file size, and when the video signal input is sequentially input per picture, the control means calculates the average bit rate by dividing a sum of generated bits per picture for a predetermined number of frames by the predetermined number of frames and the frame rate.
