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.

A signal processing device configured to produce a first output video signal and a second output video signal as video signals for right and left eyes in a stereoscopic video, the first and second output video signals each having a predetermined number of output gradation steps, from a first input video signal and a second input video signal, the first and second input video signals each having a predetermined number of input gradation steps. A predetermined gradation value difference is produced between the gradation values of the first output video signal and the gradation values of the second output video signal to express a higher number of gradation steps than the number of output gradation steps in the stereoscopic video.

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.

An image processing apparatus includes: ΔΣ modulation means for applying ΔΣ modulation to an image; analog conversion means for converting a signal of the image, whose gradation is converted by the ΔΣ modulation means, into an analog signal; digital output means for outputting a digital signal of the image after gradation conversion; and analog output means for outputting an analog signal of the image after gradation conversion. The ΔΣ modulation means includes arithmetic means for filtering a quantization error; adding means for adding a pixel value of the image and output of the arithmetic means; quantization means for quantizing output of the adding means and outputting a quantized value; and subtracting means for calculating a difference between the output of the adding means and the quantized value. A filter coefficient for the filtering corresponding to the analog output is determined according to a frequency characteristic of the analog conversion means.
