摘要： 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.

摘要： An image processing apparatus prevents the inappropriate application of error diffusion and adaptively applies palette conversion functions according to the properties of the source. A processing subsystem performs various processing with respect to an original video source. A palette converter converts the palette bit depth, having modifiable palette conversion functions for creating the illusion of expressing the pre-conversion palette tones in the post-conversion image. A controller turns on the palette converter, turns off the palette converter, or modifies the palette conversion functions thereof, in accordance with at least original source information and system-wide settings information.
