Patent ID: 8160131

Claim:
An image processing apparatus, comprising: a decoding unit configured to decode coded image data into image data; a filtering unit configured to filter the image data by using a first noise filter by digital processing; an analog-image output unit configured to convert the image data into analog signals and output the analog signals in an analog manner; a digital-image output unit configured to output the image data in a digital manner; an output determination unit configured to select the analog-image output unit or the digital-image output unit for outputting the image data to an external device; and a filter control unit configured to switch a characteristic of the first noise filter used in the filtering unit in accordance with the selection made by the output determination unit, wherein the analog-image output unit includes a second noise filter to filter the analog signals by analog processing, and the filter control unit controls the characteristic of the first noise filter so that a passband of the image data which have been filtered by the first noise filter, to be output from the digital-image output unit, and a passband of the analog signals which have been filtered by the first noise filter and the second noise filter respectively, to be output from the analog-image output unit, become substantially equal.
