<P>PROBLEM TO BE SOLVED: To compute parameters for image adjustment on the basis of past adjustment values, corresponding to the image features or an external environment. <P>SOLUTION: A feature amount quantizing section 61 accepts an image features, environmental information or information about the contents, and quantizes them. A weight-calculating section 62 calculates a weight d, on the basis of a volume operation state by a user. A weight total number memory 63 stores weight total numbers Dv, extracts a weight total number corresponding to the features v and outputs it, and calculates a new weight total number Dv, using the value of the weight d and updates it. A volume generating section 64 stores past output volume values S'v and Z'v, calculates and stores output volume values Sv, Zv corresponding to the features v on the basis of parameters S, V being the final adjustment values, the features v, the weight d and the weight total number Dv, and outputs the volume values Sv, Zv to a coefficient generating section, according to the control of a system controller 12. This apparatus is applicable to a television receiver. <P>COPYRIGHT: (C)2004,JPO |
