发明名称 PICTURE PROCESSING UNIT
摘要 PURPOSE:To obtain a picture subject to desired processing by providing a control means and a discrimination means which sets a content of color and processing and compares and discriminates the color recognized with a recognition means with the color set by a setting means to the processing unit. CONSTITUTION:An 8-bit picture data is outputted from a CCD read section 301 and inputted to a shading correction section 302. A shading correction section 302 detects and corrects a shading quantity of a light source and a lens. A picture signal subject to the processing is stored tentatively in a shift memory section 303. A color recognition section 304 recognizes and detects the color. The detected color discrimination signal and picture data are inputted to a color processing section 307, an operation section 310 applies the registered processing to the picture data and outputs the result and a color processing signal to a synthesis processing section 305. Moreover, the picture data outputted from the memory section 303 is similarly outputted to the processing section 305. The processing section 305 decides which of two picture signals is to be selected according to the command of the color processing signal, applies optimum density processing to the decided picture signal when it is reproduced and outputs the result to a trimming processing section 306.
