IMAGE PROCESSING APPARATUS THAT CAN PROVIDE IMAGE DATA OF HIGH QUALITY WITHOUT DETERIORATION IN PICTURE QUALITY.

摘要

DIGITAL IMAGE DATA OBTAINED BY A/D CONVERTING AN OUTPUT SIGNAL FROM AN IMAGE SENSING DEVICE (1) BY AN A/D CONVERSION CIRCUIT (3) IS CONVERTED INTO IMAGE DATA CORRESPONDING TO A PREDETERMINED IMAGE FORMAT BY A DIGITAL PROCESS OF AN IMAGE CONVERSION CIRCUIT (5). THEREFORE, AN IMAGE OF HIGHER QUALITY WITHOUT DETERIORATION IN THE PICTURE CAN BE PROVIDED IN COMPARISON WITH THE CASE WHERE DIGITAL IMAGE DATA OBTAINED BY A/D CONVERTING AN OUTPUT SIGNAL FROM AN IMAGE SENSING DEVICE IS FIRST CONVERTED INTO ANALOG VIDEO DATA AND THEN INTO A/D DATA. FURTHER FORMAT CONVERSATION CAN BE PERFORMED USING A SERIES OF CONTROLLABLE IMAGE CONVERTERS. THE IMAGE CONVERTERS AND A SIGNAL PROCESSING UNIT CAN BE SELECTIVELY PROGRAMMED TO PERFORM A VARIETY OF FORMAT CONVERSIONS AND IMAGE-TYPE SPECIFIC SIGNAL PROCESSING, RESPECTIVELY. PROGRAMMING CAN BE PERFORMED MANUALLY OR AUTOMATICALLY ACCORDING TO THE TYPE OF INPUT DEVICE OR THE TYPE OF INFORMATION IN THE IMAGE FIG. 46
