Abstract
An image coding system includes an optical system , an image pick-up unit , a color space/pixel number converting unit , an orthogonal converting unit , a quantizing unit , a variable run length coding unit and a storing/transmitting unit . The system further includes a code volume control unit for providing, in a first coding process, image data obtained from the color space/pixel number converting unit as a result of omission of at least the color space conversion, among the color space and pixel number conversions, to the orthogonal conversion unit , and computing quantizing coefficient data adequate for obtaining a target code volume from the code volume of coded data provided from the orthogonal converting unit and the target code volume. In a second coding process, the color space/pixel number converting unit executes both of the color space and pixel number conversions and provides resultant image data to the orthogonal converting unit or storage and/or transmission of coded data provided as a result from the orthogonal converting unit
