Abstract
An image processing apparatus includes: a quantization parameter determination section which determines a reference quantization parameter; a back search section which detects a detected quantization parameter for each coding unit; a coding section which codes the input image for each coding unit; a feedback control section which confirms the generated code quantity of the input image, and if it is predicted that the generated code quantity for each image unit exceeds the target code quantity for each image unit, increases the determined reference quantization parameter; and a coding control section which performs control such that, during dubbing, the coding section uses the reference quantization parameter when the back search detection is not successful and selectively uses the reference quantization parameter or the detected quantization parameter in accordance with a determination result of a need for code quantity suppression when the back search detection is successful.
