IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD |
摘要 |
The present invention can realize an image processing device and an image processing method that enable a simplified circuit configuration. An image encoding device (200) encodes an input image (91) in an ordinary process that is the same as main encoding on the basis of a predictive quantization parameter (QPd), while encoding the input image (91) in a simple manner (simplified process) on the basis of the predictive quantization parameter (QPd) and quantization parameters (QP) approximate to the predictive quantization parameter (QPd). The image encoding device (200) calculates a code quantity ratio R_reduction between a high-precision generated code quantity obtained through an ordinary process based on the predictive quantization parameter (QPd) and a generated code quantity obtained through a simplified process based on the predictive quantization parameter (QPd). The image encoding device (200) calculates high-precision generated code quantities based on the quantization parameters (QP) approximate to the predictive quantization parameter (QPd) on the basis of the code quantity ratio R_reduction and generated code quantities obtained through a simplified process based on the quantization parameters (QP) approximate to the predictive quantization parameter (QPd).
