IMAGE PROCESSING DEVICE AND METHOD |
摘要 |
Disclosed are an image processing device and method for noise reduction adapted to the image and bit rate. A low pass filter setting unit (93) sets a filter coefficient corresponding to intra-prediction mode information and a quantization parameter selected from filter coefficients stored in an internal filter coefficient memory (94). A neighboring pixel setting unit (81) uses the filter coefficient set by the low pass filter setting unit (93) to perform filter processing of neighboring pixel values in a target block from frame memory (72). A prediction image generating unit (82) generates a prediction image by intra-prediction using the filter-processed neighboring pixel values from the neighboring pixel setting unit (81). The method may be applied, for example, to an image encoding device that encodes using the standard H.264/AVC. |
