摘要： An edge direction determination method for a pixel of a display picture. The display picture has a corresponding edge map. The pixel has corresponding pixel direction pairs. First, in step (a), it is judged whether the pixel is an edge pixel according to the edge map. Next, in step (b), it is judged whether the pixel has a right-inclined edge direction or a left-inclined edge direction when the pixel is the edge pixel. Then, in step (c), the edge direction of the pixel is determined according to specific pixel direction pairs corresponding to the same inclined edge direction if a judged result in step (b) is affirmative. Finally, in step (d), if the judged result in step (b) is negative, it is judged whether the pixel has a horizontal edge direction or a vertical edge direction.

摘要： The invention relates to a 2D YC separation device and YC separation system for separating a composite signal into a luma signal (Y) and a chroma signal (C). Firstly, the 2D YC separation device utilizes a low-pass filter to separate the composite signal into a low-frequency composite signal and a high-frequency composite signal. The low-frequency composite signal is a low-frequency luma signal. A 2D comb filter is utilized to separate the high-frequency composite signal into a high-frequency luma signal and the chroma signal. The luma signal is equal to the low-frequency luma signal plus the high-frequency luma signal. Therefore, the 2D YC separation device of the present invention can perfectly separate the composite signal so as to obtain a better luma signal and chroma signal. The YC separation system of the present invention further comprises a 3D YC separation device and a motion detection device, so as to obtain a precise luma signal and chroma signal.

摘要： An encoding method to encode image data comprising a sequence of blocks with a predetermined compression rate in one pass is disclosed. The blocks are divided into two sets, a first set and a second set. The blocks in the first set are encoded within the sum of an available bit length and a predetermined lending bit length. The blocks are encoded in the second set within the available bit length. A lending bit length is updated when the current bit length is larger than the available bit length. The left bit length is updated when the current bit length is not larger than the available bit length. The left bit length and the lending bit length are adjusted when the current block is in the second set, the lending bit length is positive and the left bit length is larger than a predetermined threshold.
