Abstract: A four-time resolution refinement of 3D-dither algorithm is provided in this present invention. A 4×2 pixel-block is treated as an observed unit in this present invention, which includes two 2×2 pixel-blocks. In order to eliminate moving lines and dithered edges, the two least significant bits (LSBs) of the pixels are treated depending on cases. For the first 2×2 pixel-block, when 2-bit LSBs being 01 and 11, the pixel being assigned a carry is an upper-left, lower-right, lower-left, and upper-right sequence in a 2×2 pixel-block for four sequential frames. For the second 2×2 pixel-block, when 2-bit LSBs being 01 and 11, the pixel being assigned a carry is a lower-left, upper-right, upper-left, and lower-right sequence in a 2×2 pixel-block for four sequential frames. For both 2×2 pixel blocks, no pixel is treated for 2-bit LSBs being 00. For 2-bit LSBs being 10, the pixel row of the 4×2 block switches between the upper and the lower row for every frame.

The first electrodes are driven to set display data for a selected one of the cell lines. The display also has a sequence setting unit for setting sequences of scanning the second electrodes, and a sequence selection unit for selecting one of the sequences that minimizes the current and power consumption of a first-electrode driver without deteriorating the quality of the displayed images.

Abstract: Flash frames are detected in video streams, for example, by looking for short sequences of one or more frames (or, to be more general, pictures) in which the frames within the sequence are not well-correlated to the frames that immediately precede and follow the flash sequence, where those frames before and after the flash sequence are themselves well-correlated to each other. Video compression processing is then adjusted in some way to handle flash frames in a special manner. For example, since flash frames are poorly correlated to their neighboring frames, it would be best not to make predictions based on such flash frames when encoding other frames. Encoding flash frames as anchor frames (e.g., I or P frames in an MPEG encoder) would be detrimental to those frames that are predicted from the anchor frames. Rather, flash frames are preferably encoded as frames that are never used as references for coding other non-flash frames (e.g., as B frames in an MPEG encoder).

In another embodiment, the scene change and 3:2 pull-down detection component, and the second phase of the motion estimation occur after the first phase of motion estimation.

Display frames are selected from the sequence of the intermediate frames, and as the case may be, also from the source frames.
