摘要： The present invention can realize better display of a dynamic image, and in addition, can make storage capacity of a memory smaller. A data conversion circuit 112 compares display data 102 of an n-th frame from the outside and display data 116 of the (n−1)-th frame stored in the memory 104, to generate a driving data signal 117 to deliver to a driver. Each time when a memory control circuit 103 reads display data q0, q5, q10, q15 corresponding to 20 pixels out of the display data 116 of the (n−1)-th frame, the memory control circuit 103 compresses display data d0–d19 of 20 pixels out of the display data 102 of the n-th frame from the outside to generated d0, d5, d10, d15, and stores the generated data into the same area where the display data q0, q5, q10, q15 of the display data of the (n−1)-th frame have been stored.

摘要： A random seed scramble for preventing the deterioration of a medium is applied to the next generation optical disk. A seed is stored to a BIS area. ID or an EDC is checked to hold interchangeability before and after scramble release. When no error is generated in data before the scramble release, it is recognized as an unscrambled disk. In contrast to this, when no error is generated in data after the scramble release, it is recognized as a scrambled disk. An information storing area showing an area to be rewritten by performing the scramble and an area to be rewritten without performing the scramble is arranged.

摘要： There is provided a liquid crystal display control device which can display pictures in a magnification mode by using only a memory having low-speed access and a low storage capacity. When a video signal has intermediate resolution or less, the enlargement processing is performed by a frame memory, a line memory and an enlargement processing control circuit. If the input operation and the output operation to and from the frame memory are synchronized with each other, it is sufficient for the frame memory to have a storage capacity of two lines. When the video signal has the same high resolution as a liquid crystal display panel, the video signal is output through a gate circuit to a display timing generating circuit, and it is displayed in a through mode. In this case, no processing is performed by the frame memory or the like.
