摘要： An encoding apparatus which structures a band-divided digital image signal into three-dimensional blocks each having a plurality of pixels, discriminates each three-dimensional block between a moving image block and a static image block, and, in the case of a static image block, encodes only the three-dimensional blocks in the lower frequency bands while dropping the three-dimensional blocks in the higher frequency bands. However, of moving image blocks, blocks having a large pixel variance value are encoded as effective image blocks. Also, different size weightings are performed to transform coefficients depending on whether the block is discriminated as a moving image block or a static image block. Furthermore, shuffling is performed on a group of moving image blocks and a group of static image blocks independently of each other, and the transform coefficients for the static image blocks are quantized after quantizing all transform coefficients for the moving image blocks.

摘要： A multi-screen display apparatus is a multi-screen display apparatus in which screens of a master apparatus and slave apparatuses are arranged. Each of the master apparatus and the slave apparatuses includes a light source for three primary colors formed of a semiconductor light emitting element, and a memory circuit for storing a brightness corresponding to a control current that is specific to each of the primary colors of the light source. The master apparatus determines a common target brightness based on the brightness outputtable by the master apparatus itself and the brightnesses outputtable by other apparatuses. Each of the master apparatus and the slave apparatuses reads, as a target control current, the control current corresponding to the target brightness from the memory circuit, and supplies the target control current to the light source.

摘要： When a digital video signal is compressed, the amount of resulting data is predicted and the quantization level is controlled so as to obtain a constant bit rate. The prediction is made by computing a linear combination of a standard deviation and a number of non-zero coefficients, or by computing a sum of absolute differences between adjacent pixel values, or by computing a dynamic range of pixel values. The bit rate can also be controlled by deleting high-frequency coefficients. To avoid image degradation, the quantization level can also be controlled according to the sensitivity of small image areas to quantization noise. Sensitivity is determined by dividing an area into subblocks, which may overlap, and calculating statistics in each subblock. To reduce the amount of computation required in motion estimation, chrominance motion vectors are derived from luminance motion vectors.
