    Abstract: When image reduction is effected at the writing of the image to a frame memory, a first image portion which is to be dropped by the reduction is subjected to weighted-averaging with a second image portion adjacent thereto to modify the second image portion. When an image read from the frame memory is enlarged, a first image portion which is to be added by the enlargement is generated by weighted-averaging two second image portions located before and after the first image portion. When an image is enlarged, it is enlarged by a first enlargement factor in the range of 1 to 2 and enlarged by a second enlargement factor that is an integer, thereby obtaining a result image enlarged by a third enlargement factor that is the product of the first and second enlargement factors.

    Abstract: The present invention realizes high-speed transfer of video data into a video memory. Addresses used in DMA transfer operation are calculated by simple arithmetic operation in a DMA address operation unit of a DMA controller. Video data are transferred according to the addresses at a high speed to an arbitrary position in a VRAM. An FIFO memory unit can expand and reduce a video image by desirable magnifications in both vertical and horizontal directions during DMA transfer of video data.

    Abstract: A reference value memory circuit 552 in a video switch control circuit 550 stores upper threshold values DU and lower threshold values DL of respective colors defining a predetermined range of chromaticity. A color comparator circuit 554 compares these upper threshold values DU and the lower threshold values DL with a second video signal LSMEM. When a color represented by the second video signal is within the predetermined range of chromaticity, a color comparison signal S1, which is an output of the color comparator circuit 554, becomes at H level, while the color comparison signal S1 becomes at L level when the color is out of the predetermined range of chromaticity. A selection signal S2 is generated according to the color comparison signal S1 and a switcher signal CNT. A video switch 510 selects one of a first video signal LSPC output from a computer and a second video signal LSDA output from a video memory 310 in response to the selection signal S2. As a result, only a desirable portion of the second video image is superimposed over the first video image.

    Abstract: A video multiplexing system for superimposition of scalable video data streams upon a background data stream has a video decoder to extract a first luminance signal, an A/D converter to convert the first luminance signal to digital form, a three-port video memory for storing the digitized luminance signal, a D/A converter for receiving the stored digitized luminance signal and converting it to analog form, a mixing, or multiplexing means, having one input coupled to the D/A converter output, at least one other luminance signal source as an input and control inputs for directing the selection of one of the input luminance signals as an output, and a control means such as a microprocessor for controlling the various components. The write operations to the video memory are synchronized to the incoming luminance signal, and the read operations from video memory are synchronized to the display device. This video multiplexing architecture provides the ability to open a viewport of arbitrary size at any position within a larger display. Scaling of the digitized luminance signal to fit an a viewport of arbitrary size is achieved by varying the frequency of the A/D converter clocks so as to expand or shrink the resulting image.
