Abstract
A mosaic picture processing apparatus and method is disclosed. The present invention includes a memory device for storing picture data, which include index data, pattern data, and pattern control data. A pattern coordinate generating device is used for generating a horizontal coordinate and a vertical coordinate. A mosaic device is used for generating a mosaic control signal. Next, the index data is read from the memory device in response to the horizontal coordinate, the vertical coordinate, and the mosaic control signal. Further, the pattern data is read from the memory device in response to the horizontal coordinate, the vertical coordinate, the index data, and the mosaic control signal.
Claims24
A mosaic multi-layer picture processing apparatus, comprising:
- memory means for storing a plurality of index data, a plurality of pattern data and a plurality of pattern control data;
- timing generating means for generating a plurality of timing signals for each of a plurality of layers;
- processing means responsive to said plurality of timing signals for reading the index data and reading the pattern data, said timing signals controlling a reading sequence of the index data and the pattern data depending on a number of said layers;
- means for generating a plurality of mosaic control signals to control said processing means;
- and
- priority control means responsive to a priority signal and a transparency signal for selecting one layer of said processing means.
A mosaic multi-layer picture processing apparatus, comprising:
- memory means for storing a plurality of index data, a plurality of pattern data and a plurality of pattern control data;
- timing generating means for generating a plurality of timing signals for each of a plurality of layers;
- processing means responsive to said plurality of timing signals for reading the index data and reading the pattern data, said timing signals controlling a reading sequence of the index data and the pattern data to read the index data for one time and the pattern data for at least one time to achieve a full usage of a processing bandwidth;
- means for generating a plurality of mosaic control signals to control said processing means;
- and
- priority control means responsive to a priority signal and a transparency signal for selecting one layer of said processing means.
