Abstract
A system (14') for processing pixel video data having a selectable number of bits is provided. The system (14') comprises first, second and third video processors (20), (22) and (24). The first video processor (20) receives and processes pixel data of a luminance video signal. The second video processor (22) may receive and process pixel data of a chrominance video signal and may generate one of first, second and third video signal outputs. The third video processor (24) may process the chrominance video signal and may also generate at least two of the output video signals.
Claims19
A system for processing pixel data, each pixel having a selectable number of bits, said system comprising:
- a first video processor for receiving and processing pixel data, wherein said pixel data is of a selectable number of bits, said number being dependent upon the dynamic range of said system, of a first input video signal, generating an output video signal;
- a second video processor responsive to the output video signal of said first video processor and a second input video signal, said second video processor operable to process pixel data of said second input video signal and operable to generate one of a first, second and third output video signals;
- and
- a third video processor responsive to at least one of said first and second video processors, said third video processor operable to process said second input video signal and operable to generate at least two of said first, second and third output video signals.
A method for processing pixel data, said method comprising the steps of:
- loading appropriate functions into a first, second and third video processor depending upon the number of bits selected for each pixel of data;
- processing pixel data of a first input video signal in the first video processor and sending said processing pixel data to at least one of the second and third video processors;
- processing pixel data of a second input video signal in at least one of the second and third video processors;
- generating first, second and third video signal outputs using a color space conversion function in at least one of the second and third video processors.
A display system that receives video input for display on a spatial light modulator, comprising:
- an analog to digital converter for converting an input video signal to pixel data, each pixel having a selectable number of bits;
- a separator circuit for separating said input video signal into first and second input video signals;
- a first video processor responsive to said separator circuit for receiving and processing pixel data of said first input video signal generating an output video signal;
- a second video processor responsive to the output video signal of said first video processor and said separator circuit, said second video processor operable to process pixel data of said second input video signal and operable to generate one of a first, second and third output video signals;
- a third video processor responsive to at least one of said first and second video processors, said third video processor operable to process said second input video signal and operable to generate at least two of said first, second and third output video signals;
- a display memory responsive to at least one of said second and third video processors for receiving said first, second and third video signal outputs of pixel data and for formatting said pixel data into pit-planes of data;
- and
- a spatial light modulator for receiving said bit-planes of data and for providing an image corresponding to said bit-planes of data.
