An integrated circuit includes display processing components to process pixel data of digital video. The integrated circuit also includes mask-programmable logic integrated with one or more of the display processing components to receive the pixel data in a first color space and at least a second color space, where the mask-programmable logic can further process the pixel data to enhance the digital video.

Integrated circuit to process data in multiple color spaces

A display processor integrated circuit includes a display processor portion and an on-chip programmable logic portion. The programmable logic portion can be configured to implement custom video and/or image enhancement functions. The display processor portion performs block-based motion detection. If no motion is detected for a given block of pixels, then interline gaps in the block are filled using temporal interpolation. If motion is detected, then interline gaps are filled using spatial interpolation. To maintain accuracy without unduly increasing computational complexity, a less complex high angle spatial interpolation method is employed where a low angle tilt condition is not detected. A more computationally intensive low angle spatial interpolation method can therefore be employed in low angle tilt conditions. Integrated circuit cost is reduced by employing pipelining to write parts of segment buffers at the same time that other parts are being read to perform the interpolation process.

Deinterlacer using low angle or high angle spatial interpolation

An integrated circuit has a substantially non-customizable hardware portion and a mask-programmable logic portion. An image processing function common to many different makes and models of a type of electronic consumer device (for example, an image display device) is performed by the substantially non-customizable hardware portion. The substantially non-customizable hardware portion also outputs pixel data in both a first color space format and a second color space format. The mask-programmble logic portion can be mask-programmed for an individual manufacturer of electronic consumer devices such that the mask-programmable logic portion performs an additional special function specific to the electronic consumer devices of the individual manufacturer. Certain functions are better or more easily performed on pixel data in one color space format than another. Pixel data is therefore supplied to the mask-programmable hardware portion in multiple different color space formats, or in a selectable one of multiple different color space formats.
