A display processing device includes a display device interface and a processing unit. The processing is configured to transition at least a first component of the display processing system into a low-power state in response to an active region of a first video frame of a plurality of video frames having completed. A second component of the display processing device is configured to maintain a temporal count value corresponding to a current frame line of the plurality of video frames, and further to generate a first signal in response to the temporal count value corresponding to a first trigger value. The first signal causes the at least first component to transition out of the low-power state.

Synchronized low-power video playback

A three-dimensional (3-D) look up table (LUT) can be accessed using an address decoder to identify a plurality of vertices in the 3-D LUT based on a number (m) of most significant bits (MSBs) of three coordinate values representative of a first color and a non-zero integer (p). The three coordinate values are determined by a source gamut. One or more memories store component values representative of a plurality of second colors determined by a destination gamut. The component values are stored at memory locations associated with the plurality of vertices. An interpolator maps the input color to an output color in the destination gamut based on the component values.

A recursive motion detector for detecting motion in an interlaced video signal. The motion detector includes a first frame motion detector receiving a next field and a first previous field, a second frame motion detector receiving a current field and a second previous field, and a third frame motion detector receiving a next field and a third previous field. Motion is detected when the first, second and third frame motion detectors combine to produce a frame motion result.

Recursive motion for motion detection deinterlacer

A recursive motion detector, comprises: a first frame motion detector receiving a next field and a first previous field; a second frame motion detector receiving a current field and a second previous field; and a third frame motion detector receiving a next field and a third previous field; wherein motion is detected when the first, second and third frame motion detectors combine to produce a frame motion result.

A method and apparatus for blending a video signal responsive to a chroma motion result is disclosed. The method and apparatus are configured to determine whether any chroma motion exists within the video signal and providing the chroma motion result, to provide a first blending signal based on the chroma motion result; to provide a second blending signal based on the chroma motion result; to modulate temporal filtered luma and chroma components of the video signal with the first blending signal, to modulate spatial filtered luma and chroma components of the video signal with the second blending signal, and to add the modulated temporal luma and chroma signals to the modulated spatial luma and chroma signals to provide a blended video signal.
