Abstract: A system including a motion adaptive de-interlacer, a film mode detector, and a combiner. The motion adaptive de-interlacer is configured to determine a first output by de-interlacing a plurality of interlaced frames based on at least a first motion indicator indicating motion between fields of the plurality of interlaced frames. The film mode detector is configured to determine a second output based on a film mode detected based on at least a second motion indicator indicating motion between fields of the plurality of interlaced frames. The film mode detector is further configured to output a control signal based on the second motion indicator and the film mode. The combiner is configured to combine the first output and the second output based on the control signal.

Abstract: Apparatus, methods, and other embodiments associated with image processing operations are disclosed that provide image contrast enhancement. According to one embodiment, an apparatus includes histogram stretching logic to generate a stretched histogram. The stretched histogram is generated by compressing an enlarging a contrast of brightness bins of an equalized histogram of brightness component values formed from a previous input frame of image pixel data. Flat region detection logic classifies pixels of the previous input frame of image pixel data as being flat pixels or non-flat pixels, and counts a number of the flat pixels. Noise detection logic classifies the flat pixels as being noisy pixels or non-noisy pixels, and counts a number of the noisy pixels. The number of noisy pixels and characteristics of the stretched histogram are used to enhance the contrast of a current input frame of image pixel data.

Abstract: Aspects of the disclosure provide a method for reducing video latency. The method includes decoding compressed video data into video frames and storing the video frames in a frame buffer for subsequent display by a display interface, logging decoding ending times of video frames and display times of video frames to generate a latency history over a first window of time, and adjusting a display rate of the display interface based on the latency history over the first window of time in order to change waiting times of video frames, the waiting time of a video frame being a difference between the decoding ending time of the video frame and the display time of the video frame.

Abstract: System and methods are provided for modifying audio signals. A waveform representing an audio signal changing over time is received. A first time length is selected. A first starting point in the waveform is selected. A first pair of adjacent segments of the waveform are determined based at least in part on the first starting point and the first time length. The first pair of adjacent segments each correspond to the first time length. A first difference measure associated with the first pair of adjacent segments is calculated. In response to the first difference measure being smaller than a threshold, compression or expansion of the waveform is performed based at least in part on the first time length and the first starting point.
