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: Some embodiments described herein provide a method for providing brightness control of a display. An image including a first pixel associated with a first color and a second pixel associated with a second color may be obtained for display. A first brightness control mapping may be designed for the first color and a second brightness control mapping may be designed for the second color. Linear interpolation between the first brightness control mapping and the second brightness control mapping may be applied for a third pixel within the image having a third color different from the first color and the second color. The first, second and third brightness control mapping may then be applied to the first, second and third pixels, respectively. An output image including the first pixel, the second pixel and the third pixel may be displayed after the applying.

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: Systems and methods for generating a detail-enhanced video signal are provided. In a method for generating the detail-enhanced video signal, an input video signal is received. A first signal that is a linear transformation of the input video signal is generated. A detail signal is generated by determining a difference between the input video signal and the first signal, where the detail signal includes information that is added to the input video signal to generate the detail-enhanced video signal. A filtered detail signal is generated by removing noise from the detail signal. The filtered detail signal is multiplied by a gain function to generate a second signal. The gain function is based on an amount of variance in the input video signal. The input video signal and the second signal are combined to generate the detail-enhanced video signal.

Abstract: Systems and methods are provided for upscaling a digital image. A digital image to be upscaled is accessed, where the digital image comprises a plurality of pixel values. A first half pixel value is computed for a first point in the digital image based on a plurality of pixel values of the digital image surrounding the first point and an activity level. A second half pixel value is computed for a second point in the digital image, and an interpolated pixel of an upscaled version of the digital image is determined using a plurality of the pixel values, the first half pixel value, and the second half pixel value.
