Abstract: The invention provides for calculating the sum of the luminance values of all pixels in each of a number of regions making up the whole image. A histogram is then created of all the sums of luminance at the end of each frame. The histogram is then rescaled such that the luminance range is normalized. Once the histogram has been created, an appropriate transfer function is created using the integrated luminance histogram for the frame. In this way detail within significant objects in the image are enhanced since the average luminance of objects in an image are weighted more than then the luminance of individual pixels providing a more realistic transfer function.

Abstract: A clock recovery circuit in a digital display unit for recovering a time reference signal associated with analog display data. The clock recovery circuit includes a phase-locked loop (PLL) implemented in digital domain and an analog filter to eliminate any undesirable frequencies from the output signal of the PLL. The PLL includes independent control loops to track long term frequency drifts of the time reference signal and the transient phase differences respectively. By providing such independent control loops, the generated clock can be better synchronized with the time reference signal.

Abstract: An extended overdrive table uses the saturation regions to store useful data that conformably extends the unsaturated region in a natural way. This extended overdrive table reduces the size of any interpolation errors when straddling crossover points to acceptable levels without requiring storing or using any crossover data. In addition, since the saturation regions are used to hold the new data, no additional storage requirements are introduced. The numeric range of the extended table is increased and it is therefore supposed that the bit depth of the table entries is increased, but the table can be resealed to retain the original bit depth with insignificant loss of accuracy. Also, the new data incorporated into the saturation regions allows run time calculation of the pixel attained at the end of the frame time that is needed as the start of the pixel for the next cycle.

Abstract: Global-adaptive deinterlacing systems and methods for reducing scintillation and feathering artifacts. Motion adaptive deinterlacing (MADI) local motion quantization thresholds are adaptively adjusted according to the amount of global motion present in the video sequence, thereby minimizing scintillation and feathering artifacts when deinterlacing the fields. A set of global motion scenarios are defined for the purpose of classifying fields, and a number of global motion indicators are used to detect on a field-by-field basis different global motion scenarios. The global motion indicators are corrected to reduce Luma dependencies, thereby improving reliability and robustness. Depending on the global motion scenario of a field, the local motion thresholds are adaptively adjusted. The adaptive adjustment of quantization thresholds are optionally also applied to temporal noise reduction and cross-color suppression.
