Abstract: Visual safety is ensured when image switching takes place. When an image is switched by nonlinear reproduction, a display property is kept switched, during a transition display period, to a transition display property with a brightness level kept lower than a normal level, on the basis of pixel statistical information regarding the image. For example, an electro-optic conversion property is controlled to a transition property or the brightness level of a backlight is suppressed.

Abstract: Methods and systems to adjust differently brightness and contrast for dark and bright pictures on a display are provided. Given a tone-mapping curve mapping an input dynamic range to a display comprising a minimum and maximum display luminance value, the maximum display luminance value is lowered to an adjusted luminance value according to user defined parameters. The input dynamic range is tone-mapped to the display dynamic range using the adjusted luminance value. For brightness control, the tone mapped image is stretched linearly back to the maximum display luminance value. For contrast control, a gamma or power EOTF of the display is adjusted according to the adjusted luminance. For displays with global backlight control, the global backlight is adjusted only when contrast is adjusted.

Abstract: A method for processing a static pattern in an image and a circuit system are provided. In the method, each of frames of a video is divided into multiple areas. Several algorithms are used to calculate a static pattern index of every area. The static pattern index is used as a reference for determining if the area covers part or entire of a static pattern. An index threshold can be used to check the areas that are determined as the static pattern initially. A time threshold is then used to confirm the areas with the static pattern in every frame. Image data of the areas which are determined as the static patterns can then be adjusted, such as having brightness of the area that is determined as part or entire of the static patterns decreased, for preventing the display panel from negative effects of the static pattern.
