Abstract: Embodiments of the present invention generally provide m Methods and apparatus for reducing power consumption of backlit displays are described. Power consumption is reduced by dimming backlighting by a first scale factor and boosting pixel values by a second scale factor to compensate for the dimming. The scale factors may be constant values.

A graphical processing system is described including an integrated circuit capable of transforming a pixel value from a gamma-compensated space to a linear space.

Abstract: A method and system for combining a set of n still image frames into a single reduced noise still image. The invention reduces visible noise, along with some television color artifacts, in still images captured from a video stream by combining data from multiple video frames. Each frame comprises an XY array of picture element (pixel) data. In the preferred embodiment, each pixel includes data defining an intensity level as well as color values. A weighted average of several frames of video is taken to generate a single still output frame. The weighting is determined adaptively in order to reduce inter-frame motion artifacts. The resulting output has substantially less visible noise than a simple unweighted average. The algorithm is much faster and simpler to implement than true multi-pixel motion estimation, which is not really necessary in a series of nominally-still images.

Abstract: An electronic endoscope system which picks up images by colors sequentially in a field sequential method, simultaneously converts the field sequential image signals obtained thereby, and reproduces the images as color images. The electronic endoscope system sample checks at every given cycle whether an image being currently picked up is a still picture image or a moving picture image. In the electronic endoscope system, the field sequential image signals are simultaneously. Each time the currently picked-up image is found as a still image, the storage contents of the memory means are updated to the latest field sequential image signals. Due to this, the memories can always store the latest field sequential image signals with no color discrepancies, e.g. shift. If a freeze instruction is input, then the updating of the storage content of the memories is immediately inhibited, so that the latest still image signals having no color discrepancies can be obtained from the memories.
