In the early firmware releases, the gamma/grayscale tool offered only RGB adjustments.This may sound like an obscure and unimportant technical distinction, but for the user it means that gamma/grayscale adjustments are now much smoother and more predictable. Finally, gamma is reapplied for output to the display. This means that a gamma-weighted source signal comes into the unit, the processor then applies a de gamma function to this, which puts the signal into a linear color space. Anchor Bay has since re-engineered this tool so that it operates in linear color space. ![]() This made getting accurate white balance adjustments very tricky. You could adjust the RGB controls at a particular level of stimulus several ticks and nothing seemed to change, until all of a sudden a very large measured change in the white balance would appear. The result of this was that user adjustments had noticeably non-linear effects. An early version of 11-point gamma/grayscale adjustment tool operated in a gamma-weighted color space.With this latest update, the calibration capabilities of this truly revolutionary product have been enhanced substantially. #Video processor gamma control update#The original update was promising, offering the aforementioned gamma/grayscale adjustment tool and a more limited version of the CMS. ![]() #Video processor gamma control series#The development of the Duo's calibration features has been incremental, appearing feature by feature in a series of firmware updates over the last few months. Those calibration controls include an 11-point gamma/grayscale adjustment and a full-featured color management system (CMS) that allows the user to independently adjust the saturation, hue, and brightness of the primary colors and secondary colors. #Video processor gamma control plus#At an MSRP of $1299 and street prices below $1000, this is a surprisingly affordable option for those looking for world-class video processing, transcoding, and switching (it offers eight 1.3 HDMI inputs and 2 HDMI outputs, plus a host of analog inputs) and custom calibration controls. This update provides it with exceptionally powerful video calibration capabilities. Sony cannot assume responsibility for any problems arising out of the use of these circuits.Accupel HDG-4000 Video Test Pattern GeneratorĪnchor Bay has recently finished development on a major update to their popular DVDO iScan Duo external video processor. Application circuits shown, if any, are typical examples illustrating the operation of the devices. #Video processor gamma control license#This information does not convey any license by any implication or otherwise under any patents or other right. ♦ No need external DRAM Silicon gate CMOS IC Sony reserves the right to change products and specifications without prior notice.

It is not needed to largely reconstruct existing system software. The connection to a customer system is easy and also the picture adjustment is easy by small registers. Those functions can adjust a picture depending on user's liking or characteristics of various panels. And two sets of 12-bit RGB independent gamma compensation can change the gamma curve and white balance. The function "Two Dimensions Sharpness" improves sharpness and spacial effect. This function is realized only by signal processing, and it does not depend on back-light system. Especially a contrast for the dark scene is improved. The function "intelligent Contrast Synthesizer" improves the contrast feelings and resolution feeling. The method of color adjustment is easier and the operability is improved compared to the general Hue adjustment. This LSI has some unique features the function "Bi-axial Color Control" that improves a quality of color representation by changing colors on x-y chromaticity graph. Intelligent Panel Controller for Standard Frame Rate System The CXD4728R is an image signal processor for Fiat Panel Display system, which can improve a quality of color representation, contrast feeling, and resolution feeling. ![]()
