DLP IntelliBright is a suite of TI image processing algorithms designed to improve the performance of LED-illuminated pico projection systems. The suite is composed of two distinct algorithms: Content Adaptive Illumination Control (CAIC) and Local Area Brightness Boost (LABB). DLP IntelliBright is a feature of DLPC343x-based chipsets.
The CAIC algorithm intelligently manages LED drive strength, on a frame by frame basis, resulting in optical image brightness and contrast. For example, if a frame has more blue than red or green, CAIC will increase the current to the blue LED. CAIC can be adjusted to maximize brightness, minimize power consumption (while maintaining the pre-CAIC brightness level), or somewhere in between with some brightness increase and some power savings.
The LABB algorithm intelligently boosts image brightness, on a frame by frame basis, resulting in brighter, more dynamic images. The LABB algorithm evaluates each image frame, in real time, first identifying dark areas of the image which can benefit from a boost in brightness, and then applying a brightness gain based on the configured “boost strength” setting. A relatively higher gain is applied to the darker regions of the image while little or no gain is applied to brighter regions of the image. LABB is particularly useful for pico projectors in high ambient lighting environments and can be automatically adjusted using an ambient light sensor.
