Abstract: Systems, apparatuses and methods may a performance-enhanced computing system comprising a sensor for measuring luminance values corresponding to light focused onto the sensor at a plurality of pixel locations, a memory including a set of instructions, and a processor. The processor executes a set of instructions causing the system to generate a multi-segment tone mapping curve, generate a set of tone mapping values corresponding to the multi-segment tone mapping curve for equally spaced input values between zero and one for storage into a look up table, and process the luminance values using the look up table to apply the tone mapping curve to the luminance values of the pixels.

Abstract: An apparatus to facilitate regulating a display panel backlight is disclosed. The apparatus comprises one or more processors to receive a first image frame, generate a first correction lookup table associated with the first image frame, apply a filter to the first correction lookup table to generate a first smoothened lookup table and transform the first image frame using the first smoothened lookup table to generate a pixel boosted frame and a memory communicatively coupled to the one or more processors.

Abstract: Methods and apparatus relating to techniques to provide dynamic pixel density adjustment for display panels not driven by backlight are described. In an embodiment, logic causes a first plurality of pixels of a display panel to be turned off in response to an indication that a charge level of a power supply, coupled to supply electrical power to the display panel, has dropped below a threshold level. The display panel is not backlight drive (such as an OLED or QDOT display panels. Other embodiments are also disclosed and claimed.

Abstract: If the picture complexity is low then the number of pixels in a frame may be reduced. For example, pixel-to-pixel variation in terms of RGB color values can be used to determine the complexity of the frame. Frames can be characterized, in one embodiment, as non-complex frames with less pixel variation and complex frames with very high pixel variation. The high PPI may be used only for complex frames while non-complex frames can use low PPI. This method reduces memory fetching and pixel processing within the display engine and thereby saves power.

Abstract: Systems, apparatus, articles of manufacture, and methods are disclosed for gradient image detection to improve power savings. An example disclosed apparatus includes programmable circuitry to at least one of instantiate or execute the machine readable instructions to identify a region in an image that satisfies a brightness threshold, define a plurality of lines in the image that extend away from the region, and determine the region corresponds to a gradient based on an analysis of pixels along different ones of the plurality of lines.

Abstract: A number of frames may be transferred in one frame period to a display panel followed by at least one frame period during which no frame is transferred. During this link idle time, the display panel continues to work on the transferred frames. However, the link and/or graphics processor may be powered down during this time to reduce power consumption.

Abstract: By converting a first color space to a second color space, using a two-dimensional lookup table in said second color space, and converting from said second color space to said first color space, it may be possible to use one or more two-dimensional lookup tables (LUTs) to do a task conventionally handled by three-dimensional lookup tables. This may reduce storage requirements and memory bandwidth requirements in some embodiments. In general a color pixel with N color components can be processed with n number of M dimensional LUT where M
