Abstract: There are provided systems and methods for tinting an image by monochromatic tinting using saturation maps for use by an application providing a user interface supporting customizable tinted images. By using saturation map and a monochromatic value map derived from the image and configuring the saturation map to specify areas for tinting, a tint color can be applied to the image by a series of quickly processed arithmetic calculations. This provides a lightweight and high quality method for tinting images within an application without wasting unnecessary network bandwidth or processor resources. Furthermore, the method can be adapted to apply multiple tint colors for multiple tints or use an alpha channel to restore color information lost due to the monochromatic value map. The resulting tinted image can also be used as a texture for a three-dimensional rendering engine.

Abstract: Correction data tables or look up tables (LUTs) are stored in a table memory. When an overshoot calculation section switches an active LUT, the overshoot calculation section obtains the new active LUT not out of an external memory but out of the table memory. A table managing section deletes, from the internal memory, LUTs to which the new active LUT does not switch over directly, for example non-adjacent LUTs, meanwhile the table managing section obtains a new adjacent LUT from the external memory so as to store the new adjacent LUT in the table memory. With the arrangement, it becomes possible for a drive circuit to (i) operate at the same processing speed as a drive circuit in which all tables are stored in the internal memory, and simultaneously, (ii) reduce the amount of memory.

The GPU may compensate an individual pixel's color channel value based on a corresponding previous color channel value in order to minimize crosstalk between neighboring color fields.

Abstract: The video output system in a computer system reads pixel information from a frame buffer to generate a video output signal. However, the video output system must often compete with other memory users in order to access a frame buffer in a shared memory system. When memory bandwidth resources are limited, the performance of a computer system will suffer. To reduce the performance drop, a dynamic color mode switching system has been introduced. The dynamic color mode switching system detects when memory bandwidth resources are limited and then instructs the video output system to switch to a color mode that reduces the amount of reads from the memory system without any user intervention.

The profile generation module generates the calorimetric color appearance profile based on the user input, and generates the calorimetric color device profile based on the user input and the spectral data. In this way, calorimetric color profiles are generated as needed, and spectral data can be used with calorimetrically based color management systems.
