A method of detecting an error of a multi-time programmable (MTP) operation in which each gamma-offset and each header-bit at predetermined reference gray-levels are written in a MTP memory device while the MTP operation is performed on a pixel circuit, the each header-bit indicating whether or not the each gamma-offset is written in the MTP memory device, and it is detected whether or not the MTP operation is performed on the pixel circuit based on a logical operation between the header-bits at the predetermined reference gray-levels read from the MTP memory device when the MTP operation is finished on the pixel circuit.

A method for controlling an electronic apparatus includes determining representative colors of pixels of a received image frame; calculating input dynamic ranges for respective representative colors based on brightness information of the received image frame; expanding a dynamic range for the representative colors based on at least one of the brightness information of the received image frame and display characteristics of the electronic apparatus; and outputting an image frame having adjusted brightness based on the expanded dynamic range.

The present disclosure generally relates to a method and device of converting a high-dynamic-range (HDR) version of a picture to a standard-dynamic-range (SDR) version of this picture. The method is characterized in that it converts the high-dynamic-range version to the standard-dynamic-range version of the picture according to: a first indicator (I1) that indicates the presence of color mapping parameters; a second indicator (I2) that indicates whether a device is configured to convert the high-dynamic-range version to the standard-dynamic-range version of the picture by taking into account said color mapping parameters; and a third indicator (I3) that indicates whether converting without taking into account said color mapping parameters is inhibited.

In an example method, one or more processing devices receive encoded image data, and cause visual content to be presented on a display device according to the encoded image data. Further, the one or more processing devices receive measurement data regarding the visual content presented on the display device, and determine, based on the measurement data, one or more first perceptual quantizer (PQ) codes corresponding to the visual content presented on the display device. Further, the one or more processing devices determine, based on the encoded image data, one or more second PQ codes, and determine one or more metrics indicative of a performance characteristic the display device based on the first PQ codes and the second PQ codes. The one or more processing devices store a data item including the one or more metrics.

One embodiment provides a method comprising determining a first representation of a source gamut of an input content in a first (2D) device-independent color space, determining a second representation of a target gamut of a display device in a second 2D device-independent color space, and determining a color transition protection zone (TPZ) based on the source gamut and the target gamut. The method further comprises utilizing a color gamut mapping (CGM) module to perform, based on the TPZ, linear color gamut compression from the first 2D device-independent color space to the second 2D device-independent color space if the target gamut is narrower than the source gamut. The method further comprises utilizing the same CGM module to perform, based on the TPZ, linear color gamut extension from the first 2D device-independent color space to the second 2D device-independent color space if the target gamut is wider than the source gamut.

The present invention includes systems and methods for a multi-primary color system for display. A multi-primary color system increases the number of primary colors available in a color system and color system equipment. Increasing the number of primary colors reduces metameric errors from viewer to viewer. One embodiment of the multi-primary color system includes Red, Green, Blue, Cyan, Yellow, and Magenta primaries. The systems of the present invention maintain compatibility with existing color systems and equipment and provide systems for backwards compatibility with older color systems.

Embodiments of the present disclosure relate to computer storage, methods, and systems for the optimization of accessible color themes. Systems and methods are disclosed that leverage the use of confusion lines to identify and highlight relationships between colors that may be inaccessible (e.g., indistinguishable) for a person with a vision impairment, such as a color vision deficiency. In some embodiments, a graphical user interface is provided that, based on a selection of colors in a color wheel, visually indicates curves of confusion for each color in the selection of colors. Each curve of confusion visually indicates a confusion of colors for a type of vision impairment, such as a CVD.
