According to an aspect, a display device includes: an image display unit in which pixels each including a plurality of sub-pixels are arranged in a matrix, the sub-pixels displaying a plurality of color components; and a signal processing unit that performs color conversion on an input video signal and outputs the resultant signal to a drive circuit that controls drive of the image display unit. The signal processing unit performs color conversion on first color information so as to increase luminance within an allowance range of a change in at least one of a hue and saturation, to generate second color information, the first color information being composed of three primary colors of red, green, and blue and derived based on the input video signal.

A display system for providing information display. The display system includes a display device, and control circuitry that controls the display device to display a gauge graphic including a scale for a vehicle parameter and a needle movable on the scale. The scale comprises a plurality of regions. The control circuitry further receives a first value of the vehicle parameter. The control circuitry further controls, based on a determination that the first value is between a first predetermined threshold and a second predetermined threshold, the display of a background color gradient on a first region of the plurality of regions based on the first value. The control circuitry further extends the background color gradient on a second region of the plurality of regions based on a determination that the first value exceeds the second predetermined threshold. The second region displays a solid color based on the background color gradient.

A color control user interface can include a controller, a display area, and a three-dimensional shape generated by the controller and disposed in the display area. The three-dimensional shape can include a first axis that represents a first range of selections for a first color factor, a second axis that represents a second range of selections for a second color factor, and a third axis that represents a third range of selections for a third color factor. A control engine of the controller can be configured to receive user selections having a first selection of the first color factor, a second selection of the second color factor, and a third selection of the third color factor. The control engine can also be configured to compare the user selections to light source information stored in memory, and send commands via a transceiver to at least one light source.

A method of color mapping a video signal represented in a first color volume from color mapping data to be applied on a video signal represented in a second color volume is disclosed. The method comprises:—color mapping (14) said video signal represented in a first color volume from said first color volume into said second color volume in the case where said first and second color volumes are different; and—color mapping (16) said color mapped video signal based on said color mapping data.

An electronic device may include a display and control circuitry that operates the display. The control circuitry may be configured to daltonize input images to produce daltonized output images that allow a user with color vision deficiency to see a range of detail that the user would otherwise miss. The daltonization algorithm that the control circuitry applies to input images may be specific to the type of color vision deficiency that the user has. The daltonization strength that the control circuitry applies to the image or portions of the image may vary based on image content. For example, natural images may be daltonized with a lower daltonization strength than web browsing content, which ensures that memory colors such as blue sky and green grass do not appear unnatural to the user while still allowing important details such as hyperlinks and highlighted text to be distinguishable.

The present disclosure provides a method and a device of driving a display and a display device. The method includes: conducting first image data combined with image data relevant to the first image data in time/space by a micro disturbance operation processing, to obtain second image data; and outputting the second image data. By changing the conventional driving mechanism, conducting the first image data combined with relevant image data with respect to a time axis by an operation processing, for example, adding a time axis correction parameter which may be dynamically adjusted and conducting a micro disturbance operation, so as to determine color gray scales of respective sub-pixels on the display according to an adjusted driving circuit, which may make colors of image data on the display more plentiful and optimize display effect.
