A data processing apparatus includes allocation circuitry to allocate a graphical feature for a virtual environment to a respective layer from a plurality of respective layers in dependence upon one or more properties for the graphical feature, where the plurality of respective layers comprise a mobile layer and at least one of a mobile re-projection layer and a static re-projection layer, rendering circuitry to render graphical features allocated to respective different layers of the plurality of respective layers with a different rendering quality, and an output image generator to generate an image for display according to a viewpoint of a virtual camera, where the image includes graphical features allocated to respective different layers of the plurality of layers.

Techniques are described for enhancing the perceived gamut (PG) of a physical display device presenting frames of an image sequence to a human viewer wherein the gamut (DG) of the display device is given by the primary colors of the display device. An interface receives a sequence of frames from an image sequence source with each frame having input color data associated with each pixel of the respective frame. A white point computation module computes frame-specific target white points (TWP) to which the viewer would adapt when watching a respective frame on a display capable of showing all perceivable colors. A chromatic adaptation transformation module applies a temporal filter function to the target white points of all frames within a sliding window to compute a filtered white point and applies a chromatic adaptation transformation to one or more future frames by using the filtered white point.

A method includes presenting a representation of a multi-panel display of an operator console on a touchscreen separate from the multi-panel display. The representation includes multiple placeholders associated with multiple panels of the multi-panel display. The method also includes receiving user input via the touchscreen, where the user input identifies at least one of the placeholders associated with at least one of the panels and a desired function. The method further includes performing the desired function to one of change first content presented in the at least one panel or change second content presented on the touchscreen based on the first content presented in the at least one panel. The desired function could include pushing the first content to the at least one panel or pulling the second content from the at least one panel.

An object is to suppress deterioration of a displayed image even when a refresh rate is reduced in displaying a still image. A liquid crystal display device includes a pixel transistor electrically connected to a pixel electrode, and a capacitor having one electrode electrically connected to the pixel electrode and the other electrode electrically connected to a capacitor line. The pixel transistor is turned on and a voltage based on an image signal is supplied to the pixel electrode, and then, the pixel transistor is turned off so that a holding period during which the pixel electrode holds the voltage based on the image signal starts. A holding signal corresponding to change of the voltage based on the image signal in the pixel electrode in the holding period is supplied to the capacitor line so that a potential of the pixel electrode is constant.

A method is provided for causing a display of at least one content item and for enabling movement of the at least one content item. The method also causes a portion of the at least one content item to be highlighted relative to another portion of the at least one content item while the at least one content item is being moved. The portion of the at least one content item may be highlighted in various manners including by changing the brightness of the portion, applying a graphical effect to the portion and/or causing movement of the portion, such as by zooming the portion of the at least one content item. A corresponding apparatus and computer program product are also provided.

Eye-friendly display that can reduce eye strain on a user is achieved. A display system includes a display portion, an input portion, and a control portion. The display portion is configured to display an image. The input portion is configured to sense an input from a user and output a signal to the control portion. The control portion is configured to execute a first mode and a second mode. In the first mode executed by the control portion, an image is displayed on the display portion by an interlace method. In the second mode executed by the control portion, an image is displayed on the display portion by a progressive method. The control portion is configured to switch between the first mode and the second mode in accordance with the signal.

Provided are a projection type display device and an operation assistance method that enable an operator to enjoy an operation assistance function even in the case of occurrence of abnormality in an optical modulation unit or an image information input unit during operation of a vehicle. A system control unit 47 of a HUD, if sensing abnormality in an optical modulation device 44 and a drive unit 45, stops a light source unit 40 and, furthermore, in the case of image information generated by a projected image information generation unit 52 including image information that calls attention of the operator to the front field of view, displays an alert image based on the image information on a liquid crystal display device 61 in a meter cluster.

A display device includes a data driver, line selectors, and a controller. The data driver provides data signals to output lines. The line selectors control connections between the output lines and data lines. The controller selects a normal driving mode or a low frequency driving mode as a panel driving mode and controls a scan driver, the data driver, and the line selectors based on the panel driving mode. Each line selector respectively connects the output lines to the data lines when the panel driving mode is the normal driving mode, and progressively connects one of the output lines to some of the data lines when the panel driving mode is the low frequency driving mode.
