A perceived gamut (PG) of a physical display device presenting frames of an image sequence to a human viewer may be increased. An interface of the system 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, the input color data being given in a specified color space. A perceived color computation module computes for each particular frame of the received image sequence perceived colors of each pixel and a frame-specific adapted white point. An optimizer module applies a chromatic adaptation transformation to each window frame to determine display gamut adjusted perceived colors of each pixel of the respective frame and an error per window frame. The chromatic adaptation transformation is updated for all window frames to minimize the determined error, and the current frame is output to the display.

A medical support system includes a processing circuit configured to: acquire medical data on a specific patient over time; cause a display to display a display screen on which one or more measurement values in the medical data are displayed; detect an alert value that satisfies a determination condition from the one or more measurement values included in the medical data every time the medical data is acquired; and highlight a warning area in which the alert value is displayed on the display screen, and change a dept of a background color of the warning area in accordance with an importance degree relating to the alert value.

An example display system includes a load engine and a calibration engine. The load engine causes an inquiry for current calibration measurement data and retrieves factory calibration measurement data when the current calibration measurement data is unavailable. The calibration engine receives a target set of display characteristics, generates a color profile from a native panel performance representation to operate a display according to the target set of display characteristics, and causes adjustment of a display according to a difference between the target set of display characteristics and the native panel performance representation using the generated color profile.

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. A six-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.

An adaptation status judging unit (112) judges an adaptation status of a driver to a color. A goal color decision unit (113) decides a goal color of a display range based on the adaptation status of the driver. An applicable color decision unit (115) decides an applicable color of a display portion on a screen of a display based on the goal color, the display portion displaying information. A control unit (116) controls the display based on the applicable color of the display portion.

A microlens array substrate includes a substrate having a first surface and a plurality of recesses corresponding to a plurality of pixels, and a microlens array including a plurality of microlenses corresponding to the plurality of recesses. The microlenses each have a refractive index different from a refractive index of the substrate, and each have a light incident surface and a light exiting surface. The light incident surface has a first curvature region and a second curvature region. The second curvature region surrounds the first curvature region when viewed along the optical axis of one microlens and has a curvature greater than the curvature of the first curvature region. The light exiting surface includes a light collecting structure configured to converge the light incident via the light incident surface. The light collecting structure overlaps with part of the first curvature region when viewed along the optical axis.
