A handheld imaging device has a data receiver that is configured to receive reference encoded image data. The data includes reference code values, which are encoded by an external coding system. The reference code values represent reference gray levels, which are being selected using a reference grayscale display function that is based on perceptual non-linearity of human vision adapted at different light levels to spatial frequencies. The imaging device also has a data converter that is configured to access a code mapping between the reference code values and device-specific code values of the imaging device. The device-specific code values are configured to produce gray levels that are specific to the imaging device. Based on the code mapping, the data converter is configured to transcode the reference encoded image data into device-specific image data, which is encoded with the device-specific code values.

A method for scrolling visual page content in a predetermined direction on a screen of a display device can include displaying at least one visual object on the screen, detecting a scrolling action for moving the at least one visual object on the screen, detecting information on scrolling behavior of the displayed visual object, and displaying a scrolling of the visual object on the screen based on the detected information on the scrolling behavior.

An embodiment modular light-emitting diode (LED) display panel includes attachment points for use in attachment as part of a multi-panel modular LED display, a printed circuit board including a first side and an opposite second side, and a plastic casing attached to the opposite second side of the printed circuit board. A perimeter of the plastic casing is substantially rectangular and has a height and a width. The modular LED display panel further includes a display surface including a plurality of LEDs arranged as pixels and attached to the first side of the printed circuit board. The pixels are arranged in a rectangular array including at least fifty pixels. Each of the pixels of the rectangular array is spaced from each respective adjacent pixel of the rectangular array by a pitch. The pitch is a predetermined constant number. The pitch does not depend on the height and the width.

A screen mirroring display method implemented by a first electronic device, where the method includes displaying a first display interface, receiving a screen mirroring instruction for projecting the first display interface onto a second electronic device, determining a first target control in the first display interface in response to the screen mirroring instruction, and sending a first message to the second electronic device, where the first message includes a drawing instruction of the first target control to prompt the second electronic device to draw a first screen mirroring interface according to the drawing instruction, where the first screen mirroring interface includes the first target control.

Adaptive recoloring of displayed digital content automatically pursues specified active color palette goals while adhering to specified active color palette constraints. Source code editors, word processors, and other programs are enhanced by adaptive recoloring. Recoloring rules may specify coloring roles, colors, tolerances, color spaces, metrics, and other criteria. Recoloring may be triggered by a zoom or another change in user focus, by a brightness change, a screen size change, by notice of a user perception change, or by another event. Recoloring improves text legibility, assists user focus, compensates for differences in color perception and emotional impact, and increases color availability without degrading usability, for example. Transitions between words or other display items can be heightened. Branding colors may be preserved, in logos and text. Automatic selections may be overridden by a user command or by interactive tuning, with warnings given as appropriate.

A display system includes an HMD mounted on a head of a user, and a smartphone to which the HMD is coupled, and the smartphone includes a touch sensor that accepts a position input operation and detects coordinates of an operating position with reference to set coordinate axes, a magnetic sensor that detects an orientation of the touch sensor, and an adjustment unit that adjusts an orientation of the coordinate axes, based on a detection result of the magnetic sensor.

An assortment of Cognitive Load Reduction (CLR) systems is disclosed. The systems are worn by a user, rather than appearing on displays in front of the user. This arrangement allows the systems to be movable and less confining. This in turn results in the wearer employing the CLR systems in a wider variety of environments than earlier mechanisms.

A flexible display device is provided. The flexible display device includes: a display; a sensor configured to detect at least one rolling characteristic in response to the display being rolled; and a controller configured to perform a first function of the flexible display device based on the detected at least one rolling characteristic.

An information processing device including a display unit, a detector, and a first control unit. The display unit capable of providing the user with a field of view of a real space. The detector detects an azimuth of the display unit around at least one axis. The first control unit includes a region limiter, a storage unit, and a display control unit. The region limiter is capable of limiting a display region of the field of view along a direction of the one axis in three-dimensional coordinates surrounding the display unit. The storage unit stores images including information relating to a predetermined target present in the field of view with the images being made corresponding to the three-dimensional coordinates. The display control unit is configured to display, based on an output of the detector, an image in the three-dimensional coordinates, which corresponds to the azimuth, in the field of view.

The present invention provides a data processing method and an electronic terminal. The electronic terminal obtains target data that includes at least one data item, converts the target data into a data image by using a data visualization technology, and then sets the data image as wallpaper, where the data image includes at least one graphic element, and the graphic element is in a one-to-one correspondence with the data item. The target data is user data, and may include operation event information of operating the electronic terminal by a user, or information that is associated with a user account and that is based on at least one network platform, so as to automatically generate the wallpaper, show the user data to the user by using the wallpaper, and improve user experience.
