A character string display processing method is provided. The method includes: receiving a character display instruction; performing, in response to determining a target character string in the character string set does not include a character of a preset type, first rendering preprocessing on a target character included in the target character string to obtain a first rendered data set, and generating a rendering instruction about the character string set according to the first rendered data set; and performing, in response to determining the target character string includes a character of a preset type, second rendering preprocessing on the target character string to obtain a second rendered data set, and generating a rendering instruction about the character string set according to the second rendered data set.

Embodiments of the present disclosure relate to a method for determining an offset distance of a splicing screen in a multi-screen display system, a method for driving the multi-screen display system, and a related control apparatus. In the method for determining the offset distance of the splicing screen, a preset image is displayed in each of a plurality of splicing screens of the multi-screen display system. A feature point is determined in the preset image, and a position of the feature point of each splicing screen in the multi-screen display system is determined. Based on the positions of the feature points, at least one of a vertical offset distance and a horizontal offset distance of each splicing screen is determined.

An output content generation device, includes: a first calculation unit that calculates a size, in a display region of a display device, of each of pieces of information to be displayed in the display region; a determination unit that determines whether or not the pieces of information are arrangeable in the display region, based on the size of each of the pieces of information and a size of the display region; and a generation unit that allocates the pieces of information in a plurality of screens accommodated in the display region in a distributed manner, and generates output content of the pieces of information, when the pieces of information are not arrangeable in the display region, thereby enabling information to be legibly viewable.

In some examples, with respect to augmented reality based virtual dashboard implementation, features of a physical computer system display may be identified. Based on the identified features of the physical computer system display, boundaries of a virtual dashboard may be determined. Based on the determined boundaries of the virtual dashboard, an augmented reality display may be generated for an augmented reality device. The augmented reality display may include a view of the physical computer system display and may further include a virtual reality display of the virtual dashboard adjacent to and outside of the identified features of the physical computer system display. The virtual dashboard may include content displayed thereon.

Techniques for calibrating cameras and displays are disclosed. An image of a target is captured using a camera. The target includes a tessellation having a repeated structure of tiles. The target further includes unique patterns superimposed onto the tessellation. Matrices are formed based on pixel intensities within the captured image. Each of the matrices includes values each corresponding to the pixel intensities within one of the tiles. The matrices are convolved with kernels to generate intensity maps. Each of the kernels is generated based on a corresponding unique pattern of the unique patterns. An extrema value is identified in each of the intensity maps. A location of each of the unique patterns within the image is determined based on the extrema value for each of the intensity maps. A device calibration is performed using the location of each of the unique patterns.

An apparatus for controlling digital signage according to an embodiment of the present invention includes a memory, a display, and a controller. The controller selects a background graphic image to which a virtual digital signage is installed with reference to the memory, selects at least one of the number or size of the virtual digital signage with reference to the memory, designates a specific location, in the selected background graphic image, in which the virtual digital signage is installed with reference to the memory, and selects a source video which is displayed through the virtual digital signage in the specific location with reference to the memory.

The present application relates to the technical field of optics, and provides a method for implementing target object positioning, including: obtaining a target object position of a target object; and providing the target object position to a display controller without involving an AP. The method for implementing target object positioning provided by the present application is capable of avoiding occupying a large amount of resources of the AP due to the processing for the target object position as much as possible. The present application further provides an apparatus for implementing target object positioning, a display device, a computer-readable storage medium, and a computer program product.

An interface of a device can allow a resource to set a location of a PiP window that is different than the default or predetermined location of the PiP window. The device can set a Picture-in-Picture (PiP) window location. The device can receive a PiP window location request that comprises one or more location parameters that indicate a location for display of a PiP window. The device can set the PiP window location based on the one or more location parameters. The device can then send the PiP window location to a PiP control management service. The resource then is able to control the placement of information associated with the resource to provide the user with an improved user experience.
