An input display device includes: a processor to execute a program; and a memory to store the program which, when executed by the processor, results in performance of steps including: receiving an input of a track by a receiving unit; generating a track image showing the track; acquiring a character string; and displaying the character string acquired in the acquiring to be superimposed on the track image. When the character string is acquired in the acquiring before the track image is generated, the displaying the character string is stood by.

Various implementations disclosed herein include devices, systems, and methods that use an object as a background for virtual content. Some implementations involve obtaining an image of a physical environment. A location of a surface of an object is detected based on the image. A virtual content location to display virtual content is determined, where the virtual content location corresponds to the location of the surface of the object. Then, a view of the physical environment and virtual content displayed at the virtual content location is provided.

Devices, methods and computer program products that facilitate automated adjustment of size or configuration of head up display image in a vehicle. A device can include a memory and a processor that executes computer executable modules. The computer executable modules can include: a head up display that generates an image visible to a driver of a vehicle within an eye box, a detection module that determines position of the driver's eyes or head relative to position of the eye box, and an adjustment module that adjusts size or configuration of the image within the eye box in response to the determined driver's eye or head position.

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.

The invention relates to an electronic display device on board an aircraft capable of landing or maintaining a hover above a landing zone and comprising: a module for calculating a distance between the aircraft and the landing zone according to a horizontal direction and for determining a height of the aircraft; and a module for displaying an exocentric aircraft symbol, positioned at a distance said exocentric from the aircraft according to an exocentric direction and at a height difference said exocentric relative to the aircraft, the display module being further configured to display an exocentric landing zone symbol, positioned at a distance from the landing zone equal to the exocentric distance according to the exocentric direction and at the same height as the exocentric aircraft symbol.

At least two display areas are formed after an action such as folding a foldable screen of a device. The device displays a first display interface comprising a display interface of a first application. The device detects a first operation such as unfolding the screen and in response, displays a second display interface comprising a first display area and a second display area. The device displays the display interface of the first application in the first display area of the second display interface, and displays at least one application icon in the second display area of the second display interface. At least one application corresponding to the at least one application icon is associated with a first content in the display interface of the first application, and the at least one application comprises a first target application. The device detects a second operation acting on an application icon corresponding to the first target application and in response, displays a third display interface that comprises the first display area and the second display area. The device displays the display interface of the first application in the first display area of the third display interface, and displays, in the second display area of the third display interface, a first interface of the first target application, the first interface being associated with the first content.

An electronic apparatus is provided. The electronic apparatus includes a display device, a sensor, and a processor. The display device receives an image data. The display device includes a display panel and displays an image related to the image data on the display panel. A reference image point of the image is displayed on a first location on the display panel. The sensor detects a movement status of the electronic apparatus when the electronic apparatus shakes to generate at least one movement parameter. The processor calculates compensation data according to the at least one movement parameter and size information of the display panel. When the display device receives the compensation data, the display device displays the image by shifting the reference image point of the image from the first location to a second location on the display panel to display according to the compensation data.

The signal processing device according to an embodiment of the present disclosure includes: a frame buffer to store an input image and output an output image, an output synchronization signal calculator to calculate an output synchronization signal based on an input synchronization signal and a size or a position of the output image in comparison with the input image, and an output synchronization signal output interface to output a variable output synchronization signal of which a start timing changes based on a signal from the output synchronization signal calculator, wherein a difference between a start timing of the input synchronization signal and a start timing of the output synchronization signal changes based on the size of the output image. Accordingly, a delay time may be reduced in response to the output image having a size different from a size of the input image being output.
