The display method includes the steps of receiving input of first information representing an amount of an dilation process or a erosion process on a first mask image including a mask region, generating a second mask image by performing the dilation process or the erosion process corresponding to the first information based on an edge of the mask region on the first mask image, and displaying a projecting image obtained by superimposing the second mask image on an input image.

A display method is applied to electronic equipment including a display assembly. A display content displayed by the display assembly includes a background and an object for reading located on the background. The display method includes: differentiating grayscales of background pixels of the background; and displaying the background based on the background pixels with the differentiated grayscales, and displaying the object for reading.

A displaying method including receiving an input of a threshold value, generating, by using the threshold value, a second image showing a mask region of a first image that is a region where an input image is displayed or a non-mask region of the first image that is a region where the input image is not displayed, and displaying a projection image obtained by superimposing the second image on the input image.

An image processing method, including the following steps: receiving an original image signal, wherein the original image signal includes a plurality of original pixel values; identifying an edge of at least one object in the original image signal to generate a contour image signal; and correcting the original image signal according to the contour image signal to generate an enhanced image signal.

A method of providing a graphical output may include scanning at least a portion of a user's face using a sensor; generating a depth map using the scan; and determining a similarity score between the depth map and a set of stored biometric identity maps that are associated with a registered user. In response to the similarity score exceeding a threshold, the user may be authenticated as the registered user. The method may further determine a corrective eyewear scenario, select a display profile that is associated with the corrective eyewear scenario, and generate a graphical output in accordance with the selected display profile.

An e-paper display device including an e-paper display panel, a graphics library and a display controller is provided. The display controller is coupled to the e-paper display panel. The display controller is configured to receive a line segment input signal and call the graphics library, and then drive, using a set of signal waveforms, the e-paper display panel to display a line segment. The set of signal waveforms is generated according to the line segment input signal and the graphics library. The line segment includes at least one gray level. In addition, a method for driving an e-paper display device is also provided.

An apparatus and method for generating font by means of METAFONT by using outline font are disclosed. The disclosed method for creating a Metafont font may be performed at an apparatus that includes a processor, where the method may include: (a) creating an intermediate code by adding an attribute for Metafont to a code of an outline font written in XML; and (b) creating the Metafont font by using information of points obtained by parsing the intermediate code.

Disclosed are a text boundary processing method, a display panel and a computer-readable storage medium. The method includes: acquiring a grayscale value of each sub-pixel in a display panel; determining a current sub-pixel is a text boundary according to a grayscale value of the current sub-pixel and grayscale values of sub-pixels adjacent to the current sub-pixel; and interchanging grayscale values of a red sub-pixel and a blue sub-pixel in a sub-pixel group where the current sub-pixel is located, where, the sub-pixel group consists of the current sub-pixel and two sub-pixels adjacent to the current sub-pixel in a same row where the current sub-pixel is located.

A system may render glyphs based on stored textures without loss of quality at subpixel scales. The system may determine a content of a pixel of a display corresponds to a glyph, determine a subpixel alignment offset of a specified screen coordinates for the glyph with respect to the pixels of the display, based on the subpixel alignment offset, select one or more versions of the glyph from a plurality of versions of the glyph, a first version of the glyph of the plurality of versions of the glyph having a corresponding first subpixel alignment offset and a second version of the glyph of the plurality of versions of the glyph having a corresponding second subpixel alignment offset, and generate a display version of the pixel based on the selected one or more versions of the glyph and the subpixel alignment offset of the specified screen coordinates.
