Abstract: The present disclosure provides an ultrasonic imaging method and apparatus. The apparatus includes an ultrasonic signal emission source and a receiving array including ultrasonic signal receiving circuits; the method includes: turning on the source to perform emission of ultrasonic waves toward an object to be detected and causing the ultrasonic waves to propagate through the object, a depth-wise direction of which is along a propagation direction of the ultrasonic waves; after a first predetermined time period having elapsed since the source was turned on, turning on the receiving array to receive reflected echoes returning from a first section plane of the object to be detected perpendicular to the depth-wise direction; thereafter, turning off the receiving array, storing the reflected echoes by the ultrasonic signal receiving circuits and acquiring reflected echo signals, and successively reading the reflected echo signals from the ultrasonic signal receiving circuits during a reading time period.

Abstract: A texture recognition apparatus and an electronic apparatus are provided. The texture recognition apparatus has a touch side surface, and includes a light source array, an image sensor array and a light shielding matrix, the light source array includes a plurality of light sources; the image sensor array includes a plurality of image sensors, the plurality of image sensors are configured to receive light emitted from the plurality of light sources and reflected by a texture to the plurality of image sensors; the light shielding matrix includes a plurality of light shielding patterns arranged in an array, each of the plurality of image sensors includes a photosensitive element; the plurality of light sources do not overlap with the plurality of light shielding patterns, a photosensitive element of each of the plurality of image sensors at least partially overlaps with at least one or the plurality of light shielding patterns.

Abstract: The present disclosure provides a method and apparatus for generating a front-end code. The method includes: acquiring attribute information of view elements in a target UI view interface; determining child view elements corresponding to a given parent view element based on the attribute information of the view elements; determining, according alternately to row correlation information and column correlation information between the child view elements, nodes at different levels of a DOM, tree corresponding to the parent view element except a root node until each leaf node is an individual child view element, to obtain the DOM tree; and generating a complete front-end code corresponding to the target UI view interface based on the DOM tree.
