Abstract: An image processing method and an image processing device are provided. The image processing method includes: determining a first width and a second width, where the second width is the width of a gap between display devices of target images on N screens, the first width is the width of a blind spot between source images corresponding to the N screens, N is an integer greater than 1, and the N screens are of a same size and are arranged side by side at a same height; and when the first width is different from the second width, adjusting the source images according to the determined first width and second width so as to obtain the target images, so that no mismatch exists in the stitched target images on the N screens.

Abstract: This application relates to the field of video coding technologies, and discloses a video coder and a corresponding method, to help improve video coding performance. In this application, encoding and decoding are collectively referred to as coding. A video coding method includes: determining a block split policy of a current picture block based on a size relationship between the width and the height of the current picture block; applying the block split policy to the current picture block to obtain a coding block; and reconstructing the obtained coding block to reconstruct the current picture block.

Abstract: A voice user interface display method and a conference terminal are provided. The method includes: when voice information input by a user into the conference terminal is received, a voice of the user is collected. A user voice instruction may be obtained based on the voice information input by the user. Identity information of the user may be obtained in real time based on the voice of the user. Further, user interface information that matches the user may be displayed based on the identity information of the user, the user voice instruction, and a current conference status of the conference terminal. The method improves diversity of display of the user interface information and improves user experience in using the conference system.

Abstract: This application provides a pixel collection circuit comprising an optical-to-electrical converter circuit configured to convert a collected optical signal into an analog signal; an analog-to-digital converter circuit configured to: receive the analog signal from the optical-to- electrical converter circuit; and perform analog-to-digital conversion on the analog signal to obtain a digital signal; a differential circuit configured to: receive the digital signal from the analog-to-digital converter circuit; and obtain a difference signal between a digital signal of a previous triggering moment and the digital signal of a current triggering moment; the previous triggering moment and the current triggering moment are determined by at least a digital clock signal; a comparison circuit configured to receive the difference signal from the differential circuit, and output a pulse signal. A digital component is used to implement the pixel collection circuit in the dynamic vision sensor, so as to reduce noise, reduce interference, and facilitate debugging.

Abstract: Embodiments of this application provide an electronic device and a picture processing method. The electronic device includes a rear cover, a front-facing camera, a rear-facing camera, and a light reflective apparatus. The light reflective apparatus may be switched between a usage state and an idle state. The picture processing method includes: controlling the light reflective apparatus to switch from the idle state to the usage state, when an operation that a user enables the front-facing camera is detected, where the usage state of the light reflective apparatus indicates that the light reflective apparatus is located on an object-facing side of the rear-facing camera and is configured to reflect a picture in a direction in which the front-facing camera is located, so that the rear-facing camera captures the picture reflected by the light reflective apparatus; separately obtaining a picture captured by the front-facing camera and a picture captured by the rear-facing camera; processing the picture captured by the rear-facing camera; and fusing the picture captured by the front-facing camera and a picture obtained by processing the picture captured by the rear-facing camera. In this application, a field of view of a picture taken by the front-facing camera can be increased with relatively low costs.
