Abstract: This application discloses a touch component, a touch chip, and a terminal device, and relates to the touchscreen field, to improve a signal-to-noise ratio of a touchscreen. The touchscreen includes a display panel, a first touch circuit, and a second touch circuit. The first touch circuit is located in a first touch zone of the display panel, and the second touch circuit is located in a second touch zone of the display panel. A plurality of detection pads of the first touch circuit and a plurality of detection pads of the second touch circuit are independently electrically connected to the touch chip. The touch chip outputs drive signals to a plurality of drive pads of the first touch circuit, and receives first detection signals from the plurality of detection pads of the first touch circuit, to detect a touch operation in the first touch zone.

Abstract: Embodiments of this application provide a cover image determining method and apparatus, and a device. The method may include: extracting a plurality of key frames from a video; determining at least one first image in the plurality of key frames, where a correlation between a principal object included in the first image and the video is greater than or equal to a preset threshold; obtaining an object type of a principal object in each first image, where the object type is one of the following: a character type, an item type, a landscape type, or a scene type; and determining a cover image of the video based on the at least one first image and the object type of the principal object in each first image. In this way, quality of the determined cover image is improved.
