Abstract: A charging device comprises a charging chip and a processor. The charging chip is configured to convert a power supply voltage into a battery voltage to charge the battery, where the power supply voltage is greater than a limiting power supply voltage, and the battery voltage is less than a limiting battery voltage. The processor is configured to: when a first condition is met, increase both the limiting power supply voltage and the limiting battery voltage, or decrease a charging current while increasing the limiting battery voltage; or when a second condition is met, decrease both the limiting power supply voltage and the limiting battery voltage, or increase the charging current while decreasing the limiting battery voltage.

Abstract: A method and a terminal are provided by various embodiments of the present invention in which: M cameras are configured to continuously shoot a same scene for K times, where M≥2, K≥2, and each of the M cameras simultaneously collects one frame of image at each time of shooting; and a processor, connected to the M cameras and configured to perform registration on images obtained at the K times of shooting, and perform temporal and spatial filtering on the registered images. In the embodiments of the present invention. Because the multiple cameras simultaneously collect an image at each time of shooting, a time interval at which a particular quantity of images are collected by the terminal is shorter than that at which the particular quantity of images are collected by a single camera, and a probability of an occurrence of hand trembling or object motion within the time interval also correspondingly decreases.

Abstract: A photographing method, a photographing apparatus, and a terminal, where the method includes receiving a camera turn-on instruction, previewing a preview image collected by the camera based on the received camera turn-on instruction, where in a preview state, an operation mode of an image sensor of the camera is an average pixel combination mode, and photographing the preview image when detecting that luminance of at least one pixel in the preview image is less than a preset condition, where when the preview image is being photographed, the operation mode of the image sensor of the camera is a sum pixel combination mode. In this way, luminance of a photographed image can be increased, and a problem that an image cannot be photographed in low light can be resolved.

Abstract: A method for calculating a dual-camera relative position provided in the present disclosure includes obtaining M groups of dual-camera images, where each group of dual-camera images in the M groups includes two images obtained by photographing a same scene by dual cameras at the same time, screening the M groups of dual-camera images to obtain Q groups of dual-camera images that can be used to calculate the dual-camera relative position, obtaining dual-camera relative position parameters corresponding to each group of dual-camera images in the Q groups according to each group of dual-camera images in the Q groups, and obtaining optimal dual-camera relative position parameters from the Q groups of dual-camera relative position parameters. Therefore, the dual-camera relative position can be calculated when a scene is relatively difficult to recognize.
