Abstract: Disclosed are a zoom method and an apparatus, to improve zoom accuracy of a camera module. The method includes: controlling, based on a target focal length, the lens to move in different subregions when the lens moves in an operation region, and determining position information of the lens based on a position detection relationship of a subregion in which the lens is currently located. The lens is controlled to move based on a position that is of the lens and that is detected when the lens moves, so that the lens can more accurately stop at a position corresponding to the target focal length. This helps improve focusing accuracy of the camera module.

Abstract: An SPI-based data transmission system is provided. In the system, a master SPI apparatus enables a first slave SPI apparatus by using a combination of a first and a second chip select signal. In response to the master SPI apparatus driving the first chip select signal to be in an enable state and driving the second chip select signal to be in a disable state, the master SPI apparatus controls a second slave SPI apparatus to send data using a data line. The master SPI apparatus further receives data by using the data line, and the first slave SPI apparatus receives data using the data line. When the first chip select signal is in the enable state and the second chip select signal is in the disable state, the master SPI apparatus and the first slave SPI apparatus can simultaneously receive data transmitted by the second slave SPI apparatus.

Abstract: This application discloses an image generation method and apparatus, and an electronic device, and relates to the field of image processing. The method includes: acquiring a spectrum image of a first scene by using a first camera that supports more photosensitive bands than a second camera, and acquiring a color image of a second scene by using a second camera, where both the color image and the spectrum image include a same target object; then, correcting a color cast of a reconstructed spectrum image of the color image based on the spectrum image, to acquire a plurality of corrected reconstructed spectrum images; and fusing the plurality of corrected reconstructed spectrum images to generate a corrected color image whose color is closer to a color of the second scene than a color of the color image.
