Abstract: Embodiments of this application provide a parameter adjustment method, a display control method, and an electronic device. The electronic device includes a front camera and a display screen, and the front camera is configured to run based on an initial exposure parameter that matches an ambient light brightness in response to a first instruction, to capture an image. The parameter adjustment method includes: obtaining, when the display screen displays data, an image captured by the front camera; calculating an image brightness of the image by using image data of the image, adjusting the initial exposure parameter based on a difference between the image brightness of the image and a standard brightness, to obtain an exposure parameter adjustment value, the exposure parameter adjustment value being configured for the front camera to run based on the exposure parameter adjustment value in response to a second instruction, to capture an image.

Abstract: An off-screen display control method, an electronic device, and a computer-readable storage medium. The off-screen display control method includes: enabling a face detection function when a display screen of an electronic device is in an off-screen state and obtaining image data through a front camera; determining, by the electronic device, that the image data includes a part or the entire of a face image, and displaying an off-screen display interface on the display screen; and determining, by the electronic device, that the image data does not include a part or the entire of a face image, and maintaining the off-screen state on the display screen.

Abstract: This application provides an exposure parameter adjustment method, device, and storage medium. The method includes: obtaining a face box of a first-frame image and a second-frame image, where the face box of the first-frame image is used to indicate a region of a face in the first-frame image, and the second-frame image is a next-frame image of the first-frame image; correcting the face box of the first-frame image to obtain a second-face box; cropping the second-frame image based on the second-face box to obtain a face image of the second-frame image; and adjusting an exposure parameter based on the face image of the second-frame image. In this solution, a face box of a previous-frame image is first corrected, then a face image is cropped by using the second-face box, so that a face image obtained through cropping and an actual face region in an image that is cropped are consistent.
