Abstract

This disclosure provides a display method, a mobile terminal, and a computer-readable storage medium. The mobile terminal sequentially receives a first zooming operation, at least one second zooming operation, and a third zooming operation. The mobile terminal first responds to the first zooming operation, and obtains a first zoomed image at a zoom ratio of the first zooming operation, then responds to the third zooming operation and correspondingly obtains a third zoomed image, and displays the third zoomed image. The third zooming operation that is generated later may be processed and displayed in advance before the at least one second zooming operation that is received earlier. The time for responding to all or some image obtaining operations of the at least one second zooming operation is reduced, so that a display delay of a zooming operation received later is reduced, and hand-following smoothness of the zooming operation is improved.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This is a continuation of International Patent Application No. PCT/CN2024/100202, filed on June 19, 2024, which claims priority to Chinese Patent Application No. 202310807236.5, filed on July 3, 2023, both of which are incorporated herein by reference. TECHNICAL FIELD Embodiments of this disclosure relate to the field of terminal technologies, and in particular, to a display method, a mobile terminal, and a computer-readable storage medium. BACKGROUND With the development of science and technology, mobile terminals such as mobile phones have more and more powerful functions. A photographing function of the mobile terminal can implement front and rear photographing, image beautification processing, zooming, and the like. The mobile terminal is usually assembled with a plurality of groups of lenses. Different lenses correspond to different focal lengths, and lenses with different focal lengths can collect images of different distances, different field of views, and different definitions. A zooming operation (Zoom) of the mobile terminal is to adjust positions of several groups of lenses with different focal lengths, to change focal lengths of the adjusted lenses, so as to collect images of different focal lengths. When using the mobile terminal to perform photographing preview, a user may apply different zooming touch actions on a photographing preview interface of the mobile terminal. The mobile terminal detects a touch parameter of the zooming touch action of the user, to generate a corresponding zooming request, delivers the generated zooming request to a corresponding functional module to process the zooming request, and displays a finally obtained preview image. When performing photographing preview, the user may have different zooming requirements successively, so that the user may trigger a plurality of zooming operations, and correspondingly, a plurality of zooming requests are generated. The mobile terminal sequentially processes the zooming requests and displays corresponding preview images according to a sequence in which the zooming requests are generated. As a result, a zooming request generated by the mobile terminal in real time may be processed only after being triggered for a period of time, and a preview image corresponding to the zooming request may also be displayed only after a period of time, and consequently, a delay from applying the zooming touch operation to displaying a zoomed preview image is long. It can be learned that, when an existing mobile terminal performs photographing preview, a response delay of the zooming operation is long, and hand-following smoothness of the zooming operation is poor. Embodiments of this disclosure provide a display method, a mobile terminal, and a computer-readable storage medium, to implement a solution in which a zooming operation received later jumps to a zooming operation received earlier to cut in line for processing and display in advance, thereby reducing response and display delays of a newly received zooming operation, and optimizing hand-following smoothness of zooming display. To achieve the foregoing objective, the following technical solutions are used in the embodiments of this disclosure: According to a first aspect, a display control method is provided. A mobile terminal successively receives a plurality of zooming operations, sequentially including a first zooming operation, at least one second zooming operation, and a third zooming operation. Receiving time of the first zooming operation is earlier than receiving time of the third zooming operation, the first zooming operation and the third zooming operation are spaced by at least one second zooming operation, and zoom ratios of different zooming operations may be different. The second zooming operation mentioned in this specification may be equivalent to the first zooming operation mentioned in the claims, and the third zooming operation mentioned in this specification may be equivalent to the second zooming operation mentioned in the claims, and details are not described one by one again. In addition, the first zooming operation mentioned in this specification may exist or may not exist during actual photographing, and this is not limited. The mobile terminal first responds to the first zooming operation, and obtains a first zoomed image at a zoom ratio of the first zooming operation. Before responding to all the second zooming operations or displaying second zoomed images corresponding to all the second zooming operations, the mobile terminal first correspondingly responds to the third zooming operation, obtains a third zoomed image, and displays the third zoomed image. A process of responding to a zooming processing operation may sequentially include: zooming request generation, zooming request delivery, an image capture operation, an image signal front-end processing operation, a spatial alignment transform processing operation, an image
