For convenience of description, the above-mentioned devices are collectively referred to as electronic devices. The following describes embodiments of the present application in detail.
Referring to fig. 2, fig. 2 is a schematic flowchart of a photo preview method according to an embodiment of the present application, and as shown in fig. 2, the photo preview method according to the embodiment of the present application includes the following steps:
s201, the electronic equipment acquires the image displayed in the current preview window.
The activation manner of the preview window may be various, for example, the activation manner is activated in an application such as a camera, or the activation manner is activated in a shooting window of an application program such as instant messaging, and the like, which is not limited herein.
The electronic device may display a plurality of preview windows on the display interface, and the current preview window is only one of the plurality of preview windows. The images displayed in the preview windows may be the same or different, and the embodiments of the present application are not limited thereto. The number, position and shape of the multiple preview windows may be various in the embodiment of the present application, for example, 2, 3 or 4.
For example, when the number of the preview windows is 4, the interface containing 4 preview windows may be in a 4-grid style as shown in fig. 2-1, wherein the first and second durations may be circular, the third and fourth durations may be rectangular, and the current preview window is only the first preview window; for another example, when the number of the preview windows is 2, the interface containing the 2 preview windows may be in a 2-grid style as shown in fig. 2-2, and the current preview window is only the first preview window.

However, in the meantime, the occupied memory resources and processor resources are also increased during the image processing. Therefore, in the image previewing process, the resolution can greatly affect the previewing effect of the single-frame picture, and if the resolution is reduced, the image seen by the user in the previewing process is blurred. Thus, when the resolution is adjusted alone, the user can still view the preview image more smoothly, but there is a loss in image detail.
The frame rate is used to measure the number of display frames per second. Therefore, the reduction of the frame rate does not affect the preview effect of the single-frame picture, but if the frame rate is low, the user may feel that the preview image viewed is delayed. That is, when the frame rate is adjusted alone, the user can still clearly view the details of the preview image, but with a delay.
