in step S101, when a photographing instruction is received, a prompt box for setting the resolution of an image to be displayed is displayed on a user interface.

As shown in fig. 1B, a prompt box 11 may be displayed on the currently displayed image preview interface, and a user may input the resolution of an image that the user needs to display on the display interface in the prompt box 11, and receive a photographing instruction through the virtual key 12.

In step S102, determining the resolution of the image to be displayed based on the prompt box; the resolution ratio of the image to be displayed is between a first resolution ratio and a second resolution ratio, wherein the first resolution ratio is the resolution ratio of a first image with a first pixel arrangement mode, and the second resolution ratio is the resolution ratio of a second image with a second pixel arrangement mode; the pixels of the same color component are distributed in a square array in the first pixel arrangement mode, and the second pixel arrangement mode is a standard Bayer arrangement mode of the photosensitive element.

In one embodiment, the square array may be an N × N array, where N is greater than or equal to 2, and as shown in fig. 1C, the pixel arrangement pattern inherent to the photosensitive elements is a four-in-one (4in1) pixel arrangement mode, that is, the 2 × 2 array corresponding to the same color component is taken as one large pixel point and is regarded as a standard Bayer arrangement pattern, and accordingly, the resolution of the first image is one fourth of the resolution of the photosensitive elements. Based on the color components in the 2 × 2 array shown in fig. 1C, the color components of the large pixels corresponding to the 2 × 2 array can be determined, and then the first pixel arrangement mode shown in fig. 1D is obtained. In one embodiment, a frame of raw image data as shown in fig. 1C is collected by a photosensitive element, and the raw image data is converted into a first pixel arrangement as shown in fig. 1D, so as to obtain a first image. A pixel point on the first image is obtained through four pixel points of the same color component of the photosensitive element, which is equivalent to increase of the photosensitive area of the pixel point, so that the first image has low resolution and high light sensitivity.

In one embodiment, the standard Bayer arrangement pattern is as shown in fig. 1E, and a second image is obtained by rearranging pixels of the raw image data shown in fig. 1C according to a second pixel arrangement manner shown in fig. 1E; the second image is obtained by pixel rearrangement of the inherent pixel points of the photosensitive element, which is equivalent to the fact that the inherent resolution of the photosensitive element is reserved, and the second image can have high resolution and low sensitivity.

In the embodiment, the image resolution to be displayed is set in a user interface mode, so that a user can select the proper image resolution according to the specific requirements of the user, and the photographing experience of the user is improved.

The technical solutions provided by the embodiments of the present disclosure are described below with specific embodiments.

Step S201 can be referred to the description of step S101 in the embodiment shown in fig. 1A, and is not described in detail here.

In step S202, the third resolution input in the prompt box is detected.

In step S203, the size relationship between the third resolution and the first and second resolutions is determined.

In one embodiment, the third resolution may be compared with the first resolution and the second resolution, and the size relationship may exist in the following three cases: the third resolution is greater than or equal to the first resolution and less than or equal to the second resolution, the third resolution being less than the first resolution, the third resolution being greater than the second resolution. When the third resolution is lower than the first resolution, the resolution of the user input is lower than that of the first image, the input is unreasonable, and the user can be prompted to input again; when the third resolution is greater than the first resolution, it indicates that the resolution of the user input is higher than the resolution of the second image, and the input is also unreasonable and may prompt the user to re-enter.

In step S204, the resolution of the image to be displayed is determined based on the size relationship.

In an embodiment, if the size relationship indicates that the third resolution is greater than or equal to the first resolution and the third resolution is less than or equal to the second resolution, it indicates that the resolution input by the user based on the prompt box is reasonable, so the resolution input by the user through the prompt box can be determined as the resolution of the image to be displayed.

In this embodiment, the third resolution of the image to be displayed is determined based on the size relationship between the third resolution and the first resolution, and the second resolution, so that the third resolution of the image to be displayed can be changed along with the perception of the user, and the image to be displayed can be ensured to have better image quality and higher resolution for the user.
