Example

[0070] First embodiment

[0071] In order to enable the terminal to perform light compensation through the front camera or the rear camera when the shooting environment is dark, and to avoid the prone to overexposure or underexposure caused by light compensation by flashing off the light when using the rear camera This embodiment provides a method for close-up shooting. See figure 2 , figure 2 The basic flowchart of a close-range shooting method provided in this embodiment includes:

[0072] S201: Acquire the light intensity of the object to be photographed in the current shooting frame;

[0073] Basically, existing terminals have a perfect light metering mechanism, and the light metering mechanism can detect the light intensity of each point of the object to be photographed in the current shooting frame. In some terminals, the metering capability of the metering mechanism can even reach the level of high-end cameras. It should be understood that in the actual shooting process o...

Example

[0127] Second embodiment

[0128] This embodiment is based on the first embodiment, taking a specific process of light compensation that needs to be performed when a double-sided screen terminal is photographed through a rear camera as an example to further illustrate the present invention.

[0129] Suppose there is a "night scene soft light" mode interface corresponding to the close-up shooting method in the double-sided screen terminal shooting application.

[0130] See Figure 8 As shown, Figure 8 The detailed flowchart of a close-range shooting method provided in this embodiment includes:

[0131] S801: when the user selects the "night scene soft light" mode, obtain the light intensity of the object to be photographed in the current shooting frame;

[0132] S802: When light compensation is required, detect whether the light intensity is greater than the preset second light intensity; if so, the device is in step S803; otherwise, it goes to step S804.

[0133] S803: Control the secon...

Example

[0143] The third embodiment

[0144] This embodiment also provides a terminal, see Picture 9 As shown, it includes a processor 91, a memory 92 and a communication bus 93, where:

[0145] The communication bus 93 is used to implement connection and communication between the processor 91 and the memory 92;

[0146] The processor 91 is configured to execute one or more programs stored in the memory 92 to implement the steps of the close-up shooting method described in the first embodiment and / or the second embodiment.

[0147] It should be understood that the terminal in this embodiment may be a terminal device such as a mobile phone, an iPad, and a computer with a shooting function, and a terminal such as a mobile phone, an iPad, and a computer with a shooting function may have a double-sided screen.

[0148] At the same time, this embodiment also provides a computer-readable storage medium, such as a floppy disk, optical disk, hard disk, flash memory, U disk, CF card, SD card, MMC card...

Abstract

The invention discloses a close-range shooting method, a terminal and a computer readable storage medium. By obtaining the light intensity of an object to be shot in a current shooting frame, when light compensation is needed, a light compensation strategy is determined according to the light intensity, and a display screen on a surface where camera is located is controlled to display the light according to the light compensation strategy. In this way, the light compensation is performed through the display screen on the surface where camera is located, so that exposure compensation can be performed during the shooting of a front camera. For some terminals with display screens on the back surfaces, as the compensation light is from the display screen during the exposure compensation, the displayed light is softer than that of flash light, in this way, the influence to the background environment brightness of the current shooting environment is small, the probability of overexposure orunderexposure is reduced, meanwhile the irritations caused to human eyes are also reduced, the imaging quality is improved, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, and more specifically, to a close-range shooting method, a terminal, and a computer-readable storage medium. Background technique [0002] With the continuous development of terminal technologies, terminals often have an image capturing function. At present, when the terminal is shooting an image, if the current shooting environment is dark, the terminal can only use the set flash to supplement the brightness and perform exposure compensation. However, when the exposure compensation is performed by the flash, since the light emitted by the flash is strong, it is essentially a kind of light compensation by strong light. This makes it have a greater impact on the brightness of the background environment of the current shooting environment, prone to overexposure or underexposure, and affects the final image quality of shooting. At the same time, if the current subject is a person, the ex...
