Problems solved by technology

[0003] The current mobile terminals all have a long exposure function, but the long exposure function has a defect, that is, under normal light brightness, the photos taken must be overexposed, which reduces the playability
The use of light reduction film accessories can solve this problem, but it will increase the cost of the product

Embodiment 1

[0021] figure 1 It is a schematic flowchart of an image capturing method provided in Embodiment 1 of the present invention. The method can be executed by an image capturing device configured in a mobile terminal, and the device can be implemented in the form of hardware and / or software.

[0022] The method includes:

[0023] S110. In the multiple exposure mode, obtain the shooting duration;

[0024] In the technical solution of this embodiment, a multiple exposure mode is set for the terminal. In this mode, the shooting duration is first obtained. Specifically, the user can input and set the shooting duration, or several preset shooting durations can be selected by the user, or is the default appropriate shooting time. The shooting duration refers to the time that the subsequent shooting process should last.

[0025] S120. After the user inputs the shooting instruction, continuously shoot at least two images within the shooting duration according to the frame rate of the sh...

Embodiment 2

[0032] figure 2 It is a schematic flowchart of an image capturing method provided by an embodiment of the present invention. The technical solution of this embodiment is based on Embodiment 1. Further, before obtaining the shooting duration, it further includes: identifying the current light state, and enabling the multiple exposure mode when the current light state meets the set condition. That is, the terminal can automatically sense the light conditions and switch to the long-exposure shooting mode to avoid overexposure.

[0033] Further, the current light state will be identified, and when the current light state reaches the set condition, the operation of opening the multiple exposure mode is optimized as follows: obtaining the automatic sensitivity of the imaging device, when the automatic sensitivity is lower than the set When the threshold value is reached, it is determined that the current light state meets the set condition, and the multiple exposure mode is turned...

Embodiment 3

[0043] image 3 It is a schematic flowchart of an image capturing method provided by an embodiment of the present invention. The technical solution of this embodiment is based on the above embodiment, and further, the at least two images are superimposed to form the optimization of the shooting image operation as follows: calculate the adjusted saturation and adjusted brightness of each image according to the formula ; for superimposing the adjusted saturation and adjusted brightness of the corresponding pixels of the at least two images to form the saturation and brightness of the corresponding pixels of the captured image.

[0044] Based on the optimized operation, the method provided in this embodiment includes the following steps:

[0045] S310. In the multiple exposure mode, obtain the shooting duration;

[0046] S320. After the user inputs the shooting instruction, continuously shoot at least two images within the shooting duration according to the frame rate of the sh...

Abstract

The invention discloses an image shooting method and device. The method includes: in the multiple exposure mode, acquiring the shooting duration; after the user inputs the shooting instruction, continuously shooting at least two images within the shooting duration according to the frame rate of the shooting device; superimposing the at least two images , to form the captured image this time. The image capturing method and device provided by the embodiments of the present invention can conveniently avoid the overexposure problem of long-exposure images and improve image quality.

Description

technical field [0001] Embodiments of the present invention relate to image data processing technologies, and in particular, to an image capturing method and device. Background technique [0002] With the development of science and technology, it has become a commonly used function for people to take pictures by using a mobile terminal. [0003] The current mobile terminals all have a long exposure function, but the long exposure function has a defect, that is, under normal light brightness, the photos taken must be overexposed, which reduces the playability. An accessory using a light reduction film can solve this problem, but it will increase the cost of the product. Contents of the invention [0004] Embodiments of the present invention provide an image capturing method and device, so as to improve image quality and greatly increase user value. [0005] In a first aspect, an embodiment of the present invention provides an image capturing method, the method comprising:...
