Embodiment 1

[0041] Based on the foregoing embodiments, this embodiment provides a photographing method, the executive subject of the photographing method is a mobile terminal, and at least one image acquisition module is arranged in the mobile terminal, and image acquisition can be performed through the image acquisition module to obtain images .

[0042] In practical applications, the above-mentioned image acquisition module can be a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS) image sensing unit, or a charge-coupled device (CCD) image sensing unit, of course, it can also be Other types of image sensing units. Here, the embodiment of the present invention does not specifically limit it.

[0043] In practical applications, the mobile terminal can be an electronic device with a camera function such as a smart phone, a tablet computer, a digital camera, etc. with a front camera or a rear camera or a specific front and rear camera at the same time....

Embodiment 2

[0130] Based on the foregoing embodiments, this embodiment provides a photographing method, which is applied to the following scenarios: adaptively select a method for determining exposure parameters correspondingly according to the photographing mode of the mobile terminal, so as to determine more appropriate exposure parameters.

[0131] So, Figure 5 It is a schematic flow chart of the photographing method in Embodiment 2 of the present invention, see Figure 5 As shown, the method includes:

[0132] S501: Obtain a photographing instruction;

[0133] S502: Execute the photographing instruction, and measure the light intensity value of the scene to be photographed by the mobile terminal based on the preset exposure parameters;

[0134] S503: Find and obtain the original exposure value corresponding to the light intensity value based on the pre-stored mapping relationship between the light intensity value and the exposure value;

[0135] S504: Comparing the light intensity...

Embodiment 3

[0152] Based on the same inventive concept, this embodiment provides a photographing device, which is applied to the above one or more mobile terminals.

[0153] So, Figure 6 It is a schematic structural diagram of the camera device in Embodiment 3 of the present invention, see Figure 6 As shown, the photographing device 60 includes: a memory 601, a processor 602, and a computer program 603 stored on the memory 601 and operable on the processor 602. When the processor 602 executes the computer program 603, the following steps are implemented: obtaining a photographing instruction; Execute the photographing instruction, based on the preset exposure parameters, measure the light intensity value of the scene to be photographed by the mobile terminal; according to the preset strategy, determine the first exposure parameter and the second exposure parameter corresponding to the light intensity value, wherein the second exposure The parameter is different from the first exposure ...

Abstract

The embodiment of the invention discloses a photographing method which is applied to a mobile terminal. The method comprises the steps that a photographing instruction is acquired; the photographing instruction is performed, and the light intensity value of the scene to be photographed by the mobile terminal is measured based on the preset exposure parameter; a first exposure parameter and a second exposure parameter corresponding to the light intensity value are determined according to the preset strategy, wherein the second exposure parameter is different from the first exposure parameter; image acquisition is performed based on the first exposure parameter so as to acquire a preview image, and the preview image is previewed; and photographing is performed based on the second exposure parameter after previewing of the preview image is completed. The embodiment of the invention also discloses photographing equipment and a computer readable storage medium.

Description

technical field [0001] The present invention relates to the field of electronic equipment, in particular to a photographing method, equipment and computer-readable storage medium. Background technique [0002] With the continuous development of science and technology and electronic equipment, mobile terminals have become a necessity in people's daily life, and taking pictures is a very important function for current mobile terminals such as smart phones, tablet computers, etc., so that people can enjoy The convenience brought by the development of science and technology. [0003] Currently, when a user uses a mobile terminal to take pictures, the preview exposure time is the same as the shooting exposure time. In this way, when the external light is relatively dark, such as night scenes, rainy days, dark light environments, etc., if the exposure time is shorter, although the preview speed and focusing speed are faster, the noise in the obtained image will be greater. resul...
