Embodiment 1

[0049] This embodiment provides a control method for switching between camera modules, where the camera module may be a camera module in a mobile terminal (for example, a mobile phone).

[0050] Such as figure 1 As shown, the control method may include the following steps:

[0051] Step S10: Obtain the first brightness parameter of the image captured by the current camera module;

[0052] The first brightness parameter includes an image brightness value and / or a pixel value of each pixel point in the image, where the image brightness value may be the result of dividing the captured image into a plurality of small area images, and each small area image Each has a brightness value, and the image brightness value can be represented by a bit value. The image brightness value can be calculated by AE (camera automatic exposure control algorithm).

[0053] Step S11: receiving the zoom ratio adjustment command and detecting the current zoom ratio of the current camera module in real ...

Embodiment 2

[0066] This embodiment provides a control method for camera module switching, which is a further improvement on the basis of Embodiment 1. Specifically, the control method may further include:

[0067] Controlling the current camera module and the camera module to be switched to be turned on simultaneously and run independently at the same time. Specifically, all the camera modules may be started simultaneously when starting up, or other camera modules may be controlled to be started simultaneously when it is detected that a user actively starts one of the camera modules.

[0068] In this case, the current camera module can run in the foreground of the mobile phone, and one or more camera modules to be switched can simultaneously run in the background of the mobile phone, and can control the frame rate of the camera modules to be switched running in the background (that is, every The number of displayed frames per second) is below the preset frame rate threshold to reduce the ...

Embodiment 3

[0074] This embodiment provides a control system for camera module switching, such as image 3 As shown, the control system 1 may include:

[0075] Brightness parameter obtaining module 11, is used for obtaining the first brightness parameter of the image taken by current camera module;

[0076] The first brightness parameter includes an image brightness value and / or a pixel value of each pixel point in the image, where the image brightness value may be the result of dividing the captured image into a plurality of small area images, and each small area image Each has a brightness value, and the image brightness value can be represented by a bit value. The image brightness value can be calculated by AE (camera automatic exposure control algorithm).

[0077] The zoom ratio detection module 12 is used to receive the zoom ratio adjustment instruction and detect the current zoom ratio of the current camera module in real time;

[0078] The adjustment module 13 is used to adjust ...

Abstract

The invention discloses a camera module switching control method and system, a medium and electronic equipment. The control method comprises the following steps: acquiring a first brightness parameterof an image shot by a current camera module; receiving a zoom ratio adjustment instruction and detecting the current zoom ratio of the current camera module in real time; if the deviation between thecurrent zoom ratio and the critical optical zoom ratio is smaller than a first preset threshold value, adjusting a second brightness parameter of imaging of a to-be-switched camera module according to the first brightness parameter so as to enable the second brightness parameter to be consistent with the first brightness parameter; and when the current zoom ratio is equal to the critical opticalzoom ratio, switching the current camera module to the to-be-switched camera module. According to the scheme, the problem of sudden brightness change caused by switching of a plurality of camera modules in any scene is solved, the cost is effectively reduced, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of mobile phone cameras, in particular to a camera module switching control method, system, medium and electronic equipment. Background technique [0002] When the mobile phone camera is zooming, there will be sudden changes in brightness and contrast at the moment of switching between cameras with different focal lengths and FOVs (field of view), thereby affecting the user experience of the mobile phone camera in use. [0003] In the prior art, a static synchronization scheme and a dynamic synchronization scheme are usually adopted to solve sudden changes in brightness and contrast that occur during the switching process of different camera modules. [0004] For the static synchronization solution, it is necessary to burn the photosensitivity of different camera modules into the OTP (one-time programmable component), and then perform brightness synchronization by multiplying by a fixed gain. Since the stat...
