specific Embodiment approach 1

[0066] Embodiment 1. In this embodiment, only the ratio of the first area of ​​the initial ROI to the second area of ​​the real-time ROI and the initial zoom ratio are used to adjust the zoom ratio of the real-time shooting preview interface so that the first ratio and the second ratio Consistently, the method steps of the automatic focus tracking and focusing method for shooting a moving object provided in this specific embodiment include:

[0067] Step 201, after starting to click on the recording control, obtain the initial ROI and the initial zoom ratio (zoom ratio) of the current shooting preview interface; wherein, the ROI includes the target moving object;

[0068] Step 202, save the first area of ​​the initial ROI, and determine the current shooting preview interface according to the ratio of the first area of ​​the initial ROI to the second area of ​​the returned real-time ROI when the target moving object continues to move far away real-time zoom ratio;

[0069] Tha...

specific Embodiment approach 2

[0072] Embodiment 2. On the basis of Embodiment 1 above, this embodiment combines the distance value between the moving object and the terminal to further determine the real-time zoom ratio. The specific steps of the method for automatically focusing and shooting the moving object include:

[0073] Step 301, when the user clicks on the recording control, the user can manually determine the area to be selected;

[0074] Among them, the user can select a fixed point by double-clicking, and then the user can realize the effect of stretching by clicking on the point and moving to the lower right corner to determine the display frame of self-selected stretching, that is, the area to be selected.

[0075] Step 302, when the selected area is determined, turn on the laser ranging camera;

[0076] Step 303, according to the detection area selected by the user, obtain the first area of ​​the corresponding initial ROI and the initial zoom ratio; at this time, it is also possible to choos...

Abstract

The invention discloses a shooting method and device, electronic equipment and a readable storage medium, and belongs to the field of photography. The method comprises the steps of obtaining a first area of an initial area of interest ROI in a shooting preview interface and an initial zoom ratio of the shooting preview interface; under the condition that the relative position of the target moving object relative to the target camera is changed, obtaining a second area of a real-time ROI of the shooting preview interface; adjusting the real-time zoom magnification of the shooting preview interface according to the ratio of the first area to the second area and the initial zoom magnification, so as to enable the first proportion to be the same as the second proportion; wherein the first proportion is the proportion of the target moving object in the shooting preview interface after the relative position is changed, and the second proportion is the proportion of the target moving object in the shooting preview interface before the relative position is changed. According to the invention, the problem in the prior art that a user needs to manually switch the multiplying power if the size of a moving object in a camera shooting picture needs to be kept constant is solved.

Description

technical field [0001] The present application belongs to the field of photography, and in particular relates to a photography method, device, electronic equipment and readable storage medium. Background technique [0002] At present, when a user shoots a moving object, it usually shoots through the same camera device. Therefore, the user needs to constantly adjust the zoom ratio of the display screen, and manually increase the zoom ratio of the screen according to the distance of the object from the mobile phone, so as to achieve the clear visibility of the object in the display screen and maintain the constant size of the moving object in the camera screen. However, it is cumbersome to manually switch the magnification. Contents of the invention [0003] The purpose of the embodiment of the present application is to provide a shooting method, device, electronic equipment and readable storage medium, which can solve the problem in the prior art that if the size of the mo...
