Problems solved by technology

However, in a dark environment, in order to ensure the quality of the photo, the camera will generally use a lower frame rate to take pictures, and the auto focus will also focus at this lower frame rate, resulting in a very slow focusing speed

Embodiment Construction

[0041] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements. The method for improving the focus speed of the camera based on the mobile terminal of the present invention will rapidly increase the frame rate of the camera after receiving the focus command when the ambient brightness is low, and focus at a larger focus frame rate. After the focus is completed, the frame before the focus is restored The rate achieves fast focusing and the user experience is better.

[0042] Please refer to figure 1 , the present invention is based on the method for improving camera focusing speed of mobile terminal and comprises the following steps:

[0043] Step S101, receiving a focus command issued by the upper layer;

[0044] Step S102, detecting the frame rate of the camera under the current ambient brightness, recording the frame rate as the current frame rate, such as the current frame rate is ...

Abstract

The invention discloses a method for increasing the focusing speed of a camera based on a mobile terminal. The method includes the steps that a focusing instruction is received; whether the current frame rate of the camera is smaller than a set frame rate or not is detected and judged; when the judgment result is yes, the focusing frame rate larger than the current frame rate is acquired; according to the focusing frame rate, focusing is completed. Compared with the prior art, after the mobile terminal receives the focusing instruction, firstly, whether the current frame rate of the camera is smaller than the set frame rate or not is detected and judged, then, when the judgment result is yes, the focusing frame rate larger than the current frame rate is acquired, finally, according to the focusing frame rate, focusing is completed, and therefore in the focusing process when the ambient brightness is low (when the current frame rate is smaller than the set frame rate), focusing is performed through the large focusing frame rate instead of the low focusing frame rate, the focusing speed is high, and user experience is good. The invention further discloses the mobile terminal for increasing the focusing speed of the camera.

Description

technical field [0001] The present invention relates to the field of photography, and more specifically relates to a mobile terminal-based method for improving the focusing speed of a camera and a mobile terminal thereof. Background technique [0002] At present, except that the camera has a shooting function, cameras have been installed on most mobile terminals to realize the shooting function. A camera or a camera unit on a mobile terminal generally has an auto-focus function, so that the shooting scene can be focused during image preview. However, in a dark environment, in order to ensure the quality of the photo, the camera generally uses a lower frame rate to take pictures, and the autofocus also uses this lower frame rate to focus, resulting in a very slow focusing speed. Contents of the invention [0003] The purpose of the present invention is to provide a mobile terminal-based method for improving the focusing speed of a camera, so as to achieve fast focusing in ...
