Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] The embodiment of the present invention provides a camera focusing method. When the camera is detected to be started, the terminal transmits the first ultrasonic signal to the determined subject through the built-in generator, and receives the first ultrasonic signal transmitted to the subject and reflects it back. The second ultrasonic signal, obtain the sending time of the first ultrasonic signal transmitted by the built-in generator, and the r...

Abstract

The embodiment of the invention provides a terminal. The device comprises a signal sending unit for transmitting a first ultrasonic signal to a determined shot object through a built-in generator after detecting a camera is started, a signal receiving unit for receiving a second ultrasonic signal reflected by the first ultrasonic signal transmitted on the shot object, a sending time acquiring unit for acquiring the sending time of the built-in generator transmitting the first ultrasonic signal, a receiving time acquiring unit for acquiring the receiving time of receiving the second ultrasonic signal, a distance acquiring unit for acquiring the distance from the terminal to the shot object according to the time difference between the sending time and the receiving time, and a focusing unit for focusing the camera according to the distance from the terminal to the shot object. With the adoption of the terminal, ultrasonic focusing can be achieved through the built-in generator, thus the shooting effect can be improved, and the photo quality can be increased.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a terminal. Background technique [0002] With the rapid development of electronic technology and image processing technology, the camera function of terminals is becoming more and more powerful. In the process of taking pictures, in order to be able to take better clear pictures, it is necessary to focus, that is, to automatically adjust the position of the lens according to the current scene to achieve the highest clear pictures. The existing focusing method has the problem that the photographing effect is poor in low-contrast and low-light environments, and the quality of the obtained photographs is not high. Contents of the invention [0003] An embodiment of the present invention provides a terminal that can use a built-in generator to implement ultrasonic focusing, thereby improving the effect of taking pictures and improving the quality of the pictures.
