Embodiment 1

[0024] figure 1 A flow chart of the method for adjusting the focus distance of the camera terminal provided by Embodiment 1 of the present invention is given. The method of this embodiment can be executed by the device for adjusting the focus distance of the camera terminal. The device can be implemented by means of hardware and / or software , the device can be set inside the terminal as a part of the terminal having a camera function.

[0025] Such as figure 1 As shown, the method for adjusting the focusing distance of the camera terminal provided in this embodiment specifically includes the following steps:

[0026] Step 101 , regularly monitor the focus distance of the camera terminal by using the distance measuring sensor of the camera terminal.

[0027] Wherein, the terminals include but are not limited to mobile phones, notebooks, PAD smart terminals, tablet computers, digital cameras and other devices.

[0028] The focus distance generally refers to the sum of the dis...

Embodiment 2

[0042] image 3 A flow chart of the method for adjusting the focusing distance of the photographing terminal provided by Embodiment 2 of the present invention is given. This embodiment is optimized on the basis of the first embodiment above, and details not described in detail in this embodiment can be referred to the first embodiment. In this embodiment, judging whether the focus distance satisfies the preset adjustment condition according to the change of the focus distance within the preset time is specifically optimized as follows: obtaining at least one focus distance monitored within the preset time; according to the At least one focus distance is used to determine whether the focus distance satisfies a preset adjustment condition.

[0043] Correspondingly, such as image 3 As shown, the method for adjusting the focusing distance of the camera terminal provided in this embodiment specifically includes the following steps:

[0044] Step 201 , regularly monitor the focu...

Embodiment 3

[0054] Figure 4 A flow chart of the method for adjusting the focus distance of the photographing terminal provided by Embodiment 3 of the present invention is given. This embodiment provides a preferred embodiment based on the second embodiment above. In this embodiment, according to the at least one focus distance, judging whether the focus distance satisfies the preset adjustment condition is specifically optimized as: calculating the average value of the focus distance within the preset time according to the at least one focus distance; Calculating at least one corresponding range of change according to at least one focusing distance and the average value; judging whether the number of the at least one range of change exceeding a first preset threshold reaches a second preset threshold.

[0055] Correspondingly, such as Figure 4 As shown, the method for adjusting the focusing distance of the camera terminal provided in this embodiment specifically includes the following...

Abstract

The embodiment of the invention discloses an adjusting method and device for the focusing distance of a photographing terminal. The method comprises the steps that a distance measuring sensor of the photographing terminal is utilized for monitoring the focusing distance of the photographing terminal in a timing mode; according to changes of the focusing distance within preset time, whether the focusing distance meets a preset adjusting condition or not is judged; when the focusing distance meets the preset adjusting condition, the focusing distance is adjusted; focusing and adjusting are carried out according to the adjusted focusing distance. According to the technical scheme, whether the focusing distance meets the preset adjusting condition or not is judged according to the change conditions of the focusing distance within preset time, only when the focusing distance meets the preset adjusting condition, can the focusing distance be adjusted, otherwise, the focusing distance is not adjusted, the technical problems that in the prior art, as long as the focusing distance changes, the focusing distance is adjusted to carry out focusing again, power consumption of the photographing terminal is large, and the power consumption amount is large are solved, the adjustment technology of an existing photographing terminal to the focusing distance is optimized, and power consumption of the photographing terminal in the photographing process is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of photography, and in particular, to a method and device for adjusting the focusing distance of a photography terminal. Background technique [0002] With the continuous development of electronic technology, digital camera equipment (for example, digital camera or mobile phone with digital camera, etc.) has penetrated into thousands of households, and has become an indispensable tool for everyone to record beautiful natural scenery and engrave the wonderful moments of life. [0003] Because the object may move during the shooting process, resulting in constant changes in the focus distance, in the prior art, the object is constantly refocused when the focus distance changes. This will increase the power consumption of the camera terminal, and the power consumption is relatively serious, seriously affecting the user experience.
