Embodiment 1

[0025] figure 1 It is a schematic flowchart of a photo preview method provided in Embodiment 1 of the present invention. The method provided in this embodiment can be executed by a mobile terminal or a dedicated camera device, which is not limited in this embodiment. For example, figure 1 shown, including:

[0026] Step 101, acquire the remaining power of the device.

[0027] Specifically, for a mobile terminal or a dedicated camera device, a battery management application is usually installed to display the remaining power of the battery in real time. Therefore, the remaining power of the device can be obtained from the battery management application.

[0028] Step 102, according to the remaining power, set the resolution and / or frame rate of the photo preview to the resolution and / or frame rate corresponding to the remaining power.

[0029] Resolution refers to the number of pixels contained in a unit inch, and the resolution determines the fineness of image details. Gene...

Embodiment 2

[0039] figure 2 It is a schematic flowchart of a photo preview method provided by Embodiment 2 of the present invention. The method provided by this embodiment can be executed by terminal equipment, such as mobile terminals such as cameras and mobile phones, such as figure 2 shown, including:

[0040] Step 201, determine the value of the remaining power of the battery.

[0041] When the camera application is started, the value of the remaining power of the current battery can be obtained first, and the value of the remaining power of the current battery can be obtained periodically during the subsequent operation of the camera application, that is, the value of the remaining power of the current battery can be periodically executed. provided method.

[0042] Step 202, according to the value of the remaining power, determine the power level to which the remaining power belongs, query the configuration table, and determine the resolution and frame rate corresponding to the p...

Embodiment 3

[0050] image 3 A schematic structural diagram of a camera preview device provided in Embodiment 3 of the present invention, as shown in image 3 As shown, it includes: an acquisition module 21 , a lowering module 22 and a preview module 23 .

[0051] The acquisition module 21 acquires the remaining power of the device.

[0052] The turn-down module 22 is configured to set the resolution and / or frame rate of the photo preview to the resolution and / or frame rate corresponding to the remaining power according to the remaining power.

[0053] Specifically, the turn-down module 22 is specifically configured to reduce the resolution to the first resolution and / or reduce the frame rate to the first frame rate when the remaining power is lower than the preset threshold.

[0054] The preview module 23 is configured to perform photo preview with the set resolution and / or frame rate.

[0055] Specifically, the preview module 23 is specifically configured to use the set resolution and / o...

Abstract

Embodiments of the present invention provide a photo preview method and device. After obtaining the remaining power of the device, the set resolution and / or frame rate is reduced according to the remaining power, and the adjusted resolution and / or frame rate is adopted For camera preview, since the set resolution and / or frame rate are reduced, the amount of data to be processed is reduced, so the power consumption can be reduced to a certain extent when the device is running, especially when the remaining power is insufficient The available time of the device can be extended, thereby solving the technical problem of high power consumption of camera preview in the prior art.

Description

technical field [0001] The invention relates to information technology, in particular to a method and device for previewing photos. Background technique [0002] With the continuous development of science and technology, the function of taking pictures can not only be realized by special camera equipment, but also in mobile terminals such as mobile phones, the camera application is also an application program commonly used by users. With this application, users can also take pictures. In the camera application of the camera device or the mobile terminal, the image currently collected by the lens can be displayed in real time, so that the user can preview the effect of taking pictures. [0003] In the process of realizing the present invention, the inventor finds that the prior art has the following defects: [0004] The photo preview takes up a lot of power because it needs to collect and display images in real time. Especially when the remaining power is insufficient, th...
