Embodiment 1

[0023] figure 1 It is a schematic flowchart of a method for quickly starting a camera of a mobile terminal provided by Embodiment 1 of the present invention. The method is applicable to the situation of starting the camera in the mobile terminal, and can be executed by a device for quickly starting the camera of the mobile terminal, wherein the device can be implemented by software and / or hardware, and is generally integrated in the mobile terminal.

[0024] Specifically, such as figure 1 As shown, a method for quickly starting a mobile terminal camera provided by Embodiment 1 of the present invention includes the following operations:

[0025] Step S101, after receiving the mobile terminal camera startup request, read the memory allocation information saved in the specified file.

[0026] Step S102. Allocate the memory space pointed to in the memory allocation information to the camera for image data caching.

[0027] In the above operation steps of this embodiment, the mo...

Embodiment 2

[0034] figure 2It is a schematic flowchart of a method for quickly starting a camera of a mobile terminal provided by Embodiment 2 of the present invention. Embodiment 2 of the present invention is based on the above-mentioned embodiments, and further, the step "after receiving the mobile terminal camera startup request, read the memory allocation information stored in the specified file" is specifically optimized as follows: after receiving the camera startup request Afterwards, detecting whether the content stored in the specified file is empty; if the content stored in the specified file is not empty, then read the memory allocation information stored in the specified file. In addition, further optimization includes: after receiving the request for starting the camera, after detecting whether the content stored in the specified file is empty, if the content stored in the specified file is empty, then for the mobile terminal camera The image data is allocated for the appli...

Embodiment 3

[0053] image 3 It is a schematic flowchart of a method for quickly starting a camera of a mobile terminal provided by an embodiment of the present invention. Embodiment 3 of the present invention is based on the above embodiments. In this embodiment, before receiving the mobile terminal camera startup request, it also includes: when the specified file does not exist, setting a static vector table as the specified file , and initialize the specified file to be empty to store the memory allocation information.

[0054] In addition, the second embodiment of the present invention further preferably includes: releasing the memory space for caching the image data and deleting the specified file when it is detected that the mobile terminal is powered off or restarted.

[0055] Such as image 3 As shown, a method for quickly starting a mobile terminal camera provided by Embodiment 3 of the present invention specifically includes the following operations:

[0056] Step S301. When t...

Abstract

The invention discloses a method and device for rapidly starting a mobile terminal camera and a mobile terminal.The method for rapidly starting the mobile terminal camera includes the steps that after a mobile terminal camera starting request is received, memory allocation information stored in a specific file is read; memory space designated in the memory allocation information is allocated to the camera for caching image data.By means of the method, the operation of allocating the image data of the mobile terminal camera when the camera is started is omitted, namely, the operation of repeatedly applying for and allocating the memory space for caching the image data of the camera every time when the camera starting request is received is omitted, so that the time of 60 ms-80 ms for allocating and applying for the memory space for the image data is saved, starting of the mobile terminal camera is accelerated, and time consumption of starting of the camera is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile terminals, and in particular, to a method and device for quickly starting a camera of a mobile terminal, and a mobile terminal. Background technique [0002] The camera is a very important function in mobile devices such as mobile phones and tablet computers, and for users who like to capture beautiful moments, the startup speed of the camera is very important. However, based on the current camera start-up process, it can be seen that after receiving the mobile terminal camera start-up request, it is first necessary to configure the image data of the camera for the camera, so as to apply for and allocate corresponding cache space for the image data when the camera takes pictures, and then Only then can the camera be started to enter the display interface for taking pictures, to preview pictures or take pictures based on the camera. [0003] Generally speaking, configuring the...
