Problems solved by technology

But in fact, most users are not professional photographers. These users will inevitably shake when holding mobile terminals, and each person's body control ability is different. It is easy to use a fixed system security shutter time when taking pictures. Blurred, not suitable for every user's usage habits

Embodiment 1

[0021] figure 1 It is a flow chart of a method for setting a safe shutter time provided by Embodiment 1 of the present invention. This embodiment is applicable to setting the safe shutter time according to the user's habitual operation. This method can be executed by a mobile terminal, and specifically includes the following steps :

[0022] Step 110, when it is detected that the camera function is turned on, acquiring and recording the shaking data of the mobile terminal at intervals of a first set time.

[0023] When a user holds a mobile terminal to take a photo, the hand holding the mobile terminal will shake to a certain extent, causing the mobile terminal to shake accordingly. Due to the different operating habits of each person, when each person takes a photo, the shaking amplitude of the mobile terminal also varies. Different, this will lead to the use of the same system security shutter time is not suitable for every user, the embodiment of the present invention is t...

Embodiment 2

[0047] figure 2 It is a flow chart of a method for setting a safe shutter time provided by Embodiment 2 of the present invention. This embodiment optimizes Embodiment 1, and acquires and records the first interval setting time of the mobile terminal in Embodiment 1. The jitter data optimization is to acquire the jitter data of the mobile terminal at intervals of a first set time, and record the jitter data when the jitter amplitude in the jitter data is within a set range. Specifically include the following steps:

[0048] Step 210, when it is detected that the camera function is turned on, acquiring shaking data of the mobile terminal at intervals of a first set time.

[0049] When the mobile terminal detects that the camera function is turned on, the shake data of the mobile terminal is acquired once and recorded, and then the shake data of the mobile terminal is acquired once every first set time and the acquired shake data is recorded. The jitter data includes jitter time...

Embodiment 3

[0058] image 3 It is a schematic structural diagram of a safety shutter time setting device provided in Embodiment 3 of the present invention, as shown in image 3 As shown, the device for setting the safe shutter time in this embodiment includes: a jitter data acquisition module 310, an average speed calculation module 320, a jitter time calculation module 330 and a shutter time setting module 340.

[0059] Wherein, the jitter data acquisition module 310 is used to acquire and record the jitter data of the mobile terminal at intervals of the first set time when it is detected that the camera function is turned on;

[0060] The average speed statistics module 320 is used to count the average movement speed of the mobile terminal within the second set time according to the jitter data;

[0061] The shaking time calculation module 330 is used to calculate the shaking time of the mobile terminal according to the average motion speed and the set offset;

[0062] The shutter tim...

Abstract

The invention discloses a method for setting safety shutter time, a device and a mobile terminal. The method comprises the following steps: acquiring and recording shaking data of the mobile terminal at an interval of the first preset time when the starting of shooting function is detected; statistically recording an average moving speed of the mobile terminal within the second preset time according to the shaking data; calculating the shaking time of the mobile terminal according to the average moving speed and the preset offset; setting the shaking time as the safety shutter time. According to the method provided by the invention, the safety shutter time is set according to the shaking data formed by the use habit of the user, the photos shot at the safety shutter time are prevented from being dim and the photos are clear.

Description

technical field [0001] Embodiments of the present invention relate to imaging technology, and in particular to a method, device and mobile terminal for setting a safe shutter time. Background technique [0002] In the prior art, in the setting of the safe shutter time, the mobile terminal fixes a system safe shutter time as the highest safe shutter time value of the system. No matter what the light is, the exposure time will not exceed this shutter time length. This method theoretically ensures that most users are not easy to blur when taking pictures. [0003] In the photography world, photographers with stable hands are often called iron hands, because they hold mobile terminals and other mobile devices with cameras more stably when taking pictures. But in fact, most users are not professional photographers. These users will inevitably shake when holding mobile terminals, and each person's body control ability is different. It is easy to use a fixed system security shutte...
