Problems solved by technology

[0003] However, imitating the anti-shake design of a digital camera will not only greatly increase the technical cost of the mobile phone, but also the size of the mobile phone will largely limit the technical application of the digital camera, so that the anti-shake effect of the mobile phone is always unsatisfactory.
[0004] Therefore, the existing technology still needs to be improved and developed

Embodiment Construction

[0035] The method of the present invention and the specific implementations and examples of the mobile phone will be described in detail below in conjunction with the accompanying drawings.

[0036] An anti-shake method for a mobile phone in taking pictures according to the present invention, one of its specific implementations is as attached figure 1 shown, including the following steps:

[0037] Step S101, pressing the shutter of the camera on the mobile phone;

[0038] Step S102, entering the early stage of taking pictures, the gravity sensor (g-sensor) on the mobile phone detects the degree of shaking when taking pictures and determines the level of shaking; the so-called early stage of taking pictures refers to the time period before the exposure of taking pictures after the shutter is pressed;

[0039] Step S103, the camera controls the exposure time according to the shake level;

[0040] Steps S104a and S104b, on the one hand, the camera takes pictures according to th...

Abstract

The invention discloses a camera cellphone with a tremble prevention function and a tremble prevention method in photographing process thereof. The method comprises the following steps of detecting a tremble level when photographing a cellphone through a gravity sensor on the cellphone; controlling the exposure time of the cellphone in the photographing process according to the detected tremble level and photographing by a camera module on the cellphone according to the exposure time; and carrying out sharp processing on a fuzzy image by utilizing an image treatment software program combining with a displacement vector generated by tremble. Because a g-sensor gravity sensor and an image after treatment technology are adopted, the exposure time is controlled according to the tremble level detected when the cellphone is used for taking the photograph so as to realize first tremble prevention; and the displacement vector of the tremble is utilized to compensate the fuzzy image so as to realize second tremble prevention; therefore, a photographing function with ideal tremble prevention effect is realized on the cellphone with low cost and is particularly suitable for being used on an intelligent cellphone with a high end g-sensor gravity sensor.

Description

technical field [0001] The invention relates to the field of a mobile phone with a camera function and an anti-shake method in the process of taking pictures. More specifically, the improvement relates to a camera phone with an anti-shake function and an anti-shake method in the process of taking pictures. Background technique [0002] With the popularization and application of the camera function on mobile phones, people will also use mobile phones to take pictures more and more; like digital cameras, there is also the problem of how to prevent shaking when using mobile phones to take pictures. [0003] However, imitating the anti-shake design of a digital camera will not only greatly increase the technical cost of the mobile phone, but also the size of the mobile phone will largely limit the technical application of the digital camera, so that the anti-shake effect of the mobile phone is always unsatisfactory. [0004] Therefore, the prior art still needs to be improved an...
