Embodiment Construction
[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0035] Refer to figure 1 , Is a test method of camera anti-shake performance, including:
[0036] S110. Place the mobile phone to be tested in a test box, wherein the test box has a vibration device that vibrates the mobile phone to be tested and a test board located within the shooting range of the camera of the mobile phone to be tested. The test board has a test image on the side facing the mobile phone.
[0037] S120. Connect a computer to the mobile phone to be tested.
[0038] S130. When the vibration device vibrates the mobile phone under test, the computer sends a test instruction to mak...

The invention relates to a testing method of anti-shaking performance of a camera. The method comprises the following steps: a to-be-tested mobile phone is placed in a testing box, wherein a vibrationdevice for enabling the to-be-tested mobile phone to vibrate and a testing board located in a shooting range of the camera of the to-be-tested camera are arranged in the testing box, and a testing image is formed on one surface of the testing board facing the mobile phone; a computer is connected to the to-be-tested mobile phone; the computer sends a testing instruction when the vibrating devicevibrates the to-be-tested mobile phone, thereby enabling the to-be-tested mobile phone to shoot the testing image of the testing board under the state of turning on the anti-shaking function of the mobile phone to obtain a first testing image; the computer sends the testing instruction when the vibrating device vibrates the to-be-tested mobile phone, thereby enabling the to-be-tested mobile phoneto shoot the testing image of the testing board under the state of turning off the anti-shaking function of the mobile phone to obtain a second testing image. The testing method disclosed by the invention is high in testing accuracy, high in testing efficiency and high in testing accuracy, and the testing labor cost is greatly saved.
Description
Technical field [0001] The invention relates to the technical field of mobile phone testing, in particular to a method for testing the anti-shake performance of a camera. Background technique [0002] More and more cameras have anti-shake function. There are usually two methods for anti-shake: [0003] Optical image stabilization [0004] When the hand shakes, the detection circuit detects the direction of the shake, and the control circuit controls the PSD lens to move accordingly to compensate for the shake. This method has a good compensation effect and no picture loss after compensation, but the circuit and optical structure are complex and the cost is relatively high. Generally, only high-end 3CCD cameras are equipped. [0005] The CCD image stabilization used by some brands is actually another form of optical image stabilization. The principle is to place the CCD on a bracket that can move up and down, left and right, and first detect whether there is jitter. Because of the us...
