Automatic detection system and detection method for mobile phone camera

Abstract

Disclosed is an automatic detection system for a mobile phone camera. The system comprises a test clamp module for placing a mobile phone; a signal feedback device for leading out a test result; a control unit which is electrically connected with the test clamp module through a test control line so as to control a test to start or end and output whether the test result is qualified and is eclectically connected with the mobile phone through a shooting control line so as to send a shooting instruction and feed a shot test image; and a test cart card module which is opposite to the test clamp module for shooting and comparison of the camera. The mobile phone is placed on the test clamp module, a control interface module sends a signal to be detected to the control unit, the control unit sends a test starting instruction to the mobile phone through the shooting control line so as to drive the mobile phone to start a test, after the test card chart module is shot, the mobile phone transmits a detected image to the control unit through the shooting control line for comparison calibration, and the control unit, according to a comparison analysis result, gives a feedback to a signal feedback device so as to output and display whether the test result is qualified.

Description

Technical field [0001] The invention relates to the field of mobile phone testing, in particular to an automatic detection system and a detection method used for a mobile phone camera. Background technique [0002] With the rapid development of mobile communication technology, consumers have higher and higher requirements for mobile terminals. Manufacturers have put forward their own characteristic selling points, including improving the camera shooting effect of mobile terminals. There are many kinds of mobile terminals, including mobile phones, tablet computers, video phones, car navigators, etc. Among them, smart phones pay more attention to the camera shooting effect. In the factory manufacturing process, the addition of camera detection tests can ensure the shooting quality of the mobile terminal. However, as the scale of mobile terminal manufacturing becomes larger and larger, the cost of human resources is getting higher and higher. Only by reducing the cost of testing a...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing mobile phone camera detects the images taken by manually holding the mobile phone, and then manually judges whether the captured images are clear or not. The inconsistency of the captured images due to hand shaking can easily lead to misjudgment. This kind of judgment method is highly subjective and easy to make mistakes Judgment, low production efficiency

[0005] 2. Existing mobile phone camera detection adopts subjective judgment of whether the image is clear by shooting a single picture card. During the detection process, the picture card needs to be changed according to the detected items. This judgment method is highly subjective, easy to misjudgment, and low in production efficiency.

[0006] 3. Existing mobile phone camera detection cannot quantify the color distribution and grayscale changes of the picture through the detection equipment, and cannot save the detection data for analysis by technicians

[0007] 4. The existing mobile phone camera detection equipment is a single device that does not use a powerful computer for system connection, and cannot effectively carry out factory manufacturing execution management
