Abstract

The invention relates to a detecting instrument of a mobile phone lens, in particular to a mobile phone focus-fixed image quality detector. The mobile phone focus-fixed image quality detector comprises a rack and also comprises a testing graph card group including a near-focus testing graph card and a far-focus testing graph card located on the rack, a teleconverter lens group, an illumination light source for emitting and irradiating uniform light to the testing graph card group, and a mobile carrier capable of driving a mobile phone to be detected to move on the rack, wherein the testing graph card group, the teleconverter lens group is opposite to the far-focus testing graph card, the near-focus testing graph card and the far-focus testing graph card are installed on the rack, and the mobile phone to be detected moves on the two graph cards through the mobile carrier to achieve switching of near-focus and far-focus tests. In addition, the teleconverter lens group is added on the rack and is utilized to make the imaging distance of the far-focus testing graph card greater than the actual distance from the mobile phone to be detected to the far-focus testing graph card so as to simulate far-distance shooting, the size of the detecting instrument can be greatly decreased, and accordingly the detecting efficiency is effectively improved.

Description

【Technical field】 [0001] The application relates to a testing instrument for a mobile phone lens, in particular to a fixed-focus image quality testing instrument for a mobile phone. 【Background technique】 [0002] Mobile phone lens detection is an important indicator of mobile phone performance testing. Usually, close-focus shooting detection and far-focus shooting detection are required to verify the focus sensitivity and resolution of the mobile phone lens, and the distance of far-focus shooting detection needs to be more than 2 meters. A large test space is required, and some existing detectors use CHART to move to a far place after shooting close focus to perform far focus testing, which is not only inefficient, but also makes the detection instrument complex in structure and large in size. 【Content of invention】 [0003] In order to solve the problem of low detection efficiency due to the large space required for mobile phone lens detection in the prior art, the appli...
