Abstract

The invention discloses an automatic test system of a reproduction ratio. The automatic test system of the reproduction ratio comprises a test terminal, a signal resource generator and an image collector. The test terminal is used for issuing a channel switching order to a to-be-tested display device to control the display device to be switched to a signal channel which needs to be tested. The signal resource generator is used for outputting reference image signals to the display device. The image collector is used for collecting the actual displayed image of the display device after the reference image signals are received, and transmitting the actual displayed image to the test terminal. The test terminal is further used for receiving the actual displayer image, and calculating according to the actual displayed image and a local preservation reference image to obtain the reproduction ratio of the display device. The automatic test system of the reproduction ratio can improve the test accuracy of the reproduction ratio of the display device, and test efficiency is high.

Description

technical field [0001] The invention relates to the technical field of image testing, in particular to an automatic testing system for a redisplay rate. Background technique [0002] Redisplay rate is an important indicator of TV image testing. It refers to the ratio of the image program reproduced on the TV screen to the image program sent by the TV station. It is divided into vertical redisplay rate and horizontal redisplay rate. For example, the horizontal effective image pixels are 720, but 680 pixels are actually displayed, then the horizontal redisplay rate is 680 / 720. [0003] In the TV, it is often encountered that different customers have different requirements for the display rate, and different TV signals will also require different display rates to be displayed, so testing and debugging the display rate becomes a regular task. repeated work. In the prior art, an image with a scale is mainly used as an image for testing and displayed on a TV screen. Then manual...
