Chip camera interface function testing method and chip camera interface function testing system

Abstract

The invention relates to the technical field of chip tests, and discloses a chip camera interface function testing method and a chip camera interface function testing system. The method includes the following steps: simulating a camera interface signal to generate a test image; and inputting the test image into a chip camera interface, and carrying out a chip function test. The invention can be utilized to increase the accuracy and automation degree of tests and the repeatability of a testing process.

Description

technical field [0001] The invention relates to the technical field of chip testing, and more specifically, to a chip camera interface function testing method and device. Background technique [0002] Chip testing is a necessary link to ensure chip functions. During the testing process of multimedia processor chips, the BBT (Bench Board Test, Console Test) verification of some modules means that the chip is basically tested on a platform close to the actual use environment. The simulation test of the function requires people to make subjective judgments on the test results. For example, the chip is designed with a camera interface to receive the image data sent by the camera, but the image data captured by the camera is not fixed. If the human eye judges, It can only be judged by converting the image data captured by the camera into pictures or displaying them on the screen. Image acquisition through the camera will be affected by uncertain factors such as ambient light and...

[0002] Chip testing is a necessary link to ensure chip functions. During the testing process of multimedia processor chips, the BBT (Bench Board Test, Console Test) verification of some modules means that the chip is basically tested on a platform close to the actual use environment. The simulation test of the function requires people to make subjective judgments on the test results. For example, the chip is designed with a camera interface to receive the image data sent by the camera, but the image data captured by the camera is not fixed. If the human eye judges, It can only be judged by converting the image data captured by the camera into a picture or displaying it on the screen

Image acquisition through the camera will be affected by uncertain factors such as ambient light and noise. The acquired results are not accurate and have low repeatability, which is not conducive to automatic image recognition by software and judgment on image quality.

In addition, the camera equipment on the market has a fixed range of data collection speed, because it is limited by the actual situation, it is impossible to achieve a high speed
