Embodiment Construction

[0057] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0058] Aiming at the problems of uncertainty and low repeatability in testing the image transmitted by the camera through the camera data acquisition interface when testing the application multimedia processor chip in the prior art, the embodiment of the present invention provides a chip camera interface The function test method and device generate a fixed test image to simulate the image collected by the camera to ensure the certainty and repeatability of the test image. When testing the application multimedia processor chip, the test image is used to replace the image collected by the actual camera and input to the camera interface of the chip to realize the functional test of the chip, which not only avoids th...

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...
