Description

Chip test light source calibration device

Technical Field

The utility model relates to the field of CMOS image sensing chip test light sources, in particular to a chip test light source calibration device.

Background

When the existing chip (image sensor) is tested, a light source is added in the test environment to simulate the working state of the chip in white light, dark light and color light environments. The current test environment has no consistent standard for the standard of the light source, the test standard mainly comes from the judgment of the detection data after the chip test, and the light source is adjusted through the data so as to realize that the light source can be adjusted to the requirements required by the chip test. The light source in the state can generate different differences along with the difference of the construction environments, and the state of the light source is completely judged from the test result, so that once the hardware environment is changed, the light source standard debugged on the basis is an error standard, and the difference between the standard environment and the light source standard is practically present and cannot be found in time although the test can be used.
