Abstract

An automatic cresset detection method and a light sensing device for the method are used for adjusting the detection sensitivity value of the light sensing device to a light-emitting diode. The method comprises the steps that the light sensing device selects random one from detection sensitivity values, defines the selected detection sensitivity value as an initial detection sensitivity value, divides the detection sensitivity values into a raising detection group and a reducing detection group according to the initial detection sensitivity value, detects the color value sent by a light-emitting diode according to the initial detection sensitivity value, selects a new initial detection sensitivity value from the raising detection group or the reducing detection group according to detection result, and repeatedly detects the color value of the light-emitting diode according to the new initial detection sensitivity value until the initial detection sensitivity value is not changed.

Description

technical field

[0001] The invention relates to a detection method and a sensing device, in particular to an automatic lamp signal detection method and a light sensing device thereof. Background technique

[0002] With the rapid development of integrated circuits, the processing capability of computer devices is also improved. In order to indicate the running state of the computer device during operation, different lights are provided in the computer device, so that the user can check whether the computer device is abnormal. Generally speaking, in order to achieve energy saving and low cost considerations in computer devices, light-emitting diodes (light-emitting diodes, LEDs) are often used as their lights.

[0003] Therefore, in order to determine whether the display of the light signal of the computer device is correct, it is also necessary to measure the light signal in the production line. In the conventional measurement method, the operator performed visual inspectio...
