Detection apparatus, method and system

A detection method, adapted for detecting whether color filters are qualified or not, wherein the color filters comprise a plurality of long rectangular pixel units arranged in a regular manner;

• and the detection method comprise:
• obtaining an orientation of the pixel units on the color filters to be detected;
• judging whether a current light direction of a light source coincides with the orientation of the pixel units on a first direction or a second direction, wherein the second direction is perpendicular to the first direction;
• adjusting the light direction when the light direction does not coincide with the orientation of the pixel units, to make the light direction coincide with the orientation of the pixel units;
• obtaining image data of the color filters;
• performing a data processing on the image data and judging whether there is an unqualified pixel in the pixel units according to a result of the data processing.

A detection system, adapted for detecting whether color filters are qualified or not, wherein the color filters comprise a plurality of long rectangular pixel units arranged in a regular manner;

• and the detection system comprise:
• an inspecting unit, configured to obtain an orientation of the pixel units on the color filters to be detected;
• a judging unit, configured to judge whether a current light direction of a light source coincides with the orientation of the pixel units on a first direction or a second direction, wherein the second direction is perpendicular to the first direction;
• an adjusting unit, configured to adjust the light direction when the light direction does not coincide with the orientation of the pixel units, to make the light direction coincide with the orientation of the pixel units;
• an image obtaining unit, configured to obtain image data of the color filters;
• a processing unit, configured to perform a data processing on the image data and judge whether there is an unqualified pixel in the pixel units according to a result of the data processing.
