Patent ID: 8229175

Claim:
A system for determining a quality of an anisotropic conductive film, the anisotropic conductive film comprising conductive particles dispersed therein, the system comprising: an image capturing device configured to capture an image of the anisotropic conductive film; and an image processing device coupled to the image capturing device, the image processing device configured to process the image to generate a first binary image, the first binary image comprising a plurality of first objects representing the conductive particles, the first objects occupying a first area in the first binary image, the image processing device also configured to process the first binary image to generate a second binary image having a different size with respect to the first binary image by a predetermined value, the second binary image comprising a plurality of second objects corresponding to the plurality of first objects, the second objects occupying a second area in the second binary image, the image processing device further configured to calculate the number of the conductive particles according to the first area, the second area, and the predetermined value, thereby the quality of the anisotropic conductive film can be determined; wherein the image processing device is further configured to process the first binary image to generate the second binary image as a smaller version of the first binary image by a ratio determined by the predetermined value.
