A sheet surface inspection system, equipped with the monochrome line scan cameras, uses inspection object’s contrast and shape data for defect classification. Therefore it makes difficult to classify the defects by color. Another reason for the difficulty of defect classification by color is that the conventional color line scan camera (drive frequency : 40MHz) is not capable of having enough MD resolution for clear image.
Now, FUTEC has developed a new surface color inspection system, “MaxEye. Color”, using high-speed color line scan camera technology with a drive frequency of 80MHz. Three main features of this system are : (1) a clear color image of defect, (2) an intuitive color defect classification setting, (3) a real-time color defect classification .
This system enables operators to see sharp, clear color view of defects to determine the cause of defects in early stage of production. Furthermore, it carries out the automatic defect classification for color defects only by using real time processing function. This function contributes to the operation efficiency by supporting operators’ checking process.
