Abstract
An improved scanner with automatic edge detection capable of quickly, accurately, and readily detecting the edges of a document or an object to be scanned. Said scanner with automatic edge detection comprises a main body, a scanning module, and an edge detector. The main body comprises a flat glass platform for supporting an object. The scanning module is installed inside the main body for scanning the image of an object placed on the flat glass platform of the scanner. The edge detector is located inside the main body to detect the edges of the object, thereby determining the size of the object before scanning. The scanner according to the present invention is capable of obtaining the correct size of the object being scanned without restricting the size of the object to match any of the fixed paper sizes in order for such scanner function as auto zooming to proceed successfully. In addition, through a microprocessor and a properly embedded computer program of a disclosed art, the scanner according to the present invention is capable of auto zooming on the scanned object without the assistance of a computer and a monitor.
