Abstract
A scan method comprising a sensing photo module applicable in a scan apparatus for scanning a document is disclosed. The sensing photo module is equipped with photo sensors parallel to each other and detects the photo signal at every collection distance. The photo sensors extend horizontally and are positioned a line distance between the adjacent photo sensors. Under low operating resolution, the vertical resolution is increased by making the line ratio an integer, in order to solve the problem of color-quality loss due to a non-integer line ratio.
