Abstract:
An image sensing module for scanning a scanning object, the image sensing module comprising:a housing having a crossing section having a shape being rectangular, the housing having an elongated opening along one of corners of the housing; an image sensor; an optical system mounted before the image sensor; an illumination source providing illumination to the scanning object through the elongated opening; wherein the image sensor, the optical system and the illumination source are collectively packed as an integrated part positioned at an angle in reference to the housing such that dimensions of the housing are minimized without affecting original dimensions of the image sensor, the optical system and the illumination source; and wherein, when the image sensing module is integrated at an end of a portable computing device that is hold tilted with respect to the scanning object, the illumination source projects light onto the scanning object through the elongated opening, the optical system collects conveniently reflected light from the scanning object through the elongated opening and subsequently focuses the reflected light onto the image sensor to generate an image signal of the scanning object.
