Abstract: In an image sensor including a light emitting element for emitting a light beam to be incident on a document, a light receiving element for receiving the light beam reflected by the document, and a lens array for directing the reflected light beam from the document to the light receiving element, there is located a mirror between the lens array and the light receiving element for changing the direction of the light beam passing through the lens array. The light emitting element and the light receiving element are located on the same substrate. With this arrangement, a compact and inexpensive image sensor can be achieved. This compact image sensor causes an increased amount of light to be incident on the document.

Abstract: The invention includes a method and system for improving the output quality of an image forming device. The method includes comparing an amount of speckle present in the images with a predefined amount of speckle. Thereafter, it is evaluated whether an adjustment of an angle of inclination of an image capture assembly in the image forming device is required for improving the output quality of the images. Accordingly, the height of one or more spacers of a spacer assembly may be altered for inclining the image capture assembly with respect to a transparent surface on which an object to be scanned by the image forming device is placed. The height of the spacer assembly may be adjustable by a user or pre-set to an optimum level for reducing the speckle to a value less than or equal to the predefined amount of speckle.
