Abstract: A reading module has a light source, an optical system imaging, as image light, reflected light of the light radiated from the light source to the document, and a sensor converting the image light imaged by the optical system into an electrical signal. The optical system has a mirror array in which reflection mirrors are coupled together in an array in the main scanning direction and an aperture stop portion having a first aperture adjusting the amount of image light reflected from a reflection mirror and a second aperture shielding stray light that enters the first aperture from an adjacent reflection mirror. The second aperture is arranged at such a position as to be able to shield stray light passing through a boundary between the reflection mirrors and the center of the first aperture when the mirror array contracts to the maximum extent in the main scanning direction.

Abstract: A method includes capturing plural frames of video data using a mobile device. The frames are analyzed to determine whether any depict an object exhibiting one or more defining characteristics, and if so, whether those frame(s) depicting the object also satisfy one or more predetermined quality control criteria. If one or more of the frames depict the object and also satisfy the one or more predetermined quality control criteria, the method further includes automatically capturing an image of the object. Exemplary defining characteristics are specified for various types of object, particularly objects comprising documents. Related systems and computer program products are also disclosed. The presently disclosed techniques and systems represent translational developments across the fields of image processing and business process management. Improved analytical techniques enable processing of image captured using cameras rather than traditional scanner technology, and facilitate distribution, tracking and analysis of documents and information throughout business processes.

Abstract: A light source driving circuit that drives a light source includes a driving electric current generator that generates a driving electric current including a predetermined electric current, a first auxiliary current, and a second auxiliary current; and a controller that sets values of the first and second auxiliary currents by using first and second lighting pattern signals, wherein each of the first and second lighting pattern signals is for controlling supply of the predetermined electric current to the light source. After setting a first value of the first auxiliary current, a second value of the second auxiliary current is set by using the second lighting pattern signal that defines a time period for stopping supply of the predetermined electric current to be shorter than a time period for stopping the supply of the predetermined electric current that is defined by the first lighting pattern signal.

Abstract: An optical scanner includes a light source, optical deflector, mirror, first photosensitive drum, and second photosensitive drum. The light source emits a first light beam and a second light beam. The optical deflector deflects the first light beam and the second light beam. The mirror has a reflecting part that reflects the deflected first light beam and a passing part that passes the deflected second light beam. The passing part is displaced from the reflecting part. The first photosensitive drum performs a development with a first toner having a first color. The reflected first light beam scans the first photosensitive drum in a main scanning direction. The second photosensitive drum performs a development with a second toner having a second color different from the first color. The passed second light beam scans the second photosensitive drum in the main scanning direction. The first photosensitive drum and second photosensitive drum are arranged in a sub scanning direction orthogonal to the main scanning direction.
