A computer peripheral that may operate as a scanner. The scanner captures image frames as it is moved across an object. The image frames are formed into a composite image based on computations in two processes. In a first process, fast track processing determines a coarse position of each of the image frames based on a relative position between each successive image frame and a respective preceding image determine by matching overlapping portions of the image frames. In a second process, fine position adjustments are computed to reduce inconsistencies from determining positions of image frames based on relative positions to multiple prior image frames. The peripheral may also act as a mouse and may be configured with one or more navigation sensors that can be used to reduce processing time required to match a successive image frame to a preceding image frame.

The flexible flat cable includes a plurality of conductive wires, an insulating covering member, and a reinforcing plate. The thin conductive wires are arranged in parallel with one another in a direction perpendicular to the thickness direction thereof. The insulating covering member covers faces of the conductive wires, on at least one side of the conductive wires in the thickness direction. The reinforcing plate covers and reinforces the end parts of faces of the conductive wires in the thickness direction. The faces on the other side of the conductive wires in the thickness direction include exposed faces adjacent to the end parts. The exposed faces are not covered with the reinforcing plate and covering member.

Provided is a positioning adjustment apparatus for a mobile device in scanning and photography, including a main body and a lifting unit. An object to be scanned is placed on the main body, and the mobile device placed on a carrier platform of the lifting unit can move up and down along with the lifting unit to adjust a distance between the mobile device and the object to be scanned. After scanning, a document is sent directly to a shredder. The invention also provides a wireless signal transmission to operate the mobile device for scanning or photography to meet various demands of the users.
