The mobile device 102 includes a camera (which is not shown in FIG. 1). The camera of the mobile device 102 has a field of view. The field of view of a camera is the part of the world that is visible to the camera at a particular position and orientation in space. The field of view of the camera may be expressed in terms of an angular size.
The mobile device 102 also includes one or more illumination sources (which are also not shown in FIG. 1). Each illumination source emits a field of illumination. The field of illumination emitted by an illumination source refers to the part of the world that is illuminated by (or, in other words, receives light from) the illumination source. The field of illumination of the illumination source may also be expressed in terms of an angular size.
The presentation stand 100 includes a shield portion 118 attached to the cradle portion 110. The shield portion 118 may include one or more optic systems (not shown in FIG. 1) that are configured to enhance the barcode-reading capabilities of the mobile device 102. More specifically, the optic system(s) within the shield portion 118 may be configured to modify the field of view of the camera of the mobile device 102 and the field of illumination of the illumination source(s) of the mobile device 102, thereby altering the characteristics of images that are captured by the mobile device 102. The optic system(s) within the shield portion 118 may alter the characteristics of the captured images in such a way that the captured images are more suitable for reading barcodes than they otherwise would be.
