Application No. 08/759,346
to be used by label reader 108 (col. 4, lines 36-39). Holeva
further describes the high-resolution camera as:
Camera 110 may be a conventional high-resolution,
variable-focus camera and is preferably a 4096-pixel CCD
line-scan array to enable perception of details on package
labels.
(Col. 4, lines 40-43).
Holeva further describes the low-resolution cameras as follows:
The specific characteristics of the optical components
of optical system 114 of dual-camera optics 104 depend on
the particular application and may be selected empirically.
(Col. 5, lines 5-8).
The specific component characteristics described below apply
to a preferred embodiment of the present invention designed
to provide a depth-of-view of approximately 24 inches and a
field-of-view of approximately 18 inches. (Col. 5, lines
11-15).
Array 212 and 218 may be conventional CCD line-scan arrays
and are preferably 256-element CCD line scan arrays. In a
preferred embodiment, camera 206 has a f-number of 12.5 and
camera 208 has an f-number of 1.25. In alternative
preferred embodiments, f-numbers for cameras 206 and 208 are
selected to provide an f-number ratio of greater than 10.
(Fig. 2 and Col. 5, lines 25-31).
Therefore, Holeva provides no information regarding the relative
field-of-view of the low-resolution and high-resolution cameras
104 and 110 and is merely concerned with the resolution of the
cameras. Although camera 110 has a higher resolution, it still
captures an image of the top of the package based on the distance
rather than the position of the label on the top surface of the
