color channel. Advanced rotating line cameras may have multiple linear CCD arrays on the focal plate and may capture multiple panoramic images during their rotation. Line-scan technology is capable of capturing data extremely fast, and at very high image resolutions. Usually under these conditions, resulting collected image data can quickly exceed 100 MB in a fraction of a second. Line-scan-camera–based integrated systems, therefore are usually designed to streamline the camera's output in order to meet the system's objective, using computer technology which is also affordable. Line-scan cameras intended for the parcel handling industry can integrate adaptive focusing mechanisms to scan six sides of any rectangular parcel in focus, regardless of angle, and size. The resulting 2-D captured images could contain, but are not limited to 1D and 2D barcodes, address information, and any pattern that can be processed via image processing methods. Since the images are 2-D, they are also

Panoscan

The Panoscan is a high resolution digital panoramic rotating line camera, manufactured by Panoscan Inc. The first Panoscan camera, called MK-1, was manufactured in 1999. The MK-2 and MK-3 models, with higher resolution and speed, followed. Panoscan uses a tri-linear CCD array and assembles an image by capturing a single line of pixels while rotating through a 400 degree arc. A full resolution, spherical image can be produced in under a minute.
Panoscan and Return to Scene Form Strategic Partnership, 2009 The camera produces digital images of 9,000 by 65,000 pixels that can be printed at 30 feet (10
