Rotating line camera

A rotating line camera is a <a href="/facts/Digital_camera/LSGTserm">digital camera</a> that uses a linear <a href="/facts/Charge-coupled_device/l6xffIcz">CCD</a> array to assemble a digital image as the camera rotates. The CCD array may consist of three sensor lines, one for each <a href="/facts/RGB/3Be0zwCj">RGB</a> 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 <a href="/facts/Human-readable/GDE1fpHT">human-readable</a> and can be viewable on a computer screen. Advanced integrated systems include <a href="/facts/Video_coding/Dmzykxmn">video coding</a>, <a href="/facts/Optical_character_recognition/kdTyxa1l">optical character recognition</a> (OCR) and finish-line cameras for high speed sports.
