ABSTRACT:
A scanner system for detecting images on a surface and generating an electronic representation thereof for transmission to an image processing system, including at least first, second and third rows of n sensors generating charges representative of detected light of preselected wavelengths during an integration period of a selected duration. Each row of sensors is comprised of substantially similar construction, and suitable for detection of a preselected wavelength, Sensors may be chosen from a sensor type which facilitates transfer of charges through the sensor. The sensor rows are provided with discharge paths interconnecting each sensor in a row in charge passing relationship with a sensor in a successive row, and a storage device, whereby sensors in a first row are discharged to a storage device through sensors in the second and third rows; sensors in a second row are discharged to a storage device through corresponding sensors in a third row; and sensors in a third row are discharged into a storage device prior to transmission of charges as output information. The charges are passed to the storage device between integration periods. A new integration period may be started as soon as data from the first row sensors reaches a storage device.
