Abstract: A first zone and a second zone of a scan surface may be scanned by an image sensor. A lid may be coupled to the scan surface and have an open position and a closed position, the lid being to cover the first zone and the second zone when in the closed position. The position of a lid may be determined based on a comparison of a scan of the first zone and a scan of the second zone.

Abstract: Example implementations relate to streak compensation. Some examples may calibrate an initial gain for data from an optical element based on a scan of a first calibration target, obtain an image of a second calibration target from the optical element using the calibrated initial gain, and detect at least one streak in the image of the second calibration target. Some examples may also record data representing the at least one detected streak and may calibrate a final gain for the optical element based on the initial gain and the data representing the at least one detected streak.

Abstract: A scanner includes a scan surface, a scan, a controller, and a positioning system. The scan surface is stationary and has a first width while the scan module has a second width substantially less than the first width. The controller is configured to automatically cause two scans of a media on the scan surface, without repositioning the media, and to automatically produce a composite image of the entire media from the two scans. The positioning system is in communication with the controller and includes an identification mechanism configured to identify an edge of a scanning area associated with the scan surface and to stop a position of the scan module at the identified edge.

Abstract: A scanner comprises a first gear assembly on a frame, a stationary scan surface having a first width, and a scan module having a length substantially less than the first width. The scan module includes a second gear assembly configured to move the scan module, in a first orientation generally perpendicular to the first width, in a first scanning path relative to a first width portion of the scan surface and in a second, non-duplicative scanning path relative to a second width portion of the scan surface. The second gear assembly is releasably engageable to the first gear assembly to selectively shift the scan module, in a second orientation generally perpendicular to the first orientation, between the respective first and second scanning paths.

Abstract: In a method for processing an image, a scene to be captured is divided into multiple zones and statistical values for a plurality of the multiple zones are obtained. In addition, a short-exposure time and a long-exposure time from the statistical values of the plurality of zones are determined. A long-exposure frame is captured at the long-exposure time and a short-exposure frame is captured at the short-exposure time. The long-exposure frame and the short-exposure frame are combined into a combined image while correcting for motion estimated to have occurred between the long-exposure frame and the short-exposure frame, and the combined image is stored.

Abstract: An image capturing system capable of providing an optimal exposure setting and method of operating the same are disclosed. The image capturing system includes a CMOS image sensor having photosensitive cells; a lens module having a mechanical shutter; a memory having a program for exposure analysis and a program for detecting motion stored therein; and a controller having a processor. The processor is configured to execute the program for exposure analysis and the program for detecting motion. The exposure analysis includes determining the exposure time for capturing an image of a scene based on the brightness of the scene and comparing the exposure time with the closing time of the mechanical shutter. The controller is operable to set the image capturing system to either a “Global-Reset mode” or an “Electronic-Rolling-Shutter” (ERS) mode based on the output of the exposure analysis and motion detection.
