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.
Claims15
An apparatus comprising:
- a scan surface comprising:
- a first zone;
- and
- a second zone;
- an image sensor to scan the scan surface;
- a lid coupled to the scan surface, the lid having an open position and a closed position relative to the scan surface, the lid to cover the first zone and the second zone when the lid is in the closed position;
- and
- a controller to cause the image sensor to scan the first zone and the second zone, the controller to determine whether the lid is in the closed position based on a comparison of the scan of the first zone and the scan of the second zone.
A non-transitory computer-readable medium to store machine-readable instructions that, when executed by a processor, cause the processor to:
- scan a first zone of a scan surface;
- scan a second zone of the scan surface;
- compare the scan of the first zone with the scan of the second zone;
- and
- determine whether a lid is open based on the comparison.
A method comprising:
- scanning a line of a scan surface;
- comparing a first zone of the line with a second zone of the line;
- and
- determining a lid is open based on the comparison, the lid being to cover the scan surface.
