Patent ID: 7787145

Claim:
A method for determining media type with a hand-held inkjet printer, wherein the hand-held inkjet printer has one or more optical sensors, the method comprising: collecting a first frame of individual pixel data with the one or more optical sensors when the hand-held printer is on a page to be printed, the collecting the first frame of individual pixel data including collecting a first pixel map using a predetermined first shutter speed and a first frame rate; by a controller, comparing the first frame of individual pixel data with one or more pixel data records to determine the media type of the page to be printed, wherein the comparing the first frame of individual pixel data further includes collecting additional pixel maps and the first frame rate is adjusted to compensate for hue shifts; and collecting still other pixel maps with the one or more optical sensors wherein the first shutter speed is ramped up and down until an average pixel value is determined by the controller to be at an optimal range.
