Abstract:
A digital camera has first and second light sources for sequentially illuminating a document from two different directions in response to the camera being activated. The camera has first and second sensor portions. Only the first and second sensor portions respectively respond to images reflected from the document in response to the first and second sources illuminating the document. Images detected by the first and second sensor portions are combined to remove specular reflection from the document image. In a second embodiment, the camera has three sensor portions.
