摘要 A digital image capture apparatus is provided which is arranged to capture at least two images of a document and combine the images to produce a final image in which the effects of specular reflection and/or ambient light are removed. The apparatus includes a light source and a first image is captured with the source illuminating the document. A second ambient image is captured with the light source switched off, and the images are combined either by subtracting the ambient image from the first image or by replacing areas of the first image by corresponding areas of the ambient image. <IMAGE>
