Patent ID: 8496173

Claim:
A camera-based code reader ( 10 ), comprising: an elongated base body ( 26 ) with a plurality of individual image sensors ( 32 ) mounted thereon, each of the plurality of individual image sensors ( 32 ) comprising a line-shaped individual reading area ( 18 a - d ) and being oriented and arranged relative to one another so that the individual reading areas ( 18 a - d ) overlap to form a line-shaped reading area ( 18 ), and wherein each of the plurality of individual image sensors ( 32 ) is configured to capture image data in the form of partial image lines of the respective line-shaped individual reading areas ( 18 a - d ), an evaluation unit ( 46 ) configured to compose a common image line from the image data of the partial image lines captured by the individual image sensors ( 32 ), and a decoding unit ( 48 ), wherein the plurality of individual image sensors ( 32 ) are further configured to capture successive partial images, and the evaluation unit ( 46 ) is further configured to compose the successive partial images into successive common line images and to compose an image from the successive common image lines, and wherein the decoding unit ( 48 ) is configured for locating and decoding code information in the image.
