Patent ID: 8058600

Claim:
A device for the acquisition of data obtained from reading at least one type of optical code having data coded therein by a combination of elements in accordance with pre-defined rules, comprising: means for generating an electric signal correlated to the brightness of an image including a CMOS optical sensor comprising a plurality of pixels arranged in a plurality of lines and columns; and acquisition means for acquiring an electric signal from at least one window of pixels of said CMOS optical sensor, said window comprising a sub-portion of said plurality of pixels, processing means for processing the electrical signal acquired from said window to extract optical coded data therefrom; reading means for attempting a reading of the extracted optical coded data, wherein said acquisition means is configured for acquiring an electric signal from at least one further window of pixels of said CMOS optical sensor when the reading attempt of the extracted optical coded data is not successful, said further window being different from said window in at least one of size and shape.
