摘要：An image pickup device is provided, capable of complete correction with data ofonce analog-to-digital conversion, and prevention of excess use of switches and analogdevices and/or erroneous correction, including: an image sensor having a plurality of
analog-to-digital converters determining conversion results from a digital signal ofhigher order bit through separate steps of two or more times; a first correction unitwhich has a correction factor for correcting nonlinear errors of the plurality of analog-to-digital converters so as to adapt to the analog-to-digital converters and corrects anonlinear error of a digital signal output from respective analog-to-digital convertersbased on a correction factor corresponding to respective analog-to-digital converters,characterized in that the first correction unit corrects the nonlinear errors afterconverting the digital signals from the plurality of analog-to-digital converters into aserial output.
