发明名称 IMAGE PICKUP DEVICE AND SIGNAL PROCESSING METHOD THEREOF
摘要 <p>An image pickup device is provided, capable of complete correction with data of once analog-to-digital conversion, and prevention of excess use of switches and analog devices and/or erroneous correction, including: an image sensor having a plurality of analog-to-digital converters determining conversion results from a digital signal of higher order bit through separate steps of two or more times; a first correction unit which 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 a nonlinear error of a digital signal output from respective analog-to-digital converters based on a correction factor corresponding to respective analog-to-digital converters, characterized in that the first correction unit corrects the nonlinear errors after converting the digital signals from the plurality of analog-to-digital converters into a serial output.</p>
