Abstract

An image pickup apparatus and method are provided. The method includes performing a first and second reset operations with respect to a charge accumulated in first and second pixel lines, respectively, of an image pickup device, each of the first and second pixel lines having a plurality of pixels; traveling a light shielding member on the first and second pixel lines, respectively when first and second respective exposure times elapse from the first and second reset operations, respectively; outputting the charge accumulated in the first and second pixel lines, respectively, as first and second pixel data, respectively, after the light shielding member travels on the first and second pixel lines, respectively; and computing a first calibration value for the first pixel line and a second calibration value for the second pixel line based on the first and second pixel data and the first and second exposure times.
