Abstract
A method of increasing the dynamic range of a captured image using a pixel array having a plurality of rows includes reading first pixel information corresponding to a long integration period from each pixel of a first row, reading second pixel information corresponding to a short integration period from each pixel of the first row, and merging the first pixel information and the second pixel information to thereby produce wide dynamic range pixel information for each pixel of the first row. Reading first pixel information takes place during a first interval, reading second pixel information takes place during a second interval, and at least a portion of the second interval takes place during a long integration period corresponding to a second row of the pixel array.
