发明名称 FOCUS DETECTION DEVICE AND IMAGING APPARATUS HAVING THE SAME
摘要 <P>PROBLEM TO BE SOLVED: To provide a focus detection device having imaging pixels and focus-detecting pixels using a phase-difference detection method that implements high-precision focus detection. <P>SOLUTION: In the focus detection device, a plurality of pixels each having a photoelectric conversion part for converting an incident light flux into signal charges, and a microlens having a focus position near the photoelectric conversion part are arranged. The plurality of pixels include a plurality of imaging pixels for generating a shot image, and a plurality of focus-detecting pixels for generating an image signal for focus detection by the phase-difference detection method. An opening for giving a pupil division function to the focus-detecting pixel is formed using electrodes arranged to read out the signal charges from the photoelectric conversion part. <P>COPYRIGHT: (C)2010,JPO&INPIT
