An image processing apparatus includes a correlation value map generation unit configured to generate a correlation value map by setting a target block, having a predetermined size and including a plurality of pixels, on a target image, and obtaining correlation values with a plurality of reference blocks corresponding to a target block set on a reference image different from the target image. A voice signal is obtained and two or more voice recognition analyses are performed on the voice signal. A relay system includes a second body communication unit that receives data from the at least one wearable monitor and communicates with the first body communication unit utilizing the near field capacitive body coupled protocol. A control logic processor selectively sets at least either said first set of setup voltage conditions or said second set of setup voltage conditions for the photosensitive medium. The metal layer under the thick IMD layer may act as the bottom electrode connection.
