A Device which enables a person to see for himself changes in Intra Ocular Pressure when he looks at his eye in the Mirror, in the routine course of everyday, as every one likes to see his Own face and eyes in the Mirror everyday. The flexible connection unit includes an elongated member, such as a vertebral rod, having a first end portion and a second end portion opposite each other with a transition portion extending therebetween. Thereafter, the CPU performs an image correction process on the plurality of picked-up images picked up sequentially to correct the distortion of the image of the object included in each picked-up image, using the calculated correction data. Each of the EBG waveguide phase shifters is a waveguide with vertical and horizontal sidewalls. A focusing position is determined from a graph of focusing integrated values obtained in the formal search. The present invention reduces the jitter on the TMDS clock, and hence the audio DAC clock, resulting in lower audio distortion.
