An information processing apparatus includes a display time acquiring unit that acquires a display time for each predetermined unit region of an image and a compression control unit that controls compression of the image for each unit region based on the display time. The material may comprise a metal, such as magnesium, which is converted to magnesium oxide when exposed to heat and a source of oxygen. Logical rules can be used to determine conditions under which to hold the state of an output clock based on the states of a first clock and a second clock and the state of a switch request signal. The apparatus includes a guiding element positioned adjacent to a cutting drum and has a wall closing a channel for a set of segments drawn out of a flute on the drum. When the physiological parameter exceeds a predetermined threshold level the sideline controller generates an alert that is received by the signaling device, which is typically worn by sideline personnel, such as coaching staff or trainers. The masking pattern is removed using a first post etch clean for stripping the masking pattern.
