摘要： An autozoom apparatus for a camera having an operating member for designating a first point and a second point in a scene to be photographed; a circuit using an angular velocity sensor for detecting a displacement angle of the camera when the camera is rotated from the first to second points; an autofocus circuit for measuring the object distance; a zoom encoder; a zoom motor; and a circuit for controlling the zoom motor. The autozoom apparatus calculates a focal length corresponding to the picture frame defined by the first and second points and makes automatic zooming to the calculated focal length.

摘要： The present invention relates to an LCD unit that has a reflective liquid-crystal panel including two glass plates with a liquid crystal locked in between, two polarization plates affixed to outer sides of the two glass plates, and a reflection plate arranged under the lower polarization plate. The LCD unit further comprises a light accumulating part that is arranged under the liquid-crystal panel in order to illuminate the liquid-crystal panel and that accumulates light and glows, and a light guide for efficiently introducing light entering externally to the light accumulating part.
