摘要： A camera having an image shift detecting function is provided with an optical system which forms a subject image, an image sensing device which converts light of the subject image into an electric signal, an image shift detecting sensor which detects a relative shift between the camera and the subject image based on an output of the image sensing device and a microcomputer which compensates for the relative shift between the camera and the subject image based on an image shift amount detected by the image shift detecting sensor. The microcomputer specifies an area of the image sensing device based on a direction of luminance variation of the subject image and the image shift detection is made by using only an output corresponding to the specified area.

摘要： An apparatus has a member to be driven, an actuator for driving the member, a position detector and a controller. The actuator drives the member to move by an amount proportional to a given number of pulses. The position detector detects a position of the member in predetermined detection steps. The controller determines in steps smaller than the predetermined detection steps a target position up to which the member is to be moved. Then, it controls the actuator up to a detection-step position before the target position by closed-loop control in accordance with a detection result from the detector. Further, it controls the actuator from the detection step position to the target position by open-loop control.

摘要： A projection optical system (6) comprises a relay optical system (61), a PBS prism (71), and two projection lenses (81). The image light beam from a DMD (5) enters the PBS prism (71) via the relay optical system (61), is polarization-split there, and is directed to a screen by means of the two projection lenses (81). Displaying an image by means of the DMD (5) is controlled while the polarized states of the light beams produced by the polarization split by means of the PBS prism (71) are controlled. Thereby, a three-dimensionally viewable image and a high-resolution image created by pixel-offset can be projected. Since the relay optical system (61) is provided, the lens backs of the projection lenses (81) can be shortened, and the projection lenses (81) and further the projection optical system (6) can be made compact.
