    摘要: An auto focus camera includes a usual zoom lens and provides a pseudo focal length mode, in which the size of focus condition detecting area, to the photographing scene to be printed, is variable. A pseudo focal length is stored and a focus condition is detected in accordance with a ray of light passed through the zoom lens. When the camera is in such a mode as to continuously detect focus condition for keeping an object in focus, or to be operated when the contrast of the object whose focus condition is detected is low, the focal length of the zoom lens and the pseudo focal length are controlled respectively in accordance with the mode.

    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.

    摘要: An optical system has the first, second, and third lens units from an object side. The first and third lens units have positive refractive powers. The second lens unit has a negative refractive power. The second lens unit moves toward an image side during focusing from an object at an infinite distance to an object at a finite distance. The second lens unit has a sub lens unit. The sub lens unit moves in a direction perpendicular to an optical axis to correct an image shake.
