摘要： A lens-fitted film package comprising a light-tight case having at least a taking lens attached to a front wall thereof and a roll of film contained therein and a lens holder attached to the light-tight case. The lens holder is formed with a conversion lens holding opening for holding a conversion lens therein and a view-defining opening for defining the field of view of a viewfinder formed in the light-tight case. The lens holder is slidably moved with respect to the light-tight case so as to position the lens holder at a distance from the front wall of the light-tight case wherein the conversion lens changes the effective focal length of the taking lens and the view-defining opening defines the field of view of the viewfinder suitably for the effective focal length of the taking lens thus changed.

摘要： A camera has a lens system changeable as to focal length, which is driven by a driving device so as to change the focal length thereof. The driving mechanism includes a first shifting mechanism for shifting one lens of the lens system stepwise to predetermined positions in a direction parallel to the optical axis of the lens system and a second shifting mechanism for shifting another lens of the lens system stepwise with respect to the one lens in that same direction, thereby changing the focal length of the lens system.

摘要： A copying machine for making a hard copy of an original comprises an image sensor for reading an image of the original to provide image signals, a memory for memorizing the image signals after or before processing the image signals for necessary corrections, and a printer for printing an image on a copying sheet according to the image signal after image processing. Preferably, a thermal printing head and a heat sensitive sheet are used. The copying machine is compact and either is incorporated in a portable overhead projector or is used as a writing board copy machine. In the former case, the image sensor is disposed in a supporting arm for supporting an image projection lens assembly above a base section of the overhead projector on which a transparent original is placed. The image sensor reads a reflecting original to provide image signals and the thermal printing head prints a mirror image of the reflecting original on a transparent heat sensitive sheet according to the image signals provided by the image sensor, thereby providing a transparent secondary original instantly for projection. In the latter case, the machine includes a pattern projector for projecting a light pattern which will be deformed on the remote original according to position of the copying machine, whereupon a correcting circuit provides a correction signal. The heat sensitive sheet is formed with indicia near front and rear diagonally opposite edges, symmetrically with respect to the center of the sheet, to indicate at least the surface of the sheet to which a heat sensitive material layer is applied.

摘要： A digital camera includes a distortion correction section, which is composed of a focal length determining section, a distortion evaluation section and a correction amount calculating section. The focal length determining section evaluates a focal length at the time of image capture. Based on the focal length, the distortion evaluation section evaluates the magnitude of wide-angle distortion and optical distortion in a captured image. Based on this evaluation, the distortion correction section selects an appropriate coefficient from an optical distortion correction coefficient table or a wide-angle distortion correction coefficient table. Using the selected coefficient, the correction amount calculating section applies a coordinate transform processing to cause positive or negative distortion to the captured image, and corrects the wide-angle distortion or the optical distortion.

摘要： An image-taking apparatus including an auxiliary light projecting section that is small in size in spite of using multiple projection elements and is capable of performing extensive illumination to a range including parallax while maintaining a certain degree of brightness until reaching a given distance, and a projection module suitable for being loaded on the image-taking apparatus are provided. This apparatus projects light from three light points onto an object in a projection pattern shown in part (b) of FIG. 11 by use of a lens split into three regions. The light from the three light points is formed respectively into three beams by use of each of projecting sections subjected to region splitting, and single light beams out of sets of three beams are projected so as to overlap one another.
