Abstract: A digital camera and a printer are directly connected to each other, and a printing progress situation is displayed on a display unit of the digital camera while an image taken by the digital camera is being printed. Further, when a printing mode is changed to a photographing mode while the printing is being performed, the image being taken is displayed on the entire display unit, and the printing progress situation is superposed and displayed on a predetermined area of the display unit on which the image being taken is displayed.

Abstract: A film-forming apparatus is provided with a particle prevention means, whose structure prevents a drop in film-yield due to particle formation. The particle prevention means does not need to be cleaned as frequently as known particle prevention means, thus increasing film production efficiency. This particle prevention means has a tongued-and-grooved surface. When the particle prevention means having a tongued-and-grooved surface is set in the film-forming apparatus, the film-forming material is deposited in a discontinuous manner on the particle prevention means, which can extend the time of film exfoliation, and in turn, extend the cycle for cleaning the particle prevention means, and prevent a drop in film-yield due to the film exfoliation.

Abstract: An automatic focusing device includes an image pickup device for outputting an image signal by performing photoelectric conversion of an image of an object, a band-pass filter for extracting a sharpness signal corresponding to the sharpness from among the image signal, a diaphragm for controlling the amount of light incident upon the image pickup device, and a control circuit for controlling prohibition of the drive of a focusing lens based on a change in the sharpness signal output from the band-pass filter and a change in the state of the diaphragm. It is thereby possible to exactly detect an operation, such as panning or the like, and to prevent the stop of the focusing lens at a defocused position caused by an erroneous operation by prohibiting the drive of the focusing lens when panning has been detected.

Abstract: An apparatus for producing monomolecular films or monomolecular built-up films includes: a trough for accommodating a liquid over the surface of which a monomolecular film is to be spread; a barrier band for defining a region in the trough over which the monomolecular film is allowed to be spread; and a plurality of supports for holding the barrier band within the trough, the supports being arranged at positions where they do not interfere with the surface of the liquid, wherein the loss of the monomolecular film material can be substantially reduced. Further, no local collapse of the molecular film occurs in the vicinity of the supports, thereby making it possible to always provide a uniform LB film.

Abstract: A focusing screen includes a regular array of a plurality of unit regions on an optically transparent substrate, and an irregular array of a plurality of minute patterns of at least two different sizes in convex or concave form on a surface of the substrate.

Abstract: An illuminating optical device including: a light source for emitting a light beam; and an illuminating optical system for receiving the light beam from the light source to irradiate an object with the light beam, the illuminating optical system having an optical axis and an illuminance-distribution changing lens system which is movable in the direction of the optical axis to change an illuminace-distribution forming characteristic of the illuminating optical system.

Abstract: A video signal processing device for separating horizontal and vertical synchronizing signal components from an applied video signal, for forming a field discrimination signal upon discriminating the field represented by each field video signal on the basis of the separated horizontal and vertical synchronizing signal components, and for detecting abnormality or deviation from a predetermined variation in the field discrimination signal due to a defect of the synchronizing signal components or a different type or format of a video signal.

Abstract: This specification discloses a scanning illuminating device in a copying apparatus of the slit exposure type in which a movable slit area of an original is projected upon a movable photosensitive medium by a projection lens. The device is characterized in that light sources are fixed to the opposite end portions of the original surface with respect to the scanning direction, the magnification of the light source image becomes gradually greater at one end of the scanning direction and gradually smaller at the other end of the scanning direction, and imaging elements are moved in the scanning direction so that the illumination distribution on the original surface is formed so as to compensate for the loss of quantity of light of the projection lens due to the so-called cos biquadratic rule or the like to thereby enable copying of uniform density in the scanning direction.
