Abstract: A CAD system having a plurality of clients connected by a network enables simulations to be run that reflect design information from other client CADs. A server 100 causes a computing unit 101 to reflect in a three-dimensional model generated based on design according to any given client 110-140 design data according to any other client 110-140. Then, using that three-dimensional model, the server carries out an operating simulation and transmits the simulation results to the requesting client. The client that receives the simulation results from the server 100 then displays those simulation results on a design screen.

Abstract: The invention discloses an image reading apparatus in which a linear image sensor is provided in the vicinity of an imaging optical system and the main scanning operation is achieved by electronic scanning of the linear image sensor in the longitudinal direction thereof while the sub scanning operation is achieved by the relative movement of the linear image sensor and the image formed by the imaging optical system with plural scanning speed and the image information is outputted by communication between the image process means for processing the image obtained by each main scanning operation and the external equipment, the apparatus is featured by fetching plural shading data while a scanning motor in the sub scanning direction is driven with such plural scanning speeds.

Abstract: In an image reading apparatus for reading an image recorded on a film, an amount of light being incident on a line sensor comprised in the apparatus and transmitted through the film is adjusted according to the image density of the film such that a relative speed between the film and the line sensor and the luminance of a lamp for irradiating light on the film are controlled.

Abstract: In an image read system which reads an image recorded on a film capable of holding incidental information of the image in an area different from the area where the image is recorded, the incidental information of the image recorded on the film is read, and the read image and the incidental information is processed and outputted as data of a single image.

Abstract: An image pickup apparatus includes a zoom lens, an electronic-zoom part for varying a magnification by subjecting a video to the processing of electronically varying an angle of view, a detecting circuit for detecting a spatial frequency of the video signal, and a control circuit for controlling a magnification of the electronic-zoom part on the basis of information indicative of the spatial frequency detected by the detecting circuit.

Abstract: A film scanner is capable of reading an image formed on a film in accordance with a photographing mode recorded in each frame of the film. In this film scanner, an image formed in each frame of a film held by a film holder is projected onto a linear image sensor by a focusing optical system to read the image with the linear image sensor. A magnetic information detection unit detects magnetic information recorded in each frame of the film, and a system controller identifies a photographing mode of each frame of the film. In accordance with the identified photographing mode, an image read area of each frame is set and a subscanning motor is driven in accordance with this image read area. The subscanning motor is driven in the area outside of the image read area at a faster speed than in the image read area. Therefore, a read time can be shortened as compared to the case wherein all frames are read in the broadest image read area. Trimming works can be omitted.

Abstract: An image pickup apparatus is disclosed which is provided with a distortional-aberration memorizing element for memorizing distortional-aberration information about an objective lens, a state-of-objective-lens detecting circuit for detecting a state of the objective lens, an image correcting circuit for reading out distortional-aberration information about distortional aberration occurring during photography from the distortional-aberration memorizing element on the basis of information supplied from the state-of-objective-lens detecting circuit, and electrically correcting a distortion of an image due to the objective lens with a predetermined image height in a photographed image selected as a datum.

Abstract: A lens driving device includes a stator, a rotor magnetized to have a plurality of poles, an arm fixed to the rotor in such a manner as to be rotatable together with the rotor, a moving member for rectilinearly moving a lens in response to a rotation of the arm and a coil for causing the stator to generate a magnetic flux to rotate the rotor.

Abstract: An optical apparatus or a control device to be used for a light flux deflecting apparatus is arranged to include at least two light flux deflecting portions and a control portion which control the driving actions of the at least two light flux deflecting portions in such a manner that, with the light flux deflecting portions applied as image shake preventing mechanisms to an optical apparatus using a plurality of light fluxes, such as a binocular, the arrangement effectively prevents such inconveniences as the necessity of using a plurality of control portions in controlling each of the light flux deflecting portions and giving a disagreeable feeling to the user due to a discrepancy arising in the amount of deflection between two light fluxes.
