摘要:
The principles of geometrical projection can be demonstrated with a drawing aid which preferably can be assembled from a kit of parts and which comprises an elongate base (10) carrying a number of object and image elements which can be set at different positions along the base and in different attitudes. These elements may comprise for example a sighting rod (19), a transparent sheet-form element (17) which defines a picture plane and on which the user draws images, an object (15), and a reflector (18). Perspective, orthographic and oblique projections can be demonstrated with just the one instrument using appropriate slots and holes to mount the elements.

The invention concerns a device (1) enabling a user (2) to draw an observed scene (3), on a support (4), such as a drawing board, comprising a first mirror (5) and at least a second mirror (6), said mirrors (5, 6) being arranged so as to reflect the image of the support (4) on an eyepiece (7) in front of which the user (2) can place a first eye (8). The invention is characterised in that it comprises a secondary support (10) adapted to be urged between the scene (3) and a second eye (8'), so as to produce a closer scene (3').

Cette invention concerne un système de communication télévisuelle permettant de réaliser une création graphique avec communication à distance. Ce système comprend un projecteur (1,21) qui projette des images sur la face inférieure d'un écran (7, 24) a travers un miroir dichroïque (8,23). L'image de l'écran est renvoyée par ce miroir à des moyens de prise de vues (14, 25) qui sont reliés à un système de mémorisation, d'enregistrement et (ou) de reproduction (15, 17). L'écran comprend une feuille semi-transparente (10, 29) qui peut être munie d'une couche photo-sensible. L'image projetée du dessous sur l'écran est visible pour un opérateur qui peut la modifier depuis le dessus de l'écran. Ce système permet une animation des images projetées par leur modification et est utilisable pour les conférences, l'enseignement, les tests, etc...
摘要:
A proportioning device having two elongated members (12,14) which are uncouplably joined at a pivotable joint (20) which may be at various predetermined positions (18). Both ends of both of the elongated members terminate at pointers (26,28,30,32), and the pointers at at least one pair of corresponding ends are adjustable. By variation of the pivot point (20) and the position of the adjustable pointer (26,28,30,32), it is possible to obtain a wide range of ratios of lengths between the pivotable joint (20) and the pointers (26,28,30,32) at the two ends of the elongated members (12,14). The device can be used to transfer a series of proportioned dimensions from an original object to an image or reproduction.

Zum Aufbringen von Bearbeitungsmarkierungen auf Holzbalken eines Dachstuhls wird vorgeschlagen, mittels eines rechnergesteuerten Markierungsprojektors (5) Lichtmarkierungen (15) auf den Holzbalken (13) zu projizieren und dann die Lichtmarkierungen mittels eines Zeichenwerkzeugs, beispielsweise eines Bleistifts dauerhaft nachzuzeichnen. Der Holzbalken wird nachfolgend herkömmlich, beispielsweise handwerklich bearbeitet. Die Abbundarbeiten des Dachstuhls lassen sich so beträchtlich verkürzen.
摘要:
Disclosed herein is a method of controlling an electronic apparatus. The method of controlling an electronic apparatus includes: selecting a specific image; generating a first image having a contour line and an adjusted transparency for the selected image; and displaying the generated first image in a state in which the generated first image is overlapped with a photographed image corresponding to live-view-photographing of the electronic apparatus.
