摘要:
Method and apparatus for preparing photographic film units having image frame associated encoded data. The method has the steps of: providing a filmstrip having a plurality of image frames and encoded data relating to individual image frames; reading the encoded data; locating the image frames; identifying data units; correlating individual data units and individual image frames; and rerecording data units on the filmstrip in physical association with respective image frames.

Apparatus (10) for positioning film media (30, 50) in alignment with video imaging means includes frame means having a window (28), primary gate means (12) mounted on the frame means for holding film media in a first plane, secondary gate means (13) mounted on the frame means for holding film media in a second plane, and, sensor (14) for detecting the presence or absence of film media whereby the video imaging means is caused to move with respect to the primary and secondary gate means to focus on the film media. A carrier (61) comprising a base (80) and cover (81) is provided with a channel (83) for filmstrips (50). The base and cover snap together for the removal and insertion of filmstrips. A plurality of notches (78) are associated with each frame (76) for accurate positioning of the filmstrip.

An apparatus (1) for projecting images in sequence comprises a light source arranged in such a way as to direct a light beam in a direction of projection, a plurality of filters (4) with impressed shapes, able to project images corresponding to said shapes when traversed by the light beam, a conveyor element (5) defining a closed line, movable in continuous cycle, the filters (4) being associated to the conveyor element in such a way as to intercept the light beam to generate an animated effect in the projection; the conveyor (5) defines a line having at least one rectilinear segment arranged in such a way that the filters (4) intercept the light beam moving along a straight line perpendicular to the light beam. The projections can be of planar geometric shapes applicable to any lighting apparatus. In projection apparatuses currently in use, the animated effects obtained by moving filters have poor effectiveness, because the filters are constrained to move with circular trajectory.

摘要:
Un appareil (10) permettant de positionner des supports de film (30, 50) en alignement avec des moyens d'image vidéo comprend des moyens de cadre ayant une fenêtre (28), des moyens de porte primaires (12) montés sur les moyens de cadre pour maintenir les supports de film dans un premier plan, des seconds moyens de porte (13) montés sur les moyens de cadre pour tenir les supports de film dans un second plan et un détecteur (14) pour détecter la présence ou l'absence des supports de film pour faire en sorte que les moyens d'image vidéo se déplacent par rapport au premier et au second moyens de porte pour se focaliser sur les supports de film. Un élément porteur (61) comprenant une base (80) et un couvercle (81) est pourvu d'un canal (83) pour des bandes de film (50). La base et le couvercle peuvent s'assembler par des cliquets pour extraire ou insérer des bandes de film. Une pluralité d'entailles (78) sont associées à chaque cadre (76) pour assurer un positionnement précis de la bande de film.
摘要:
A holder (10) for photographic slides which is normally in a rectilinear condition in which it can be contained in a box. The holder includes a flexible element (12) which has connecting portions (18, 20) at each end thereof. A tongue (28) associated with the portion (18) co-operates with a tongue associated with the portion (20) and the portion (18) co-operates with a flange (34) to secure the holder into the form of a closed loop. A unit (14) is attached to the element (12) and to the portions (18, 20) and forms a series of pockets (54) each of which serves to receive a photographic slide. From the holder (10) the slides are transferred directly to the pockets of a slide magazine for projection. The holder (10), when straight, occupies less space that a rotary projector magazine and is far less expensive to produce.
