Abstract:
An electronic camera (20) operates with a small, portable computer (10) having a card interface (12, 22) of the type used for communicating with a removable memory card. The camera includes an image sensor for converting an image into an electrical signal, an A/D converter for converting the electrical signal into a digital signal, and a signal processor for interfacing the digital signal to the card interface (22), ordinarily a slot (16) receptacle, on the computer. By defining the interface to include a mechanical extender (24) that physically interconnects the camera to the card slot (16) on the computer, the camera and computer are linked in a high speed interface as a convenient, hand-held unit.
Abstract:
A digital camera (10) is disclosed for capturing digital images and organizing the captured images for subsequent transfer from the digital camera to an external device (40) that utilizes the digital images. The digital camera includes a database having a plurality of customized profiles, wherein each customized profile contains a plurality of image utilization fields. A user selects one of the plurality of customized profiles from the database. The digital camera further includes a structure for defining a plurality of profile indices respectively corresponding to ones of the plurality of customized profiles, and an image sensor for capturing images. A profile index is associated with at least one captured image to identify the corresponding selected customized profile. The digital camera further includes a memory for receiving and storing the at least one captured image and the corresponding profile index.
Abstract:

Abstract:
An electrostatic information recording medium (3) composed of an electrostatic information recording medium electrode (13) and a charge holding layer (11) put thereon, wherein the layer (11) is formed from a fluororesin composed of repeating ring structure units of general formulae (1) and/or (2) and having such a molecular weight as to give an intrinsic viscosity of at least 0.1 at 50 °C, wherein n is 1 or 2. The above constitution serves to hold persistently the information charges stored in the charge holding layer. Because the information storage means is an electrostatic charge unit, the information stored in this recording medium has a high quality and a high resolution, the information processing is simple, a long-term storage is possible, and the stored information can be reproduced arbitrarily and repeatedly with an image quality meeting the purpose of use.
Abstract:
A method of calibrating an incoherent optical fibre bundle to be used for image transmission, by determining the relative input to output position of each fibre in the bundle and processing the light output of the bundle accordingly. The calibration technique comprises, defining an address array capable of defining for the optical bundle the position of the ends of individual optical fibres in the bundle; transmitting a series of test images into one end of the optical fibre bundle, each test image illuminating a substantial proportion of the pixels and the combination of which selectively illuminate each pixel of the address array; analysing the output of the fibre bundle with reference to the transmitted images to produce a reference table of input to output for the fibres; and using the reference table to deconvolve an image transmitted along the fibre bundle. Calibrated incoherent optical fibres are of particular use for examining nuclear reactors, chemical vats and other harsh environments.

Abstract:
In an image forming method of receiving encrypted data generated by an information processing apparatus, decrypting the encrypted data into data to be printed, and causing an image forming apparatus to execute printing processing, print data is acquired by decrypting the received encrypted data, and the acquired print data is converted into image data for which the printing processing can be performed. The image data is encrypted with first key information.
Abstract:
A film video player apparatus for sensing a film frame image to produce a standard video signal includes an optical device (248) for selectively changing the magnification of the film image with respect to the video display (zoom), a device (252) for displacing the film image horizontally and vertically with respect to the video display (scan), and a control system (202) for coordinating zoom and scan so that the video display is always filled with the film image.
Abstract:
A method for transmission of a sequence of high quality images for display on a visual display unit is described. It has particular application in the field of telepathology, where magnified images obtained by scanning a medical specimen on the stage of an optical microscope are transmitted from a local pathologist to a remote consultant for diagnosis. The method consists of the steps of advancing the field of view of the camera in discrete steps across the object being viewed to capture a sequence of contiguous images, temporarily storing a digital representation of a first of the images in a first buffer store and a digital representation of at least part of the next succeeding image in a second buffer store, controlling the data in the two buffer stores such that the data follows the leading edge of the advancing viewport and data in the first store representing a trailing incremental strip of the first stored image is progressively discarded while data in the second store representing a trailing incremental strip of the next contiguous image is transferred to a location in the first store occupied by the data representing leading incremental strip of the first stored image, and reading out the contents of the first buffer store to the display unit.
Abstract:
The invention relates to a reader comprising a projection device for projecting of light emitted from a radiation source (117) to a section of a marked surface (20) and an optical unit (4) for receiving and visualising the reflected light on an image sensor (114) which transforms the reflected light into a sequence of electronic signals. The reader also has a motion detector (2) for generating synchronisation signals during movement parallel to the marked surface, and also a signal processing unit which converts the signals of the image sensor into information packets containing independently of the character code the alphanumerical, graphic or pictorial information of a freely selectable part of the marked surface, and stores said signals in a memory unit from which they can be retrieved.
