Abstract:
An illumination subsystem, a film guide subsystem, and an imaging subsystem are combined to form an optical system for a film conversion device which projects an image recorded on film onto the at least one optical sensor. The illumination subsystem comprises a lamp. The film guide subsystem comprises a film guide wide enough to support film moving thereover and having an aperture that permits passage of light from the lamp through the film. The imaging subsystem comprises an imaging lens and an optical sensor situated so as to receive the light passing through the aperture and the film. The three subsystems together have an optical path that is folded substantially into the shape of a “U”. This folded arrangement is achieved by placing optical beam bending elements in the optical path of the film conversion device between the illumination subsystem and the film guide subsystem, and between the film guide subsystem and the imaging subsystem. This folded arrangement of the components of the optical system permits the components of the illumination subsystem and the imaging subsystem to be mounted back-to-back on the same support structure within the film-to-video module. Consequently, the optical system requires less space than is required without the folding of the optical path.
Abstract:
A scheme for obtaining an original image free from any dust or scratches on a film by scanning a film original or the like with visible light and infrared light has been proposed. This scheme suffers problems, i.e., a large memory size and long processing time since original image data obtained by infrared light must be stored. To solve such conventional problems, this invention provides, e.g., an image scanning apparatus which has a light source for emitting visible light and invisible light, scanning means for scanning an original image irradiated with light emitted by the light source, and control means for controlling the scanning means to scan the original image irradiated with the invisible light, and then to scan the original image irradiated with the visible light.
Abstract:
A film scanner performs a main-scan of a film by an imaging device and performs a sub-scan of the imaging device so as to enable scanning at any resolution using a simple configuration. The scanning mechanism, for the sub-scan of the film with respect to the imaging device, has a transport table for supporting the film held by a film holder and transporting it in a sub-scan direction and a transport mechanism for moving the transport table in the sub-scan direction. The source of the drive power of the transport mechanism is a scan motor (stepper motor) driven by a pulse signal output from a motor drive circuit. The motor drive circuit is configured to enable micro-stepping of the scan motor.
Abstract:
Methods and systems for recognizing a film in a scanner are provided. First, the film is previewed by the scanner to obtain an original preview image. The original preview image comprises a film image corresponding to the film. The original preview image also comprises pixels and each pixel has a first hue value, a second hue value, and a third hue value. The pixels with luminance in a predetermined range are then selected from the original preview image to acquire a second preview image. Next, the second preview image is framed according to the first hue values of the pixels to obtain an image frame. Finally, the image frame is sectioned to recognize the film image.
Abstract:
A reconfigurable digital processor to improve efficiency and flexibility in film conversion applications is described. Analog signals corresponding to film images are digitized and provided to the reconfigurable digital processor. The reconfigurable digital processor uses programmable circuit elements, such as field programmable gate arrays and digital signal processors, to perform film conversion functions. The number of programmable circuit elements can be scaled in proportion to cost or desired throughput rates, thereby offering a variety of cost-efficient film conversion devices for varying needs. The reconfigurable digital processor provides one or more outputs which are formatted to produce one or more digital motion picture files in parallel. The reconfigurable digital processor can be altered using software codes at any time to perform different film conversion functions and adapt to changes in format of digital motion picture files.
Abstract:
A cost-efficient digital parallel processor to improve throughput and offer a variety of output formats in film conversion is described. Image pixels on film are translated into electrical signals by photosensitive detectors. The electrical signals are digitized by analog-to-digital converters and thereafter provided to a digital parallel processor for film conversion functions. The digital parallel processor includes two or more groups of circuit elements to facilitate parallel processing. Each group of circuit elements can process a different set of image pixels simultaneously. In addition, image pixels belonging to the same set can be processed in parallel. This two-dimensional parallel processing structure facilitates faster than real-time film conversion sessions. A supervisor control circuit monitors and controls the sequence of film conversion functions. The output of the digital parallel processor is provided to a formatter which manipulates the data to conform to one or more standard formats. The data in different standard formats can be provided in parallel, thereby eliminated the need for additional film conversion sessions. The data in standard formats can be stored in local memory, written to a storage medium, provided to another device for further processing, or converted by a digital-to-analog converter for display on a video monitor.
Abstract:
A photographic and video image system for transforming an image on a frame of a photographic film includes a structure in the overall form of a photographic printer having an image transformation element that transforms an optical image from the film into a video signal, a frame position indicator, which can be a hole or an optical or magnetic signal, is recorded on the film along with aspect information relating to the size of the frame exposed on the film. The frame position indicator and aspect information are detected and used to control a film feeding operation and the optical image to video signal transformation operation. The user of the system can record order information on the film that is used to specify the aspect of the resultant photographic print, as well as the quantity of prints to be made. Such order information can be superimposed as a menu on a displayed video signal at the time the video signal is reviewed prior to producing a photographic print.

Abstract:
The image processing method sets an image processing condition of an image using either image data of an image clipping area corresponding to the image or extended image data which is image data of an extended image area that is wider than the image clipping area in a direction in which a plurality of images is continuously recorded; represents an image obtained by processing the extended image data in accordance with the image processing condition and the image clipping area or only an image within the image clipping area obtained by processing said extended image data in accordance with said image processing condition; judges whether the represented image clipping area is appropriate or not; and modifies the image clipping area in accordance with a result of the judging. Even when a frame clipping error occurs in a photoprinter, the method can consistently output an appropriate image preventing decrease of work or production efficiency or keeping it to a minimum.
Abstract:
A digital processor to synchronize ancillary information with film images during a film conversion session is described. The ancillary information includes metadata information and audio information. The digital processor advantageously processes the ancillary information at a speed to support faster than real-time film conversion. The ancillary information can come from various sources and in various forms. Information from analog sources is digitized for processing using digital technology. A pitch adjuster frequency shifts digitized analog signals and digital input signals to achieve a selected data rate that matches the rate of film conversion. Digitally encoded input data can be decoded and re-encoded to achieve the selected data rate. A formatter manipulates the ancillary information at the selected data rate to conform to a standard format and combines the formatted ancillary information with film images conforming to a standard motion picture format.
