Abstract: Disclosed is a video signal processing apparatus including a telecine conversion signal detecting unit configured to detect whether or not an input video signal in an interlaced system is a telecine converted video signal; an IP converting unit configure to convert the input video signal into a signal in a progressive system according to a detected result obtained by the telecine conversion signal detecting unit; and a noise level detecting unit configured to detect a noise level of the input video signal. The video signal processing apparatus further includes a control unit configured to control a detection sensitivity of the telecine conversion signal detecting unit such that the input video signal is detected as the telecine converted video signal less easily if a noise level is increased based on the detected result obtained from the noise level detecting unit.

Abstract: Systems and methods are presented for processing three-dimensional (3D or 3-D) or pseudo-3D programming. The programming includes closed caption (CC) information that includes caption data and a location identifier that specifies a location for the caption data within the 3D programming. The programming information is processed to render the caption data at the specified location and to present the programming on the display. By encoding location identification information into the three-dimensional programming, a high level of configurability can be provided and the 3D experience can be preserved while captions are displayed.
Abstract: A lighting system comprised of a central controller, a digital communications path, and a plurality of image projection lighting devices (IPLDs) is provided. The IPLDs contain cameras that can capture both visible light and infrared light. Address signals sent from the central controller first address a particular IPLD and then command signals sent from the central controller control an infrared blocking filter to be positioned in and out of a camera optical path of the particular addressed IPLD.

Abstract: A compact film player has a picture reproducing unit and an information reading unit capable of reading a photographing information on each frame of the film. When a developed film is fed in an inlet of the picture reproducing unit in a prescribed direction, a scan mirror scans a picture provided on the film perpendicularly to the feed direction, so that a line sensor takes the picture every line. The line sensor and the scan mirror read two-dimensional pictures provided on the film. When the picture of the frame previously read is on display, the scan of the next frame is effected.
Abstract: There is disclosed a video camera which has a normal moving image sensing mode, and a still image sensing mode for sensing an image on a negative film set in a film adapter attached as a still image. An optical image of a subject is photoelectrically converted into an image signal, and whether or not the subject is a negative film is detected on the basis of a predetermined signal component in the image signal. If it is detected that the subject is the negative film, the still image sensing mode starts while setting signal processing in a negative/positive conversion mode and setting the focal length of the lens system at the wide-angle position.
Abstract: An image input apparatus is provided with an imaging section, a scanner, and a charge accumulation control section. The imaging section includes a line sensor and converts an image recorded on film into electric signals. The scanner mechanically scans the relative positional relationships between the film and the line sensor in an intermittent fashion. The charge accumulation control section controls the timings at which the line sensor starts a charge accumulation operation, and this control is executed in association with the intermittent scanning operation of the scanner.
Abstract: A film image signal generation apparatus, includes: a film displacement device which displaces a developed film which has a magnetic recording layer to an image area; an image signal conversion device which converts an image of a film frame which is opposed to the image area into a first image signal; a magnetic writing device which rewrites old data written in the magnetic recording layer of the film into new data; a data storage circuit which stores the old data and the new data; an image signal generation circuit which generates a second image signal which shows data change information, based upon the old data and the new data which are stored by the data storage circuit; and a control circuit which controls the magnetic writing device, the data storage circuit, and the film displacement device so as to rewrite the old data which is recorded upon the magnetic recording layer into the new data which is stored in the storage circuit, and controls the image signal conversion device and the image signal genera
Abstract: A film holder holds a film original and an image reading device uses the film holder for the purpose of easily changing the frames of the film original. The film holder is provided with a holder main body and an adapter. The holder main body holds the film original and has a plurality of openings that face the images of each frame of the film original. The adapter holds the holder main body so that sliding is possible along a length of the film original and has windows that coincide with at least one of the plurality of openings of the holder main body.
Abstract: A width of a illumination light being transmitted through a film is restricted within a distance between frames of the film. The film is transported to a position where only an area between frames is illuminated after the image of one frame is picked up, and a film transport is stopped. Then, the light is diminished or turned off when any operation is not instructed within a first time. Next, the film is transported in such a manner that a middle part of the frame is positioned below or above a photo detector when any operation is not instructed within a second time after the first time has passed, and the film transport is stopped. Then, a magnetic head is pressed against the film and the film is released from being held between the capstan and the pinch roller.
Abstract: A telecine uses a flying-spot scanner to derive video images from a film. A scan control circuit is used to control the scan of the flying-spot to introduce special effects. Pairs of successive images may be misaligned and a motion vector estimator is used to detect the amount of misalignment. This produces a shift vector for an image stabilizer to shift one of the images of a pair. The motion vector estimator also receives data from the scan control circuit relating to any special effect in the images and corrects the shift vector in dependence on this.
Abstract: In a telecine apparatus for converting a light passed through a film into a video signal comprises a transporting device for transporting the film intermittently, operation of a shutter is controlled so that a light from an irradiating device becomes incident on a solid state image sensing element of odd and even simultaneous exposure and sequential-read out system during a period between a storage starting timing of a signal of an odd field of the solid state image sensing element and a read-out timing of a signal of an even field or during a period between a storage starting timing of a signal of an even field of the solid state image sensing element and a read-out timing of a signal of an even field. Further, operation of the transporting device is controlled such that a timing at which the film is intermittently transported becomes the equal interval.
Abstract: A method for determining which of similar video fields may be excised to enhance video signal compression evaluates parameters of four successive fields denoted 0, 1, 2, and 3. Accumulated differences d(0, 2) and d(1,3) of corresponding pixels in successive frames are generated. In addition a determination is made whether fields 1 and 2 exhibit interlace characteristics. If they do not exhibit interlaced characteristics, a comparison is made of d(0, 2) and d(1, 3). If d(0, 2) is less than d(1, 3) by a predetermined amount, field 2 is excised from the signal stream and a code is generated to condition a receiver to display two of the remaining four fields in a three field interval. Subsequently the latter two fields of the set of 0, 1, 2 and 3 fields, and the next two occurring fields are similarly analyzed.
