Abstract: An image processing apparatus receives an image signal and generates a display image having an image range associated with a display area of a display unit from an image based on the image signal. The image processing apparatus includes a position-of-interest-calculating-unit, a frame-out-accuracy-calculation-unit, an alteration-variable-decision-unit and an image-alteration-unit. The position-of-interest-calculating-unit calculates a position of interest as a position of an object of interest in the image. The frame-out-accuracy-calculation-unit calculates a frame-out accuracy representing an accuracy that the position of interest deviates from the image range based on the position of interest and the image range. The alteration-variable-decision-unit decides a processing variable of alteration processing performed with respect to the image in conformity with the frame-out accuracy.

Abstract: The present video tracking technique outputs a Maximum A Posterior (MAP) solution for a target object based on two object templates obtained from a start and an end keyframe of a whole state sequence. The technique first minimizes the whole state space of the sequence by generating a sparse set of local two-dimensional modes in each frame of the sequence. The two-dimensional modes are converted into three-dimensional points within a three-dimensional volume. The three-dimensional points are clustered using a spectral clustering technique where each cluster corresponds to a possible trajectory segment of the target object. If there is occlusion in the sequence, occlusion segments are generated so that an optimal trajectory of the target object can be obtained.

Abstract: A developed photographic film including a magnetic layer is transported up to an image reading part so as to read a film image thereon. The film images are sequentially displayed on a TV monitor in accordance with automatic regenerating information. The automatic regenerating information is previously input as information used for sequentially and automatically regenerating a plurality of the film images. Moreover, magnetic information is used as a part of the automatic regenerating information. This magnetic information is recorded in the magnetic layer by a camera at the time of photographing. As a result, an operation is simplified at the time of inputting the automatic regenerating information.

Abstract: A film image reproducing apparatus comprises a chamber which receives a film cartridge holding a film with a magnetic recording section. A frame position detector detects a position of a frame of the film with the magnetic recording section in which an image formation is finished. The film with the magnetic recording section is transferred from the cartridge, which cartridge is in the chamber, and film transfer is stopped based on an output of the frame position detector. A reader reads recording data from the magnetic recording section while the film is being transferred. A projector projects light on the film while the film is stopped. A photoelectric converter converts a projection image of the film projected by the projector into an electrical signal. A synthesized image is reproduced from an output of the reader and from an output of the photoelectric converter.

Abstract: A system and method to improve the quality of reproduced images on a film to video transfer device by scanning extra lines to reduce vertical aliasing and performing vertical sample rate reduction to produce the correct number of video output lines High frequency noise is reduced as a result of the vertical sample rate reduction which produces a line filtering. More lines are scanned than normal and the distance between lines is reduced so that the larger number of lines covers the original film image area. This has the effect of increasing the sampling frequency in the vertical direction and therefore reducing aliasing. To provide the correct number of lines in the output of the film to video sample, rate reduction is performed. Sample rate reduction is performed by filtering multiple adjacent lines to remove any high frequency content that would be aliased at the lower rate. Lines are discarded in a predefined sequence that is a function of the fractional reduction rate.

Abstract: Film unsteadiness in a flying spot film scanner (10) is measured by reference to film image movement based on a measure of the direction of movement acquired by examination by a movement compensator 30 of spatial and temporal differences around a given pixel. A correction signal is generated and applied as a feedback signal to the X and Y circuits of the scan generator (20).

Abstract: Digital signals are generated and stored for each pixel of a frame of a preferably high definition video originated material. A computer reads the digital signals and converts them to binary image data by employing a selected look-up-table program to reassign color and black component values for each pixel. The programs applied in the component value reassignments are compiled from, and based on, comparative digital video component results of telecined film stocks' responses to selected color and grey scale gradients as charted against a selected video unit's response to the same charts under a selected number of identical lighting circumstances. A projector unit projects the high definition video frame through a macro lens onto a strip of exposed and processed motion picture or other photographic film of an optional grey scale gradient and thus grain pattern density.

Abstract: To avoid the effect of blemishes in a CRT phosphor of a CRT film scanner a map is produced identifying areas of the phosphor that are blemished. When a line scan traverses a blemish the signal produced by that scan is inhibited and the area of film is rescanned with the film in a different position relative to the scanner.

Abstract: Compensation for phosphor burn in a CRT scanner is achieved by offsetting the scan by half a line spacing on alternate scans when the film is stationary in the scanner. To avoid unpleasant effects the offset scan output is supressed and the previous frame output frozen in the frame store 24. The previous frame is output again from the frame store in place of the offset scan output.Offset scanning is not performed when a control adjustment is made to avoid a juddering effect on the displayed output.
