Inventor: TAKASHI TORIU
IPC: G06T7/20

Abstract: A moving video image estimation system is provided, in which, when a video image occurring at an arbitrary time t between time n and time n + 1 or at an arbitrary time t after time n + 1 is produced for time series video images given at discrete times 1, 2, ... n, n + 1, ..., even if the position and shape of an object in the video image are considerably changed between the frames, the video image of the object in the original frame can be prevented from being reproduced doubly in the interpolated video image. 
     Based on an original video image of time n and time n + 1 , the centroid, the principal axis of inertia, the moment about the principal axis of inertia and the moment about the axis perpendicular to the principal axis of inertia are obtained. By using them, an affine transformation for transforming the original video image at time n to the original video image at time n + 1. Further, based on the infinitesimal transformation (A), {exp (At), and exp(A (t - 1))} obtained by making the affine transformation continuous with regard to time is executed on the original video image at time n and time n + 1. The results are synthesized to perform an interpolation between the frames. {exp (A (t - i))} is applied to the original video image at time n + 1, the video image after time n + 1 is predicted.

Abstract: A video signal recording apparatus having luminance and chrominance signals multiplexed on a time division basis. In signal recording, a two-channel head arrangement (10A, 11, 17A; 10B, 11,17B) with a gap between different azimuths performs two scans on one field of recording signals for two tracks concurrently. Because the same kind of chrominance signal is subject to each of the different azimuths, not only normal speed reproduction but also variable speed reproduction is performed with high picture quality.

Abstract: There is provided a method for detecting change points between cuts from motion picture images including a plurality of consecutive images. First of all, in this method, motion picture images which are the subject of detection of change point between cuts are inputted (21) in a time series by taking a frame as the unit, and a predetermined feature quantity including a color histogram possessed by image data of said motion picture images is produced (22) while taking a frame as the unit. A correlation coefficient with respect to feature quantity between the above described feature quantity and a feature quantity produced in an immediately preceding frame is then produced (23). Further, a change rate between the correlation coefficient of the current frame and a correlation coefficient produced for a frame preceding the current frame is produced (24). A time point whereat the change rate exceeds a predetermined allowable value is detected (25) as a change point between cuts of the motion picture images.

Abstract: A cellular radio telephone (5) has two (or more) telephone numbers (TN1....TNN), specifically for example an office telephone number and a private telephone number. In one mode of operation both numbers are operable concurrently. However, in a second mode one of the numbers may be disabled by the user, e.g. using a menu selection facility on a visual display (55). In the first mode, the telephone number of an incoming call is shown on the display (55) so that the user can know which number the call is intended for before answering it. Preferably one of the telephone numbers may be selectively enabled for outgoing calls, again by menu selection. As a consequence all of the other telephone numbers may be automatically disabled for outgoing calls in both modes of operation.

In each information processor, the same data added (101, 201, 301) with a cyclic redundancy code is subjected to a predetermined masking process (102, 202, 302) and is thereafter encoded on the basis of a cyclic logical shift. A logical product or exclusive OR combination of encoded data from the information processors is made and is subjected to an inverse cyclic logical shift for decoding into an original data. By displaying the decoded data on a display device or the like, the original data becomes identifiable since a character having a meaning is displayed if the decoded data is normal and a character not clear in meaning is displayed if the decoded data is abnormal.
