A video extractor for a pulse radar apparatus comprises a memory capable of storing a number of words corresponding with the number of range quanta, into which the range interval of the pulse radar apparatus is divided. The rate at which words are shifted in and out of memory corresponds with the counting rate of the range counter of the pulse radar apparatus. A video processor updates the target information in the words in response to video, angular and range data from the pulse radar apparatus...

A video thumbnail for use as an icon of a digital video file and method of generating same. The video thumbnail is preferably a relatively short, low resolution, animated video thumbnail. The video thumbnail is extracted from a preferred sequence of the video file and embedded as a header of the file. The video thumbnail preferably plays automatically, and acts as a pointer to the file and the preferred point within it.

The video airship is a lighter-than-air airship, preferably spherical, including a video display disposed with substantially all of the craft's outer surface, a nearly invisible computerized electric propulsion-control system, speakers, microphones, video cameras, communications systems, and extendible landing gear. A power generation system contained within the airship's interior supplies the energy for it's display, propulsion, flight control and other onboard devices.

Motion compensation as for video compression with motion estimation with either frame mode or field mode by initial prediction of motion mode and when prediction error is small enough truncate motion estimation search.

A method of encoding a video signal representing a sequence of pictures, the method comprising encoding a first picture (or segment of a picture) of the sequence without reference to another picture of the sequence to produce a picture (10) and encoding said first picture (or segment of a picture) with reference to another picture (14) of the sequence to produce a corresponding temporally predicted picture (P4) or segment of a picture.

In compression coding of picture sequences, a measure of picture difference is generated and compared with a picture difference threshold. The comparison is used in selecting between the use of predicted (P-pictures) and non-predicted has an initial value adapted to promote the use of an I-picture at or close to a scene change in the picture sequence, and changes in time in such a manner as to increase the probability of selection of a I-picture with an increase in the time since selection of th...

In a method of providing a video simulation on a computer, parameter selection options (S1-S7) and possible parameter values (I1-I6; F1-F9) are displayed, and are selectable by the user. The outcome of the simulation is determined according to the combination of parameters selected by the user, user interaction during a simulation video clip, and additionally according to a random or pseudo-random determination. An outcome video clip (V) corresponding to the outcome is selected and displayed.

A system and process for generating a panoramic video. Essentially, the panoramic video is created by first acquiring multiple videos of the scene being depicted. Preferably, these videos collectively depict a full 360 degree view of the surrounding scene and are captured using a multiple camera rig. The acquisition phase also includes a calibration procedure that provides information about the camera rig used to capture the videos that is used in the next phase for creating the panoramic video....

A video projector includes a cabinet, and adjusters provided in bottom and top surfaces of the cabinet and located on left and right positions of the bottom and top surfaces close to the front surface of the cabinet. The adjusters are supported by shafts perpendicular to the front surface so as to be rotatable in an angular range of 90.degree.. When the adjusters are postured to be perpendicular to bottom and top surfaces of the cabinet, the cabinet is placed horizontally. When the adjusters are...

A video camera includes an abutment piece which is perpendicularly placed on the anterior side of the bottom of a stand portion and abuts on an attachment body to which the video camera is to be attached, a lever portion which is rotatably attached on the posterior side of the bottom of the stand portion, and bias means for biasing the lever potion toward the bottom of the stand portion. The lever portion includes an abutment portion formed such that it abuts on the abutment body. The lever port...
