FIELD OF THE INVENTION
The present invention relates to improvements in video production
and more particularly to digital video editing.
GLOSSARY OF TERMS USED
For proper description of the proposed method a definition of terms
used in the present disclosure is given. These terms are based on the
Glossary of Class 358 (Television) of the United States Patent Classification.
Frame - a static visual information of determined volume, fixed on any carrier
of the information.
Pixel - smallest distinguishable and resolvable area in a frame, with help of
which is determined volume of the information in the frame.
Row - an area in a frame, equal to set of pixels, located on one horizontal
line.
Video - a dynamic visual information, submitted as a sequence of the
frames.
Analog video - a video, submitted with the help of an electro-magnetic
signal.
Digital video - a video, submitted with the help of digits.
Videoediting - a process of creating secondary video from primary video by,
either changing of one video, or connecting of several videos, or changing
and connecting several videos.
Smallest videoediting unit - a unit of measurements of video, with the help
of which are defined the volume of a video or coordinates of the beginning
and the end of a video.
Plan of videoediting - a plan for the creation of the secondary video, in
which the author defines the transfer order of the primary video(s) with the
instructions of required changes in it (them).
Linear videoediting - videoediting, carried out in the same order, as the
transfer order of the primary video(s).
Non-linear videoediting - videoediting, carried out in any order.
Digitising - a process of transforming of an electro-magnetic signal
into digits. In this process each pixel of the image is represented as a
numeral which depends on the color, or hue, saturation and brightness
thereof. These numerals are recorded consecutively, each frame and each
row thereof being determined by a different set of numerals, the number of
said numerals in each set remaining constant. This rule makes possible to
transform the coordinates of a pixel in a frame and the number of the frame
into a numeral N = (FN - 1)(RC)(PC) + (RN - 1)(PC) + (PN), wherein N -
the sequential number of a pixel or a numeral, representing it, in video; FN -
the sequential number of the frame; RC - the number of rows in a frame; PC
- the number of pixels in a row; RN - the sequential number of the row in the
frame; PN - the sequential number of the pixel in the row. The free access to
any pixel in digital video in any given moment allows to edit the digital video
in non-linear mode. Contrary to this the analog video is editable in linear
mode only because in the analog video the sequence of the primary video
elements is not rearrangable without creating the primary video anew.
BACKGROUND OF THE INVENTION
Among the known techniques disclosed for the field of the present
invention the following should be mentioned:
Method and apparatus for generating operation and operand databases and
for employing them in the color image processing, EP patent No.94300002.
Method and apparatus for electronically processing and rerecording
recorded video signals, PCT application No. PCT/EP86/00385.
The disclosures in the above documents have a common drawback:
the frame editing method is employed that is widely used in cinema and
analog video but does not allow to make use of the advantages of the digital
video. Said method allows to change the coordinates of an object in a frame
while the sequence of pixels within the frame remains unchanged.
The functions of the proposed invention can be at least in part
accomplished by non-linear video editing systems described in: System for
non-linear video editing, US patent No.5539527. These systems are here
taken as the state-of-art because they are polyfunctional and efficient.
Nevertheless they have the drawback of being empirical and lacking the
methodology of selecting the smallest videoediting value.
With known methods video editing was effected by the method
wherein the smallest videoediting value was a single frame. This method did
not provide for freely chosing the sequence of the pixels in frame of the
edited video.
The present invention seeks to provide a method for freely chosing
sequence in the edited video not only of frames but also of separate pixels
and regions thereof. In other words the proposed method is characterized in
that the smallest videoediting value is not a frame but a pixel, that is, the
editing parameters relate not to a whole frame but to separate pixels or
regions thereof. The pixel coordinates include not only the row number in
frame and pixel number in row but also the frame number in video.
The known methods of videoediting employ the following coordinates
for frames: HH:MM:SS:FF, where HH is the Hour Number, MM is the Minute
Number, SS is the Second Number and FF is the Frame Number.
The method of the present invention employs the following
coordinates for pixels: HH:MM:SS:FF:RRRR:PPPP, where the additional
coordinate RRRR is Row Number and PPPP is Pixel Number. For example,
address 00:00:00:00:0000:0000 gives coordinates of the first (the extreme
left) pixel in the first (the upmost) row of the first frame of the first second,
first minute, first hour of the video, that is, the first pixel of the video.
For the realization of the proposed method a system of non-linear
editing (Fig. 1) is used. Said system includes a computer system with
memory unit (1) capable of storing the digitized video data, a display (2) with
appropriate resolution and color palette values, video image source (3) and
processor or video controller (4) for joining the computer system with video
image source. The computer system is controlled by a standard operating
system supplemented with an original copyrighted software, developed by
the author of the present invention and not further disclosed herewith.
The proposed method of video editing is a method of nonlinear
videoediting, comprising defining of volume and coordinates of a beginnings
and an end of the video with the help of the smallest videoediting unit and
creation of secondary video, from primary video, characterized with: - as the
mentioned smallest videoediting unit is use pixel; - volume of frames of
mentioned video is determined with the help of the mentioned pixels; - the
mentioned pixels is included into the mentioned secondary video in any
given order; - the order of inclusion of mentioned pixels into the mentioned
secondary video is defined with the help of coordinates of these pixels.
The proposed method allows videoediting in the known modes and
use known effects as well as work in new modes and employ both bi- and
tridimensional special effects with the use of lower resources compared to
known methods or provide unique effects not possible before. The use of the
method of the present invention allows to produce the edited image without
loss of image quality because in contrast with the other methods the
separate pixels or regions of the image are not changed, the change involves
only coordinates thereof. The proposed method of video editing makes use
of the advantages of the digital video where the advanced features of digital
information storage when employed together with contemporary methods of
video editing advantageously extend the possibilities of said methods.
The following examples serve for the better understanding of the
present invention.
EXAMPLE 1
The accompanying program (US copyright #TXu000802493) with digital
video demonstrates the vortex effect on the image of human head. The separate
phases of the effect are shown in Fig. 2: Fig. 2A - the top of the head starts
spinning; Fig. 2B - the spinning top starts dragging along the following lower
section of the head; Fig. 2C - the top sections continue spinning and involve
in the movement the next section; Fig. 2D - the head is in the vortex and
resembles a spiral. This example video spectacularly demonstrates the
positioning of the separate regions of the image in the newly created
(secondary) video in an arrangement (sequence) differering from that in the
primary video, namely with a delay equal to the address value of the
corresponding region. This results in an illusion of a relative mutual
displacement of separate regions of the image.
EXAMPLE 2
In the video advertising a drink the following effect is used. To take
the glass on the right side of the image the human hand positioned on the
left side of the image extends to the glass for a distance significantly
exceeding the real length of a hand. Said stretching effect is realized as
follows. 1 - the extreme right part of the hand starts moving to the right; 2 -
the extreme right part of the hand keeps moving right while giving the
impression of dragging forth the next part being to the left; 3 - the right part of
the hand keeps moving forth and drags on the left part of the hand; 4 - the
hand extends in full and takes the glass. This effect is produced by
positioning of separate regions of the image in the newly created (secondary)
video in an arrangement (sequence) differering from that in the primary
video, namely with a delay equal to the address value of the corresponding
region. This results in an illusion of a relative displacement of separate
regions of the image.

ABSTRACT
The present invention provides a method for freely chosing the
sequence in the edited video not only of frames but also of separate pixels
and regions thereof. The smallest videoediting value is not a frame but a
pixel, that is, the editing parameters relate not to the whole frame but to
separate pixels or regions thereof. The pixel coordinates include not only the
row number in frame and pixel number in row but also the frame number in
video.
