Description

  The present invention relates to a video control apparatus, an editing apparatus, and a recording and reproducing apparatus which control a reproduction position of a high frame rate video format.

  Conventionally, in the work of performing video editing in a broadcasting station or a movie production site, indexing information called Time Code (hereinafter referred to as TC) in which a unique number is assigned to each frame of a video signal is used. There is. TC is standardized in SMPTE (Society of Motion Picture and Television Engineers, United States of America Motion Picture and Television Engineers Association) (see, for example, non-patent documents 1 to 3).

Also, a plurality of frame rates are adopted as a video format.
For example, in the case of a movie, movie shooting and display are performed mainly at 24 frames (24 frames per second, hereinafter 24 fps) per second. Further, in the case of a television, it is operated at 60 fps or 59.94 fps in the NTSC format, 50 fps in the PAL and SECAM, and 59.94 fps in the HDTV (High-definition television). These are hereinafter referred to as reference frame rates.
In particular, in a VTR or other video recording apparatus, a TC such as a Longitudinal Time Code (LTC) or a Vertical Interval Time Code (VITC) is adopted and used for video editing and the like.
In addition, techniques for converting and generating TC between these video formats have been proposed (see, for example, Patent Documents 1 and 2).

Furthermore, in recent years, double-speed display displays such as 120, 180 and 240 Hz and 120 and 240 Hz drive imaging devices have appeared.
Also, with regard to the pixel number format of video, the resolution has been increased from 1920 × 1080 HDTV to 3840 × 2160, so-called 4k2k, or 7680 × 4320, so-called 8K, and the screen tends to be larger. For this reason, the coarseness of the time resolution at the time of moving image display becomes noticeable, and in order to improve the time resolution, a video format of high frame frequency such as 96 fps, 100 fps, 119.88 fps, 120 fps exceeding 60 fps is desired. .
For these high frame rate images, a TC compatible with the reference frame rate image has been proposed (see, for example, Patent Document 3).

SMPTE 12M SMPTE 262M SMPTE 309M

By the way, in the case of a video format of 60 fps or less, it has been possible to operate in the conventional TC format in commercial video editing, sound insertion work, synchronous operation of video and audio, broadcast transmission and the like.
For example, in the NTSC or HDTV 525, 1080/60 format, an image of 30 frames or 29.97 frames is displayed per second, and in the interlace format, 60 frames of video per second, odd number A frame composed of scanning lines and a frame composed of scanning lines of even numbers are separately indexed and displayed. At this time, 60 frame numbers per second are assigned to TC in the order of 0f odd / even, 1f odd / even,..., 29f odd / even.

  On the other hand, for video signals represented by a frame rate that is an integral multiple of the reference frame rate, such as 120 fps or 240 fps, when performing synchronous operation or video editing based on the existing TC, in addition to the conventional frame numbers Sub-frames of can be allocated and expressed. The above-mentioned odd frame and even frame can be treated as subframes.

  Therefore, a standard television in NTSC format, a high-definition television (HDTV) with 1080 scanning lines, or an ultra-high-definition television with 2160 or 4320 scanning lines (so-called conventionally used) In Ultra High-Definition Television) called 4K or 8K, images with reference frame rates such as 24, 25, 29.97, and 30 fps mixed with images with high frame rates of integral multiples while maintaining compatibility It is assumed that video editing is performed. Since it is difficult for the video editing operator to identify the correspondence of time axis between the formats when simultaneously handling a plurality of videos with different frame rates, this causes human error in video editing work. , There was a risk that work efficiency would decline.

  An object of the present invention is to provide a video control apparatus that facilitates handling on a subframe basis even in an environment where video material of a reference frame rate and video material of a high frame rate exceeding the reference frame rate are mixed. I assume.

  The video control apparatus according to the present invention is a video control apparatus that performs an operation on a frame basis with respect to a video format of a multiplied frame rate obtained by multiplying a reference frame rate by an integer, and the video format of the multiplied frame rate is As a time code, a frame number of a reference frame and a subframe identifier corresponding to the frame number are added, and a first operation unit instructing return or sending in units of the frame number, and the subframe And a second operation unit that instructs to return or send in units of an identifier.

  The first operation unit and the second operation unit may be jog dials for instructing a return amount or a feed amount according to the rotation operation amount, and may receive rotation operations independent of each other.

  The second operation unit may be disposed concentrically with the first operation unit.

  The second operation unit moves the frame number by one with respect to the operation amount of one rotation, and moves the subframe identifier by one for each angle obtained by equally dividing the operation amount of the one rotation. Alternatively, the feed amount may be indicated.

  The first operation unit and the second operation unit may be buttons for instructing a return amount or a feed amount according to the pressing operation amount.

  The video control device may include a first switching unit that switches an operation on the second operation unit to enable or disable.

  The video control device may include a second switching unit that switches whether or not to operate the first operation unit as the same functional unit as the second operation unit.

  According to the present invention, even in an environment where video material of a reference frame rate and video material of a high frame rate exceeding the reference frame rate are mixed, handling on a subframe basis becomes easy.

A computer that processes (for example, generates and records) video data assigns a unique TC to each frame of the video format in order to time synchronize the video format of a predetermined frame rate.
First, the assignment and presentation method of this TC will be described.

  For example, in the case of a 30 fps video format such as 30 P (30 fps, progressive), TCs of 30 frames of 0 f (Frame) to 29 f per second are allocated. Also, in the case of a 60 fps video format such as 60i (interlaced) or 60P (progressive), 0f-Odd, 0f-Even, 1f-Odd, 1f-Even, ..., 29f-Odd, 29f per second. As in “Even,” TCs of 60 frames in total are allocated assuming that there are two subframes (Odd / Even) for each of 30 mainframes.

  Furthermore, in the case of a video format having a frame rate exceeding 60 fps, a subframe identifier is provided that complements between TCs used in a video format having a frame frequency of 60 fps or less (for example, 60 fps). Thereby, compatibility with the TC used in the video format having a frame rate of 60 fps or less is maintained, and each frame (subframe) is uniquely identified.

FIG. 6 is a diagram illustrating the positioning of frames and subframes in the TC of high frame rate video according to the present embodiment.
In this example, in the case of a moving image captured and displayed at 120 fps, a method of assigning a TC to each frame for synchronous operation, recording, etc. is shown.

  In the case of a 120 fps video format, 120 frames corresponding to one second are first grouped by frame numbers 00 to 29. Then, four subframe identifiers (Odd / Quater / Even / Three-Quarters) including two subframe identifiers (Odd / Even) in the case of 60 fps are sequentially assigned to frame numbers from 0 to 29 respectively. Ru. This assigns a unique TC to all 120 frames per second.

FIGS. 7 to 11 illustrate a method of presenting a TC provided with a subframe identifier according to the present embodiment.
The TC to which the subframe identifier is assigned is expressed, for example, as follows by displaying the subframe identifier as a cyclic or counting up display or a unique character or the like.

  (A) In the display area (for example, a 7-segment display for displaying numbers), segments to be lit sequentially are set on the outer periphery. A set of segments corresponding to each subframe identifier is sequentially turned on in order, for example (upper bar, right bar, lower bar, left bar) (FIG. 7).

  (B) In the display area, pointed characters are set to be displayed sequentially on the circumference. The characters in the direction corresponding to each sub-frame identifier are cyclically displayed in order, for example (upward, rightward, downward, leftward) (FIG. 8).

  (C) In the display area, numerals similar to the frame numbers are sequentially displayed by counting up from 0 or 1 (FIG. 9).

  (D) In the display area, the number of the same characters (for example, dots) sequentially increases and is displayed side by side on the same line (straight line or curve) (FIG. 10).

  (E) In the display area, unique characters corresponding to each subframe identifier are displayed (FIG. 11).

First Embodiment
Hereinafter, a first embodiment of the present invention will be described.
The editing apparatus 1 of the present embodiment is an apparatus for editing the video data to which the above-described TC is assigned.

FIG. 1 is a view showing the overall configuration of the editing apparatus 1 according to the present embodiment.
The editing device 1 includes an operation controller 10 as a video control device, a main unit 20 including a recording medium 21, and a display unit 30.

  The operation controller 10 is an operation unit for designating the position of the video material in units of subframes by the editing operator returning or transmitting the video frame on the time axis.

The main body unit 20 is an information processing unit (computer) that controls the entire editing apparatus 1, and executes software for video editing to receive operation input from the operation controller 10 and record the operation input on the recording medium 21. Editing of the video material being displayed and display control on the display unit 30;
The recording medium 21 includes, for example, an optical film, a magnetic tape, a magnetic disk, an optical disc, a solid state memory, and the like, and is a medium for recording, storing, and reproducing an image.

  The display unit 30 displays, for example, frames of the video material before editing and after editing, various information for editing, etc. when connecting a plurality of video materials and reconstructing as a moving image by display control of the main body unit 20. .

FIG. 2 is a diagram showing the configuration of the operation controller 10 of the editing device 1 according to the present embodiment.
The operation controller 10 includes a high speed jog 11, a low speed jog 12, a high speed return button 13-1, a high speed feed button 13-2, a low speed return button 14-1, a low speed feed button 14-2, and a minute movement jog A minute return button 16-1, a minute feed button 16-2, and a switching button 17 are provided.

The high-speed jog 11 is a high-speed return / feed operation unit (jog dial) for the editing operator to return or send a video frame at high speed (for example, in units of one second) on the time axis.
The low-speed jog 12 is a frame back feed operation unit (jog dial) for the editing operator to return or send a video frame at a low speed on the time axis (for example, in units of reference frames having the same subframe identifier). is there.
When the editor turns the high speed jog 11 or the low speed jog 12 clockwise, the video frame is sent first on the time axis according to the amount of rotational operation, and when it turns counterclockwise, the image returns on the time axis , And video frames are displayed on the display unit 30.

The fast return button 13-1 and the fast feed button 13-2 have the same function as the fast jog 11. That is, when the fast return button 13-1 is pressed, the video is returned at high speed, and when the fast feed button 13-2 is pressed, the video is sent at high speed.
Low speed reverse button 14-1 and the low-speed feed button 14-2 has the same function as slow jog 12. That is, when the low speed return button 14-1 is pressed, the video is returned to low speed, and when the low speed feed button 14-2 is pressed, the video is sent at low speed.

The minute movement jog 15 is provided as a minute movement operation unit (jog dial) in units of subframes on the concentric circle inside the low speed jog 12 in order to independently move the subframes for high frame rate video format.
When the editing operator rotates the micro movement jog 15 clockwise, the image is sent first in subframe units on the time axis according to the amount of rotational operation, and when it is rotated counterclockwise, the image is sub-timed on the time axis. The image frame (subframe) is returned on a frame basis and displayed on the display unit 30.
In the same manner as the low speed jog 12, the minute movement jog 15 may be provided with a notch 151 so that the movement operation with a fingertip can be easily performed.

The minute movement jog 15 may instruct the movement of the sub-frame by one frame number for the operation amount of one rotation. In this case, the sub-frame identifier may be moved by one for each angle obtained by equally dividing the operation amount of one rotation. If the editing operator places the finger on the top of the micro movement jog 15 and rotates clockwise, for example, while the Odd sub-frame of the image of 120 fps is selected, Quater, Even every 90 degrees of rotation. Subframes are moved in the order of, Three-Quarters, and Odd. At this time, the position (direction) of the finger interlocks with the display of the subframe identifier (for example, FIG. 7 or FIG. 8), so that the editing operator can easily grasp the currently selected time position.
Note that when the notch 151 is located at a predetermined position, for example, the upper part, the Odd subframes corresponding to each frame of the reference frame rate may be always selected.

The minute return button 16-1 and the minute feed button 16-2 have the same function as the minute movement jog 15. That is, when the minute return button 16-1 is pressed, the image is returned in units of subframes, and when the minute feed button 16-2 is pressed, the images are sent in units of subframe.
These buttons may indicate movement of one subframe by one press. Further, the configuration may be such that continuous movement can be instructed by long press of the button.

  FIG. 3 is a diagram showing a transition example of video frames displayed on the display unit 30 in response to an operation input to the operation controller 10 according to the present embodiment.

For example, the TC display 311 is "10 o'clock (h) 10 minutes (m) 10 seconds (s) 15 frames (f) Odd sub-frame" when the image 31 at a certain time position is stationary.
The editing operator can move to the image 32 one subframe after next by rotating the micro movement jog 15 clockwise or pressing the micro feed button 16-2 once, at which time the TC display is performed. 321 is "10 o'clock (h) 10 minutes (m) 10 seconds (s) 15 frames (f) Quarter subframe".
Similarly, when returning to the previous sub-frame, the editing operator rotates the minute movement jog 15 counterclockwise or presses the minute return button 16-1 once to set “10” of one subframe before. The time (h) can be moved to 10 minutes (m) 10 seconds (s) 14 frames (f) Three-Quarters subframes.

  Also, the editing operator can move to the image 33 one frame ahead by rotating the low speed jog 12 clockwise or pressing the low speed feed button 14-2 once. The TC display 331 at this time is “10 o'clock (h) 10 minutes (m) 10 seconds (s) 16 frames (f) Odd subframe”. Similarly, the editing operator can move to the image one frame before by turning the low speed jog 12 counterclockwise or pressing the low speed return button 14-1 once.

Furthermore, the editing operator can return the frame at high speed by operating the high speed jog 11, the high speed return button 13-1, or the high speed feed button 13-2.
In the case of low speed or high speed movement, the main body unit 20 may send back the video frame so that the sub-frame identifiers become the same, or may send back so as to always select the Odd sub-frame.

The switching button 17 is a button for switching the state of function assignment to each of the operation units for micro movement or low speed movement.
Specifically, the switching button 17 selectively switches one of the following states.

  (State 1) The operation on each operation unit described above becomes valid (active). That is, return feed is performed in units of subframes by operation of the micro movement jog 15, the micro return button 16-1, and the micro feed button 16-2, and the low speed jog 12, the low speed return button 14-1, and the low speed feed button 14-. As a result of the operation of 2, the back feed is performed in frame number units.

(State 2) Operations on the micromotion jog 15, microreturn button 16-1, and microfeed button 16-2 become invalid (inactive), and the low speed jog 12, the low speed rewind button 14-1, and the low speed feed button 14-2 As a result of the operation, back feed is performed in units of subframes.
Alternatively, with respect to the operations of the low speed jog 12, the low speed return button 14-1, and the low speed feed button 14-2 while the operations on the micro movement jog 15, the micro return button 16-1, and the micro feed button 16-2 are valid. , And are performed in units of subframes. That is, both the small movement and the low speed movement have the same function of movement in units of subframes.

(State 3) Operations on the micromotion jog 15, the microreturn button 16-1, and the microfeed button 16-2 become invalid (inactive), and the backfeed operation in units of subframes is prohibited.
In this case, even for high frame rate video having subframes, only the first subframe (eg, Odd subframe) is adopted, and other subframes (eg, Quarter subframe, Even subframe other than Odd subframe, etc.) Three-Quarters subframes) are ignored. The editing operator can easily create the edited video at the reference frame rate by automatically thinning out the sub-frames when the frame rates are mixed.

  The switching button 17 sequentially switches the above states 1 to 3 each time the switching button 17 is pressed. At this time, the operation controller 10 lights, for example, the switching button 17 itself or an indicator in the vicinity in orange when in state 1 (active mode), and in green when in state 2 (inactive mode 1), In the state 3 (inactive mode 2), the light is turned off to notify the editing operator of which state it is.

  The switching button 17 may be configured by a plurality of buttons for switching to the states 1 to 3 respectively. Further, it may be configured to include one or both of an operation unit (first switching unit) that switches between state 1 and state 3 or an operation unit (second switching unit) that switches between state 1 and state 2 .

  FIG. 4 is a view exemplifying a video editing method in the case where video materials of different frame rates are mixed by the editing device 1 according to the present embodiment.

  On the display unit 30, for example, a screen (M) for presenting the editing material A or B and a screen (N) after editing are displayed together with the TC. Also, on the video material roll drawn together with the time axis, the division of the material A or material B in the edited video, and the correspondence between the time position in the edited video and the time position in the material A or B Is displayed.

More specifically, in this example, the reference frame rate video (30 fps video, here moving image A) and the high frame rate video (120 fps video equivalent to 4 ×, here moving image B) are different. There are mixed video formats.
It is assumed that the editing operator connects videos of two different formats and creates edited video of, for example, 3 minutes and 0 seconds and 0 frames in the format of the reference frame rate (30 fps video).

First, it is assumed that the operation controller 10 is set to the state 1 (active mode) by the switching button 17.
Since the moving image A is a reference frame rate image, there is no image divided into sub-frames, and if sub-frames are tentatively assigned to any frame position, all correspond to the same sub-frame position (Odd) Do. For example, if the TC is an image at the start time position of "10 o'clock (h) 10 minutes (m) 10 seconds (s) 15 frames (f)", adopting an image for 1 minute 30 seconds 15 frames from this frame The TC at the image end position is “10 o'clock (h) 11 minutes (m) 40 seconds (s) 29 frames (f)”.

After that, from the time position of the start TC “10 o'clock (h) 20 minutes (m) 30 seconds (s) 11 frames (f) Odd sub-frame” at the reference frame rate from the moving image B of different frame rates When it is going to connect 1 minute 29 seconds 15 frames, the editing operator is until the time position of the end TC “10 o'clock (h) 21 minutes (m) 59 seconds (s) 25 frames (f) Odd subframe” Ignore and edit the Quarter subframe, the Even subframe, and the Three-Quarters subframe of No.
At this time, the editing operator can handle the frame numbers in the same manner for the moving image A and the moving image B during the operation. For the sub-frame, the editing operator aligns the character symbolically indicating the sub-frame identifier (here, the direction of the peak) using the micro movement jog 15, the micro return button 16-1, or the micro feed button 16-2. You can easily edit it.

  In this sub-frame position determination, the editing operation is performed in combination with the high speed jog 11, the low speed jog 12, the high speed return button 13-1, the high speed feed button 13-2, the low speed return button 14-1, or the low speed feed button 14-2. The person can move the sub-frame position precisely by using the micro-movement jog 15, the micro-return button 16-1, or the micro-feed button 16-2 when changing the sub-frame start position. Therefore, editing of video material in which frame rates are mixed becomes easy.

  Even when the state 2 (inactive mode 1) is selected by the switching button 17, the editing operator can use the low speed jog 12, the low speed return button 14-1, or the low speed feed button 14-2 to perform the same sub-frame. Operation with precision is possible.

  Also, when state 3 (inactive mode 2) is selected by the switch button 17, the editing device 1 starts the first subframe of the start frame number (for example, Odd) to the first subframe of the end frame number (for example, Since up to Odd) is automatically adopted, the editing operator can easily perform editing work in this case as well.

  Thus, for example, when connecting a high frame rate video to the reference frame rate video on the time axis, the editing operator can count the frame numbers with the same concept as the reference frame rate video, so Easy and efficient editing.

  On the other hand, it is assumed that, in the high frame rate video of 120 fps described above, 0 to 119 are simply allocated and edited for indexing of TC frames without applying the concept of subframes in the present embodiment. At this time, if you try to edit to connect the same 1 min 29 sec 15 frames from TC “10 o'clock (h) 20 min (m) 30 sec (s) 11 f Frame rate video from start TC "10 o'clock (h) 20 minutes (m) 30 seconds (s) 44 frames (f)" to end TC "10 o'clock (h) 21 minutes (m) 59 seconds (s) 100 frames (F) ”, it is called in the high frame rate video that 1 min. 29 seconds and 57 frames ahead are connected. Therefore, the correspondence between the frames of both video materials can not be made with the frame numbers, and the editing work becomes complicated.

For this reason, for example, assuming one joint editing work, when one person in charge of editing operation and a program director instructing editing or a person in charge of sound effect input work jointly in one editing room, unique for each video material The word “飛 び” will fly around, causing mis-editing and reducing work efficiency. Furthermore, the editing work becomes more complicated when the video format is not only a fixed multiple (here, four times) of the reference frame rate, but a plurality of video formats such as three times, five times and six times are mixed.
In addition, even if it is assumed that edited video is to be created in a high frame rate video (120 fps video) format, it is necessary to complement and edit frames of the reference frame rate video, so various frame numbers are called May fly during editing work as well, causing misediting or a reduction in work efficiency as well.

  According to the present embodiment, the editing apparatus 1 is provided with a micro movement jog 15 for instructing the return or the feed in the sub frame identifier unit separately from the low speed jog 12 for instructing the return or the feed in the frame number unit. Therefore, even in an environment in which the video material of the reference frame rate and the video material of the high frame rate exceeding the reference frame rate are mixed, the editing apparatus 1 moves both video materials on the same time scale in frame number units. Since it can be finely adjusted in units of subframes, handling in units of subframes is facilitated.

In addition, since the low speed jog 12 and the small movement jog 15 independently receive the rotation operation, the editing operator can easily and freely feel the video data by the jog dial arbitrarily in frame number units or subframe units. It can operate.
Furthermore, since the micro movement jog 15 is arranged concentrically inside the low speed jog 12, the editing operator can easily perform the frame back feed operation on the image in the same movement as the frame number unit back feed. Can.

  Further, the editing apparatus 1 sets one rotation of the micro movement jog 15 as an operation amount for one frame number, thereby forming an angle of 1 / multiplication with respect to one rotation for a high frame rate obtained by multiplying the reference frame rate. Can be regarded as the amount of operation for one subframe. As a result, the editing operator can intuitively easily grasp the return amount or the feed amount to each subframe during the reference frame (for example, the Odd subframe).

  Further, the editing apparatus 1 enables the video operation by the button operation separately from the jog dial by providing the minute return button 16-1 or the minute feed button 16-2, and the convenience according to the situation of the editing operator. It can improve.

  In addition, the editing apparatus 1 switches the role of each operation unit (jog dial and button) for micro movement or low speed movement to any one of the states 1, 2 or 3 by providing the switching button 17 in the operation controller 10. Can. Therefore, the editing apparatus 1 can appropriately change the operability according to the frame rate of the video material to be edited or the situation of the editing operator, and the convenience is improved.
