Next, an outline of an embodiment according to the present invention will be described first. This embodiment has the following features.
1. Operation buttons for entering the refinement control mode in addition to the operation buttons such as playback / pause / fast forward / rewind / frame (frame) advance / frame (frame) rewind / decision / cancel, which are normally used when editing movies Is provided.
2. A step size for narrowing-down control (initial value of the number of frames (number of frames) sent or returned by one frame advance / frame return) is set.
3. A mode for specifying a frame near the desired frame to be searched (squeezed control mode) is entered.
4). After entering the narrowing-down control mode, a pause state is entered, and frame advance / return operations are performed in units of step sizes.
5. Every time the frame movement operation is performed after switching to the narrowing control mode, the direction of frame advance (frame return) is switched first (ie, frame advance to frame return or frame return to frame advance). Control to halve the step size (step size halving control) is performed. This is because it is determined that a desired frame has been passed (stradded) when the direction of frame advance (frame return) is first switched.
6). Thereafter, the operation is continued in the direction approaching the desired frame, and when the desired frame cannot be found on the way and the step size finally becomes 1 frame, the narrowing down to the desired frame or the frames before and after that is completed. Therefore, the desired frame can be specified (the minimum step size is 1 frame).
7. Since the desired frame has been specified in 6 above, the “OK” button is pressed to finish the editing operation.

  FIG. 4 is a diagram for explaining the outline of the operation according to the embodiment of the present invention.

  Here, an editing operation for deleting commercials (hereinafter referred to as CM) between programs will be described as an example. In FIG. 4, reference numeral 41 denotes video content, which flows from the left to the right (from program A to program B) in the normal viewing state.

  First, as shown in FIG. 4, assuming that there are a plurality of CMs between program A and program B, these CMs are designated as CMA, CMB, CMC, and CMD. Here, it is considered that CMA, CMB, CMC, and CMD between program A and program B are deleted.

  The video signal is reproduced at a rate of 30 frames / second. The CMA, CMB, CMC, and CMD are assumed to be played back for 15 seconds each, and each has 450 frames.

  In addition, it is assumed that the initial step size when the step size halving control is performed is set in advance before starting the narrowing down control mode in the moving image editing according to the present embodiment.

  FIG. 5 shows a schematic flow of moving image editing.

  In order to perform video editing (here, an example of CM deletion is described, but the present invention is not limited to this, and can be used for frame specification at the time of frame movement editing, etc.), a deletion start point frame and a deletion end point frame are extracted There is a need to. Step C1 in FIG. 5 shows a routine for extracting a deletion start point frame, and step C2 shows a routine for extracting a deletion end point frame. The deletion start point frame or the deletion end point frame is a narrowing control according to the present embodiment. Since each mode can be extracted in the same manner, the description here is for the case where the deletion start point frame has already been extracted in step C1, and then the deletion end point frame is extracted in step C2. explain.

  In this case, it is assumed that the deletion start point frame is the first frame of CMA started after program A, and this frame has been extracted. The deletion end point frame is assumed to be the last frame of the CMD before the program B, and this frame is the target frame for the end of deletion. When the deletion start point frame and the deletion end point frame are extracted, the frames from the deletion start point frame to the deletion end point frame are deleted in step C3, and the moving image editing ends.

  When the description is continued with reference to FIG. 4, first, in order to start the narrowing control mode, any frame of CMA, CMB, CMC, and CMD between the deletion start point frame and the deletion end point frame is narrowed down. Set to the start frame of. In the example of FIG. 4, it is assumed that an arbitrary frame of the CMB is set as the start frame of the narrowing down control mode.

  As shown in FIG. 4, the moving image editing of the present embodiment set as described above is performed as follows: the first frame of the CMA is the editing start frame, the last frame of the CMD is the editing end target frame, and an arbitrary frame in the middle of the CMB Is the point at the start of the refinement control mode.

  The operation in the narrowing-down control mode proceeds as follows.

Step A1;
When the narrow-down control mode is started using an arbitrary frame in the middle of the CMB as a point at the start of the narrow-down control mode, the video is temporarily stopped.

Step A2;
Since the CMB is in progress, the “frame advance” button is pressed, and the process advances 450 frames. These 450 frames are step sizes set in advance before the start of the narrowing-down control mode.

Step A3;
Since the destination advanced by the operation of step A2 is CMC, the “frame advance” button is further pressed to advance 450 frames ahead.

Step A4;
Since the destination advanced by the operation of step A3 is CMD, the “frame advance” button is further pressed to advance 450 frames ahead.

Step A5;
Since the destination advanced by the operation of step A4 is the program B, the “return frame” button is pressed, and the process returns to 256 frames later. Step size halving control is started from the point in time when the “frame return” button is pressed.

The step size in this step size halving control is determined as follows (b) (b).
(B) The first step size in step size halving control is
Step size setting value / 2 ≦ 2 ⁿ <Step size setting value (Equation 1)
The value of ²ⁿ satisfying However, n is 0 or a positive integer. Therefore, in this case, since the step size setting value = 450 frames, 2 ⁿ = 256 frames is determined.
(B) For the second and subsequent step sizes in the step size halving control, the previous step is halved (1/2 times).

As described in (a) above, considering that the step size is successively halved in the step size halving control, it is more convenient to make it 2 ⁿ , that is, a multiple of 2.

  The step size half control will be described with reference to FIG. 6 which is an enlarged view of FIG.

  FIG. 6 shows operations from step A6 to step A13 following step A5 in the step size halving control of FIG.

Step A6;
Since the return destination in the operation of step A5 is the program B, the “frame return” button is further pressed, and the process returns to 256 frames / 2 = 128 frames later.

Step A7;
Since the destination returned by the operation in step A6 is CMD, the “frame advance” button is pressed, and the process advances to 128 frames / 2 = 64 frames ahead.

Step A8;
Since the destination advanced by the operation of step A7 is CMD, the “frame advance” button is further pressed to advance 64 frames / 2 = 32 frames ahead.

Step A9;
Since the destination advanced by the operation of step A8 is CMD, the “frame advance” button is further pressed, and the processing advances to 32 frames / 2 = 16 frames ahead.

Step A10;
Since the destination advanced by the operation of step A9 is CMD, the “frame advance” button is further pressed, and the processing advances to 16 frames / 2 = 8 frames ahead.

Step A11;
Since the destination advanced by the operation of step A10 is the program B, the “return frame” button is pressed, and the process returns to 8 frames / 2 = 4 frames later.

Step A12;
Since the destination returned by the operation of step A11 is the program B, the “return frame” button is further pressed to return after 4 frames / 2 = 2 frames.

Step A13;
Since the return destination in the operation of step A12 is the program B, the “frame return” button is further pressed, and the process returns after 2 frames / 2 = 1 frame. The destination after one frame is CMD.
Since the destination returned by the operation of step A13 is CMD and the step size is changed from program B to CMD in one frame in this way, it is determined that the target frame has been reached.

Step A14;
Press the “OK” button to specify the target frame for editing and exit the narrowing down control mode.

  Furthermore, the operation of the step size half control in the present embodiment will be described with reference to FIGS. 7 and 8 as another example. The example described above with reference to FIGS. 4 and 6 is an example in which the desired frame is a frame that has been moved after the step size becomes 1 frame in the step size half control. This is an example in which the frame moved after the step size becomes one frame is adjacent to the desired frame. FIG. 7 has already entered step size halving control, step B1 is step size = 16, step B2 is step size = 8, step B3 is step size = 4, step B4 is step size = 2, and step B5 is step. The case where size = 1 and step B6 becomes step size = 1 is shown.

Step B1;
Since the movement source in step B1 is during CMD (see FIG. 8A), the “frame advance” button is pressed and the process proceeds to 16 frames ahead.

Step B2;
Since the destination advanced by the operation of step B1 is program B (see FIG. 8B), the “return frame” button is pressed, and the process returns to 16 frames / 2 = 8 frames later.

Step B3;
Since the destination returned by the operation of step B2 is the program B (see FIG. 8C), the “return frame” button is further pressed, and the process returns after 8 frames / 2 = 4 frames.

Step B4;
Since the destination returned by the operation of step B3 is CMD (see FIG. 8D), the “frame advance” button is pressed, and 4 frames / 2 = 2 frames ahead.

Step B5;
Since the destination advanced by the operation of step B4 is the program B (see FIG. 8E), the “return frame” button is pressed, and the process returns by 2 frames / 2 = 1 frame.

Step B6;
Since the destination advanced by the operation of step B5 is the program B (see FIG. 8F), the “return frame” button is further pressed. At this time, the calculated value of the step size according to Equation 1 does not become smaller than 1 and returns by one frame. The screen at this time is as shown in FIG. 8G, but this screen is the same as FIG. 8D.

  As in this example, when the destination moved with step size = 2 switches from program to CM or from CM to program, the next step size becomes 1 frame by step size halving control. In the first step or the second step, the program is surely switched to the CM or from the CM to the program (returning to the original frame when moving with the step size = 2 always goes back twice when the step size = 1). . In other words, when the screen is in the CM, the narrow-down control mode is entered. If the screen is in the middle of the program, the “frame advance” operation is performed. If the screen is in the middle of the program, the “frame return” operation is performed. Considering the situation of selection, the destination moved after the current step size becomes 1 is the desired frame, or the adjacent frame across the boundary between the CM and the program. In the case of the adjacent area, “frame return” or “frame advance” of step size 1 is performed once again to obtain a desired frame (the step size is not reduced after 1).

<Other screen display examples>
In the above example, the desired frame has actually been reached at the time after the operation of step B3, but this cannot be determined by editing on a single screen. Therefore, if the editing screen is such that the screen one frame ahead as shown in FIG. 9 is also displayed side by side, it can be seen that the frame is the desired frame even during the narrowing operation. That is, when the two screens on the left and right display a program and a CM at the same time, the CM screen displayed at this time is the editing end target frame. In this case, editing can be completed with fewer steps than editing on a single screen.

  Next, the operation of the present embodiment will be described with reference to the flowchart of FIG. A program to be executed in accordance with this flowchart is stored in the storage means ROM 13 provided in the moving picture recording / editing apparatus 1 and executed by a microcomputer including the CPU 30 provided in the moving picture recording / editing apparatus 1. During editing, one frame of the moving image is designated and displayed on the monitor device 3 as a still image. The user confirms the content of the video displayed on the monitor device 3, operates the “frame advance” button 23, “frame return” button 24, “cancel” button 22, etc., finds the desired frame, and traces to the desired frame. When it arrives, the “determine” button 21 is pressed to register a desired frame, and the editing operation is completed.

First, initial conditions for starting the narrowing-down control mode are set (step S1).
(1) SS (Step Sise) setting value: 450F (this value can be arbitrarily changed by the user)
(2) SS (Step Sise) present value: Initial value is the same as SS set value (3) Control state: 0

Here, “(3) Control state” is 0: Reset state,
1: SS feed (control to send a frame with the step size being the initial step size),
2: SS return (control to return the frame with the step size being the initial step size),
3: Narrowing control (control to send or return frame while halving the step size),
Can be set.
The “(1) SS (Step Sise) set value” is not set when the narrowing control mode is started, but is set in advance before the start, and can be changed at any time, and when the narrowing control mode is started. It can be changed if necessary.

  Next, it is determined whether or not the “narrowing control mode” button has been pressed (step S2).

  If it is determined in step S2 that the “narrowing control mode” button has been pressed (Yes in step S2), the process returns to step S1 to reset initial conditions. Since it is assumed that the narrowing-down control mode is redone, the initial condition is reset.

  If it is determined in step S2 that the “narrowing control mode” button has not been pressed (No in step S2), the process proceeds to step 3 to determine whether the “frame advance” button has been pressed.

  If it is determined in step S3 that the “frame advance” button has not been pressed (No in step S3), the process proceeds to step S4 to determine whether the “frame return” button has been pressed.

  If it is determined in step S4 that the “return frame” button has not been pressed (No in step S4), the process proceeds to step S5 to determine whether the “decision” button has been pressed.

  If it is determined in step S5 that the “OK” button has not been pressed (No in step S5), the process proceeds to step S6 to determine whether or not the “Cancel” button has been pressed.

  If it is determined in step S6 that the “Cancel” button has not been pressed (No in step S6), the process returns to step S2 and the processes in and after step S2 are continued.

  If it is determined in step S5 that the “OK” button has been pressed (Yes in step S5), the process proceeds to step S8, where the currently displayed frame is processed as a desired frame, and then the process proceeds to step S7.

  If it is determined in step S6 that the “Cancel” button has been pressed (Yes in step S6), the process proceeds to step S7.

  In step S7, a process for exiting the narrowing-down control mode is performed, and this narrowing-down control mode is terminated.

  If it is determined in step S3 that the “frame advance” button has been pressed (Yes in step S3), the process proceeds to step S9 to check whether the control state is 3 or not.

  If it is determined in step S9 that the control state is 3 (squeezed control) (Yes in step S9), the process proceeds to step S10, and frames for the SS current value are transmitted. After sending the frame by the SS current value, SS current value ÷ 2 is obtained and set as a new SS current value.

  Next, proceeding to step S11, it is checked whether or not the value calculated as SS current value / 2 is smaller than 1 in order to halve the SS current value at step S10.

  If it is determined in step S11 that the SS current value has become smaller than 1 (Yes in step S11), the SS current value is set to 1 (step S12), and the process returns to step S2.

  If it is determined in step S11 that the SS current value is greater than 1 (No in step S11), the process returns to step S2.

  If it is determined in step 9 that the control state is not 3 (narrowing control) (No in step S9), the process proceeds to step S13, and it is checked whether the control state is 1 (SS sending state).

  If it is determined in step S13 that the control state is 1 (SS sending state) (Yes in step S13), the process proceeds to step S14 to send frames for the SS current value, and then returns to step S2.

  If it is determined in step 13 that the control state is not 1 (SS feed state) (No in step S13), the process proceeds to step S15 to check whether the control state is 0 (reset state).

  If it is determined in step S15 that the control state is 0 (reset state) (Yes in step S15), the process proceeds to step S16 to send the SS current value frame and set the control state set value to 1 (SS send). Then, the process returns to step S2.

If it is determined in step S15 that the control state is not 0 (reset state) (No in step S15), the process proceeds to step S17, the control state is set to 3 (squeezing control), and ²ⁿ in the above equation 1 is satisfied. A value is obtained as an SS current value, and frames are transmitted by the obtained SS current value. After sending the frame by the SS current value, SS current value ÷ 2 is obtained and set as a new SS current value. Next, the process proceeds to step S11 described above, and the subsequent processing is executed.

  If it is determined in step S4 that the “return frame” button has been pressed (Yes in step S4), the process proceeds to step S18 to check whether the control state is 3 or not.

  If it is determined in step S18 that the control state is 3 (squeeze control) (Yes in step S18), the process proceeds to step S19, and frames for the SS current value are returned. After returning the frame by the SS current value, SS current value ÷ 2 is obtained and set as a new SS current value.

  Next, the process proceeds to step S20, and it is checked whether or not the value calculated as SS current value / 2 is smaller than 1 in order to halve the SS current value in step S19.

  If it is determined in step S20 that the SS current value is smaller than 1 (Yes in step S20), the SS current value is set to 1 (step S21), and the process returns to step S2.

  If it is determined in step S20 that the SS current value is greater than 1 (No in step S20), the process returns to step S2.

  If it is determined in step S18 that the control state is not 3 (squeezed control) (No in step S18), the process proceeds to step S22, and it is checked whether the control state is 2 (SS return state).

  If it is determined in step S22 that the control state is 2 (SS return state) (Yes in step S22), the process proceeds to step S23 to return frames for the SS current value, and then returns to step S2.

  If it is determined in step S22 that the control state is not 2 (SS return state) (No in step S22), the process proceeds to step S24 to check whether the control state is 0 (reset state).

  If it is determined in step S24 that the control state is 0 (reset state) (Yes in step S24), the process proceeds to step S25 to return the SS current value frame and set the control state set value to 2 (SS return). Then, the process returns to step S2.

If it is determined in step S24 that the control state is not 0 (reset state) (No in step S24), the process proceeds to step S26, the control state is set to 3 (squeezing control), and ²ⁿ in Equation 1 is satisfied. The value is obtained as an SS current value, and frames are returned by the obtained SS current value. After returning the frame by the SS current value, SS current value ÷ 2 is obtained and set as a new SS current value. Next, the process proceeds to step S20 described above, and the subsequent processing is executed.

  By the way, with the MPEG video compression technology, a video composed of a plurality of frames is created by predicting in one direction the movement of a frame that is temporally after the reference I picture and the reference I picture. A P picture, a B picture created by predicting motion in both directions from the preceding and following P pictures or the I picture. Therefore, when the present invention is applied to editing of a moving image using MPEG moving image compression technology, it is conceivable that only an I picture is a search target. In this way, it is not necessary to perform an operation for restoring the P picture and B picture using the difference data, and a desired frame can be extracted at high speed.

  When the desired I picture, for example, the I picture frame of the CM immediately before the program is extracted using only the I picture, the next I picture in time becomes the I picture of the program. The P picture or B picture can be left without being deleted, or can be deleted. When changing from CM to a program, the scene changes greatly between the desired I picture and the next I picture, so there may be no P picture or B picture between them. In the case of a continuous scene that does not change abruptly, even if a frame exists here, even if there is a frame, it is a short time (for example, 30 frames / second and I picture is every 15 frames, 0 .5 seconds), there is no practical problem even if the deletion process is not performed.

  As described above, the present invention has been described in the specific embodiment. However, according to the above embodiment, the edit screen displayed on the monitor device can be operated on a single screen, and there is an effect that a desired frame can be searched more quickly than before. . Further, if the editing screen of the monitor device is set to a two-screen display that displays two consecutive frames, a desired frame can be further quickly searched.

  Further, in the prior art, it is necessary to display a plurality of frames of a moving image to be edited on the screen for video processing, and a large memory capacity is required. However, according to the present embodiment, a single screen is used. Since it can be operated and has two screens at most, there is an effect that a memory capacity required for video processing can be reduced. Further, since the screen to be processed is a single screen and at most two screens, it is not necessary to request the CPU for high-speed processing capability. Therefore, it is advantageous for reducing the size of the moving image editing apparatus, and the price can be reduced.

  Moreover, it goes without saying that the present invention is not limited to the above-described embodiment, and can be modified without departing from the spirit of the present invention. For example, the present invention can also be applied to a case where a program is recorded on a hard disk built in the television receiver and edited using the television receiver. In this case, the program for carrying out the present invention is stored in the storage device of the television receiver, and the display device of the television receiver itself can be used as the monitor device. When the present invention is applied to a video camera, the video recording / editing device 1 can use the video camera itself, the monitor device 3 can use the display device of the video camera, and the remote control device 2 can be operated with operation buttons provided on the video camera body. can do. In this case, a program for carrying out the present invention is stored in the storage device of the video camera.

  The present invention can be widely used for image editing of a video recording apparatus.
