The present invention relates to an apparatus and method for deleting and editing an image signal recorded on a recording medium, and more particularly, to an apparatus and method for conveniently deleting and editing an image signal photographed by a camcorder. It is about.

Conventionally, a method of deleting and editing unnecessary portions of an image screen photographed by a camcorder has been a manual method, which has been cumbersome in searching for an erasing section, deleting a selected section, and rewriting a deleted section.

It demonstrates with reference to FIG. Suppose that the interval to be deleted has a figure and '1', '2', and '3' details. There are two conventional methods of deleting unnecessary parts. If you want to delete the 'Delete section-1', one thing, the user checks the counter value (0004 ~ 0010) of the section to be deleted while watching the playback screen in advance, rewinds it, and then plays the screen at the counter value '0004'. Pressing the delete key and reselling the key at the counter value '0010' completes the deletion. Another is to store the counter value (0010) in the storage unit when the playback screen reaches the end of the delete section. After rewinding the screen and pressing the delete key at the counter value '0004' while the screen is playing, the deletion starts. When the counter value reaches '0010', the comparison with the counter value stored in the memory means coincides with the deletion. That's how it works.

In addition, the operation of recording the necessary video signal in the previously deleted portion also required the user to directly check whether the deleted portion was visible while searching or replaying the recording medium, and then recording the necessary screen.

In the conventional method, the delete operation is intermittently performed, and if there are more parts to delete, the confusion and troublesomeness of the search operation is increased and the work speed is slowed down. There is discomfort that must be preceded.

Therefore, in order to improve the conventional method, the video signal deleting and editing method and the method of controlling the recording can be continuously deleted by using the counter value of the section to be deleted, and the method of the method. The purpose is to provide a device for implementation.

To this end, the apparatus of the present invention comprises a deletion section selection means for generating a deletion section setting signal, a continuous deletion start means for generating a deletion execution signal, automatic / manual recording selection means for generating an automatic or manual recording selection signal, The microcomputer stores information on the erasing section and controls deletion and recording according to the signals input by the three means, and color signals inside the video recording apparatus or external camera signals are selected according to the automatic / manual recording control signals of the microcomputer. Characterized in that the recording signal selection means.

In addition, the method of the present invention, the deletion section selection process of selecting the section to be deleted to be stored in the storage device, the continuous deletion process of deleting while searching for the section selected in the deletion section selection process and the image recording according to automatic or manual selection It includes automatic / manual recording process that can selectively record constant signal generated inside the device or camera signal from outside.

Hereinafter, with reference to the accompanying drawings will be described in detail.

2 shows at least the means necessary for the practice of the invention.

Deletion section selection means comprises a deletion start display means 10 for displaying the start position of the section to be deleted and the deletion end display means 12 for displaying the end position, which is triggered by 'ON' at both ends of the section to be deleted. By applying the signal to the microcomputer, the position information of the erasing section is stored in the RAM 28 of the microcomputer 18. Here, the position corresponding to the position of the section to be deleted becomes a counter value at the corresponding position, and thus the information stored in the RAM is a counter value, and the information of the deletion start point and the information of the deletion end point are separated by separate color lines in the RAM. And stored.

The continuous deletion initiation means 14 turns on when the continuous deletion operation is to be executed, thereby allowing the microcomputer to control the deletion operation.

The automatic / manual recording selection means 16 is used to record desired video data in a previously deleted section, and the selected mode signal is input to the microcomputer. In the microcomputer, when the selection signal is 'auto', the blue, red, ... generated inside the On Screen Display IC from the recording signal selection means 30. The control signal is outputted so that a constant color signal such as is selected. In the case of 'manual', the control signal is outputted so that an external video signal photographed by the camera is selected.

The erasing section selecting means 10, 12, the continuous erasing start means 14, and the automatic / manual recording selecting means 16 can turn the contact on or off, so that either the mechanical contact or the electronic contact can be used. Do.

The method of the present invention, as shown in FIG. 3, consists of an erasing section setting process 42, a continuous erasing process 44, and an automatic / manual recording process 46, each provided as long as power is supplied to the microcomputer. The process runs sequentially and goes through an infinite loop.

4 is a flowchart more specifically illustrating the deletion section selection process 42. This process includes determining whether the user wants to set a deletion section (step S2) and storing a counter value of the section to be deleted in the RAM by the input signal of the deletion section setting means (10, 12) (steps S4 to S10). Are divided into

First, since the selection of the section to be deleted is made while the user watches the playback screen, it is first determined whether the playback mode is in the step S2. If it is not in the playback mode, it means that the deletion section selection operation is not performed, so the step of selecting the deletion section is exited, and in the playback mode, the position information of both ends of the section to be deleted can be stored in the RAM (steps S4 to S10). Enter

To save the deletion section, first, when the user turns on the deletion start display means 10, the counter value at that time is recorded in a section for storing information on the RAM start deletion point (steps S4 and S6). When the display means 12 is turned ON, the counter value at that time is similarly recorded in the section for storing information on the end point of erasing the RAM (steps S8 and S10). If neither of the deletion start display means or the deletion end display means is turned on in the regeneration mode, no information is stored in the RAM since the step of storing the counter value in the RAM (steps S6 and S10) is not performed.

This completes the setting process of the delete section. When the setting of the erasing section is completed, the user can rewind the tape and prepare for the subsequent continuous erasing operation according to the first counter of the erasing section.

5 is a flowchart embodying the continuous delete process 44. This process includes the steps of judging whether or not to delete (steps S20 to S26), actually executing steps (steps S28 to S38), and confirming the completion of the delete operation to execute the next automatic / manual recording process 44. It is comprised of the steps (S40-S48 step) which are made to make this possible.

In this process, first, it is determined whether or not the delete mode is 'set' (step S20), but since the delete mode is 'non-delete' mode (step S26), the continuous deletion start means 14 is always performed. The process branches to the step of checking whether the data is 'ON' (step S22). Here, if the user has turned on the continuous deletion initiation means 14 to execute the continuous deletion, the process branches to a step (step S24) of checking whether or not the information stored in the deletion RAM exists. If there is information to be deleted in the RAM in step 'S24', the delete mode is 'set' (step S24), and if not, the delete operation is not required, thereby exiting the continuous deleting process 44.

If the delete mode is in the 'set' state, the delete mode check step (step S20) at the next loop execution is always 'yes', and thus branches to the actual delete execution step (steps S28 to S38). The start of deletion (step S30) searches and compares the current counter value and the counter values stored in the RAM start section (step S28) and starts deletion at the tape position corresponding to the matched counter value. The end of the deletion (steps S32 and S34) is also performed in the same manner as the deletion start (steps S28 to S30), except that the deletion mode is 'reset' after the deletion of each deletion section is finished (step S34). S36) is added. On the other hand, in the non-erasing section, the erasing operation is promptly performed by setting the running speed of the tape to the high speed mode (FF) (step S38).

When all the continuous erasing operations are completed and no further erasing operation is necessary, the operation of rewinding and positioning the tape at the first erasing start position (steps S40 to S46) is performed. In addition, when all the deletions are completed, the deletion completion flag 'set' is set to indicate completion (step S48).

6 shows a flow chart of the automatic / manual recording process. This process is for recording a color signal generated inside the video recording apparatus or an external video signal photographed by a camera in the deleted section (replaying this section results in a screen state without image information). Checking whether or not it is completed (steps S60 to S62), searching for and deleting previously deleted sections (steps S64 to S74), and confirming completion of the recording operation to initialize all states (steps S76 to S80). Is done.

Specifically, first, check whether the deletion is completed (step S60) and whether there is a deleted part (step S62), and then search and compare the current counter value and the counter values stored in the RAM deletion start section. (S64 step), the mode selection state of the automatic / manual recording selection means 16 is judged when the two match (step S66).

If the user selects 'Auto', the blue, red, ... A predetermined color signal is selected (step S70), and when the manual mode is selected, an image signal directly input from the outside by the camera is selected (step S68) and recorded in the deleted section. Here, the selection of the 'automatic' recording is to process the deleted section in a more convenient way by automatically recording a predetermined color signal in the deleted section. Thereafter, after confirming that the tape has proceeded to the end point of the erasing section (step S72), the recording operation of the section is finished (step S74).

Next, the completion of the recording operation for all deletion sections is checked for each loop (step S76). Upon completion, all values of the RAM are cleared (step S78), and the reset flag is 'reset'. (Step S78), incomplete, exits the loop for recording the next deletion section. In this way, editing is completed by continuously searching for deleted sections and selectively recording signals.

The three processes, that is, the deletion section setting process 42, the continuous deletion process 44, and the automatic / manual recording process 46, are sequentially executed as described above and run in an infinite loop.

As described above, the present invention has the effect of not only processing the operation more easily when deleting or recording a video signal, but also reducing the working time.
