In the case of this embodiment, for example, in the case of a cassette tape, a constituent memory of an EEPROM attached to a case compresses a predetermined timing image on a magnetic tape and stores an image index generated together with the additional information.

Accordingly, in the case of the video tape recorder 1, when the user operates the operation buttons for the search processing, for example, the global button 4, the view button 5, and the local button 6 during playback, A global search screen, a view search screen, and a local search screen are displayed, respectively, and the user operates the roller 7 to execute the corresponding search processing. When the user operates the display button 9 after the search, the magnetic tape is processed to be squeezed or rewound up to the searched position, and playback is performed from the searched position.

The video tape recorder 1 is configured as shown in Fig. The operation inputs of the global button 4, the view button 5, the local button 6, the display button 9, the pause button 10 and the stop button 11 are read out from the key reading circuit 20 , And is once stored in the key input memory 21. The contents of the key input stored in the key input memory 21 are sequentially read by the search control circuit 22 including the central processing unit (CPU). The search control circuit 22 executes search processing in accordance with the key input.

The rotation amount by the operation of the roller 7 is inputted to the search control circuit 22 and the display screen creation circuit 25 through the roller cursor position memory 24 retrieved by the rotation detection circuit 23. [ The search control circuit 22 has a state memory 26 for recording a processing state and stores a target playback position and a current playback position for the purpose of searching through the target playback position memory 27 and the playback position memory 28, And inputs it to the display screen creating circuit 25.

[

(2) Processing of image index

Here, in the video tape recorder 1 of this embodiment, a system control circuit (not shown) that controls the entirety including the CPU executes the entire processing program SP0 as shown in FIGS. 3 and 4 Thereby performing recording and reproduction processing using an image index. That is, the CPU of the system control circuit is inputted from the entire processing program SP0, and it is judged whether or not the cassette tape is inputted in the system SP1, and when the cassette tape is not inputted, it is regarded that the cassette tape is loaded.

Subsequently, the CPU reads the image index from the memory arranged in the case of the cassette tape at the next step SP2, and judges whether or not the image index read at the step SP3 is normal. If it is normal, the CPU executes the step SP4 The internal flag FLAG is set to TRUE and the routine moves to the next step SP5. If the flag FLAG is not normal, the step SP6 is executed to set the flag FLAG to FALSE And goes to step SP5.

In this step SP5, the CPU judges whether or not the cassette tape is contained. If the CPU obtains a negative result here, it returns to the above-mentioned step SP1 and regards the cassette as being carried.

If an affirmative result is obtained here, the process proceeds to the next step SP7 to determine whether the video tape recorder 1 is recording or not. If YES in step SP8, the process proceeds to step SP8, , The flag FLAG is set to [TRUE] and the process goes to step SP10. If a negative result is obtained in step SP7, the process directly proceeds to step SP10.

The CPU determines whether or not an image index (VID) generation button (not shown) is pressed in this step SP10. If the CPU 11 obtains an affirmative result, the CPU goes to step SP11, , The flag FLAG is set to [TURE] and the process goes to step SP13. If a negative result is obtained at step SP10, the process goes to step SP13.

At this step SP13, it is determined which one of the global button 4, the view button 5 and the local button 6 has been pressed as a search button using the image index. If an affirmative result is obtained, the process goes to step SP14, (FLAG) is [TRUE], that is, whether or not the image index is correctly read or correctly generated. If an affirmative result is obtained in this step SP14, the CPU executes the search process corresponding to the operation button in the next step SP15 and goes to the step SP16.

When the CPU obtains a negative result at step SP13 and step SP14, the CPU immediately goes to step SP16. At step SP16, it is judged whether or not the stop button 11 indicating completion is operated, If it is obtained, the entire processing program SP0 is terminated in the next step SP17, and if the result is negative, the procedure goes to the above-mentioned step SP5.

Then, the CPU executes the subroutine in the image index data reading processing procedure RT (2) in FIG. 5 as the image index read processing described above in step SP2. The CPU enters from the image index data reading processing procedure RT (2) when the image index is read by the memory attached to the case of the cassette tape, and the number of the tape ID, the total tape amount and the image index in the next step (SP21 to SP23) Read into memory.

Subsequently, the CPU reads the timer code and the corresponding image index into the internal memory at steps SP24 and SP25, determines whether the number of image indexes is repeated by the number of image indexes in the next step SP26, and obtains a negative result, (SP24) and (SP25). If an affirmative result is obtained, the process goes to step SP27 to complete the image index data reading processing procedure RT (2).

The CPU executes the subroutine of the image index data generation processing procedure RT (8) shown in FIG. 6 as the image index generation processing described above in steps SP8 and SP11. The CPU enters the image index data generation processing procedure RT 8 and calculates and stores the tape ID at steps SP31 and SP32. At the same time, the CPU irradiates and stores the total tape amount based on the rotation period or the like, The counter 7 is initialized to zero.

Subsequently, in step SP34, the CPU resets the timer 29 for displaying the image index at all the retrieval time intervals, determines whether the stop button 11 is pressed or tape-ended in the next step SP35, If a negative result is obtained, the process goes to the next step SP36 to determine whether the timer 29 has elapsed 15 seconds, and if the result is negative, the process goes to the above-mentioned step SP35.

If the CPU obtains an affirmative result in step SP36 after lapse of 15 seconds by the timer 29, the next step SP37 is executed to analog-digitally convert the image signal of the video screen shown in Fig. 7a to the frame butter I remember. At this time, as shown in FIG. 7B, each pixel of 640 pixels x 480 lines is represented by one pixel 24 (bits), and the amount of data is about 922 (kilobytes) as one screen.

Subsequently, the CPU executes the steps SP38 and SP39 to compress the data of one pixel of 24 bits into 5 bits and reproduces data of one screen of 640 pixels x 480 lines into 64 pixels x 48 And the resolution is reduced to 1/10 and the amount of data is 1.92 (kilobytes) as shown in FIG.

Subsequently, the CPU performs the next step SP40 to compress the data amount of about 1.92 (kilobyte) to 1/2 by using the langence coding technique, and to compress the data amount of 0.96 (kilobytes) A cell of an image index which is a data amount is created.

The CPU executes the steps SP41 and SP42 to read the timer code corresponding to the cell of the image index created as described above, and sequentially sets the timer code and the cell as the image index In the memory.

Actually, when the total length of the magnetic tape is 120 minutes and the image index is created at intervals of 15 seconds as described above, the data amount is 463 (kilobytes) as shown in the following expression (1).

[Formula 1]

964 [byte] x (120 x 60) / 15 = 463 [kbyte] (1)

Then, at the next step SP43, the CPU counts up the counter n and goes to the above-mentioned step SP34 to create an image index for the next screen.

If the CPU 11 obtains an affirmative result at step SP35, the CPU goes to step SP44 to determine whether the stop button 11 has been pressed or the tape end, and stores the value of the counter n as the number of image indexes, SP45) ends the image index data generation processing procedure RT (8).

The image index in the actual memory is stored in accordance with the memory map shown in Fig. The tape ID is stored at 4 bytes from the head of the memory, the total tape amount is stored at 4 bytes continuously, the number of image indexes is stored at 2 bytes, and the time code for displaying the position on the magnetic tape and the image index And 960 bytes, and only the portion of the image index is stored. Thus, the image index is generated.

(3) View search processing

The CPU of the search control circuit 22 and the display screen creation circuit 25 of the video tape recorder 1 of this embodiment performs the search processing of the steps SP13 to SP15 over the entire processing program SP0 using the image index ID , The view button 5 is pressed and the view search processing program SP50 shown in FIG. 9 and FIG. 10 is executed.

Here, as shown in FIG. 11, the view search processing circuit arranges and displays a predetermined number of image indexes IDX in the form of a matrix on the display screen DSP in accordance with the time series, centering on the reproduction position on the magnetic tape on which the magnetic head is currently in contact, , And a search process for causing the cursor CS to designate the target playback position.

At this time, each cell image of the image index IDX follows the order of the corresponding timer codes while going downward from the upper left direction to the right direction.

A mark MK indicating the reproduction position on the display screen DSP and a cursor CS indicating the target reproduction position representing the animation as a moving person, for example.

When the cursor CS reaches the left end of the display screen DSP, the cursor CS is moved upward. When the cursor CS reaches the right end, the cursor CS is moved downward. When the cursor CS reaches the upper left of the display screen DSP, the entire image index IDX in the display screen DSP scrolls upward by one row, and conversely scrolls downward by one row in the rightmost edge.

The CPU of the actual image search control circuit 22 and the display screen creation circuit 25 enters from the view search processing program SP50 and determines whether or not the view button 5 is pressed in the next step SP51 and obtains an affirmative result The flow advances to the next step SP52 to judge whether or not the search screen ends the display. In the first process, a negative result is obtained, and the CPU goes to step SP53.

In this step SP53, the CPU switches to the search screen, which is the display screen DSP for the view search described above, on the display screen 11 of the reproduction screen displayed on the color liquid crystal display 2, and at the next step (SP54) The current playback position is set in the memory 27. [

Subsequently, the CPU reads the stop cast shown in FIG. 12E or FIG. 12F from the animation icon memory 32 and displays it as a cursor CS. Next, the CPU next executes the step SP56 to set the animation of the still image in the animation mode memory 31 in the stopped state.

Next, based on the contents of the target image position memory 27 in step SP57, the CPU reads the image index IDX in the vicinity of the target playback position from the target playback position screen memory 33 and displays it on the display screen DSP in accordance with the time series And the marker MK is displayed at the position corresponding to the reproduction position in the subsequent step SP58, and the process goes to step SP59.

The CPU determines whether or not the display button 9 is pressed in this step SP59.

When the view button 5 is normally pressed, the display button 9 is pressed during the view searching process, which means that the searching process is completed and the tapping of the magnetic tape is actually executed. In the ordinary searching process, The process goes to step SP60.

In this step SP60, it is determined whether or not the roller 7 is moved based on the rotation information of the roller 7 entered from the roller cursor position memory 24. If a negative result is obtained, the CPU proceeds to the next step SP61 The timer 29 is reset to perform the display switching of the casting even in the state where the rollers do not move, and the process goes to the next step SP62.

At this step SP62, the CPU judges whether or not the position of the cursor CS is on the upper left on the display screen DSP. If the CPU obtains a negative result at this step SP62, the CPU executes the next step SP63 to determine the position of the cursor CS on the left- If the result is negative, the CPU proceeds to the next step SP64.

If the CPU obtains an affirmative result at the above-mentioned step SP62, the process goes to step SP65 and scrolls the display area downward and then goes to step SP64. If the CPU obtains an affirmative result at step SP63, the CPU goes to step SP66 The display area is scrolled up, and the process goes to step SP64.

In this step SP64, the cursor CS is moved to the target playback position and it is determined whether or not the roller 7 has moved to the right in the next step SP67. Here, if an affirmative result is obtained, the CPU goes to step SP68 and refers to the animation mode memory 31 to determine whether the current animation mode is the right animation mode.

Here, if an affirmative result is obtained, the CPU goes to step SP69 and goes to step SP51 after changing the right cast (indicated by the cursor CS in FIG. 12C or 12D).

If the CPU obtains a negative result at step SP68, the CPU goes to step SP70 and displays the cast in the cast mode (step 12c or step 12d, as well as the animation mode memory 31) After setting the animation mode, the flow goes to step SP51.

If a negative result is obtained at step SP67, the CPU goes to step SP72 and refers to the animation mode memory 31 to determine whether the current animation mode is the left animation mode.

If an affirmative result is obtained here, the CPU goes to step SP73, switches the left-cast casting indicated by the cursor CS (FIGS. 12A and 12B), and then goes to step SP51.

If the CPU obtains a negative result in step SP72, the CPU goes to step SP74 to display the left cast (FIG. 12A or FIG. 12B) instead of the currently displayed cast, After setting the animation mode, the flow goes to step SP51.

If the CPU obtains a negative result in step SP60, the CPU goes to step SP76 to determine whether the timer has been in a predetermined time.

If a negative result is obtained here, the CPU goes to step SP77 and determines whether the current animation mode is the right animation mode or not.

If an affirmative result is obtained here, the CPU goes to step SP70 to perform casting (step 12c or step 12d) instead of the currently displayed cast, puts the animation mode memory 31 into the right animation mode, (SP51).

If the CPU obtains a negative result at step SP77, the CPU goes to step SP78 and determines whether the current animation mode is the left animation mode or not.

If an affirmative result is obtained here, the CPU goes to step SP74 to perform a left cast (display of FIG. 12A or FIG. 12B, and sets the animation mode memory 31 to the left animation mode) (SP51).

When the CPU obtains a negative result in step SP78 or obtains an affirmative result in step SP76, the CPU proceeds to step SP79 and determines whether the current animation mode is the still animation mode.

If a negative result is obtained here, the CPU goes to step SP80 to display a still cast (Fig. 12e or 12f) instead of the currently displayed cast, and sets the animation mode memory 31 to the still animation mode The procedure goes to step SP51.

If the CPU obtains an affirmative result in step SP79, the CPU goes to step SP82 and switches the stationary cast (shown in FIG. 12E or 12F) indicated by the cursor CS. Then, the CPU goes to step SP51.

Then, the CPU goes to step SP51 to judge whether or not the view button 5 has been pressed again. If an affirmative result is obtained, the CPU goes to the next step SP52 and judges whether or not the search screen is at the end of display.

An affirmative result is obtained in two processes, and the CPU goes to step SP83 to cancel the search mode, and at the next step SP84, the search screen is cleared and the process goes to step SP51.

If a negative result is obtained in step SP51, the CPU goes to step SP85 to judge whether or not the search screen is at the end of display. If a negative result is obtained, the CPU goes to step SP51.

The view button 5 is actually used as a toggle switch by executing this processing and once the view button 5 is pressed, the view search screen is displayed to perform search processing. In this state, The view search screen is erased and the search process is stopped.

When the view button 5 is pressed again, the mode is set to display the view search screen and execute search processing.

If the CPU obtains an affirmative result in the above-mentioned step SP85, the processing loop of the steps SP58 to SP82 is executed again. If the CPU obtains an affirmative result in the step SP59, the CPU goes to the step SP86 It is determined whether or not the target playback position and the playback position are the same. If an affirmative result is obtained, the process goes to step SP51.

This is because the target playback position differs from the playback position as a result of the view searching process, so it is determined whether it is necessary to drive the magnetic tape by driving and rewinding the magnetic tape.

Subsequently, when a negative result is obtained in step SP86, the CPU goes to the next step SP87 and moves the magnetic tape to the VTR running control circuit 28 up to the frame indicated by the time code appended to the image index IDX which is the object playback position A search command is sent, and a search-in-progress screen process is performed to indicate that the search is being performed in step SP88, and then the view search process program SP50 is terminated in the next step SP89.

In the above configuration, for example, when the user presses the view button 5 during playback of the video tape recorder 1, the image index IDS in the vicinity of the playback position is displayed and arranged on the matrix on the display screen DSP of the color liquid crystal display 2 .

Accordingly, when the user arbitrarily rotates the roller 7, the cursor CS which moves the roller 7 to indicate the target playback position on the display screen DSP moves.

When the user depresses the display button 9 at the position where the target reproduction position is determined, the display is switched to the display DSP in the search process, and when the search is terminated, the reproduction screen starts from the target reproduction position. Thus, in the video tape recorder 1, it is possible to visually or intuitively search the target playback position while referring to the image index IDX on the display screen DSP, and the user's use state can be improved stepwise in the search processing.

(4) Search processing of rollers

(SP13) - (SP15) among the entire processing programs SP0 using the CPU image index IDX of the search control circuit 22 and the display screen generating circuit 25 of the video tape recorder 1 of this embodiment When the local button 6 is pressed, the local search processing program SP100 shown in FIG. 13 and FIG. 14 is executed.

In the local search processing, as shown in FIG. 15, the image index IDX of a predetermined number of times around the reproduction position on the magnetic tape, to which the current magnetic head is appropriately in contact, And displays it as an image band LB of the object, and designates the playback position targeted by the cursor CS.

At this time, each cell image of the image index IDX is followed by the order of the corresponding timer codes from left to right. A mark MK indicating a reproduction position on the image band LB and a cursor CS indicating an object reproduction position expressed in animation as a moving person, for example. When this cursor CS reaches the left end of the image band LB, the image band LB itself scrolls rightward by 1 in the image index IDX, and scrolls leftward by 1 in the opposite direction to the right end.

The CPU of the search control circuit 22 and the display screen generating circuit 25 in effect determines whether the local button 6 has been pressed from the local search processing program SP100 to the next step SP101, If YES, the process goes to the next step SP102 to determine whether or not the search screen is displayed.

In the first process, a negative result is obtained, and the CPU goes to step SP103.

In this step SP103, the CPU switches the reproduction screen displayed on the color liquid crystal display 2 to the search screen which is the display screen DSP for local search described in Fig. 15, and in the next step (SP104) The current playback position is set to the current playback position.

Subsequently, the CPU reads the stop cast from the animation icon memory 32 as shown in FIG. 12E or FIG. 12F, and displays it as a cursor CS.

In addition, the CPU executes step SP106 to set the animation mode memory 31 to the stopped animation mode in which the animation mode is set to the stopped state.

Next, based on the contents of the target image position memory 27 in step SP107, the CPU reads the image index IDX in the vicinity of the target playback position from the target playback position screen memory 33 and displays it on the display screen DSP in accordance with the time series The image band LB is displayed. Then, in step SP108, the mark MK is displayed at the position corresponding to the playback position, and the process goes to step SP109.

The CPU determines whether the display button 9 is pressed in step SP109. Normally, when the local button 6 is pressed and the display button 9 is pressed during the local search processing, it means that the magnetic tape is actually executed by completing the search processing. During the normal search processing, (SP110).

In this step SP110, it is determined whether or not the roller 7 is moved based on the rotation information of the on-roller 7 in the roller cursor position memory 24. If a negative result is obtained, the CPU goes to the next step SP111 , The timer 29 is reset to perform the display switching of the casting even when the rollers are not moved, and the process proceeds to the next step SP112.

In step SP112, the CPU determines whether the position of the cursor CS is the left end or the right end on the image vs. LB, and if the CPU CS obtains a negative result, the CPU proceeds to the next step SP114.

If the CPU obtains an affirmative result in the above-described step SP112, the CPU 11 goes to step SP115, scrolls the image band LB rightward and then goes to step SP114. If the CPU 11 obtains an affirmative result in step SP113, the CPU goes to step SP116 After the image band LB is scrolled, the process goes to step SP114.

In this step SP114, the CPU moves the cursor CS to the target playback position and determines whether or not the roller 7 has moved to the right in the next step SP117. Here, if an affirmative result is obtained, the CPU goes to step SP118 and refers to the animation mode memory 31 to determine whether the current animation mode is the right animation mode.

If an affirmative result is obtained here, the CPU goes to step SP119 to switch the right cast displayed in the cursor CS (FIG. 12C or FIG. 12D) and then goes to step SP101.

If the CPU obtains a negative result in step SP118, the CPU goes to step SP120 to display a cast (step 12c or 12d) instead of the currently displayed cast, and sets the animation mode memory 31 to the right After the animation mode is set, the flow goes to step SP101.

If a negative result is obtained in step SP117, the CPU goes to step SP112 and refers to the animation mode memory 31 to determine whether the current animation mode is the left animation mode. If an affirmative result is obtained here, the CPU goes to step SP123 and goes to step SP101 after switching the left cast (indicated by the cursor CS in FIG. 12A or FIG. 12B).

If the CPU obtains a negative result in step SP122, the CPU goes to step SP124 to display a left cast (FIG. 12A or FIG. 12B) instead of the cast currently being displayed and sets the animation mode memory 31 The process proceeds to step SP101 after setting the left animation mode.

If the CPU obtains a negative result in step SP110, the CPU goes to step SP126 and determines whether or not the timer is a predetermined time. Here, if a negative result is obtained, the CPU goes to step SP127 and determines whether the current animation mode is the right animation mode or not.

Here, the CPU obtains an affirmative result, and the CPU goes to step SP120 to change the animation mode memory 31 to the right animation mode, instead of displaying the currently casting cast (step 12c or step 12d, SP101).

If the CPU obtains a negative result in step SP127, the CPU proceeds to step SP128 and determines whether the current animation mode is the left animation mode. Here, if an affirmative result is obtained, the CPU goes to step SP124 to display a left cast (12th degree or 12th degree) instead of the currently displayed cast, sets the animation mode memory 31 to the left animation mode The procedure goes to step SP101.

If the CPU obtains a negative result in step SP128 or obtains an affirmative result in step SP126, the CPU proceeds to step SP129 and determines whether the current animation mode is the still animation mode. Here, if a negative result is obtained, the CPU goes to step SP130 to display a still cast (Fig. 12e or 12f) instead of the currently displayed cast, and sets the animation mode memory 31 to the still animation mode The process goes to step SP101.

If the CPU obtains an affirmative result in step SP129, the CPU goes to step SP132 to switch the stationary cast displayed as the cursor CS (Fig. 12E or 12F), and then goes to step SP101.

Then, the CPU goes to step SP101 to determine whether the local button 6 has been pressed again. If the CPU 6 obtains an affirmative result, the CPU goes to the next step SP102 and determines whether or not the search screen is displayed.

In the second process, an affirmative result is obtained, and the CPU goes to step SP133 to cancel the search mode, and at the next step (SP134), the search screen is cleared, and the process goes to step SP101.

If a negative result is obtained at step SP101, the CPU goes to step SP135 to judge whether or not the search screen is at the end of display, and if the result is negative, the CPU goes to step SP101.

The local button 6 is used as a toggle switch and the local button 6 is pressed once to display the local search screen and the search process is executed. When the local button 6 is pressed again in the ideal state The local search screen is erased and the search process is stopped. When the local button 6 is pressed again, the local search screen is displayed and the search process is executed.

If the CPU obtains an affirmative result in the above-mentioned step SP135, the processing loop of the steps SP108-SP132 is executed again. If the CPU obtains an affirmative result in the step SP109, the CPU goes to the step SP136, It is determined whether or not the position is the same as the reproduction position, and if an affirmative result is obtained, the process goes to the above-mentioned step SP101.

This is because the target playback position differs from the current playback position as a result of the local search processing, so it is determined whether the magnetic tape needs to be driven and retrieved by actually composing or rewinding the magnetic tape.

If a negative result is obtained at this step SP136, the CPU goes to the next step SP137 to move the magnetic tape to the VTR running control circuit 28 up to the frame represented by the timer code appended to the image index IDX, which is the target playback position Send a search command.

Subsequently, a search in-screen process is performed indicating that the search is being performed in step SP138, and then the local search process program SP100 is terminated in the next step SP139.

For example, when the user inserts the local button 6 during playback of the video tape recorder 1 in the above configuration, the local button 6 is superimposed on the playback screen VD on the display screen DSP of the color liquid crystal display 2, LB is displayed.

Thus, the user arbitrarily rotates the roller 7 and moves the cursor CS indicating the target playback position on the displayed DSP in response to the rotation of the roller 7.

When the target playback position is determined, the user presses the display button 9 and switches to the screen display during the search process. When the search ends, the playback screen starts from the target playback position.

Thus, when the playback position and the target playback position are relatively close to each other while referring to the image band LB which is the image index IDX on the display screen DSP in the video tape recorder 1, it is possible to search the target playback position once visually or sensibly And the use state of the user can be stepped up during the search process.

(5) Global search processing

The CPU of the search control circuit 22 and the display screen creation circuit 25 of the video tape recorder 1 of this embodiment performs the search processing of the steps SP13 to SP15 among the entire processing programs SP0 using the image index IDX, When the global button 4 is pressed, the globe search processing program SP150 shown in Figs. 16 and 17 is executed.

18, a scale SK indicating the reproducible area on the magnetic tape is superimposed on the video image VD displayed on the display screen DSP, and the scale SK is displayed on the scale SK by the cursor CS This is a search process for indicating a target playback position.

At this time, the first reproducible position TT is arranged at the left end of the scale SK, and the last position TE reproducible at the right end is associated with the scale SK. Further, a mark MK for indicating the playback position and a cursor CS for displaying the target playback position are displayed on the scale SK, and a small screen V0B is displayed on the cursor CS for the image index of the target playback position.

The CPU of the search control circuit 22 and the display screen generating circuit 25 determines whether the global button 4 is pushed in the global search processing program SP150 to the next step SP151, The flow goes to step SP152 to determine whether or not the search screen is at the end of display.

If a negative result is obtained at the first processing, the CPU goes to step SP153.

In this step SP153, the CPU switches the reproduction screen displayed on the color liquid crystal display 2 to the search screen which is the display screen DSP for global search described in Fig. 18, The current playback position is set in the position memory 27. [

Subsequently, the CPU reads the stop cast shown in FIG. 12E or FIG. 12F from the animation icon memory 32 and displays it as a cursor CS.

In addition, the CPU executes step SP156 to set the animation mode memory 31 to the stopped animation mode in which it is stopped.

Next, based on the contents of the target image position memory 27 in step SP157, the CPU reads the image index IDX closest to the target playback position from the target playback position screen memory 33 and displays it on the small screen V0B Subsequently, in step SP158, the mark MK is displayed at the position corresponding to the reproduction position, and the process goes to step SP159.

The CPU determines whether or not the display button 9 is pressed in this step SP159. Since the global button 4 is pressed and the display button 9 is pressed during the global search processing, it means that the search processing is actually completed and the magnetic tape is actually executed, so that during the normal search processing, a negative result is obtained and the CPU The process goes to step SP160.

In this step SP160, based on the rotation information of the roller 7 inputted from the roller cursor position memory 26, it is determined whether or not the roller 7 has moved. If the CPU 7 obtains a negative result, the CPU proceeds to the next step , The timer 29 is reset to perform the display switching of the casting even when the rollers are not moving, and the process goes to the next step SP162.

The CPU determines whether or not the position of the cursor CS is within the scale SK at this step SP162. If the CPU obtains a negative result at this step SP162, the CPU executes the next step SP163 to correct the position of the cursor CS on the scale SK, (SP164). On the other hand, if an affirmative result is obtained in step SP162, the process directly proceeds to step SP164.

In this step SP164, the CPU moves the cursor CS to the target playback position and determines whether or not the roller 7 has moved to the right in the next step SP167. If an affirmative result is obtained, the CPU moves to step SP168 and refers to the animation mode memory 31 to determine whether the current animation mode is the right animation mode. Here, if an affirmative result is obtained, the CPU goes to step SP169, switches the right cast displayed as the cursor CS (FIG. 12C or FIG. 12D), and then goes to step SP165.

If the CPU obtains a negative result at step SP168, the CPU goes to step SP170 to replace the currently displayed cast, and displays the right cast (FIG. 12C or FIG. 12D) After setting the animation mode, the flow advances to step SP165.

If a negative result is obtained at step SP167, the CPU goes to step SP172 and refers to the animation mode memory 31 to determine whether the current animation mode is the left animation mode.

Here, if an affirmative result is obtained, the CPU goes to step SP173 and switches the left-cast (the figure 12a or 12b) indicated as the cursor CS, and then goes to step SP165.

If the CPU obtains a negative result in step SP172, the CPU goes to step SP174 to display the left cast (FIG. 12A or FIG. 12B) instead of the currently displayed cast, and sets the animation mode memory 31 The process proceeds to step SP165 after setting the left animation mode.

If the CPU obtains a negative result in step SP160, the CPU goes to step SP176 and determines whether the timer has reached a predetermined time.

Here, if a negative result is obtained, the CPU goes to step SP177 and determines whether the current animation mode is the right animation mode.

If an affirmative result is obtained here, the CPU goes to step SP170 to display a cast (step 12c or 12d) instead of the currently displayed cast, puts the animation mode memory 31 in the right-hand animation mode, SP165).

If the CPU obtains a negative result at step SP177, the CPU goes to step SP178 and determines whether the current animation mode is the left animation mode or not.

Here, if an affirmative result is obtained, the CPU goes to step SP174 to display the left cast (FIG. 12A or FIG. 12B) instead of the currently displayed cast, sets the animation mode memory 31 to the left animation mode, (SP165).

In fact, in step SP165 and the other step SP166, the CPU calculates the target playback position at the position of the cursor CS, reads the image index IDX closest to the target playback position in the target playback position screen memory 33, V0B, and then goes to the above-mentioned step SP151.

If the CPU obtains a negative result in step SP178 or obtains an affirmative result in step SP176, the CPU proceeds to step SP179 and determines whether the current animation mode is the still animation mode. Here, if a negative result is obtained, the CPU goes to step SP180 to display a still cast (Fig. 12e or 12f) in place of the currently displayed cast, puts the animation mode memory 31 into the still animation mode, (SP151).

If the CPU obtains an affirmative result in step SP179, the CPU goes to step SP182, switches the stationary cast (also shown in FIG. 12E or 12F) indicated by the cursor CS, and then goes to step SP151.

Then, the CPU goes to step SP151 to determine whether the global button 4 has been pressed again. If the CPU 4 obtains an affirmative result, the CPU goes to the next step SP152 and determines whether or not the search screen is displayed.

In the second process, an affirmative result is obtained, and the CPU goes to step SP183 to cancel the search mode, and at the next step SP184, the search screen is cleared and the process goes to step SP151.

If a negative result is obtained at step SP151, the CPU goes to step SP185 to determine whether or not the search screen is at the end of display. If the result is negative at this step SP151, the CPU goes to step SP151.

The global button 4 is used as a toggle switch, and once the global button 4 is pressed, the global search screen is displayed and the search process is performed. In this state, the global button 4 4) is pressed, the global search screen is erased and search processing is stopped.

When the global button 4 is pressed again, the global search screen is displayed and the search process is executed.

If the CPU obtains an affirmative result in the above-mentioned step SP185, the processing loop of the step SP158 to the step SP182 is executed once again. If the CPU obtains an affirmative result in the step SP159, the CPU goes to the step SP186 It is determined whether the target playback position is the same as the playback position, and the process goes to the above-mentioned step SP151a for obtaining an affirmative result. This is because the target playback position is different from the current playback position as a result of the global search processing, so it is judged whether or not it is necessary to drive the magnetic tape by driving and rewinding the magnetic tape.

If a negative result is obtained at this step SP186, the CPU goes to the next step SP187 and searches the VTR running control circuit 28 for a search for moving the magnetic tape to the frame indicated by the timer code added to the image index IDX A search is made during the search process indicating that the search is being performed in step SP188, and then the global search process program SP150 is terminated in the next step SP189.

For example, when the user presses the global button 4 during playback of the video tape recorder 1, the scale SK, which is a reproducible area superimposed on the playback screen VD on the display screen DSP of the color liquid crystal display 2, do.

Accordingly, when the user rotates the roller 7 arbitrarily, the cursor CS that moves the roller 7 indicating the target playback position on the display screen DSP is moved.

When the user depresses the display button 9 when the target playback position is determined, the screen is switched to the screen display during the search process, and when the search ends, the screen becomes the playback screen at the target playback position.

Thus, in the video tape recorder 1, the target playback position can be searched visually or intuitively with respect to the whole magnetic tape while referring to the scale SK on the display screen DSP and the display on the small screen V0B, The use state of the user can be improved step by step.

(6) Index image processing apparatus

The CPU of the search control circuit 22 and the display screen creation circuit 25 of the video tape recorder 1 of this embodiment is constituted by a view search processing program SP50, a local search processing program SP100, a global search processing program SP150, The index image display processing program SP200 shown in Fig. 19 is executed as the search screen processing of the respective steps SP89, SP139 and SP189 of Fig.

Here, in the index image display processing, the index image in the vicinity of the pass position during stopping, searching, or fast forwarding or rewinding is displayed on the video tape recorder 1.

In this case, as shown in FIG. 20, for example, a scale SK indicating a reproducible area on the magnetic tape together with, for example, a global indication is displayed on the display screen DSP, and a first reproducible position TT is arranged at the left end of the scale SK And corresponds to the last position TE that can be reproduced on the right end. A current position mark MK indicating a reproducible position on the scale SK and a mark MK2 indicating a target reproduction position in the search are positioned.

In the center of the display screen DSP, an index image IDF in the vicinity of the presently reproducible position is displayed. In the case of the direction in which the target playback position is rewound compared with the currently reproducible position in the search, the left side is displayed. The index image IDG is displayed.

Further, the operation state of the current VCR mechanism 35 is displayed according to the animation AN. This is an animation that moves while moving in the traveling direction of the VCR mechadic 35 in the case of searching, fast forwarding or rewinding, while walking while walking. Then, the state in which the cassette tape is taken out is displayed in the animation.

The CPU of the actual image search control circuit 22 and the display screen generating circuit 25 starts from the index screen display processing program SP200 and displays the global display And the scale SK is displayed at a predetermined position. In step SP201, the CPU checks the operation state of the VCR mechanism 35 to determine whether a cassette tape has been received.

If a negative result is obtained at step SP201, the CPU goes to step SP202 to display the animation showing the cassette tape take-out state on the display screen DSP, and goes to step SP201 to judge that the cassette tape has been loaded .

If an affirmative result is obtained at step SP201, the CPU goes to step SP203. In this step SP203, the index image IDF of the current position is displayed in the center of the display screen DSP, and the process goes to the next step (SP204).

In this step SP204, the CPU checks the operation state of the VCR mechanism 35 to judge whether the magnetic tape is in the fast state. Here, if an affirmative result is obtained, the CPU goes to step SP205 to display the composition animation, and then goes to step SP204.

This animation is realized by, for example, sequentially switching the right cast (FIG. 12C or FIG. 12D) described in FIG. 12 so that the character faces rightward. If a negative result is obtained at this step SP204, the CPU goes to the next step (SP206).

In step SP206, the CPU checks the operation state of the VCR mechanism 35 to determine whether or not the magnetic tape has been rewound. Here, if an affirmative result is obtained, the CPU goes to step SP207 to display the rewound animation, and then goes to step SP206.

The rewound animation realizes animation such that, for example, the left-cast (as shown in FIG. 12A or FIG. 12B) described above in FIG. 12 is sequentially switched so that the character goes leftward.

If this step obtains a negative result (SP206), the CPU proceeds to the next step (SP208).

At this step SP208, the operating state of the CPU SMS VTR mechanism 35 is checked to determine whether the magnetic tape is in the stationary state.

If an affirmative result is obtained here, the CPU goes to step SP209 to display the stop animation and then goes to step SP208.

This still animation realizes an animation such that the character is turned toward the front by sequentially switching the still cast (FIG. 12E or 12F) described in FIG. 12, for example. If a negative result is obtained at this step SP208, the CPU proceeds to the next step SP210

.

In this step SP210, the CPU determines whether the current operation state is the search state or not in each of the steps SP89, SP139, SP189 of the view search processing program (SP50) local search processing program (SP100) It is determined whether or not the index image display processing program SP200 has been executed as the search screen processing.

If an affirmative result is obtained in step SP210, the CPU goes to step SP211 and determines whether the target playback position as the search result is the rewind direction.

Here, if an affirmative result is obtained, the CPU goes to step SP212 to display the index image IDG of the object playback position on the left side of the display screen DSP and rewinds it in the next step SP213 to display the animation. In the next step SP214 It is determined whether or not the search has been completed.

Whether or not the search is completed determines whether the current position matches the target playback position. If a negative result is obtained, the CPU proceeds to step SP213.

If an affirmative result is obtained at this step SP214, the CPU goes to step SP215.

When the CPU obtains a negative result in step SP211, the CPU goes to the next step SP216 to display the objective reproduction position index image IDG on the right side of the display screen DSP, displays the fast animation in the next step SP217, SP 218) determines whether the search has been completed.

Whether or not the search is completed determines whether the current position matches the target playback position. If a negative result is obtained, the CPU proceeds to step SP217.

If an affirmative result is obtained at this step SP218, the CPU goes to step SP215.

In step SP215, the CPU displays a playback screen corresponding to the target playback position as a search result, and then ends the index image display processing program SP200 in the next step (SP219). When obtaining a negative result in the above-mentioned step SP210, the CPU directly goes to step SP219 and ends the index image display processing program SP200.

When the user operates stop, fast forward or reverse in the video tape recorder 1, the index image and the predetermined animation in the vicinity of the passing position are displayed and, in particular, the index image in the vicinity of the current position and the target playback position And a predetermined animation indicating its search direction are displayed.

Accordingly, the user can visually or sensibly recognize the operation state of the video tape recorder 1 by viewing the display screen.
