Abstract

PROBLEM TO BE SOLVED: To provide an apparatus, for the recording and reproducing operation of an image, by which the output of a title image can be turned on and off and by which the tile image can be erased although a system by which the title image multiplexed with a static image in the recording region of image information is recording as it is adopted. SOLUTION: A microcomputer 34 records an image, plotted on a touch panel 42, for a short time in such a way that the image is not multiplexed with a static image (a first static image) obtained from a camera 35 by an image multiplexing circuit 38. Immediately after that, it records a static image (a second static image) in which a handwritten image is multiplexed with the first static image. Thereby, both an original image and a multiplexed image are recorded on a magnetic tape 31. In a reproducing operation, when the first static image is selected, the first static image is fixed to a memory inside the image multiplexing circuit 38, its display is continued, and the second static image is not displayed. When the second static image is selected, it is controlled that the first static image is not displayed and that the second static image is displayed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an image recording apparatus and an image reproducing apparatus for recording and reproducing image information on a recording medium such as a magnetic tape.

[0002]

2. Description of the Related Art The problem with shooting with a conventional video camera or the like is that when a comment or title is added to a shot scene, a dedicated device is purchased and dubbing is performed later to add a title. Also, there was no alternative but to write the title on a piece of paper and shoot it with a camera.

In order to solve the above problem, Japanese Patent Laid-Open No.
No. 472 discloses a camera-integrated VTR with a monitor.
A technology is disclosed in which a touch panel is attached to a VTR, a title of a scene is input by pen input, and a character signal is recorded on a magnetic tape of a VTR in an area different from an image signal.

Japanese Patent Laid-Open Publication No. Hei 3-24870 discloses a technique for recording a superimposed image on a sub-track different from an image track. As a method of recording additional information in an area different from an image signal, a consumer digital VCR standard (hereinafter, referred to as a DV standard), which is currently becoming the mainstream of home video camera systems, will be described.

FIG. 13 is a diagram schematically showing a track pattern, wherein 1 is a magnetic tape as a recording medium,
Indicates the direction in which the tape runs, and arrow 3 indicates the direction in which the head scans. 4 is ITI (Insert and
Track Information) Sector, 5 is A
audio sector, 6 is Video sector, 7 is Subc
mode sector. In the case of the 525/60 system, one frame of image / audio data is composed of 10 tracks,
The track numbers are from 0 to 9.

Each area has a sync block unit, and the number of valid sync blocks is 14 sync blocks per track in the Audio sector, and 1 in the Video sector.
There are 49 sync blocks and 12 sync blocks in the subcode sector. One sync block is 90 bytes in Audio and Video sectors, and Subcode
In the e-sector, it is 12 bytes.

FIG. 14 is a diagram schematically showing the structure of a video sector. The effective areas of the video sector are sync block numbers 19 to 167. Reference numeral 11 denotes an area in which a predetermined sync pattern is recorded, which is 2 bytes for each sync block. Reference numeral 12 denotes an area in which ID data is recorded, which is 3 bytes for each sync block. 1
Reference numeral 3 denotes an area in which VAUX is recorded. VAUX (auxiliary data relating to video data) is stored in a data area (77 bytes) of a sync block having sync block numbers 19, 20, and 156. Reference numeral 14 denotes video data, and 77 bytes of data are stored in each sync block. Reference numeral 15 denotes parity for error correction, which is the latter 8 bytes of each sync block and sync block numbers 157 to 1.
Parity is to be entered in 67 areas.

The area where VAUX is recorded is 77 bytes per sync block, but the recorded data is 5 bytes.
Since the pack structure has one byte as a pack, 75 bytes (= 15 packs) are actually used, so that 45 packs can be recorded per track.

In the case of a track with an odd track number, the first six packs of the area of the sync block number 19 are used. In the case of a track with an even track number, the latter six packs of the area of the sync block number 156 are used as the main area. A prescribed pack is to be written. Areas other than the main area are optional areas, and in principle, packs can be freely written. Therefore, by subtracting 12 packs of the main area, the optional area is 33 per track.
Pack = 330 packs per frame.

FIG. 15 is a diagram schematically showing the structure of a subcode sector. Reference numeral 21 denotes an area in which a predetermined sync pattern is recorded, which is 2 bytes for each sync block. Reference numeral 22 denotes an area where ID data is recorded, which is 3 bytes for each sync block. Reference numeral 23 denotes an area in which subcode data is recorded. The area is 5 bytes per sync block. Since this area also has a pack structure similar to VAUX, one area is provided for one pack per sync block. 24 is a parity for error correction.

In the sub-code data, areas having sync block numbers of 3, 4, 5, 9, 10, and 11 are defined as a main area, and information such as a time code and a recording date and time are recorded. An optional area,
In principle, packs can be freely recorded. However, in the first five tracks of the ten tracks constituting one frame, the same pack for each track is rearranged and repeatedly recorded, and the latter five tracks are repeatedly recorded.
Similarly, the same pack is rearranged and recorded on the track. FIG. 16 shows a recording method of the subcode data. The katakana indicates the optional area, and the hiragana indicates the main area. Where the same kana is recorded, the same pack must be recorded. 12 packs can be recorded in the area.

[0012] The standard of the consumer digital VCR is MIC (Memory In Cassette).
A non-volatile memory is attached to a cassette containing a magnetic tape so that TOC information and the like can be managed. The memory attached to the cassette has four terminals of power supply, GND, clock, and data, and performs communication by two-wire serial. The communication protocol uses I2C. A pack structure is used to record data in the memory in the same manner as subcode data and VAUX. The main area in which predetermined data must be recorded is the first 16 bytes of the memory, and the 17th and subsequent bytes are optional areas. As a general rule, packs can be freely recorded.

The above is the description of the DV standard.
For details, see "Specification of Consumer-Use Digital VCRs" issued by HD DIGITAL VCRCONFERENCE.
using 6.3mm magnetic tape "(hereinafter referred to as DVC standard).

[0014]

SUMMARY OF THE INVENTION Using the above technique, a DV
When recording a title image with a standard video camera, it is usually sufficient to record the title image information pack in an optional area such as a VAUX or subcode where a pack without information is recorded. Can be realized without the need.

However, as described above, even a VAUX in which the most information can be recorded is 330
This is a pack, and only about 1300 bytes can be recorded per frame except for the pack header.

On the other hand, if the screen resolution of the title image data is 720 × 480 (the same as the resolution of the DV standard), 720 × 480 × 4 = 1 even if the color information is 4 bits.
382400 bits = approximately 170 Kbytes. If simply recorded, it is necessary to record for 4 seconds or more, and a title image will not be output unless 4 seconds or more have elapsed since the scene in which the title was recorded started. I will.

Further, in a situation where a title is input before shooting a scene, a still image is fixed in a memory, and a problem that characters to be viewed and characters are overlapped by inputting with a pen on the still image is avoided. The method of recording a still image with characters superimposed thereon as a title image for several seconds before shooting a scene is reasonable without the need for additional special hardware.

However, if a still image with characters superimposed is recorded in the image recording area as it is, no title image is required, and it is not possible to meet the desire to view only the original still image. There is a problem that it is not possible to meet a request to delete an image.

Reference numeral 5 denotes a speaker that converts an audio signal output from the reproduction signal processing circuit 37 into audio and outputs the audio.

The DVC of this embodiment has a recording / reproducing function similar to that of a general camera-integrated VTR, and also has a camera 35 that is capable of inputting image data input on a touch panel 42 with a pen.
In order to realize the function of recording on the magnetic tape 31 together with the still image data obtained from the touch panel, the touch position decoding circuit 43 converts the point pressed on the touch panel 42 into coordinate information, sends the coordinate information to the microcomputer 34, and the microcomputer 34 The information of the position to be drawn on the screen is transmitted to the image multiplexing circuit 38,

Also at the time of reproduction, an image with drawing information or an original image without drawing information The user selects which of the two is to be displayed, and the microcomputer 34 controls the tape drive circuit 44 to reproduce a desired image.

(Operation of Recording System) Then, first, as the operation of the recording system, the configuration and operation of the image multiplexing circuit 38, the display operation of drawing data, the touch position detection operation, the operation at the time of normal image recording, and finally the present invention The operation at the time of writing the drawing data, which is the point, will be described.

FIG. 2 is a block diagram showing the internal configuration of the image multiplexing circuit 38. Reference numeral 51 denotes a drawing information decoding unit which decodes drawing information sent from the microcomputer 34 and outputs it as image data. , A drawing memory for storing the image information output by, and a frame memory 53 for storing the image information, which has a storage area for two frames. Reference numeral 54 denotes a memory writing control unit for writing image information sent from the camera 35 by selecting a surface of the frame memory 53, and stopping writing according to an instruction from the microcomputer 34 and outputting a still image from the frame memory 53.

The display data multiplexing unit 58 receives data output from the drawing memory readout unit 56 and outputs image data to be displayed. The display data multiplexing unit 58 receives data output from the frame memory readout unit 55 and the drawing memory readout unit 56. A recording image data multiplexing unit that outputs image data to be recorded according to an instruction from the microcomputer 34.

The image data output from the camera 35 is stored in the frame memory 53 by the memory writing control unit 54. On the other hand, the drawing information sent from the microcomputer 34 is converted into actual image data by the drawing information decoding unit and stored in the drawing memory 52. The drawing information sent from the microcomputer 34 includes coordinate information when one screen is divided into 720 horizontal pixels × 480 vertical pixels, and ON / OFF information.
2 bytes of abscissa + 2 bytes of ordinate + ON / OFF information 1
This is 5 bytes. Thereby, the drawing information decoding unit 51 turns ON / OF the bit at the position indicated by the coordinate information.
F is good. This means that information necessary for display and recording is stored in each memory.

Next, a description will be given of a process for displaying the drawing data by overlaying it with the image information obtained from the camera 35. FIG. The frame memory reading unit 55 reads out data on a surface of the frame memory 53 that is not accessed by the memory writing control unit 54, and outputs the data to the display data multiplexing unit. At the same timing, data in the drawing memory 52 corresponding to the same location on the screen
6 reads. To adjust the timing, a synchronization signal (not shown) given from the camera 35 is given to the frame memory reading unit 55 and the drawing memory reading unit 56,
This is performed by adjusting the read start timing of each memory. If the data obtained from the drawing memory reading unit 56 indicates that drawing is ON, the display data multiplexing unit 57 sets the color of the pixel being read to white and outputs it to the display circuit 40, and indicates that drawing is OFF. For example, the image information obtained from the frame memory reading unit 55 is output to the display circuit 40 as it is.

In this manner, the handwritten image created from the coordinate information specified by the microcomputer 34 is transferred to the camera 35.
However, if the capacity of the drawing memory 52 is increased so that color information can be stored, a color handwritten image can be displayed.

Next, the operation during normal recording will be described. The recording data multiplexing unit 58 has two types of modes: a camera-through mode and a handwritten image multiplexing mode.
The selection is made according to an instruction from the microcomputer 34.

In the handwritten image multiplexing mode, the same processing as in the above-described display data multiplexing section 57 is performed to output and record image information to the recording signal processing circuit 39. In the camera through mode, the drawing memory is used. By ignoring all the information from the reading unit 56 and outputting and recording all the data from the frame memory reading unit 55 to the recording signal processing circuit 39, the image data output by the camera 35 is recorded as it is. Thus, the microcomputer 34 can select whether to multiplex the handwritten image with the image of the camera 35 at the time of recording.

Next, a process in which the microcomputer 34 acquires a position pressed on the touch panel 42 as coordinate information will be described. The microcomputer 34 in a state of waiting for input of the coordinate information from the touch position decoding circuit 43 obtains the coordinate information from the touch position decoding circuit 43 and sends the coordinate information to the image multiplexing circuit 38, so that the display circuit 40 Is displayed on the liquid crystal panel 41 via. This allows the user to check the characters and pictures drawn by him.

First, the operation of the touch position decoding circuit 43 will be briefly described. The specific circuit and sampling process are the same as those of the conventionally used touch panel, as described above, and thus will not be described. Since the touch position decoding circuit 43 has an 8-bit A / D converter, the resolution is 256 × 256 pixels. The touch position decoding circuit 43 performs sampling once every 10 msec, and obtains the coordinate values of the pressed X and Y to obtain X (horizontal).
Three values, that is, a value of 0 to 255 for the direction, a value of 0 to 255 for the Y (vertical) direction, and a pen state (pressed / continuously pressed / released) are transmitted. Actually, pressed = 11h, pressed = A
A state code of Ah, separated = 77h is used, and three bytes are set as one set, and the state code, the X coordinate, and the Y coordinate are transmitted in order of start-stop synchronization. Baud rate is 9600b
ps. FIG. 3 shows an example of a communication timing chart.

FIG. 3 shows that from the position (10, 10),
This figure shows the state of communication when a straight line is drawn up to the position (100, 100). When a pen press is detected, the first byte of communication is set to 11h and three bytes are transmitted. After the elapse of 10 ms, the pen is still pressed, so that the first byte of the communication is set to AAh and the coordinate information is continuously sent. Finally, when the pen is released, the first communication
The byte is set to 77h and the last coordinate is transmitted again. 77
After transmitting 3 bytes with h as the header, communication is not performed until the next pen press is detected.

The microcomputer 34 always operates the serial interface so that it can respond to communication at any timing, and interrupts when one or three bytes are received.

Next, how the microcomputer 34 converts the coordinate information into coordinate information to be sent to the image multiplexing circuit 38 will be described. As described above, the image multiplexing circuit 38
An image with a resolution of 0 × 480 pixels is output. Therefore, the microcomputer 34 must convert the coordinate information obtained at a resolution of 256.times.256, and display the line drawn thick to make it look good. Therefore, the coordinates for display are Xdisp and Ydisp, and the coordinates obtained from the touch position decoding circuit 43 are Xpen and Ypen.
Then

[0053]

(Equation 1)

Xdisp and Ydisp are obtained as follows.
Then, to make the displayed line thicker, Xdisp, Yd
The coordinate value painted white when isp is specified is (Wx
(Xdisp), Wy (Ydisp)), (X
disp, Ydisp), the area of a circle centered on

[0055]

(Equation 2)

Is as follows. The microcomputer 34 performs image multiplexing on the image multiplexing circuit 38 so as to paint all the points in the area designated by (Equation 2) white.
Must be sent to the image multiplexing circuit 38.

The microcomputer 34 sends the coordinate information obtained from the touch position decoding circuit 43 to the image multiplexing circuit 38 as described above.
The following describes processing for overlaying a handwritten image drawn on the touch panel 42 and recording the image.

As a user's operation, a handwritten image input mode is set by operating a button (not shown) or pressing the touch panel, a handwritten image is input on the touch panel 42 with a pen, and another recording button is pressed. The operation is to record the image drawn on the tape 31.

When the microcomputer 34 receives a request for the handwriting mode from the user, the microcomputer 34 instructs the memory writing control unit 54 in FIG. 2 at that point to stop writing new information to the frame memory 53, and a still image is output. So that By doing so, the fixed image is continuously displayed on the liquid crystal panel 41. Then, the image drawn by the above-described processing is displayed on the liquid crystal panel 41. When the drawing is completed and the button is pressed, the recording processing is performed.

When the recording button is pressed, the microcomputer 34 stops the reception from the touch position decoding circuit 43 and instructs the recording data multiplexing section 58 of the image multiplexing circuit 38 to record only the still image in the frame memory 53. 39 so that the handwritten image in the drawing memory 52 is not output. Then, it instructs the recording signal processing circuit 39 and the tape drive circuit 44 to start recording. At this time,
The voice data obtained from the microphone 36 is also recorded.

After the start of recording, the recording is continued for 15 frames (0.5 seconds). From the 16th frame, the recording data multiplexing unit 58 is instructed to stop the handwritten image in the drawing memory 52 and the still image in the frame memory 53. The image signal in which the image is multiplexed is output to the recording signal processing circuit 39, and the image in which the handwritten image is multiplexed starts to be recorded, and continues to be recorded for 150 frames (5 seconds).

If a still image in which a handwritten image is not multiplexed is a first still image, and a still image in which a handwritten image is multiplexed is a second still image, 15 frames of the first still image and 15 frames of the second still image After recording 150 frames, the microcomputer 34 instructs the recording signal processing circuit 39 to record, as a marker, a pack indicating the area immediately before the handwritten image is recorded in the subcode area of the first still image recording area ( The details will be described later), and the PP ID is recorded in the subcode area of the recording area of the second still image. The PP ID is a marker indicating that a still image has been recorded, and is recorded in the ID area of the subcode area for 150 to 152 frames. Here, 150 frames are recorded to indicate the second still image. FIG. 4 shows the recording results of the first still image and the second still image.

In the subcode area of the recording area of the first still image, a pack indicating that it is an area immediately before the handwritten image is recorded is recorded. The method will be described. To record a pack devised freely in the subcode area, use MA
A KER CODE pack (pack header = F0h) is used to record a handwritten image pack (pack header = F1h) indicating an area immediately before a handwritten image is recorded as an OPTION pack. Here, a pack whose pack header is F1h is referred to as a handwritten image pack. FIG. 5 shows the contents of the MAKER CODE pack, and FIG. 6 shows the contents of the handwritten image pack.

In FIG. 5, reference numeral 61 denotes a pack header.
It is fixed at 0h. Reference numeral 62 denotes a maker code in which a maker code for making a DVC using a maker option is entered. Here, it is temporarily set to 02h. An area 63 stores the number of all packs. This area indicates how many areas occupied by the manufacturer indicated by 62 will follow this maker code pack. If a subcode area is used, one frame indicates Since it is completed, a maximum of 11 packs can be continued. 64 and 65 are empty areas in the DVC standard, but here (when the maker code is 02h), 64 is set as a reserved area, all bits are filled with 1, and 65 is set as 01h as a format code. That is, when the format code is 01h, a pack whose pack header is F1h is defined as a handwritten image pack.

In the area after the maker option pack is recorded (in the same frame if it is a subcode area), the maker specified by the maker code is free for the range specified by the maker code.
ON packs can be arranged. The OPTION pack is a pack whose pack header is F1h to FEh.

In FIG. 6, reference numeral 71 denotes a pack header.
It is fixed for 1 h. The maker code 62, the format code 65 and the pack header 71 indicate that the pack is a handwritten image pack. Reference numeral 72 denotes a bit indicating whether or not the handwritten image is multiplexed. When 1 is set, the handwritten image is multiplexed on the image in which this pack is recorded, and when 0, it is not multiplexed. .
Reference numeral 73 denotes a still image that follows, that is, an image in which the handwritten image is not multiplexed when the bit 72 is 1, an image in which the handwritten image is multiplexed when the bit 72 is 0, and a second image in the present embodiment.
Is the data indicating how many frames are recorded after the still image in which this pack is recorded. The maximum is 255 frames. In the present embodiment, bit 7
2 becomes 0, and the data 73 contains 96h in hexadecimal (150 in decimal). Reference numeral 74 denotes a reserved area in which all bits are set to 1.

As described above, the first still image in which the handwritten image is not multiplexed and the second still image in which the handwritten image is multiplexed are recorded, so that the handwritten image is multiplexed even during normal reproduction. It is also possible to see a second still image,
Further, the still image in which the handwritten image is not multiplexed can be viewed by performing still in the reproduction area of the first still image.

Here, 15 frames of the first still image and 150 frames of the second still image are recorded. However, the time for which the reproduction of the first still image is not bothersome is as follows.
Also, the time may be set so long as it does not become impossible to reproduce due to an error or the like at the time of reproduction, and may be set to any number of frames from several frames to about one second. May be set to any number of frames as long as the time for reproducing is appropriate. However, in the handwritten image pack according to the present embodiment, since the number of frames of the second still image is set by the data 73 in FIG. 6, it cannot be longer than 255 frames. If it is desired to set the length to exceed 255 frames, it is necessary to change the data 73 to 2 bytes.

Although the number of recording frames of the second still image is recorded in the handwritten image pack, the second handwritten image pack is created, for example, as a pack header = F2h, and the subcode of the recording region of the second still image is used. A method of recording together with the MAKER CODE pack or a method of determining the number of recording frames of the second still image when the first still image and the handwritten image pack are recorded, for example, to be fixed to 150 frames may be used.

Further, the second still image may be recorded together with the third handwritten image pack first, and then the first still image may be recorded thereafter. After all, the first still image and the second still image may be recorded. An image is recorded adjacently, and a marker such as a handwritten image pack is recorded in a subcode area or a VAUX area of the previously recorded one so that the boundary point between the first and second still images can be identified, It suffices if the still image is recorded so that the last frame of the still image to be recorded later, such as the number of frames recorded in the image pack, can be determined.

(Operation of Reproduction System) Next, the operation at the time of reproduction will be described. Here, an operation for reproducing an image and an audio signal normally recorded on the magnetic tape 31 will be described first, and then the first and second still images recorded by the method as shown in FIG. 4 will be reproduced. The operation at that time will be described.

First, normal reproduction will be described. When the microcomputer 34 receives a reproduction instruction from a button (not shown),
It instructs the tape drive circuit 44 and the reproduction signal processing circuit 37 to reproduce the information recorded on the magnetic tape 31. The reproduced image information is sent to the image multiplexing circuit 38, and the audio information is sent to the speaker 45 for reproduction.
AUX and AAUX system data are sent to the microcomputer 34. Here, since normal image reproduction is performed, the microcomputer 34 only controls the tape drive circuit 44 and the image multiplexing circuit 38. In the image multiplexing circuit 38,
Since data is not sent from the microcomputer 34 to the drawing information decoding unit 51, the image signal sent from the reproduction signal processing circuit 37 is sent to the frame writing unit 54 by the memory writing control unit 54.
, And the frame memory reading unit 55 reads the data as it is, and the display data multiplexing unit 57 sends the data to the display circuit 40 as it is, whereby the reproduced image is displayed on the liquid crystal panel 41.

Next, the operation of reproducing the first still image and the second still image recorded by the method as shown in FIG. 4 will be described. The user sets in advance whether to view the multiplexed image (second still image) of the handwritten image or the original image (first still image) in which the handwritten image is not multiplexed,
It is assumed that the microcomputer 34 stores one of them. When the microcomputer 34 finds a handwritten image pack during reproduction, the microcomputer 34 controls the tape drive circuit 44 to perform an operation of displaying only an image desired by the user.

FIG. 7 is a flowchart of the operation during normal reproduction.
Shown in After the reproduction is started, in step 100, the microcomputer 34 detects whether or not the sub-code data sent from the reproduction signal processing circuit 37 includes a maker code pack. When the maker code 62 is 02h, the handwriting in which the pack header 71 is F1h is performed. When an image pack is detected, the process proceeds to step 101. If the handwritten image pack cannot be detected, the reproduction operation is continued.

In step 101, the still image to be displayed set by the user is checked, and if it is the second still image, the reproduction is continued as it is, so that the second still image is displayed. This is because the first still image records only about 15 frames, and since the first still image is the original image, the second still image is naturally displayed to the user's eyes. For this reason, the processing can be simplified.

On the other hand, if the user has set the first still image, the first still image is reproduced for several frames in step 102, and thereafter, the memory writing control unit 54 is instructed to record the first still image in the frame memory 53. The display is fixed with the still image of No. 1. The reproduction is continued without any instruction to the tape drive circuit 44, and the audio is output.
At that time, the number of frames of the second still image recorded in the handwritten image pack is stored, and in step 103, the number of frames from the start frame of the second still image (the frame next to the last frame recorded in the handwritten image pack) is changed. Counting starts, and here, when 150 frames have elapsed, step 10
In step 4, the frame writing unit 53 instructs the memory writing control unit 54 to release the fixed frame memory 53, and returns to the normal reproduction state.
As described above, a still image desired by the user can be output.

While the first embodiment of the present invention has been described above, the number of recording frames of the second frame is always set to, for example, 150 frames at the time of recording. The same function can be realized by counting. Also, the second
In the method of recording the bit 72 of the handwritten image pack with 1 set to 1 in the subcode area of the still image recording area, the end frame of the second frame can be found in step 103 at the time of reproduction. Can be realized.

Further, the handwritten image pack corresponding to the first still image used in the present embodiment only needs to be able to discriminate the recording start frame of the first still image and the recording start frame of the second still image. Of the recording area of the first still image,
A method of recording only in the start frame and the last frame may be used. Since the handwritten image pack for the above-mentioned second still image may be recorded so that the last frame of the second still image can be recognized, a method of recording only the last frame of the second still image is also possible. In this case, a handwritten image pack corresponding to the first still image may be recorded only in the start frame of the first still image.

(Embodiment 2) Next, a second embodiment of the present invention will be described. Although the basic configuration is the same as that of the first embodiment, the operation at the time of recording and the operation at the time of reproduction are different. Therefore, the operation centering on the microcomputer 34 will be described. Note that, similarly to the first embodiment, an image (original image) in which a handwritten image is not multiplexed is referred to as a first still image, and an image in which a handwritten image is multiplexed is referred to as a second still image.

At the time of recording, the microcomputer 34 instructs the recording data multiplexing unit 58 to store the handwritten image and the frame memory 5.
An image multiplexed with the image fixed to 3 is output to the recording signal processing circuit 39, and the recording is started by instructing the tape driving circuit 44. During the recording of the second still image, a handwritten image pack slightly different from that of the first embodiment is recorded in the subcode. The MAKER CODE pack is the same as that in the first embodiment, but the handwritten image pack in this embodiment is as shown in FIG. 8, and the pack header is F1.
h and bit 81 are 0 as in the recording area of the image in which the handwritten image is not multiplexed and 1 in the recording area of the multiplexed image as in FIG. Other areas are reserved areas and are filled with 1.

After the second still image has been recorded by an appropriate number of frames, the microcomputer 34 instructs the recording data multiplexing unit 58 again to output from the frame memory reading unit 55,
That is, only the first still image is output to the recording signal processing circuit 39. The first still image is 90 in this embodiment.
It is assumed that recording is performed with the frame fixed, and the recording ends. FIG. 9 is a schematic diagram of the recorded contents of the magnetic tape 31 recorded as described above.

When the first and second still images recorded in this way are reproduced, the user is made to select which image is to be output, similarly to the first embodiment. FIG. 10 shows a flowchart of the processing of the microcomputer 34 during reproduction.

After the start of reproduction, a handwritten image pack is searched for in step 110 as in the first embodiment. If detected, the process is divided according to the still image to be displayed in step 111. If the second still image is to be displayed, step 112
After reproducing several frames of the second still image, the memory writing control unit 54 is instructed to fix the frame memory 53. While displaying 90 frames from the start frame of the first still image in step 113 while keeping the display as it is (sound is output in the same manner as in the first embodiment), step 1
At 14, the fixing of the frame memory 53 is released, and the normal reproduction is resumed. As in the first embodiment, the start frame of the first still image is a frame in which a frame in which no handwritten image pack is recorded is detected for the first time after the detection of the handwritten image pack.

If the first still image is to be displayed in step 111, the memory writing control unit 54 is instructed in step 115, and the frame immediately before the second still image recorded in the frame memory 53 is recorded. (Since the frame memory 53 can hold two images), the frame memory 53 is fixed. Step 116
If it is detected that the recording area of the second still image has ended by the end of the area in which the handwritten image pack is recorded in step 117, the process proceeds to step 117 where the second still image is recorded on the surface of the frame memory 53 where the second still image is recorded. The reproduced first still image is written, and the state returns to the normal reproduction state. Note that, as in the first embodiment, sound is output even while the display is fixed in the frame immediately before the second still image. If the frame immediately before the second still image is an unrecorded portion, the display is fixed in a blue-back state while the recording area of the second still image is being reproduced.

Thus, as in the first embodiment, only the still image desired by the user can be viewed. Here, as in the first embodiment, even if the first still image is recorded first, the first and second still images are processed by the microcomputer 34.
Can be reproduced without any problem if the still image of the first still image is replaced.
Even if a handwritten image pack in which is set to 0 is recorded, there is no problem because the end point of the first still image can be detected. In that case, even if the recording order of the first still image and the second still image is reversed, it is still possible to reproduce the image without any problem.

Further, similarly to the first embodiment, the handwritten image pack only needs to know the start position of the second still image and the start position of the first still image. Even if the recording method is such that recording is performed only on the frame, it is possible to detect them at the time of reproduction and determine the respective top frames.

(Embodiment 3) Next, a third embodiment of the present invention will be described. DVC of the third embodiment
The main configuration is the same as that of the first and second embodiments, but the processing of the microcomputer 34 is different, and the operation of multiplexing and recording the handwritten image and the original image obtained from the camera 35 and the operation at the time of reproduction are The second embodiment is the same as the first embodiment except that a second still image in which a handwritten image is multiplexed with a first still image as an original image can be erased and rewritten. Therefore, the DVC according to the present embodiment has an erasing head (not shown), and can erase information on the magnetic tape 31 in conjunction with the recording operation.

First, the second still image erasing operation will be described. When erasing the second still image, the user sends an instruction to the microcomputer 34 through a button (not shown) to drive the magnetic tape 31 so that the first still image recorded immediately before the second still image to be erased is recorded. The magnetic tape 31 is stopped at the position of the image. Of course, automatically the microcomputer 34
May have a function of searching for and stopping a handwritten image pack. Subsequently, when the user gives an erasure request to the microcomputer 34, the microcomputer 34 starts the erasing operation of the second still image.

The microcomputer 34 starts reproduction of the first still image, instructs the memory writing control unit 54 to hold the first still image in the frame memory 53, and reads the frame memory in the recording data multiplexing unit 58. The setting is made so that only the signal from the unit 55 is output. Subsequently, overwrite recording of the first still image held by the frame memory 53 is started from the start frame of the first still image, and the number of frames obtained by adding 15 frames to the number of frames described in the handwritten image pack is started. Overwrite recording is performed and recording is completed. The handwritten image pack written in the subcode is also overwritten and deleted.
FIG. 11 shows the erase result. The hatched portion is the portion changed by the erasing operation.

By such an operation, the recorded handwritten image of the second still image can be erased. However, instead of overwriting the second still image with the first still image, a new still image is newly written. By overwriting the third still image created by multiplexing another handwritten image drawn on the touch panel 42 by the recording data multiplexing unit 58, the handwritten image can be changed. FIG. 12 shows the result of the change. Also in this case, the hatched portion is the portion changed by the rewriting operation. The above is the description of the third embodiment of the present invention.

Although the touch panel and the decoding circuit are used as the title image input means in the above embodiment, a device for inputting a handwritten image from outside such as a tablet may be used, or a keyboard or pointing device may be used. A device such as a titler that inputs a title character or an image by giving character information with a device or the like may be used.

[0092]

As is apparent from the above description, the present invention allows the original image and the image with the title to be selectively viewed even when a still image in which title images are multiplexed is recorded. Since it is possible to delete or change the recorded title image, there is an effect that, even though the title is recorded in a multiplexed manner with the video information, it is possible to start over even if the recording of the title fails. .
