FIG. 2 is a diagram for explaining the operation of the video signal recording / reproducing apparatus according to the first aspect of the present invention. Input medium 1
If the input surface is opaque, print the input guide on a sheet of a material and thickness that does not interfere with the detection of coordinates, and use this sheet by stacking it on the input surface. When the input surface of the input medium 1 is transparent, the input guide is printed on a sheet of a material that does not hinder the detection of coordinates, and this sheet is laid below the transparent input surface. Alternatively, a display device such as a CRT, LCD or EL may be laid under the transparent input surface. In FIG. 2, for example, the input surface is 1
With an accuracy of 024 × 1024 and the origin at the lower left, the coordinates of the four corners of the “record” area are: lower left corner: (X1, Y1) = (400,800) upper left corner: (X1, Y2) = ( 400,1000) Lower right corner: (X2, Y1) = (623,800) Upper right corner: (X2, Y2) = (623,1000). The coordinates of the four corners of the "playback" area are as follows: lower left corner: (X1, Y1) = (400,550) upper left corner: (X1, Y2) = (400,750) lower right corner: (X2, Y1) = (623,623) 550) Upper right corner: (X2, Y2) = (623,750). The coordinates of the four corners of the “stop” area are as follows: lower left corner: (X1, Y1) = (400,300) upper left corner: (X1, Y2) = (400,500) lower right corner: (X2, Y1) = (623, 300) Upper right corner: (X2, Y2) = (623,500). The coordinates of the four corners of the “pause” area are as follows: lower left corner: (X1, Y1) = (400,50) upper left corner: (X1, Y2) = (400,250) lower right corner: (X2, Y1) = (623 , 50) Upper right corner: (X2, Y2) = (623,250). The coordinates of the four corners of the "rewind" area are as follows: lower left corner: (X1, Y1) = (100,550) upper left corner: (X1, Y2) = (100,750) lower right corner: (X2, Y1) = (350 , 550) Upper right corner: (X2, Y2) = (350, 750).

Here, when a predetermined area on the input surface as shown in FIG. 2 is contacted, the input medium 1 detects the coordinate value at that time and supplies it to the area judging circuit 2. It is assumed that the area determination circuit 2 sequentially executes the operation of the conditional expression indicating the range of each area and selects the function assigned to the area of the range indicated by the conditional expression such that the operation result is true. to decide. The operation of the area determination circuit 2 when the input surface is as shown in FIG. 2 will be described with reference to FIG. Coordinates are input from the input medium 1 (X, Y)
(201). When X is 400 or more and 623 or less and Y is 800 or more and 1000 or less (202), the "record" area is selected (212). Otherwise, X
Is 400 or more and 623 or less, and Y is 550 or more and 750
When it is (203), select the "playback" area (2
13). Otherwise, when X is 400 or more and 623 or less and Y is 300 or more and 500 or less (20
4) Select the "stop" area (214). Otherwise, when X is 400 or more and 623 or less and Y is 50 or more and 250 or less (205), the "temporary stop" area is selected (215). Otherwise, when X is 100 or more and 350 or less and Y is 550 or more and 750 or less (206), the "rewind" area is selected (216).
Otherwise, when X is 673 or more and 923 or less and Y is 550 or more and 750 or less (207), the "fast-forward" area is selected (217). Otherwise, it waits for input on the input medium 1. If there is a corresponding area on the way, the selected area is output (218).

Here, for example, when the user wants to "play" the VTR, when the user touches the playback area of the input surface of the input medium 1 with the pen, the input medium 1 receives the coordinate value of the point touched by the pen, for example (500, 600) is supplied to the area determination circuit 2.
The area determination circuit 2 operates according to the above procedure. Now X = 500
Satisfies 400 ≤ X ≤ 623 and Y = 600 satisfies 550 ≤ Y ≤ 750. Therefore, it is determined whether (400 ≤ X ≤ 623) AND (550 ≤ Y ≤ 750) holds. In step 203, the timer microcomputer 3 is supplied with a code indicating that the area is judged to be true and the "playback" area is selected. The timer microcomputer 3 sends a video signal recording / playback unit 5 a signal for playback.
Is supplied to a system microcomputer (not shown), which sends a control signal necessary for reproducing a video signal from the magnetic tape to reproduce the VTR. Here, the operation in the case of reproducing the VTR has been described, but the same procedure can be used by the user for recording, stopping, pausing, rewinding, and fast forwarding. Operation can be executed.

FIG. 4 is a diagram for explaining the operation of the video signal recording / reproducing apparatus according to the first embodiment of the present invention.
The coordinate values supplied from the input medium 1 are supplied as coordinates having an accuracy of 1024 × 1024, with the input surface being, for example, the origin at the lower left. The processing circuit 7 performs a process of converting the coordinate value supplied from the input medium 1 into a signal form for displaying on the display device, and outputs from the writing image output terminal 8. For example,
Like an NTSC standard signal, frame frequency: about 30 [Hz], field frequency: about 60 [Hz], number of scanning lines: 525, aspect ratio capable of displaying 2: 1 interlaced scanning signal is 4: 3. The description will be made assuming that an output signal from the handwritten image output terminal 8 is input to the display device of FIG. Since the number of scanning lines of the display device is 525, the effective pixels are 480 vertical pixels and the aspect ratio is 4: 3 in consideration of the portion actually visible on the screen excluding the vertical blanking period. 6 because it is
Consider the case of 40 pixels. The horizontal coordinate of the input medium 1 is X (X = 0 to 1023), and the vertical coordinate is Y (Y =
0-1023), the horizontal coordinate of the display device: x
(X = 0 to 639), vertical coordinate: y (y = 0 to 47)
9), the horizontal coordinate of the display device: x is x = (639/1023) · X The vertical coordinate of the display device: y is y = (479/1023) · Y The following is rounded off to the coordinates (x, y) of the display device. The 640 × 480 image obtained here is scanned as an effective image area to form a video signal for displaying the image on the display device.

The input medium 1 sequentially supplies the coordinates of the contact of the pen to the processing circuit 7 at a constant cycle, and at the same time supplies the information of pen up and pen down. Alternatively, each time the input by the pen is changed, the coordinates of the change point, for example, the point at which the writing locus is bent are sequentially supplied, and at the same time, the information of pen up and pen down is also supplied. In the pen-up state, coordinate information is not supplied because the pen is not in contact with the display surface. Therefore, the entire display device is displayed in one predetermined background color (for example, black). The coordinates obtained at the same time as the pen-down information are converted into coordinates corresponding to the display device, and only the pixel in question is displayed on the display device in a display color (for example, white) different from the background color. When the pen-down information is obtained after the pen-up information is obtained immediately before, only that pixel is displayed. When the pen-down information is obtained subsequently to the pen-down information, all the pixels existing at the position connecting the currently displayed pixel and the previously displayed pixel are displayed in the display color. The operation of connecting pixels is performed by primary interpolation, secondary interpolation, or the like. If the video signal to be supplied to the display device is formed according to such a rule, the writing or drawing process of a character or the like or the drawing operation of a graphic or the like is performed on the input surface of the input medium 1 at almost the same time. It is displayed as if written or drawn on the display surface of the display device.

The operation of the processing circuit 7 when the input surface is as shown in FIG. 4 will be described with reference to FIG. FIG. 5 is a flow chart for explaining the operation of the processing circuit of the video signal recording / reproducing apparatus according to the first embodiment of the invention. First, the coordinates (X, Y) input from the input medium 1 are obtained (301). The pen information input at the same time is obtained (302). If the current pen information is not pen down (303), that is, if it is pen up, the process is stopped (310) until the next coordinate and pen information is input. When the current pen information is pen down (303), the coordinates of the input surface are converted into the coordinates of the display surface (304). When the stored pen information input one time before the pen information input this time is a pen down (305), the coordinate between the current input and the stored coordinate input one time before is set. An image interpolated for display is formed on the image memory (306). If the stored pen information that was input one time before the pen information that was input this time is not pen down (305), that is, if it is pen up, the image that displays the coordinates input this time is displayed in the image memory. Form (307). The coordinates input this time are stored for the next processing (308). The pen information input this time is stored for the next processing (30
9). It returns to the beginning of the process and waits for the next coordinate input and pen information input.

At the same time as processing the coordinates supplied from the input medium 1 by the processing procedure described with reference to FIG. 5 above, independently of the above processing, 306 in the flowchart of FIG.
If the image formed in the image memory in step 1 or step 307 is input to a display device to which a standard signal of the NTSC system is input, the frame frequency:
About 30 [Hz], field frequency: about 60 [Hz],
The number of scanning lines: 525, the signal written in the image memory is read so as to be a 2: 1 interlaced scan, processed so as to be a standard signal of the NTSC system, and output from the writing image output terminal. If the output is processed so as to be a signal of the same system as the system of the signal recorded / reproduced by the video signal recording / reproducing unit 5, it is switched by a switching circuit or the like and outputted from the video signal output terminal 6. May be.

Further, it has been explained that only the pixel obtained by converting the coordinate point at which the contact detected by the writing operation or the drawing operation is detected and the interpolated pixel are displayed in the display color different from the background color. It is also possible to make the writing locus by the writing operation or the drawing operation a predetermined thickness by simultaneously displaying a predetermined number of pixels positioned in a square shape in all directions. Further, it may be set in advance to a predetermined thickness, but it is also possible to provide some thickness options so that the user can select the thickness according to the purpose of use and the like at the time of use. Good.

In addition, the background color has been described as black and the display color as white for displaying the coordinate points obtained by the writing operation or the drawing operation. It is also possible to perform display with a predetermined display color and a predetermined background color by being configured to also perform color signal processing for chroma encoding from the RGB signals distributed to each. The display color and background color may be set in advance, but some color options are provided so that the user can make a selection according to the purpose of use at the time of use. May be.

Further, although the background color and the display color have been described as different colors in order to convert and display the coordinate points obtained by the writing operation or the drawing operation, it is already written with the display color different from the background color. When the writing or drawing operation is performed in the same display color as the background color when the writing or drawing operation is performed (this state corresponds to the writing operation with the "pencil"). It is possible to obtain a function corresponding to "eraser" for erasing the writing locus by the pixel group displayed by. In addition, the user may select whether the writing operation or the drawing operation is performed as “pencil” or “eraser” according to the purpose of use and the like at the time of use. Also, the size of the erased area (the size of the "eraser") can be set to a predetermined size in the same way as the thickness of the "pencil" above, or some size options can be provided to allow the user to May be configured to be selected according to the purpose of use and the like at the time of use.

In the above embodiments, the signal input to the display device is the NTSC system signal.
The same operation and similar effects can be obtained if processing is performed in the same manner regardless of the method, SECAM method, or any method. Also, although the aspect ratio was explained as 4: 3,
The same applies to 16: 9 and any aspect ratio. Although the number of scanning lines is 525, the number of scanning lines is 625 or 1125.
The same applies to 50 lines, 1250 lines, and any number of scanning lines. Further, although the description has been made with respect to the 2: 1 interlace, the same applies to non-interlace type and any scanning type.

As a result, the writing locus written or drawn by the pen on the input surface of the input medium 1 is sequentially displayed on the display device according to the writing operation, and actually the coordinates are supplied from the input medium 1 to the processing circuit 7 and displayed on the display device 27. Even though the signal is displayed in the form of a signal for writing, the writing operation can be performed as if the user were actually writing on paper with a pencil.

The created image is written in the storage circuit 9. In addition, the storage circuit 9 is operated by a user operating an image restoration button (not shown) or by touching an image restoration area provided in a part of the input medium 1 and determining by the area determination circuit 2 that the image restoration is selected. The stored image is read from. When the storage circuit 9 has a capacity capable of storing a plurality of images, a number for specifying which of the plurality of images may be designated when requesting image storage or image restoration.

For example, the usage pattern of the above embodiment will be described by taking the memo function as an example. The user writes a message on the input medium 1. As for the image on which the message displayed on the display device is written with the message of the content desired to be left, the image is stored in the storage circuit 9 by operating the image storage button or the like. Next, when viewing the stored message, the image is read from the storage circuit 9 and displayed on the display device by operating the image return button or the like. If this is a memo about the use of the VTR, if the stored message is displayed every time when the power of the VTR is turned on, the message can be viewed whenever the user wants to use the VTR.

That is, even if pen-up and pen-down are performed in the middle of the coordinate value series for one character, the coordinate value series is treated as one coordinate value series without being divided. Next, the sample points are reset so that the number of sample points forming the writing locus is constant for all input characters. The re-sampling of the sample points is performed by calculating the total length of the writing trajectories by summing the distances between the sampling points, and dividing the writing trajectory length by a predetermined number of sampling points to obtain the average distance between the sampling points. Then, sample points for each average distance are sequentially calculated from the starting point of the writing locus, and the sampled points are resampled to obtain a coordinate value series. Next, considering the input plane as a complex plane, the vector between each sample point is divided by the average distance to obtain only the phase component. The comparison circuit 1 uses the transform coefficient obtained by performing the discrete Fourier transform of this phase component as the feature of the written character.
Supply to 5. All of the conversion coefficients may be used as the feature amount for the recognition operation, but the calculation time may be shortened by excluding the higher-order components as long as the recognition rate is not reduced.

The character dictionary storage circuit 16 is a storage circuit corresponding to a dictionary in which the characteristic amount of each character is stored in advance, and is searched in order from the comparison circuit. The feature amount of each character is extracted and stored in advance in the same procedure as the feature extracting operation of the feature extracting circuit 14. The comparison circuit 15 sequentially compares the input characteristic amount of the character with the characteristic amount of each character stored in the character dictionary storage circuit 16, and the characteristic amount input from the characteristic extraction circuit 14 and the character dictionary. The distances from the characteristic amount of each character stored in the storage circuit 16 are sequentially obtained and supplied to the identification circuit 17. Identification circuit 1
Reference numeral 7 determines a character in the character dictionary storage circuit 16 having the shortest distance between feature amounts as a recognized character, and interprets this recognized character as an interpreter circuit 1.
Supply to 8.

Composed.

The reserved recording information has a lot of information that can be expressed only by numbers, such as the date, start time, end time, channel, etc., and if the number of character types is at most 10 types, the circuit scale of the recognition unit will be considered. It is also preferable in terms of recognition speed.
When the target character type of character recognition is limited to numbers, the date, the start time, the end time, and the channel can be expressed only by the numbers, and therefore no problem occurs. However, since the recording mode cannot be expressed by numbers, "1.SP mode, 2.EP mode" is displayed and the numbers "1" and "2" assigned to each are written in the entry box. . Further, it may be configured such that areas labeled "SP mode" and "EP mode" are provided and the recording mode is selected by designating these areas.

If the reservation information is not logically consistent, the reservation information is not supplied to the timer microcomputer 3 and a message or the like prompting the user to re-enter the item for which the logical consistency is not obtained is displayed.

[0116] For example, a VTR that can accept reservations up to one month in advance will take place on February 4, "30th, 20:00.
When the reservation information of "0 to 21:00, 6 channels, SP mode" is input to the input medium, the reservation operation is performed on February 4, so the date 30th is interpreted as February 30th. However, since the date of February 30 does not exist, the reservation information is not accepted and the re-input is urged. In this way, the logic determination circuit 22 stores information such as date, time, channel, etc. existing in advance, and determines whether or not the inputted reservation information is included therein.
