Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Utilization Valve IP) The present invention relates to a recording reservation device, and particularly to a recording reservation device suitable for home-use magnetic recording and reproducing devices.

(Prior Art) Conventionally, video tape recorders and the like have been able to automatically record a plurality of desired programs at a predetermined time slot by making a recording reservation.

In such recording reservation, the user sets the reservation number, recording channel, date, start time, end time, recording speed, etc. using an input device each time a reservation is necessary. As described above, since the recording reservation procedure requires several types of settings, the operation is relatively complicated and input errors are likely to occur.

Therefore, some conventional recording reservation devices use barcodes to enable recording reservations with simple operations and to reduce the occurrence of input errors.

Figure 5 shows a reservation sheet using such a barcode7.
1 is an explanatory diagram in which barcodes are applied to recording reservations. In addition, in FIG. 5, for simplification of the drawing, for example,
Regarding dates, only barcodes corresponding to days 1 to 7 are displayed. Actually, barcodes corresponding to days 1 to 31 are set. In addition, on the reservation sheet there is a barcode (
(not shown) are also displayed.

Barcodes are defined in JISXO501 and express information using a pattern of white bars and black bars. Note that the white bar indicates 'O' and the black bar indicates '1'. The user uses a barcode reader to read the barcode at a desired position on the barcode reservation sheet shown in FIG. That is, first, use a barcode reader to trace the barcode corresponding to the desired recording channel, and then use the barcode reader to trace the barcode corresponding to the desired day, start time, and end time. Trace it. In this way, the recording reservation operation is simplified by tracing the reservation sheet with a bar code reader instead of relying on key operations on the input device.

By the way, as described above, barcodes indicate information using a pattern of white and black bars, and users cannot easily create a reservation sheet using barcodes.

Therefore, when making a recording reservation, there is a problem in that a commercially available reservation sheet must be prepared. Also,
The barcode may include, for example, 1 to 12 recording channels,
The dates 1 to 31, the start and end times of 24 hours, etc. are set in detail, and many barcodes are displayed above the reservation sheets 1 to 31. Therefore, there is a problem in that it is relatively difficult to search for a desired barcode. Another problem was that the user could not know the content of the information by looking at the barcode.

(Problems to be Solved by the Invention) As described above, in the conventional recording reservation device described above,
It is necessary to prepare a reservation sheet using commercially available barcodes, and it is relatively difficult to search for a desired barcode from a large number of barcodes.Furthermore, there are problems in that the contents of the recording reservation are unclear. there were.

The present invention has been made in view of such problems, and includes:
User's handwriting, recording channel, date, etc.
It is an object of the present invention to provide a recording reservation device that can schedule recording by setting a start time, an end time, etc.

[Structure of the Invention] (Means for Solving the Problems) The recording reservation device according to the present invention is capable of sheath-slipping an input sheet into one, such as an input sheet for recording reservation in which a plurality of entry fields of a predetermined size are provided. By doing this, data based on the characters entered in the entry field is output.Then, a recognition dictionary memory that stores feature amounts for a plurality of characters and data from the image scanner are used to output data based on the characters entered in the entry field. A feature amount extraction means extracts the feature amount of the character entered in the column, and a feature amount outputted by this feature amount extraction means is compared with the feature amount stored in the recognition dictionary memory, and the feature amount written in the entry column is compared. The apparatus is equipped with a recognition means for recognizing characters, and a recording means for performing recording based on a recording reservation determined from the characters recognized by the recognition means.

(Operation) In the present invention, the characters written in the entry field are read by the image scanner 17. The feature amount extraction means extracts the feature amount of the characters written in the entry field based on the data from the image scanner. The recognition means compares the feature amount from the feature amount extraction means with the feature amount for each character stored in advance in the recognition dictionary memory, and recognizes the character written in the entry field. For example, the recording channel, date, start time, end time, etc. are entered in the entry fields, and the recognition means grasps the contents of the recording reservation by recognizing the characters written in each entry field. can do. In this way, the recording means can record a desired channel at a time period desired by the user.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings. FIG. 1 is a block diagram showing an embodiment of a recording reservation device according to the present invention.

Image scanner 1 has red light emitting diode 2 and mirror 3
, a condensing lens 4, and a linear image sensor 5, and is configured to read characters, numbers, etc. written on an input sheet 16, which will be described later. The reading width of the image scanner 1 is 64 mm, and the resolution is 8 dora 1~
/mm. That is, the reading width direction is divided into 512 dots.

Further, data for 512 dots (one line in the reading width direction) is output every time the sensor moves 0.125 mm in the operating direction. Therefore, the vertical and horizontal resolutions of the image scan Iys1 are both 8 dots/mm
It is. The image scanner 1 converts information such as characters and numbers into serial data, and connects it to the cable 6 and connector 7.
The signal is output to the timer recording circuit 8 via.

The timer recording circuit 8 is a serial-parallel conversion circuit 9, C.
R'T controller 1 to roller 10, data memory 11,
・Time count block 12, microcomputer 1
3. It is composed of a character/number recognition dictionary memory 14 and a recording circuit block 15. The serial-parallel conversion circuit 9 converts serial data input through the connector 7 into 8-bit parallel data and outputs it to the CRT controller 10. The CRT controller 10 transfers 8-bit parallel data to the data memory 11.
At the same time, the information is read out and applied to the micro combi coater 13. Further, the CRT controller 10 performs display control based on data stored in the data memory 11, and displays the contents of the recording reservation on a display screen (not shown).

The microcomputer 13 reads the data from the data memory 11 via the CRT controller 10 and compares the read data with the contents of the character/number recognition dictionary memory 14 to determine the characteristics of the handwritten characters written on the input sheet 16. Extract the amount and determine the recording channel, date, start time, end time, etc. The character/number recognition dictionary memory 4 stores features such as predetermined characters and numbers. The date/time count block 12 outputs data indicating the date and time to the microcomputer 3 by counting a predetermined clock. The recording circuit block 15 performs recording based on instructions from the micro combi coater 13.

FIG. 2 is a plan view without showing the handwriting input sheet 16.

The handwritten input sheet 16 includes a channel, a channel, and a
Characters such as CH1 date, start time, start minute, end time, end minute, and up are written in advance. Two 1 cm square squares 7 are provided for each of these items. The rectangular character ``Ji7'' is written in black ink, for example, and the other characters are written in red to prevent them from being read by the image screen. The user is supposed to write a desired number, etc. into this rectangular box 17.

Next, the operation of the recording reservation device configured as described above will be explained with reference to FIGS. 3 and 4.

The user writes the numbers O through 9 in the rectangular box 17 of the handwriting input sheet 16 with a pencil, pen, or the like. Next, the image scanner 1 is operated by hand to trace the area 117. The emitted light from the red light emitting diode 2 is reflected by the input sheet 16, and the reflected light enters the linear image sensor 5 via the mirror 3 and the condensing lens 4. The linear image sensor 5 photoelectrically converts incident light and outputs serial data. Since the resolution of the image scanner 1 is 8 dots/mm, the area within 17 is first divided into 80 x 80 dots, and each dot is either black (the area where the pen has passed) or white (the area where the pen has not passed). It is determined whether This J: Sea urchin, input sea 1 ~ with image scanner 1
By scanning 16, data including a plurality of 80×80 pieces of data, each with 11↓ added to the number in 17, is provided to the timer recording circuit 8.

Data input via the connector 7 is converted into 8-bit parallel data by the serial-parallel conversion circuit 9 and stored in the data memory 11.

The microcomputer 13 first performs line width enhancement processing on this data. For example, if the data of a predetermined dot is data indicating black, the data corresponding to two dots on the top, bottom, left and right of this dot are also converted to data indicating black. This increases the width of the lines of handwritten characters on both sides, and reduces erroneous recognition due to blurred characters and input rotation.

Next, the microcomputer 13 indicates the rectangular square 17 out of the data stored in the data memory 11 in order to grasp the positional relationship of the written number with respect to the square 17 and extract the characteristics of the number. Discover data. The data in box 17 can be detected from the fact that about 80 dots indicating black are continuous in the vertical and horizontal directions.

Next, is the microcomputer 13? Extraction between features is performed for numbers in 1-11.

FIG. 3 is an explanatory diagram for explaining a method for extracting features. In addition, in Figure 3, for convenience of explanation - 12, square 17
The inside is divided into 16x16 dots. Further, the numbers entered by the user are indicated by diagonal lines, and the dots indicated by the diagonal lines are called black dots.

First, the vertical range a and the horizontal range where characters are written are determined. In Figure 3, it is a-11 dot, and b
-10 dots. Further, the vertically central row of characters is Y8, and the horizontally central column is ×9. Note that if the center row or column is not determined to be one, the upper row or left column of the two is set as the center.

Next, the number of black dots is determined for each line Yl to Yl6. The results are shown in Table 1 below.

Table 1 Next, select two lines: the line with the largest number of dots and the line with the next largest number of dots. In Figure 3, lines Y3 and Y6
, Y7 have the same number of dots, so in this case, the line farthest from the center is selected.

That is, in FIG. 3, line Y13. Y3 is selected.

Next, find the distance from the center of these lines and get 10
It is normalized by multiplying it by 0 and further dividing by the vertical range a (-11 dots) to obtain feature M. d3. When calculating the distance to the center line, the distance from the center line to the small subscript line (the upper line in the figure) is set as a negative value.

Therefore, the distance (Y8-Y3) is -5 dots, the distance is 114
It (Yl3-Y8) is 5 dots, and the feature amount is expressed by the following equation (1).

In this way, the vertical feature fit(45, -45) is found. In the same way, feature quantities in the horizontal direction are also determined.

In the horizontal direction, the row with the largest number of dots is row X13. x5, and these columns are 4 dots and -4 dots apart from the center, respectively.
It's a dot. Also, since the horizontal range is 10, the feature amount is (/1.0.-40).

The character/number recognition dictionary memory 14 stores the maximum value T (Xmaxl, Xmax2. Ymax
l, Ymax2) are stored. The microcomputer 13 compares the feature interval (40, -40, 45, -45) obtained from the handwritten characters on the input sheet 16 with the maximum value T between each feature in the character/number recognition dictionary memory 14. Then, the character corresponding to the closest maximum value T is recognized as the character written by the user. In this way, the microcomputer 13 grasps the contents of the recording reservation specified by the user in the handwritten characters. The microcomputer 13 is C
An instruction is given to the RT controller 1o to display the contents of the recording reservation determined from the user's handwritten characters on the display screen 19 of the television receiver 18 as shown in FIG. 4J.

When the scheduled recording mode is set by the user's operation, the microcomputer 13 indicates that in the recording scheduled content shown in FIG. Then, an instruction is given to the recording circuit block 15 to start recording the 10 channels. Further, when the time indicated by the date/time column 1 head block 12 reaches 20:30 on the 18th, the recording is stopped.

As described above, in this embodiment, the recording reservation is made when the user enters the desired recording channel, recording time period, etc. on the handwritten input sheet 16. Therefore, the recording reservation setting work is easy, and input errors are extremely rare. Furthermore, it is easy to confirm the contents of the recording reservation. In addition, the handwritten cards 1 to 16 have multiple icm square pines 17 written on them, and the user can use similar handwritten cards.
1- can be easily created.

Note that the present invention is not limited to the above embodiments,
For example, it is clear that there is no need to limit the size of the input sheet 17 to 1 cm square.

[Effects of the Invention] As described above, according to the present invention, recording reservations can be made in a short time with extremely simple operations, and the contents of the recording reservations can be easily confirmed.

Another advantage is that recording reservations can be made using an input sheet created by the user.
