Abstract

PURPOSE:To readout a character indicating the condition of a recorded picture simply from the recorded picture by storing character data in a memory as a part of the picture together with the picture data and displaying the character data on a prescribed area of the picture. CONSTITUTION:A code converter/writer 7 writes character data stored in a character memory 2 in a specific area of a picture memory 1 by an ASCII code e.g. Thereby, a specific code storing area is prepared in the picture memory 1 and the code of the character data is stored in the specific area together with the picture data. Consequently, the characters obtained by developing the character data stored in the character memory 2 are superposed to the picture data stored in the picture memory 1 and the code of the character data and the superposed data are outputted from a video data adding part 4. The contents are displayed on the picture plane of a display device 5 as the data of the display output and recorded on a recorder 6.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is capable of recognizing character data from a displayed image by storing character data of characters to be superimposed on an image in a predetermined area of an image memory. The present invention relates to a character data storage processing method.

[Conventional technology]

FIG. 3 is a diagram showing an example of the configuration of a conventional display system,
1) is an image memory, 12 is a character memory, 13 is a character generator, 14 is a video data adder, 15 is a display device, and 16 is a recording device.

The display system shown in FIG. 3 is used, for example, when character data is displayed superimposed on image data obtained as a result of analysis by an analysis device or the like. That is, image data is stored in the image memory 1), and the conditions of the image data, such as center temperature, temperature range, zoom number, etc.
Character data such as comments are stored in character memory 12. Of these data, character data is developed into a display pattern by a character generator 13, and the display pattern developed here is added to the image data stored in the image memory 1) by a video data addition section 14. and displayed on the screen of the display device 15. The recording device 16 records (records) the data superimposed in this way.
R is used.

[Problem that the invention seeks to solve]

However, in the display system shown in FIG. 3, if the display output is recorded in the recording device 16 such as a VTR, and the image is later played back and written to the memory, the V
Although characters and images are recorded on the TR at the same time, it has been difficult to read the characters indicating the conditions of the image, for example. In other words, in order to read the characters that indicate the conditions of the image, it is necessary to recognize the image of the characters, and it is necessary to prepare a sophisticated system. Therefore, it was difficult to easily read the conditions of an image using a computer.The present invention is based on the above consideration, and it is possible to easily read characters indicating the conditions of the image from a recorded image. The purpose of the present invention is to provide a character data storage processing method that can be used.

[Means for solving problems]

To this end, the character data storage processing method of the present invention stores image data and character data in a memory and displays the image and characters in a superimposed manner. The character data is stored in memory along with the predetermined character data of the image.

It is characterized by displaying in the area.

[Effect]

In the character data storage processing method of the present invention, character data is displayed in a predetermined area of the image, so even if the image is recorded (recorded) and played back later,
When recognizing the characters displayed in the image, the character data can be read from the bit pattern in a predetermined area of the image without using a method that performs image recognition of the character. .

〔Example〕

Examples will be described below with reference to the drawings.

FIG. 1 is a diagram showing the configuration of one embodiment of a display system to which the present invention is applied, and FIG. 2 is a diagram for explaining encoding of character data.

In FIG. 1, 1 is an image memory, 2 is a character memory, 3 is a character generator, 4 is a video data adder, 5 is a display device, 6 is a recording device, 7 is a code conversion/writing device, 8 indicate playback devices, respectively.

The code conversion/writing device 7 converts the character data stored in the character memory 2 into ASCII code (American Standard Code for example).
r Infor IIlation Interchan
ge) to write to a specific area of the image memory 1. For this purpose, a specific code storage area is prepared in the image memory 1, and along with the image data, characters and
The data code is stored. Therefore, a character character obtained by expanding the character data stored in the character memory 2 is superimposed on the code of the image data and character data stored in the image memory 1, and is output from the video data adder 4. Ru. Then, this content is displayed on the screen of the display device 5 as display output data, and recorded in the recording device 6! (recorded).

For example, if the last bit of each horizontal line is allocated to the code storage area of the image memory 1 as shown in FIG.
This means that 32 character codes can be written using the I code. The example of bits 0 to 8 in FIG. 2 shows rJJ in hexadecimal ASCII I code. Therefore, when the code storage area is allocated in this way, the display output can be transferred to the VTR.
Record the image on a recording device 6 such as a computer, play the image later, and take notes.

When writing in the image, the characters superimposed on the image can be recognized by sequentially reading the last bit of each line one byte, that is, eight lines at a time.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, since display characters are coded and written into the image memory,
Even when recording the display output of an image on a VTR etc. and playing it back later, by reading a specific area of the recorded image,
Can recognize characters displayed in images. Therefore, there is no need to provide special means to record the displayed characters or read them after playback, and with a simple system configuration, the displayed characters in the image can be recognized even after recording and playback.
