Abstract

PURPOSE:To inform explanation to the operator when an operation is unknown and a method to meet a trouble by using a title insertion function in electronic video equipment. CONSTITUTION:The electronic video equipment is equipped with a ROM 10 in which character information and graphic information of an operation manual, etc.. are stored. every kind of sensor 17, a help switch 19, a change-over switch 11, and a system controller 16, and displays a video signal and a title signal by superimposing in an ordinary operation. When the trouble is detected by the operation of the help switch 19 or every kind of sensor, the system controller 16 switches the change-over switch 11, and displays the content of the ROM 10 selectively.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic image device having a title inserting function in a camcorder or the like.

[0002]

2. Description of the Related Art Almost all video tape recorders (VTRs) with a built-in camera which are currently on sale have a digital title function (for example, Japanese Patent Laid-Open No. 63-172).
577 publication). Basically, a video camera is used to shoot a subject, the dark part of the subject is cut out by a comparator, binarized, and stored in a static random access memory (SRAM) to superimpose the image currently being shot. And output it. In addition to this, there is also a product in which the manufacturer does not have to create each title by putting it in the memory beforehand. Recent camcorders have become multifunctional, and the operation tends to be complicated accordingly. Therefore, each company has adopted an auto lock button.

[0003]

However, in the method of using the auto-lock button for the multi-functionality of the conventional camcorder described above, setting the auto-lock button makes the operation simpler but leaves it to the machine. , There is a problem that you can not enjoy various variations. In addition, in case of a trouble, it is difficult to understand what should be done only by displaying the symbol. The present invention solves the above-mentioned conventional problems, and uses a title insertion function provided in a camcorder, and an electronic image device capable of notifying a user of an explanation when an operation is lost or a coping method for a failure. It is intended to provide.

[0004]

In order to achieve the above object, the present invention provides a title display when a button is pressed in a camera-integrated VTR or electronic still camera having a display device such as an electric viewfinder and a title display function. The circuit is used to display the character information and the graphic information such as the operation explanation stored in the memory in advance as needed by the operator.

[0005]

Therefore, according to the present invention, it is possible to know the detailed operation method without the instruction manual.

[0006]

1 shows the structure of a video camera (electronic image device) with a digital title function according to an embodiment of the present invention. In FIG. 1, 1 is a lens, 2 is a charge coupled device (CCD), 3 is a preamplifier, 4 is a process unit, 5 is a timing generator, 6 is a comparison circuit, 7 is a serial / parallel conversion unit, and 8 is a static random access memory ( (SRAM), 9 is an address counter, 10 is a ROM, 11 is a changeover switch, 12 is a parallel-serial converter, 13 is an encoder, 14 is a control pulse generator, 15 is an address counter, 16 is a system controller.
(Microcomputer), 17 are various sensors, 18 are various switches, and 19 is a help switch (HELP-SW). FIG. 2 is a flowchart of a help routine in the system controller (microcomputer) of the present invention. The function of the method of coping with the case where the operation of the present invention is lost or a failure occurs will be described with reference to FIG. 1 according to the flowchart of FIG. If you do not understand the operation, press the help switch 19 (Fig. 1)
The system controller 16 enters a help routine. In this case, it is judged that there is no trouble (condensation, etc.) because the help switch 19 is pressed, and the explanation corresponding to the latest mode is read out from the ROM 10 and displayed (S ₁ , S ₂ , S ₃ ,
S ₄ ). If the display is not intended, the help switch 19 is pressed again to increment the read address of the ROM 10 and display the following explanation (S ₆ ,
S ₃ , S ₄ ). Repeat this until the purpose is explained, and when the purpose is explained, for example, help switch 19 for a certain period of time.
The system controller 16 is configured so that it is determined to be the intended one unless is pressed, and this routine is ended. Also, it is configured so that this routine can be entered even if there is a problem. For example, when the dew condensation camcorder ensued, the signal from the "Dewsensor" sensor 17 is sent to the system controller 16, configured to display a treatment method (S ₇₎ terminates accordingly. In addition, switch (S
W) 11 is on the normal SRAM 8 side, and the encoder 13 superimposes the video signal and the binary signal of the title. If the help switch 19 is pressed or if there is something wrong with the signals from the various sensors 17,
Switch by control signal from system controller 16
The (SW) 11 is tilted to the ROM 10 side, and the information in the ROM 10 is sent to the encoder 13 for display.

[0007]

As is apparent from the above-described embodiments, the present invention has the effect that the operation of the help switch allows the user to understand the detailed operation method without carrying an instruction manual, and anyone can enjoy advanced photography. In addition, when a trouble occurs, the contents of the trouble and the treatment method are displayed based on the information from each sensor.
