BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camcorder, and more particularly, to an apparatus and method for inputting and displaying a title using a liquid crystal display device of a liquid crystal camcorder.

The EVF (Eye View Finder) camcorder, which is currently dominated, uses the function of the title using super impose or OSD (On Screen Display) to celebrate the shooting screen.

First, the super impose function is a function of drawing and storing contents to be input on a separate paper, etc., and storing them, and mixing the stored patterns at the moment of capturing the screen. However, such a superimpose function has a complicated preparation process as described above.

Next, the OSD Title function allows you to select within 32 characters (two lines and 16 lines each line) on the OSD. This function does not have a big problem for input because the alphabet is 26 characters in total, but there is a problem that the display of characters is insufficient with the memory of OSD IC that cannot exceed more than 150 characters because the number of characters is too large. In addition, the OSD title function has a problem that it is impossible to change the display area with 16 characters for each of two lines on the screen.

Accordingly, an object of the present invention is to provide an apparatus and method for inputting a title by hand using a liquid crystal display device of a liquid crystal camcorder.

These days, as camcorders have evolved into liquid crystal camcorders, liquid crystal monitors have become much larger than EVF, and the application of liquid crystal control technology enables the input of electronic signals through liquid crystals. Accordingly, the present invention uses the input device such as an electronic pen (human body is also possible) by using such a technique to allow a user to input arbitrary letters and pictures through a liquid crystal monitor to record and reproduce them.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall block diagram of a camcorder applied to the present invention. The lens part 2, the processor part 4, and the auto part 6 correspond to a camera system. The signal processing unit 8, the memory unit 10, the deck unit 12, the SYSCON part 14, the functional unit 10, and the servo unit 18 correspond to a VCR system.

The lens unit 2 is composed of n pairs of magnification and focus lens, a zoom motor, a focus motor, and an IRIS motor. The processor unit 4 processes the image through the lens 2 with a CCD and outputs Y / C separation. The auto part 6 controls the lens part 2 and the processor part 4 while performing a serial interface with the sheath part 14.

The signal processing section 8 processes the Y / C signal and outputs it to the outside (liquid crystal monitor 20 or TV 22), or records information on a tape in the deck section 12. The memory 10 continuously measures and stores an electrical signal input from the liquid crystal monitor 10 under the control of the sheath cone unit 14. The function unit 16 is composed of a plurality of keys and outputs key data corresponding to a user's command to the ciscon unit 14. According to the present invention, the keys provided in the functional unit 16 are a free write program key and a free write display key. The servo unit 18 controls the drum motor, capstan motor, and loading motor under the control of the sheath cone unit 14.

The liquid crystal monitor 20 is usually used as a liquid crystal display device, but is used as a title input device as well as the present invention. Therefore, the liquid crystal monitor 20 converts a user's handbook into an electrical signal, outputs the signal to the signal processor 8, and displays a Y / C signal output from the signal processor 8. The TV 22 receives and displays the Y / C signal and the audio signal of the signal processor 8.

FIG. 2 is a block diagram illustrating a process in which data written on the liquid crystal monitor 20 is recorded in the memory unit 10.

Looking at the rate of the liquid crystal monitor 20 in detail, it has an aquatic screen size and the screen is divided into m × n lines and causes a charge change in the aquatic portion. It is preferable that the screen size of the liquid crystal monitor 20 is at least 5 inches or more so that it can be aquatic, and the m × n line is preferably 250 × 200 lines.

The operation of the present invention will now be described in more detail with reference to FIGS. 1 and 2.

First, the operation of inputting the title of the liquid crystal camcorder will be described. When the user presses the pre-light program key on the function unit 16, the sheath control 4 controls the signal processing unit 8 so that the "FREE WRITING INPUT MODE" is displayed on the LCD monitor 20 and the TV 22. . After that, the user writes the characters to the liquid crystal monitor 20. For example, the user can use the pen This will come to Suseo. Then, the received portion of the liquid crystal monitor 20 causes charge change. Accordingly, the signal processor 8 senses the change in charge by the aquatic unit at a unit time period under the control of the sheath cone 14 and outputs the corresponding position data FW1, FW2, FW3 .... In the present invention, the signal processor 14 corresponds to handwriting sensing means. The position data FW1, FW2, FW3 ... are composed of (m x n). For example, FW1 is configured in the form of (m1, n1), FW2 is (m2, n2), and FW3 is (m3, n3). The position data sensed by the signal processor 8 is stored in the memory unit 10 under the control of the ciscon unit 10. In this case, the ciscon unit 10 controls the position data when the handwriting of the character is continuously connected, and controls only the position data when the handwriting of the character is not continuously connected to the memory unit 10. Save to control. The location data stored in the memory unit 10 becomes the title of the liquid crystal camcorder.

After that, when the user presses the pre-write program key again, the ciscon unit 14 ends the title storing of the liquid crystal camcorder.

Next, an operation of displaying the title of the liquid crystal camcorder will be described. When the user presses the pre-light display key in the function unit 16, the sheath cone 4 controls the signal processing unit 8 so that "FREE WRITING DISPLAY MODE" is displayed on the LCD monitor 20 and the TV 22. . Then, the ciscon unit 14 reads the title of the liquid crystal camcorder stored in the memory unit 10 and outputs the title to the signal processing unit 8, and controls the signal processing unit 8 to display the liquid crystal on the current screen output from the processor unit 4. The titles of the camcorders are mixed and displayed on the screens of the liquid crystal monitor 20 and the TV 22. Accordingly, the title of the liquid crystal camcorder is displayed on the screens of the liquid crystal monitor 20 and the TV 22 together with the current screen.

Then, when the user presses the pre-light display key again, the ciscon unit 14 erases the displayed title and returns to the original screen.

As described above, the present invention has an advantage of inputting a title by handwriting and displaying it by using a liquid crystal display device of a liquid crystal camcorder.
