2. Description of the Related Art Generally, a video recording device such as a camcorder has a built-in editing function. Here, the title editing function is, for example, when recording a video of an athletic meet as a camcorder, a character in the middle of the recording for later playback,
This means inserting a title, sentence pattern, design, etc. Since the title editing function built in the above-mentioned camcorder does not correspond to various users' demands, the necessity for improvement by this is increasing.

A conventional title editing function will be described with reference to FIG. First, at the time of title editing, a luminance signal Y of a title such as A is input to an input terminal IN through a camera of a camcorder (not shown). Here, the title A is a title created by the user for a predetermined purpose. The A / D converter 4 converts the luminance signal of the title A into digital data and serially outputs it through the gate array 6. The gate array 6 converts and outputs the digital data as parallel data of a predetermined bit under the control of the control unit 2. Therefore, under the control of the control unit 2, the parallel data is stored at the designated address of the storage unit 8.

In general, the storage section 8 is composed of a 64 Kbit RAM (random access memory) for storing a title A (256 × 256 pixels) for one screen.
On the other hand, when the title A is edited on the recording medium, the luminance signal Y of the camera is input to the mixer 10 through the input terminal IN. Subsequently, under the control of the control unit 20, the title data of the storage unit 8 passes through the gate array 6 and the
Input to 0. The mixer 10 mixes the data of the title A and the luminance signal of the camera and outputs the mixed data to the output terminal O.
Output to UT. Therefore, the title A of the output terminal OUT is
Is edited at the time of recording the actual video on the recording medium.

[0005]

The above-mentioned conventional title editing function has a disadvantage that the number of titles is limited due to the small capacity of the storage unit, so that a large number of titles cannot be edited. In addition, there is a problem that the title cannot be stored due to the operation function during the actual recording of the video. An object of the present invention is to provide a remote controller having a title editing function that can easily edit a title while recording it.
