Description

The present invention relates to a character editor and a Process for character editing which in a recording and Playback device such as a VCR and a camcorder can be used. Through the drawing editor and that Character editing methods can use different character signals used in image signals to mark characters on the recording medium by means of an integrated memory circuit (MIC) card.

Recording and playback devices such as VTR and camcorders increasingly common and are used by their users too used, for example, for a graduation, marriage or birthday scenes to record on a video tape.

However, the conventional recording and playback devices, no function on giving the user any information to deliver on the recorded images so that the User the title of the recorded event on the container write the video tape used for recording got to. Therefore, the known devices can meet the needs of users to display the corresponding images accordingly Titles with characters in the opening scene, similar to feature films, not meet.

In a generic character editor known from US 4999709 can in those recorded by a video camera Different titles can be displayed. The title data are stored in an addressable memory and are from this corresponding to those that can be generated by an address generator Address signal available. The title data is represented by a graphic image information on a poster, a poster or the like. This graphic information will  recorded by the video camera and stored in memory. For reading out and feeding the title data A switch can be operated to convert data into video signals. Additional switches are used for horizontal and vertical Scroll the title data relative to that recorded by the video camera Video signals. Finally, by pressing one further switch the color representation of the displayed Titles can be selected.

A disadvantage of the known character editor and the method for character editing is that the corresponding images, for example first be recorded on a video tape and then the correspondingly displayed title be recorded separately. This is followed by a crossfade function the simultaneous playback of video images and Titles. Therefore, images and titles must be played back relatively much time since the inclusion of these two are done separately got to.

The MIC card 20 supplies the image processor 10 with the stored sentences or symbol symbols in accordance with the control of the MICOM 30 , which drives the MIC card 20 in accordance with signals supplied by key signals from the keypad K or the receiving part 40 .

With regard to a remote control for transmitting a signal to the receiving part 40 , the remote control for the character editor 51 can additionally be prepared with a remote control 52 for a VTR, or a combined remote control 50 of the two remote controls 51 and 52 can be used.

The keys A, B, C, D and E of the remote control 51 for character editing according to FIG. 2A serve as operation keys, such as a color selection key, character size key or memory key.

The image processor 10 mixes the input image signal with a character signal supplied from the MIC card 20 . The image processor 10 is connected to a cathode ray tube (CRT) and a recording and storage part 60 for recording the image signal according to the control of a microprocessor 30 .

In Fig. 3 a flow chart is shown illustrating the Zeicheneditierverfahren the invention. The flowchart includes an operation mode decision process P1, a selection process P2, a movement process P3, a color change process P4, a size change process P5 and a storage process P6.

The procedure is described in detail below. First, the mode decision process checks P1  by a first decision step S1 whether the device in Editing mode is. Through the first decision step S1 the mode is checked and by a display step S2 are stored on the MIC card or Drawing symbols shown.

The selection process P2 selects the sentences or shown Character by a second decision step S3 to Check whether a character selection key has been pressed or not from.

Subsequently, an elimination step S4 becomes Eliminate unselected sentences and a Playback step S5 for playing selected sentences or characters performed by the character selection buttons.

The movement process P3 moves the characters or sentences through Moving a cursor using a third Decision step S6 to check whether a Cursor key was pressed, and one Character / sentence movement step S7 for moving sentences or Characters by pressing the cursor key.

The color change process P4 changes the color of the Character by a fourth decision step S8 Check whether a color selection button has been pressed and a color changing step S9 for changing the color of the Characters corresponding to pressing the color selection key.

The resizing process P5 resizes the Character by a fifth decision step S8 to Check whether a character change key has been pressed and a character changing step S11 for changing the Character size according to pressing the Character change key.  

Finally, the storage process P6 records the output signal of the image processor 10 on a recording medium and stores it thereon by a sixth decision step S12 for checking whether a memory key has been pressed and a storage step S13 for storing the output signal of the image processor 10 on the recording medium.

According to the character editor described and the method for character editing, if the user wants to edit characters on an image recorded on a recording and reproducing device, the MIG card 20 according to FIGS. 2C and 2D into the opening 21 of the Insert VTR or camcorders as shown in Fig. 2A and 2B. Then the MIC card 20 is connected to both the image processor 10 and the MICOM 30 . The MIC card 20 contains sentences or characters for various occasions, as shown in FIG. 2D, for example in Korean or English.

Consequently, the MIC card 20 serves as a word processor under the control of the MICOM 30 . After the MIG card 20 is connected to both the image processor 10 and the MICOM 30 , it is first checked in decision step 51 whether the user operates the MICOM 30 and the MIG card 20 in the edit mode by pressing the keypad K or the remote control 50 is set.

When the user sets the MICOM 30 and the MIC card 20 in the edit mode, the MICOM 30 feeds various sentences or characters to the image processor 10 that are stored in the MIC card 20 .

Subsequently, the image processor 10 synthesizes the sentence or character signal with an input image signal and supplies it to the CRT.

A representation according to FIG. 4A or 4B then appears on the CRT. FIG. 4A shows a representation on the CRT in which a MIC card was inserted into the recording and reproducing device for a graduation ceremony. FIG. 4B shows an illustration of a CRT when a MIC card for characters has been inserted into the recording and reproducing device.

If a number key has been pressed, the MICOM 30 carries out the elimination step S4 to eliminate all other sentence signals supplied to the image processor 10 from the MIC card 20 except for the selected sentence. If the key pressed is not a number key but a cursor key, the MICOM 30 carries out the display step S5 to display the character signal selected by the cursor.

The MICOM 30 then executes the third decision step S6 to check whether the cursor key has been pressed by the keypad K or the remote control 50 . When the cursor key has been pressed, the MICOM 30 performs the character and sentence movement step S7 to move the selected characters or sentences by moving the cursor on the CRT.

Then the MICOM 30 performs the fourth decision step S8 to check whether a color selection key has been pressed. If a color key has been pressed, the MICOM performs the color change step S9 to display the character or sentence with the color selected by the color selection key on the CRT.

Subsequently, the MICOM 30 performs the fifth decision step S10 to check whether a resize key has been pressed. If a resize key has been pressed, the MICOM 30 performs the resize step S11 to display the character or sentence with the size selected by the resize key on the CRT.

The MICOM 30 then carries out the sixth decision step S12 to check whether a memory key of the keypad K or the remote control 50 has been pressed. If a memory key was pressed, the MICOM 30 finally carries out the storage step S13 in order to record and store the output of the image processor 10 on a recording medium by means of the recording and storage part 60 .

Accordingly, the mixed signal of the image signal supplied to the image processor 10 and the character signal provided by the MIC card 20 is recorded and stored on a recording medium such as a video tape.

In summary, according to the invention, one on the MIC card saved sentence or characters in one recorded image signal according to the control of a  Keypad or remote control can be used, the MIC card, which different sets or symbols contains, with a conventional recording and Playback device is connected so that the user easily Can edit characters.
