Operational Block Diagram Next, the operation of the video game device according to the present embodiment will be explained with reference to the block diagram of FIG. 4. FIG. 4 is a block diagram of the video game device which is in operation with the software cartridge loaded in the game device body 10. A control unit 100 controls drawing processing and sound making processing. A drawing control unit 102 controls a drawing processing unit 104 to draw a required picture, based on a position of the touch pen 28 relative to the picture book tablet 32. The drawing processing unit 104 writes line drawings in a buffer memory 120 through a buffer memory input/output unit 110. The drawing processing unit 104 controls writing required pictures in the buffer memory 120 and writing line drawings in the buffer memory 120, based on the position of the touch pen 28 relative to drawing tablet 24; and a movable body drawing unit 106 controls writing pictures of insects, animals, etc. in the buffer memory 120. The movable body drawing unit 106 draws pictures of movable bodies, such as insects, animals, etc., in a direction determined by a proceeding direction deciding unit 107. A sound making processing unit 108 conducts sound making processing, based on the position of the touch pen 28 relative to the drawing tablet 24 and color information from the buffer memory 120. A buffer memory input/output unit 110 writes color information in the buffer memory 120 in response to drawing control by the control unit 100 and reads color information from the buffer memory 120 and outputs the same to the control unit 100. In writing color information, a writing position: supplied by the control unit 100 is converted to an address of the buffer memory 120 by a coordinate conversion unit 112, and the color information commanded by the control unit 100 is written in the address by a color information writing unit 114. In reading color information, a reading position supplied by the control unit 100 is converted to an address of the buffer memory 120 by a coordinate conversion unit 116, and color information at the address of the buffer memory 120 is read by a color information reading unit 118 and outputs the same to the sound making processing unit 108 of the control unit 100. Image information is written in the video RAM 66 in images for each frame based on color information stored in the buffer memory 120 and is output to the monitor 90 through the image terminal 70. Audio information is output to the monitor 90 through the audio terminal 76 in audio signals outputted by the sound making processing unit 108. A First Example of the Video Game A first example of the video game of the video game device according to the present embodiment will be explained with reference to FIGS. 5 to 9. Basic Drawing Processing The drawing processing according to the first example will be explained with reference to FIGs. 5 to 8. FIG. 5 shows an example of pictures of the software cartridge 12 used in the drawing processing of the drawing processing according to the present example. When the touch pen 28 approaches a part of a picture in FIG. 5, the picture book tablet 32 detects the position of the picture book tablet 32 relative to the touch pen 28, and then the pen button 28a is pressed to input a drawing command corresponding to the position. On the left page 200 of the picture book tablet 32 of FIG. 5 there are arranged a canvas region 201, and sample picture regions 202, 203, 204. When the canvas region 201 is touched by the touch pen 28, a canvas on which pictures can be freely drawn is displayed on the monitor 90. When the touch pen 28 touches the sample picture regions 202, 203, 204, prescribed sample pictures are displayed on the monitor 90. On the right page 210 of the picture book tablet 32 of FIG. 5 there are arranged a pencil region 211, an eraser region 212, a net region 213, a conductor baton region 214 and a color command region 215. When the touch pen 28 touches the pencil region 211, the touch pen 28 functions as a pencil. Further a color of the pencil can be commanded by touching the touch pen 28 to the required color region in the color command region 215. When the touch pen 28 touches the eraser region 212, the touch pen 28 functions as a eraser. When the touch pen 28 touches the net region 213, the touch pen 28 functions as an insect net. When the touch pen 28 touches the conductor baton region 214, the touch pen 28 functions a conductor baton. The drawing processing will be explained with reference to the flow chart of FIG. 6. First, it is judged whether or not a sample picture has been selected by the touch pen 28 (step S10). When a game player contacts one of the sample regions 202, 203, 204 with the touch pen 28, the drawing control unit 102 controls the drawing processing unit 104 to draw the selected sample picture on the monitor 90 (step S11). FIG. 7 shows an example of the sample pictures. A grand piano is drawn. If none of the sample pictures has been selected, it is judged whether or not the canvas has been selected with the touch pen 28 (step S12). When the game player contacts the touch pen 28 to the canvas region 201, the drawing control unit 102 controls the drawing processing unit 102 to draw the canvas on the monitor 90 (step S13). FIG. 7 shows an example of the canvas picture. First the canvas without any picture is drawn. Then line drawings are drawn with the pencil on the monitor 90. First, a case in which line drawings are drawn on the canvas of FIG. 8 will be explained, but it is possible to draw line drawings on the sample picture of FIG. 7. First it is judged whether or not the pencil and a color have been selected by the touch pen 28 (step S14). When the touch pen 28 contacts the pencil region 211 and one of the color command region 215, the pencil 500 of a commanded color is displayed on the monitor 90. Then, it is judged whether or not the touch pen 28 is on the drawing tablet 24 (step S16). When the game player contacts the touch pen 28 to the drawing tablet 24, the drawing processing unit 104 outputs a position signal to the coordinate conversion unit 112, and a color signal is outputted to the color information writing unit 114. The coordinate conversion unit 112 converts the position signal to an address signal indicative of an address of the buffer memory 120. The color information writing unit 114 writes the color information indicated by the color signal in the converted address (step S17). When the game player moves the touch pen with the touch pen 28 in contact with the drawing tablet 24, as shown in FIG. 8, the pencil 500 moves on the monitor 90 in synchronization with the movement of the touch pen 28, and a line drawing of the selected color is drawn on the canvas. When the touch pen 28 contacts the color command region 215, the color of the pencil 500 is changed, thus line drawings of a plurality of colors are drawn on the canvas of the monitor 90. The touch pen 28 contacts the eraser region 212 to display the eraser on the monitor 90, and then the touch pen 28 is moved, tracing the drawn line drawing on the canvas of the monitor 90, whereby the drawn line drawing can be erased. Thus pictures can be freely drawn on the canvas of the monitor 90 as pictures are drawn on an actual canvas. Sound Making Processing The sound making processing according to the first example will be explained with reference to the flow chart of FIG. 9. The sound making processing will be explained by using the grand piano of a sample picture of FIG. 7, but the sound processing can be conducted by using the line drawing on the canvas shown in FIG. 8. First, it is judged whether or not the touch pen 2 has selected the conductor baton (step S20). When a game player contacts the touch pen 28 to the conductor baton region 214, the conductor baton 502 is displayed on the monitor 90. Then, it is judged whether or not the touch pen 28 is on the drawing tablet (step S21). Further it is judged whether the pen button 28a is being pressed (step S22). When the game player contacts the touch pen 28 to the drawing tablet 24, the sound making processing unit 108 outputs a position signal to the coordinate conversion unit 116, which converts the position signal to an address of the buffer memory 120. Subsequently the color information reading unit 118 reads a color signal at the converted address of the buffer memory 120, and outputs the color signal to the sound making process unit 108 (step S23). Then, it is judged whether or not a change of the color information is present (step S24). In the absence of a change of the color information, it is judged whether or not it is immediately after the pen button 28a was pressed (step S25). Unless it is immediately after the pen button 28a was pressed, the process is returned to Step S20. When it is immediately after the pen button 28a being pressed or there is a change of colors, the sound making processing unit 108 judges whether the read color information is transparent or black (step S26). This is because no sounds are generated if the color information is transparent or black (step S26). When the selected color information is black, glowing powder is displayed (step S27), and the step is returned to Step S20. Unless the read color information is transparent or black, the sound making processing unit 108 decides in accordance with the color information a sound to be made (step S28). A sound making frequency table which decides amplitudes of frequencies of sounds corresponding to the respective color information is prepared, and based on the sound making frequency table a frequency amplitude is decided. Subsequently the sound making processing unit 108 outputs a decided sound signal and outputs the same to the monitor 90 through the audio terminal 76 to make a sound (step S29). In FIG. 7, the conductor baton 502 is positioned on a yellow note 504, and a sound preset for yellow, for example, B of the piano, is made. By thus moving the touch pen 28 on the drawing tablet 24, and pressing the pen button 28a, sounds corresponding to commanded colors can be made. Furthermore, as shown in FIG. 7, a picture is drawn in colors which correspond to the notes of the key board of the piano, and it is possible that simple music can be freely played by commanding keys of the piano with the conductor baton. By the above-described sound making processing, it is possible not only for pictures to be drawn on the monitor, but also for various games, such as making sounds, playing music,etc., to be played using the pictures. A Second Example of the Video Game Next, a second example of the video game of the video game device according to the present embodiment will be explained with reference to FIGs. 11 and 12. The second example is different from the first example in the sound making processing. Sound Making Processing The sound making processing according to the present example will be explained with reference to the flow chart of FIG. 10. The sound making processing will be explained for a sample picture of the grand piano shown in FIG. 11. First, it is judged which kind of conductor baton has been selected by the touch pen 28 (step S120). In the present example, in addition to a conductor baton, for selecting the usual organ sounds, conductor batons which can make timbres of animals can be selected. As shown in FIG. 11, the different kinds of conductor batons can be displayed in a tool box 520 on the screen, and a game player operates the touch pen 28 to position the cursor on a picture of an animal in the tool box 52 and presses the pen button 28a to select the required animal. For example, when the cat picture 522 in the tool box 520 is selected, as shown in FIG. 11 a conductor baton 524 having the cat picture on the tip portion is displayed. Then, it is judged whether or not the touch pen 28 is on the drawing tablet 24 (step S121), and further it is judged whether or not the pen button 28a is being pressed (step S122). When the game player contacts the touch pen 28 to the drawing tablet 24, the sound making processing unit 108 outputs a position signal to the coordinate conversion unit 116, and there the position signal is converted to an address of the buffer memory 120. Then, the color information reading unit 118 reads a color signal at the converted address of the buffer memory 120 and outputs the signal to the sound making processing unit 108 (step S123). Then, it is judged whether or not a change has been made to the color information (step S124). When no change has been made to the color information, it is judged whether it is immediately after the pen button 28a being pressed (step S125). Unless it is immediately after the pen button 28a being pressed, the processing is returned to step S120. When it is immediately after the pen button 28a being pressed or if there is a change of color, the sound making processing unit 108 judges whether the read color information is transparent, light blue or black (step S120). When the read color information is transparent, light blue or black, no sound is made, and the processing is returned to step S120. Unless the read color information is transparent, light blue, or black, the sound making processing unit 108 decides a sound to be made corresponding to the read color information and the kind of the conductor batons (step S127). Timbres (organ sound, dogs' sound, cats' sound, monkeys' sound, pigs' sound, and elephants' sound) are set corresponding to the kinds of the conductor batons, and a sound making frequency table which sets amplitudes of sound frequencies corresponding to respective color information is prepared, and based on a timbre and the sound making frequency table, a sound to be made is set. For example, when a cat is selected, a scale can be played using cats' sounds. Subsequently, the sound making processing unit 108 outputs a decided sound signal to the monitor 90 through the audio terminal 76, and a sound is generated (step S128). In FIG. 11, in which the cat conductor baton 524 is positioned on the yellow note 504, a sound which is preset for the cat conductor baton and the color yellow, e.g., the cats' sound in B tone, is selected. Thus by moving the touch pen 28 on the drawing tablet 24 and pressing the pen button 28a, various sounds can be made corresponding to commanded colors. Alternatively, an image of an animal from the picture book may be clicked to conduct processing of making sounds of its voice. The touch pen 28 is operated to position the cursor on the animal on the screen and is clicked. An image of the animal changes and makes sounds. The present invention is not limited to the above-described embodiment and covers other various modifications. For example, in the above-described embodiment, an infant video game device is described, but the present invention is applicable to game devices of other constitutions. Further, the present invention is applicable to an electronic tablet for electrically drawing pictures other than the game devices. Furthermore, the present invention is universally applicable to game programs for universal computers, such as personal computers, etc., and image processing, such as image programs, etc. The present invention is suitable for a video game device for playing games using monitor screens, especially for infant video game devices for playing games using pictures drawn on monitor screens by game players.
