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

  FIG. 1 is a game apparatus with a camera function corresponding to the embodiment of the present invention. This game apparatus can be realized by a mobile phone with a camera function, for example.

  In FIG. 1, reference numeral 101 denotes a CPU, which controls the entire game apparatus using programs, data, etc. stored in a RAM (Random Access Memory) 102 and a ROM (Read Only Memory) 105, and a game corresponding to the present invention. Perform the execution process. Reference numeral 102 denotes a RAM, which includes an area for reading processing programs and processing data stored in the ROM 105, and also includes a work area used when the CPU 101 executes various processes.

  Reference numeral 103 denotes an operation unit that receives an operation from a user of the game apparatus, and includes a keypad such as a numeric keypad and a jog dial. Note that the operation unit 103 includes a shutter button used when shooting using the camera unit 109.

  Reference numeral 104 denotes a speaker for reproducing a sound or the like of a game executed in the game device. When the game device is used as a mobile phone, it is also used as a speaker for calls. A ROM 105 stores a program (for example, a boot program) for controlling the entire game device. Reference numeral 106 denotes a display unit as a display screen, which is constituted by a liquid crystal screen, for example.

  A communication I / F (interface) 107 functions as an I / F for connecting to a telephone network, the Internet, or the like. Reference numeral 108 denotes a microphone that receives voice input from the user, and is used when the user uses the game apparatus as a mobile phone or plays a game by voice input.

  A camera unit 109 includes an imaging lens, a diaphragm, a shutter, an imaging device that converts an optical image into an electric signal, an A / D converter that converts an analog signal output of the imaging device into a digital signal, and the like. As the image sensor, for example, a CCD sensor or a CMOS sensor can be used. In the camera unit, the subject is imaged in accordance with the shutter button operation of the operation unit 103, and electronic image data is generated.

  Next, the content of the game performed with the game device corresponding to this embodiment will be described. In the game corresponding to this embodiment, first, “colors” to be included in the captured image are randomly specified, and the user attempts to capture an image including the specified color. It is determined whether or not the specified color is included in the captured image. If the specified color is included, the next color is specified. In this way, the game competes for how many images including the designated color can be taken within a preset time limit.

  For example, when “white” is designated, the user takes a picture including “white” and designates the corresponding part with the cursor. The game device calculates the ratio of white pixels in the cursor, and determines that it is “successful” if this ratio exceeds a certain ratio. If successful, another color is specified and the game can continue until the time limit expires. On the other hand, if it falls below a certain ratio, it is determined as “failure”, and the user can take another image or move the cursor to designate another area.

  Hereinafter, the flow of the game corresponding to this embodiment will be described in detail with reference to the flowchart of FIG. FIG. 2 is a flowchart showing an example of a game flow corresponding to the present embodiment. Note that the processing corresponding to this flowchart is realized by reading a game program stored in the ROM 105 into the ROM 102 and executing it by the CPU 101.

  First, in step S201, a game application corresponding to the present embodiment is activated. This operation is performed when the user displays the menu screen of the game to be executed on the display unit 106 and selects and executes the game corresponding to the present embodiment in the operation of the operation unit 103.

  When the game application is activated, a game start screen is displayed in step S202. After the start screen is displayed, a level selection screen is displayed in step S203. An example of this level selection screen is as shown in FIG.

  In FIG. 3, reference numeral 300 denotes the entire display screen in the display unit. In this embodiment, there are three levels A, B, and C as selectable levels. Each level is indicated by buttons 301 to 303, and the user can select any level and execute the game by operating the operation unit 103.

  In step S204, it is determined whether or not level selection is accepted in the screen display of FIG. If the selection is accepted (“YES” in step S204), the process proceeds to step S205. On the other hand, when the selection is not accepted (“NO” in step S204), the process waits until the selection is accepted.

  In the present embodiment, when level A (301) is selected, color designation is performed only with hiragana on the color designation screen displayed thereafter. For example, “white” is displayed when white is specified, and “black” is displayed when yellow is specified.

  Next, when level B (302) is selected, color designation is performed by either hiragana or katakana on the color designation screen displayed thereafter. Here, hiragana and katakana are selected at random. For example, even when the same white is designated, “Shiro” may be displayed or “White” may be displayed.

  Further, at level C (303), on the color designation screen displayed thereafter, the designation of the color is performed in either Hiragana, Katakana or Kanji in Japanese, or in English using alphabets. Here, selection of hiragana, katakana, kanji, and alphabet is performed at random. Therefore, even when the same white is designated, any one of “shiro”, “white”, “white”, and “white” is displayed at random.

  The assignment of characters to each level is described only as an example, and is not limited to the above pattern.

  After the level selection is performed, in step S205, it is determined whether or not the game start button has been operated. If the start button is operated (“YES” in step S205), the process proceeds to step S206. On the other hand, if the start button is not operated (“NO” in step S205), the process waits until the start button operation is accepted.

  In step S206, counting by a timer is started. This count can be executed based on the internal clock of the CPU. The count value by the timer corresponds to the time limit of the game, and the upper limit, that is, the time limit can be set to, for example, “1 minute”. Next, in step S207, based on the count value of the timer, it is determined whether or not the time limit has elapsed (time up) from the start of the game in step S205. If the time is up (“YES” in step S207), the process proceeds to step S218. On the other hand, when the time limit is not reached (“NO” in step S207), the process proceeds to step S208 to perform color designation display.

  An example of the color designation display screen here is as shown in FIG. In FIG. 4, a color designation area 401 is displayed on the screen 300. In FIG. 4, “Kiro” is displayed as the designated color.

  Next, in step S209, it is determined whether the user has operated the shutter button of the operation unit 103 to take an image. If image shooting has been performed (“YES” in step S209), the process proceeds to step S210. In step S <b> 210, a screen showing image data acquired by photographing and a cursor for designating an area is displayed on the display unit 106. A display example at this time is shown in FIG.

  In FIG. 5a, a captured image is displayed in the image display area 501, and a cursor 502 is displayed in the captured image. The cursor 502 is used to determine an area for determining whether or not the specified color is included in the captured image, and is moved by the user in the image display area 501 in the vertical and horizontal directions by operating the operation unit 103. Can do. The user operates the operation unit 103, moves the cursor to an area corresponding to the color specified in the color specification area 401, and operates a button functioning as a determination button in the operation unit 103. Thereby, the cursor position is determined.

  The user can move the cursor in the upper left direction to specify the region of “black” from the state of FIG. 5a, and determine the cursor position on the yellow flower as shown in FIG. 5b.

  In step S211, it is determined whether the cursor position has been determined and an area for color determination has been set. If the cursor position is determined (“YES” in step S211), the process proceeds to step S212. On the other hand, if the cursor position is not determined (“NO” in step S211), the captured image and cursor display are continued, and the process waits until the cursor position is determined.

  In step S212, color determination is performed on the image included in the determined cursor. This color determination can be performed on the basis of, for example, calculating an average of RGB values of all the pixels in the cursor and determining whether the average value falls within a preset RGB value range for the specified color. In the case of yellow, for example, when it is included in the range of R: 255 to 240, G: 255 to 220, and B130 to 0, it is determined in advance to determine “yellow”, and the RGB value of the pixel in the cursor area When the average is included in this range (“success” in step S212), the process proceeds to step S214. On the other hand, when the average of the RGB values of the pixels in the cursor area is out of this range (“failure” in step S212), the process proceeds to step S213.

  In step S213, a screen display as shown in FIG. 6A is made as a failure display. At this time, a “x” mark 601 indicating “failure” is displayed large on the screen. Then, it returns to step S207 and it is determined again whether the time limit has passed. In step S214, a screen display as shown in FIG. 6B is made as a success display. At this time, a “◯” mark 602 indicating “success” is displayed large on the screen.

  For example, in the case as shown in FIG. 5a, when the cursor position is determined in an area where a human hand is captured, and the RGB values of the pixels included in this area are averaged, the position is out of the above range. A failure display as shown in FIG. 6a is made. On the other hand, in the case as shown in FIG. 5b, the cursor position is determined in a region where a yellow flower is reflected, and the RGB values of the pixels included in this region are averaged and included in the above range. Displays a success as shown in FIG. 6b.

  After the success display is performed in step S214, the score is updated in step S215. That is, the user's score is updated by one. This score is reset to “0” at the start of the game. Thereafter, the process proceeds to step S216, and it is determined again whether or not the time limit has elapsed. If the time limit has elapsed (“YES” in step S216), the process proceeds to step S218. On the other hand, when the time limit has not elapsed ("NO" in step S216), the process proceeds to step S217.

  In step S217, the color designation is updated. That is, the screen of FIG. 4 is displayed again, and another color is designated and displayed in the color designation area 401. At this time, the character for color designation is performed using any one of hiragana, katakana, kanji, and alphabet according to the level set in step S203. In other words, if it is level A (301), designation is always made with hiragana, and if it is level C, designation is made in any of the four types from hiragana to alphabet. Thereafter, the process proceeds to step S209, and image shooting is performed.

  If it is determined in step S207 or step S216 that the time is up ("YES" in step S207 or step S216), the process proceeds to step S218. In step S218, a time-up display 701 as shown in FIG. 7 is performed to notify that the game is over. Thereafter, the process proceeds to step S219, and a game score is displayed. An example of the display screen at this time is as shown in FIG. In FIG. 8, the score is displayed in the score display area 801.

  In the above-described embodiment, the case where the game is continued by shooting a new image when failure display is performed in step S213 is described. However, the embodiment of the present invention is limited to this. It is not a thing. For example, when a failure display is made, it is possible to selectively accept either further movement of the cursor or new image shooting. In other words, if the user determines that the specified color is not included in the image, a new image is taken, whereas if the user determines that the cursor position is not determined well and the failure is determined, the cursor position is changed. It is also possible to perform color determination again after adjustment.

  In the above embodiment, the color determination process is performed based on the average of the RGB values of all pixels, but the details of the color determination process are not limited to this.

  For example, success / failure may be determined based on the number of pixels belonging to the range set for the designated color. More specifically, when the number of pixels corresponding to 80% or more of the number of pixels included in the area specified by the cursor falls within the above range, it is determined as “successful”, and when it is below 80%, “failure”. Can be determined.

  When such a determination method is employed, the threshold value can be changed according to the level set in step S204. For example, at level A (301), the success probability can be increased by setting the threshold value to 40%. Accordingly, the level B may be set to 60% and the level C may be set to 80%. According to this, it becomes possible to change the difficulty level of a game according to a setting level, ie, a user's level, and to improve gameability more.

  As described above, according to the present invention, it is possible to execute a game by competing for the number of images taken within a time limit for an image including a designated color. Further, by changing the character for color designation according to the user's level, it is possible to further improve the game play.

  The above processing (for example, processing according to the flowchart shown in FIG. 2 in the above embodiment) is stored as a program in a storage medium such as a CD-R, ROM, DVD-ROM, or MO, and stored in this storage medium. By causing the computer to read (install or copy) the program, the computer can perform the above processing. Therefore, such a program and a storage medium also belong to the category of the present invention.
