In this embodiment, it is assumed that the Internet 62 is connected to the DPF 2 via the network terminal 22, the server 64 is connected to the Internet 62, and the network connection unit 44 is transmitted from the server 64. It is assumed that various information is received and various information is transmitted to the server 64.

  As shown in FIG. 2, the operation key 22, the memory card slot 18, and the USB port 20 are connected to the CPU 30. Further, the clock unit 56, the display control unit 58, and the reproduction control unit 60 are connected to the CPU 30. The clock unit 56 manages time and date. The display control unit 58 performs display control of images and the like displayed on the LCD panel 6, and the reproduction control unit 60 performs reproduction control of music and audio output from the speaker 12.

  In the DPF 2 according to this embodiment, the front direction of the DPF 2 is imaged by the camera 10, the face image detection unit 38 detects the face image of the user based on the imaging result of the camera 10, and the detection result by the face image detection unit 38 Based on the above, the age of the user is estimated by the age estimating unit 40, and the image displayed on the LCD panel 6 and the sound and music to be reproduced by the speaker 12 are controlled based on the estimation result by the age estimating unit 40. Hereinafter, with reference to the flowchart shown in FIG. 5, a process for controlling an image to be displayed on the LCD panel 6 in the DPF 2 according to this embodiment will be described.

  First, the CPU 30 determines whether or not the power supply control unit 32 has turned on the power of the DPF 2 when the power switch 14 is pressed by the user (step S10). When the power of the DPF 2 is turned on in step S10 (step S10, Yes), the CPU 30 causes the camera 10 to image the front direction of the DPF 2 (step S11).

  Next, the CPU 30 performs face image detection from the images captured by the camera 10 in step S11 in the face image detection unit 38, and determines whether or not at least one face image has been detected. (Step S12). When at least one face image is detected in step S12 (step S12, Yes), the CPU 30 determines that there is at least one viewer of the DPF 2, and first, the registration recorded in the registration information recording unit 54 is performed. A person's face image (taro.jpg, hanako.jpg, sadako.jpg shown in FIG. 4) is read. At this time, the registrant's age has reached a predetermined age (for example, an age classified as a so-called adult, such as 18 years of age or older), and the face under the registration information that is registered separately from the registration information of other registrants The image is not read. That is, a face image of a registrant who is a predetermined age or less is read.

  Then, the CPU 30 obtains the similarity between the viewer's face image detected by the face image detection unit 38 and the registrant's face image recorded in the registration information recording unit 54 in the similarity determination unit 36. It is determined whether or not the obtained similarity is a predetermined value or more (step S13). Note that the predetermined value is set in advance, and if the similarity is equal to or higher than the predetermined value (step S13, Yes), the CPU 30 records the viewer located in front of the DPF 2 in the registered information recording unit 54. It is determined that you are one of the registered users. On the other hand, when the degree of similarity is smaller than the predetermined value (step S13, No), the CPU 30 determines that the viewer does not correspond to any registrant recorded in the registration information recording unit 54.

  If it is determined in step S13 that the degree of similarity is equal to or greater than a predetermined value (step S13, Yes), the CPU 30 executes a registration information update process (step S14). FIG. 6 is a flowchart for explaining the update process in step S14 of FIG.

  First, the CPU 30 acquires the update date and time of the viewer's registration information recorded in the registration information recording unit 54 and the current date and time from the clock unit 56, and compares the acquired update date and time with the current date and time to update. It is determined whether or not a predetermined time has elapsed since the date and time (step S30). Note that the predetermined time is set in advance, and is set to a period in which the face image can be updated before the face of the child who is a registrant grows significantly, for example, three months.

  When it is determined in step S30 that the predetermined time or more has passed since the update date and time (step S30, Yes), the CPU 30 in the registration information update unit 34, the viewer information recorded in the registration information recording unit 54 is displayed. The face image is updated to the viewer's face image detected by the face image detection unit 38 (step S31). Then, the CPU 30 rewrites the update date and time of the viewer's face image recorded in the registration information recording unit 54 to the current date and time acquired from the clock unit 56 in the registration information update unit 34, thereby replacing the old update date and time with the new one. Update to the update date and time (step S32). On the other hand, when it is determined in step S30 that the predetermined time or more has not elapsed since the update date (step S30, No), the CPU 30 determines that there is no need to update the viewer's face image, and FIG. The update process in step S14 is terminated.

  On the other hand, when it is determined in step S13 of FIG. 5 that the similarity is smaller than the predetermined value (No in step S13), the CPU 30 detects the viewer detected by the face image detection unit 38 in the age estimation unit 40. The viewer's age is estimated based on the face image (step S15). And CPU30 discriminate | determines whether the viewer's age estimated in the age estimation part 40 is below a predetermined age (step S16). The predetermined age is set in advance, and is set to an age classified as a so-called child, for example, 18 years old or less as described above.

  When it is determined in step S16 that the age of the viewer is higher than the predetermined age (No in step S16), or when it is determined in step S12 that the face image detection unit 38 has not detected a face image (step S16). In S12, No), the CPU 30 reads the image file or folder (see FIG. 3) classified as “adult” from the related information recording unit 52, and the image based on the read image file or the image file in the folder. The (adult image) is reproduced and displayed on the LCD panel 6 via the display control unit 58 (step S17). At this time, one image based on one image file is displayed or a plurality of images based on a plurality of image files in a folder are displayed in a slide show format according to the user's playback settings.

  On the other hand, when it is determined in step S16 that the viewer's age is equal to or lower than the predetermined age (step S16, Yes), or after the update process is completed in step S14, the CPU 30 causes the crying determination unit 42 to start from the microphone 8. The input voice is acquired, crying is determined based on the acquired voice, and it is determined whether the viewer is crying based on the determination result (step S18). If it is determined in step S18 that the viewer is crying (step S18, Yes), the CPU 30 sorts the image file or folder classified as “for crying children” from the related information recording unit 52 (see FIG. 3). ), And an image based on the read image file or the image file in the folder (a crying child image) is reproduced and displayed on the LCD panel 6 via the display control unit 58 (step S19). At this time, similarly to the processing in step S17, one image is displayed or a plurality of images are displayed in a slide show format according to the user's reproduction setting.

  On the other hand, if it is determined in step S18 that the viewer is not crying (No in step S18), the CPU 30 determines that the image file or folder classified as “for children” from the related information recording unit 52 (FIG. 3). Reference) is read, and an image (child image) based on the read image file or the image file in the folder is reproduced and displayed on the LCD panel 6 via the display control unit 58 (step S20). At this time, similarly to the processing in steps S17 and S19, one image is displayed or a plurality of images are displayed in a slide show format according to the user's reproduction setting.

  Next, the CPU 30 determines whether or not the power supply control unit 32 has turned off the power of the DPF 2 when the power switch 14 is pressed by the user (step S21). When the power of the DPF 2 is not turned off in step S21 (step S21, No), the CPU 30 returns to the process of step S11 until it is determined that the power of the DPF 2 is turned off in step S21 (step S21, Yes). , Steps S11 to S21 are repeated.

  When it is determined in step S18 in FIG. 5 that the viewer is crying (step S18, Yes), the time during which the viewer keeps crying, that is, the time from when the viewer starts to cry until the crying ends is measured. In addition, it is possible to control display of an image on the LCD panel 6 based on the measurement result. Hereinafter, referring to the flowchart shown in FIG. 7, it is determined that the viewer is crying in step S18 of FIG. 5, and after displaying the image for children crying in step S19, the power of the DPF 2 is turned off in step S21. A process executed before the determination of whether or not has been performed will be described.

  First, the CPU 30 starts measuring the time from when the viewer starts crying until ending the crying (step S40). Specifically, when it is determined in step S18 in FIG. 5 that the viewer is crying, the current date and time are acquired from the clock unit 56, and the acquired date and time are temporarily stored in a buffer memory or the like (not shown). Then, the CPU 30 again acquires the voice input from the microphone 8 in the cry determination unit 42, and determines whether or not the viewer is still crying based on the acquired voice (step S41). When it is determined in step S41 that the viewer is still crying (step S41, Yes), the CPU 30 acquires the current date and time from the clock unit 56, and the viewer starts crying based on the acquired current date and time. It is determined whether or not a predetermined time has elapsed from the specified time (date and time temporarily stored in the buffer memory or the like) (step S42). The predetermined time is set in advance, for example, 5 minutes, such as 5 minutes, so that the crying viewer can discriminate that he / she will not stop crying even if he / she views the crying child image displayed on the LCD panel 6. .

  If it is determined in step S42 that the predetermined time has not elapsed (step S42, No), the CPU 30 returns to the process of step S41. On the other hand, when it is determined in step S42 that the predetermined time has elapsed (step S42, Yes), the CPU 30 determines that the viewer does not stop crying even if the viewer views the crying child image displayed on the LCD panel 6. Then, the time measurement is finished (step S43). Specifically, the date and time temporarily stored in the buffer memory or the like is deleted. Then, the CPU 30 stops the power supply to the DPF 2 in the power supply control unit 32, that is, automatically (forcibly) turns off the power of the DPF 2 (step S44). If it is determined in step S41 that the viewer is not crying, that is, if the viewer stops crying (step S41, No), the CPU 30 has viewed the child image that the viewer displays on the LCD panel 6. Thus, it is determined that the crying has stopped, and the measurement of the time from when the viewer starts crying until the crying ends is finished (step S45).

  In the process shown in FIG. 7, the power of the DPF 2 is automatically turned off when the time from when the viewer starts to cry until the end of crying is a predetermined time or longer. It is also possible to automatically turn off the power of the DPF 2 when the age is unidentified. That is, when the viewer is one of the registrants recorded in the registration information recording unit 54, the CPU 30 determines whether the viewer is three years old or less from the age of the viewer recorded in the registration information recording unit 54. Is determined. When the viewer is not recorded in the registered information recording unit 54, the CPU 30 determines whether or not the viewer is under 3 years old from the age of the viewer estimated by the age estimating unit 40. If it is determined that the child is under 3 years old, the CPU 30 determines that the viewer is of an unidentified age and may destroy the DPF 2 by defeating it so that the viewer cannot see it. Therefore, the power supply control unit 32 stops the power supply to the DPF 2.

  Next, referring to the flowchart shown in FIG. 8, it is determined in step S18 in FIG. 5 that the viewer is crying, and after displaying the crying child image in step S19, the DPF 2 is turned off in step S21. Another process executed before the determination as to whether or not it has been performed will be described. In addition, since the process of step S50-S53, S55 is the same as the process of step S40-S43, S45 shown in FIG. 7, description is abbreviate | omitted.

  After finishing the time measurement in step S53, the CPU 30 determines that the viewer does not stop crying even if he / she views the crying child's image displayed on the LCD panel 6, and displays another different image on the LCD panel 6. It is displayed (step S54). Specifically, other image files or other folders classified as “for crying children” are read, and images based on the read other image files or image files in other folders (images for crying children) Then, it is reproduced and displayed on the LCD panel 6 via the display control unit 58.

  In addition, after the time measurement is ended in step S55, the CPU 30 stops the viewer from crying the display image displayed on the LCD panel 6 from when the viewer starts to cry until the crying ends. It is evaluated that the image can be transmitted (step S56). Specifically, 1 count is added to the image file of the display image, which indicates that the viewer can cry before the predetermined time has elapsed.

  Next, the CPU 30 generates ranking information related to the display image displayed on the LCD panel 6 based on the evaluation result in step S56, and associates the generated ranking information with the display image displayed on the LCD panel 6. Manage (step S57). Specifically, the CPU 30 adds 1 count added to the display image in step S56 to the count added in the past with respect to the display image (that is, count + 1 count in the past), for example, FIG. As shown in FIG. 5, the ranking information is generated by adding the count number added to the image file of the display image classified as “for crying children” in the table recorded in the related information recording unit 52.

  That is, the image file α. The information “count: 15” added to bmp is the image file α. This shows that bmp was evaluated 15 times as an image file that could stop the viewer from crying before the predetermined time passed. Similarly, the image file β. bmp is 0 times, the image file γ. bmp 7 times, folder α 14 times, folder β. bmp indicates that the evaluation is performed once and the folder γ is evaluated eight times. The CPU 30 generates ranking information based on information added to the image file and the folder. That is, in FIG. 9, the CPU 30 is ranked first: image file α. bmp, second place: image file γ. bmp, third place: image file β. Ranking information called bmp is generated. Similarly, 1st place: folder α, 2nd place: folder γ. bmp, 3rd place: ranking information of folder β is generated. Then, the CPU 30 manages the generated ranking information in association with files and folders classified as “for crying children”.

  In FIG. 9, the folder is evaluated and the count is added to the folder. However, the image file in the folder may be evaluated and the count added to the image file in the folder. Further, the folder and the image file in the folder may be evaluated, and the count may be added to the folder and the image file in the folder.

  When the ranking information is generated and managed as described above, the CPU 30 displays the crying child image in step S19 shown in FIG. 5 on the LCD panel 6 based on the managed ranking information. 6 controls the image to be displayed. Specifically, first, the CPU 30 reads the image file or folder ranked first (image file α.bmp or folder α in FIG. 9), and is based on the read image file or image file in the folder. An image is displayed on the LCD panel 6. Then, after the time measurement is completed in step S53 shown in FIG. 8, it is determined that the viewer does not stop crying even if the viewer ranks in the first ranked image. In step S54, another crying child image is determined. When displaying on the LCD panel 6, the CPU 30 reads the image file or folder ranked second (image file γ.bmp or folder γ in FIG. 9), and converts the image file or folder into the read image file or folder. A base image is displayed on the LCD panel 6.

  In the above-described embodiment, the image data recorded in the image recording unit 48 in the internal memory 46 is classified into “for children”, “for crying children”, and “for adults” and related in the internal memory 46. Image data recorded in the information recording unit 52 but recorded on a memory card (not shown) inserted into the memory card slot 16 or a recording medium (not shown) connected to the UBS port 20 May be classified into “for children”, “for crying children”, and “for adults” and recorded in the related information recording unit 52. Further, a related information recording unit similar to the related information recording unit 52 may be provided in a memory card or other recording medium. Further, the image data stored in the server 64 shown in FIG. 2 is downloaded at the network connection unit 44 via the Internet 62 and the network terminal 22, and the downloaded image data is “for children” and “for children who cry”. The information may be classified into “for adults” and recorded in the related information recording unit 52 in a table format.

  Further, a related information recording unit similar to the related information recording unit 52 is provided in the server 64, and the CPU 30 transmits ranking information via the network connection unit 44, and based on the ranking information transmitted from the DPF 2 or the like by the server 64. It is also possible to receive the image data transmitted from the server 64 based on the managed ranking and display the image of the received image data on the LCD panel 6. Hereinafter, with reference to the flowchart shown in FIG. 10, it is determined that the viewer is crying in step S <b> 18 in FIG. 5, and the child image (image data image transmitted from the server 64) is displayed in step S <b> 19. Other processes that are executed later and before determining whether or not the power of the DPF 2 has been turned off in step S21 will be described. Note that the processing in steps S60 to S63, S65, and S66 is the same as the processing in steps S50 to S53, S55, and S56 shown in FIG.

  The CPU 30 does not stop crying even if the viewer appreciates the crying image for the child (image data transmitted from the server 64) displayed on the LCD panel 6 after completing the time measurement in step S63. Determine and instruct the server 64 to transmit other image data. Then, the CPU 30 receives other image data transmitted from the server 64 at the network connection unit 44, and displays an image of the received other image data on the LCD panel 6 (step S64).

  Specifically, image data corresponding to an image file classified as “for a crying child” is downloaded from the server 64, and an image of the downloaded image data (an image for a crying child) is transmitted via the display control unit 58. Is displayed on the LCD panel 6. Alternatively, a plurality of image data corresponding to a plurality of image files classified as “for crying children” are downloaded in advance, temporarily stored in a buffer memory (not shown), and the image data is read from the buffer memory. You may make it read sequentially.

  Further, the CPU 30 generates ranking information related to the display image displayed on the LCD panel 6 based on the evaluation result in step S66, and transmits the generated ranking information to the server 64 (step S67). The server 64 manages the ranking information transmitted from the DPF 2 and other playback devices in association with the image data stored in the server 64. Note that the server 64 may manage rankings based on all ranking information transmitted from the DPF 2 and other playback devices, rankings of specific regions based on ranking information transmitted from specific regions, and specific rankings. It may be configured to manage the ranking of a specific group based on the ranking information transmitted from the group.

  As described above, when ranking information is generated in the DPF 2 and ranking is managed in the server 64, the server 64 manages the image for crying on the LCD panel 6 in step S19 shown in FIG. Based on the ranking, the image data is transmitted to the DPF 2, and the CPU 30 displays the image of the image data received from the server 64 on the LCD panel 6. Specifically, first, the server 64 transmits image data ranked first to the DPF 2, and the DPF 2 (CPU 30) displays the image of the image data transmitted from the server 64 on the LCD panel 6. To do. Then, after the time measurement is completed in step S63 shown in FIG. 10, it is determined that the viewer does not stop crying even if the viewer ranks in the first ranked image, and in step S64, another crying child image is displayed. When displaying on the LCD panel 6, the DPF 2 (CPU 30) instructs the server 64 to transmit other image data, and the server 64 transmits the image data ranked second to the DPF 2. , DPF2 (CPU 30) displays an image of the image data transmitted from the server on the LCD panel 6.

  In the process shown in FIG. 10, the DPF 2 generates ranking information and transmits the ranking information to the server 64. However, the server 64 may generate the ranking information. In this case, the DPF 2 (CPU 30) transmits the evaluation result (count result) for the display image displayed on the LCD panel 6 to the server 64, and the server 64 is based on the evaluation result transmitted from the DPF 2. Ranking information is generated, and ranking management based on the generated ranking information is performed. In the process shown in FIG. 10, the DPF 2 evaluates the display image displayed on the LCD panel 6 (count addition), but the server 64 evaluates the display image displayed on the LCD panel 6 (add count). ). In this case, the DPF 2 (CPU 30) transmits the measurement result of the time from when the viewer starts crying to the end of crying to the server 64, and the server 64 displays based on the time measurement result transmitted from the DPF 2. Evaluation (addition of count) is performed on the image, ranking information is generated based on the evaluation result, and ranking is managed based on the generated ranking information.

  According to the DPF 2 according to this embodiment, it is possible to control display of an image displayed on the LCD panel 6 according to the age of the viewer and whether the viewer is crying. That is, when the viewer is a child, an image preferred by the child can be displayed on the LCD panel 6. In addition, when it is determined that the viewer is a child and it is determined that the viewer is crying, an image effective for stopping the crying child can be displayed on the LCD panel 6. In addition, since the face image of a child viewer is registered and the face image is automatically updated regularly, even when the face changes due to growth, the similarity determination between the viewer and the registrant can be accurately performed. Can be executed.

  In the above-described embodiment, the display image displayed on the LCD panel 6 is similarly evaluated regardless of the length of time from when the viewer starts crying to when the crying ends, but when the viewer begins to cry. The degree of evaluation of the display image may be changed based on the length of time from when the crying is completed to when the crying is completed. For example, an image in which the viewer stops crying in 30 seconds is evaluated higher than an image in which the viewer stops crying in 3 minutes. Specifically, 3 counts for an image file of an image where the viewer stopped crying in 30 seconds, 2 counts for an image file of an image where the viewer stopped crying in 1 minute, and the viewer cried in 3 minutes One count is added to the image file of the stopped image. Accordingly, the ranking based on the generated ranking information also increases the ranking of the image file of the image that the viewer stopped crying in a short time.

  In the above-described embodiment, the case where the image data recorded in the internal memory 46 is displayed and the case where the image data downloaded from the server 64 is displayed have been described. You can also Specifically, after displaying all the images of the higher ranking image data recorded in the internal memory 46, the images of the higher ranking image data downloaded from the server 64 are displayed. Alternatively, after all the images of the top ranking image data downloaded from the server 64 are displayed, the images of the top ranking image data recorded in the internal memory 46 are displayed.

  In the above-described embodiment, the image displayed on the LCD panel 6 is the same regardless of who the viewer is, but for example, the registration information recorded in the registration information recording unit 54 includes the registrant's favorite. When the viewer is determined to be one of the registrants including the image file, the viewer's favorite image file is read and the image of the read image file is displayed on the LCD panel 6. You can also. For example, an image of the mother of the registrant can be included in the registration information of the registrant, and when the viewer is determined to be a registrant, the image of the mother of the viewer can be displayed. In this case, the registrant's favorite image file is evaluated, and registrant's personal ranking information is generated based on the evaluation result. The registrant's personal ranking information and the image data displayed on the LCD panel 6 are obtained. The ranking of individual registrants may be managed in association. In this case, when it is determined that the viewer (registrant) is crying, first, an image having a high probability that the registrant stops crying, such as an image of the registrant's mother, is displayed on the LCD panel 6. Then, when the registrant does not stop crying even after displaying all the favorite images of the registrant, that is, the image data recorded in the internal memory 46, an image with a high ranking order downloaded from the server 64 is displayed on the LCD panel. 6 is displayed.

  In addition, when providing registrant's personal favorite images, ranking information, ranking management results, etc., the registrant's growth and fashion will change the favorite images and rankings. Ranking information for each period may be generated and the ranking for each predetermined period may be managed. The ranking information for each predetermined period and the ranking management result for each predetermined period may be recorded in the internal memory 46 or the like.
