  According to these configurations, an image created by the user of the image display device 100 is displayed with high luminance, and an image other than that is displayed with low luminance lower than the image created by the user. For this reason, even if the creator displays different images, the user who visually recognizes the images can easily and quickly distinguish whether the image is an image created by the user.

  In the present embodiment, the image display device 100 has been described as turning on the backlight 100i while the download image is displayed on the LCD panel 100h and turning off the backlight 100i while the user image is displayed on the LCD panel 100h. However, it is not limited to this. For example, the image display device 100 may employ a configuration in which the backlight 100i is turned on while the user image is displayed on the LCD panel 100h, and the backlight 100i is turned off while the download image is displayed on the LCD panel 100h.

  In the present embodiment, the image display device 100 has been described as turning on the backlight 100i while the download image is displayed on the LCD panel 100h and turning off the backlight 100i while the user image is displayed on the LCD panel 100h. However, it is not limited to this. For example, the image display apparatus 100 turns on the backlight 100i both while the download image is displayed on the LCD panel 100h and while the user image is displayed on the LCD panel 100h, but the download image is displayed on the LCD panel 100h. A configuration in which the backlight 100i is lit with a higher illuminance during the period than when the LCD panel 100h displays the user image can be employed. Conversely, the image display apparatus 100 employs a configuration in which the backlight 100i is lit at a lower illuminance while the download image is displayed on the LCD panel 100h than when the user image is displayed on the LCD panel 100h. Also good.

(Embodiment 5)
Next, a fifth embodiment of the present invention will be described. In the present embodiment, the image display device 100 detects the user when the main power is off and the first image to be displayed after the main power is turned on is a download image. Within a predetermined time, the power is turned on and a download image is displayed. On the other hand, when the image display apparatus 100 is in a state where the main power supply is OFF and the first image to be displayed after the transition to the ON state of the main power supply is a user image, the image display apparatus 100 detects the user. After a predetermined time, the power is turned on and the user image is displayed. Similar to the fourth embodiment, the image display apparatus 100 according to the fifth embodiment includes hardware as illustrated in FIG.

  The state where the main power supply is OFF means a state where the power consumption of the image display apparatus 100 is lower than that when the main power supply is ON. Specifically, the CPU 100a in FIG. In this state, power is supplied to the ROM 100b, the RAM 100c, and the infrared sensor 100m, but power is not supplied to the other hardware shown in FIG. 2, or less power is supplied than when the main power supply is ON.

  The image display apparatus 100 includes the image information storage unit 101a, the user information storage unit 101b, the information acquisition unit 102, the specifying unit 103, the conversion unit 104, and the display unit illustrated in FIG. 105, an information receiving unit 106, and an information input unit 107. Since these functional units are the same as the functional units described in the fourth embodiment, redundant description is omitted. Further, the CPU 101a of the image display device 100 functions as the detection unit 109 in FIG. 13A in cooperation with the infrared sensor 100m in FIG.

  The image display apparatus 100 according to the fifth embodiment performs the slide show display process of FIG. 14 on the CPU 100a that implements the display unit 105 after executing the same process as the process of steps S21 to S26 in the image display process of FIG. To do.

  When the slide show display process of FIG. 14 is started, the CPU 100a initializes the value of the counter CT that counts the time when the user is not detected in the state where the main power is ON with the value “0” (step S61). Next, the CPU 100a determines whether or not a display end instruction signal has been input from the operation button 100j (step S62). At this time, when it is determined that the display end instruction signal is not input (step S62; No), the CPU 100a determines whether or not the main power supply is in an OFF state (step S63). At this time, if the CPU 100a determines that the main power supply is not in the OFF state (that is, is in the ON state) (step S63; No), it determines whether or not the detection unit 109 in FIG. 13A has detected the user. (Step S64).

  Specifically, the detection unit 109 determines whether or not the signal value of the signal output from the infrared sensor 100m in FIG. 2 is greater than the predetermined signal value output when the infrared sensor 100m receives a predetermined amount of light. If the signal value of the output signal is larger than the predetermined signal value, the user who is closer to the image display apparatus 100 than the predetermined range is detected. On the other hand, the detection unit 109 does not detect the user when the signal value of the output signal is equal to or less than the predetermined signal value.

  If it is determined in step S64 in FIG. 14 that the user has been detected (step S64; Yes), the CPU 100a returns the value of the counter CT for measuring the time during which the user has not been detected to the value “0” (step S65). Next, the display unit 105 realized by the CPU 100a in cooperation with the LCD panel 100h or the like displays an image (a user image or a download image) to be displayed next based on, for example, a software random number. The determined image is displayed, and the determined image is displayed (step S66). Thereafter, the CPU 100a repeats the above process from step S62.

  In step S64 of FIG. 14, when determining that the user has not been detected (step S64; No), the CPU 100a increments the value of the counter CT by “1” (step S67). Thereafter, the CPU 100a determines whether or not the value of the counter CT has exceeded a predetermined threshold Th (Step S68). Note that information representing the threshold Th is stored in, for example, the hard disk 100d in FIG. Moreover, the suitable value of threshold value Th can be determined by an expert by experiment.

  In step S68, when the CPU 100a determines that the value of the counter CT has not exceeded the predetermined threshold Th (step S68; No), the above processing is repeated from step S62. On the other hand, if the CPU 100a determines that the value of the counter CT exceeds the predetermined threshold Th (step S68; Yes), for example, based on the software random number, the CPU 100a first displays after the main power supply is turned on. An image (hereinafter referred to as a start image) is determined (step S69), and an image ID of the determined image (hereinafter referred to as a start image ID) is stored in a predetermined variable (step S70). Next, the CPU 100a outputs a signal instructing to turn off the main power to a power supply circuit (not shown), thereby causing the image display device 100 to transition to a state where the main power is turned off (step S71). ). Thereafter, the CPU 100a repeats the above process from step S62.

  In step S63, when the CPU 100a determines that the main power supply is in an OFF state (step S63; Yes), it determines whether or not the detection unit 109 has detected a user (step S72), as in step S64. At this time, if the CPU 100a determines that the detection unit 109 has not detected the user (step S72; No), the above processing is repeated from step S62. On the other hand, when the CPU 100a determines that the detection unit 109 has detected the user (step S72; Yes), the start image identified by the start image ID stored in the variable in step S70 is step S26 in FIG. It is determined whether or not the download image is specified in (Step S73).

  At this time, if the CPU 100a determines that the start image is a download image (step S73; Yes), the CPU 100a outputs a signal instructing to turn on the main power within a predetermined time to a power supply circuit (not shown). Thus, the image display device 100 is shifted to the main power ON state (step S74). After that, the display unit 105 realized by the CPU 100a cooperating with the LCD panel 100h or the like displays the download image that is the start image (step S75), and then repeats the above processing from step S62.

  Note that information representing the predetermined time is stored, for example, in the hard disk 100d of FIG. A suitable value for the predetermined time can be determined by a person skilled in the art through experiments.

  On the other hand, if the CPU 100a determines that the start image is not a download image (that is, a user image) (step S73; No), a signal for instructing to turn on the main power after a predetermined time is not shown. The power is supplied to the power supply circuit, and the image display device 100 is shifted to the main power ON state (step S76). After that, the display unit 105 realized by the CPU 100a cooperating with the LCD panel 100h displays the user image as the start image (step S77), and then repeats the above processing from step S62.

  If it is determined in step S62 that the display end instruction signal has been input (step S62; Yes), the CPU 100a ends the slide show display process.

  According to these configurations, an image created by a user of the image display device 100 is displayed a predetermined time after the user is detected, and an image created by a person different from the user of the image display device 100 is detected by the user. Will be displayed within a predetermined time. For this reason, even if the creator displays different images, the user who viewed the images can easily distinguish whether the image is an image created by the user, but the displayed image itself is unified. The loss of sex can be prevented.

  The image display apparatus 100 is in a state in which the main power is turned off and the power is turned on after a predetermined time (not within a predetermined time) after detecting the user when the start image is a download image. If the downloaded image is displayed, the main power is OFF, and the start image is a user image, the power is turned ON within a predetermined time (not after a predetermined time) after the user is detected. A configuration for displaying an image may be employed.

(Modification)
Next, a modification of the fifth embodiment will be described. In the modification of the present embodiment, the image display device 100 has a predetermined time after detecting the user when the backlight 100i in FIG. 2 is turned off and the next image to be displayed is a download image. The downloaded image is displayed after the backlight 100i is turned on. On the other hand, when the backlight 100i is turned off and the next image to be displayed is a user image, the image display device 100 turns on the backlight 100i after a predetermined time after detecting the user. The user image is displayed.

  In the modification of the fifth embodiment, the image display apparatus 100 executes the same process as the process from step S21 to step S26 in the image display process of FIG. 9, and then executes the slide show display process of FIG. To do.

  When the slide show display process in FIG. 15 is started, the display unit 105 determines whether or not a display end instruction signal is input from the operation button 100j after initializing the value of the counter CT with the value “0” (step S81). (Step S82). At this time, when it is determined that the display end instruction signal is not input (step S82; No), the display unit 105 determines whether the backlight 100i is turned off (that is, is OFF). (Step S83). At this time, if the display unit 105 determines that the backlight 100i is not OFF (that is, is ON) (step S83; No), whether or not the detection unit 109 has detected the user as in step S64 of FIG. Is determined (step S84).

  At this time, if it is determined that the user has been detected (step S84; Yes), the display unit 105 returns the value of the counter CT to the value “0” (step S85). On the other hand, if it is determined that the user has not been detected (step S84; No), the display unit 105 increments the value of the counter CT by “1” (step S86), and then the value of the counter CT is set to a predetermined threshold value. It is determined whether or not Th has been exceeded (step S87).

  In step S87, when the display unit 105 determines that the value of the counter CT has exceeded the predetermined threshold Th (step S87; Yes), the display unit 105 turns off the backlight 100i (step S88).

  After step S85 or step S88, or when it is determined in step S87 that the value of the counter CT has not exceeded the predetermined threshold value Th (step S87; No), the display unit 105 is based on, for example, software random numbers. An image to be displayed (which may be a download image or a user image) is determined, and the determined image is displayed (step S89). Then, the display part 105 repeats the said process from step S82.

  In step S83, when determining that the backlight 100i is OFF (step S83; Yes), the display unit 105 determines whether or not the detection unit 109 has detected the user as in step S64 of FIG. Step S90).

  At this time, if the display unit 105 determines that the user has not been detected (step S90; No), the display unit 105 displays the image (step S91) and performs the above-described processing from step S82, as in step S89. repeat.

  In step S90, when the display unit 105 determines that the detection unit 109 has detected the user (step S90; Yes), the display unit 105 determines an image to be displayed next, similarly to step S32 in FIG. It is determined whether the determined image is a user image or a download image (step S92). At this time, when the display unit 105 determines that the next image to be displayed is a download image (step S92; Yes), the display unit 105 turns on the backlight 100i within a predetermined time (step S93). Thereafter, the display unit 105 displays the download image determined as the next image to be displayed (step S94), and then repeats the above-described processing from step S82.

  In contrast, if the display unit 105 determines that the next image to be displayed is not a download image (that is, a user image) (step S92; No), the display unit 105 turns on the backlight 100i after a predetermined time (step S95). ). Thereafter, the display unit 105 displays the user image determined as the next image to be displayed (step S96), and then repeats the above-described processing from step S82.

  If it is determined in step S82 that a display end instruction signal has been input (step S82; Yes), the display unit 105 ends the slide show display process.

  According to these configurations, when the LCD panel 100h displays an image created by the user of the image display device 100, the backlight 100i, which is the illumination, is turned on after a predetermined time since the user is detected. When the LCD panel 100i displays an image created by a person different from the user of the image display device 100 by illuminating 100h, the backlight 100i as the illumination is turned on within a predetermined time after the user is detected. Illuminate the LCD panel 100h. For this reason, even if the creator displays different images, the user who viewed the images can easily distinguish whether the image is an image created by the user, but the displayed image itself is unified. The loss of sex can be prevented.

  In the modification of the present embodiment, the image display apparatus 100 detects the user (predetermined) when the backlight 100i in FIG. 2 is turned off and the next image to be displayed is determined as a download image. A configuration in which the downloaded image is displayed after the backlight 100i is turned on after a predetermined time (not within the time) can be adopted. Further, in this configuration, when the backlight 100i is turned off and the next image to be displayed is determined as a user image, the image display device 100 detects a user (not after a predetermined time). A configuration in which the user image is displayed after the backlight 100i is turned on within the time can be employed.
