JP 2008-28452 A

  However, although an electronic device like patent document 1 is provided with the abnormality detection means which detects abnormality, generally such an abnormality detection means cannot necessarily specify an abnormal part reliably. For this reason, in many electronic devices such as Patent Document 1, when the abnormality detection unit detects an abnormality, a screen including error information is displayed on the display unit.

  Also, many of the abnormalities detected by the abnormality detection means can be solved by turning on the power again. Nevertheless, in the electronic device disclosed in Patent Document 1, it is almost determined that there is a failure immediately after detecting an abnormality without confirming whether or not it is malfunctioning, and error information is displayed on the display means. Therefore, even if it is actually just a malfunction, the user may mistakenly recognize that the device has failed. Therefore, the user may determine that the product cannot be used even though the device has not failed, and may miss an opportunity to use the product.

  In order to solve the above problems, the present invention provides an electronic device that can reduce the fact that the user cannot use the device even though the device has not failed and misses the opportunity to use the device. The purpose is to provide equipment.

  The electronic device of the present invention detects an abnormality in the own device when receiving the display means, the accepting means for accepting the ON / OFF switching of the power source, and the accepting means accepting that the power source is switched on. According to the abnormality detection means, the counting means for counting the number of times of abnormality detected by the abnormality detection means as the number of times of abnormality detection, and selecting one screen from a plurality of display screens according to the counted number of abnormality detection, Control means for displaying on the display means.

  In this way, one screen can be selected from a plurality of display screens and displayed on the display means according to the number of abnormality detections detected by the abnormality detection means.

  In addition, the electronic device detects an abnormality in the electronic device when receiving an indication means, an accepting means for accepting switching of power ON / OFF, and that the accepting means is switched on. A detecting means, a counting means for counting the number of times the abnormality has been detected by the abnormality detecting means as an abnormality detection count, and a first display screen when the counted abnormality detection count is included in a first number range. Control means for causing the display means to display a second display screen different from the first display screen when the counted number of abnormality detections is included in the second number range.

  In this way, when the abnormality detection unit detects the number of abnormalities within the first number range, the first display screen is displayed, and the abnormality detection unit displays the number of times corresponding to the second number range. When an abnormality is detected, a second display screen different from the first display screen can be displayed. Thereby, for example, on the first display screen, information for resolving the abnormality can be displayed by re-operating the device such as turning on the power again. Further, on the second display screen, information for solving the abnormality can be displayed by receiving support from the manufacturer or seller, such as contacting a support center.

  Preferably, the first display screen is a screen for prompting re-operation of the own device, and the second display screen is a screen for notifying that there is a high possibility that the own device has failed. .

  Preferably, the first display screen is a screen for prompting to turn on the power again, and the second display screen is a screen for prompting to contact a support center.

  Further, preferably, the second display screen is a screen for prompting to contact the support center, and includes a contact address to the support center and a reception time.

  That is, the present invention relates to the fact that one device is selected from a plurality of display screens according to the number of abnormality detections detected by the abnormality detection means and displayed on the display means, so that the device has not failed. Therefore, it can be reduced that the user determines that the device cannot be used and misses the opportunity to use the device.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. An example in which the present invention is applied to a digital camera will be described.
(Embodiment 1)
1. Outline of Digital Camera When the CPU 8 detects an abnormality when the user turns on the power, the display screen is switched according to the number of times the abnormality is detected.

2. Configuration FIG. 1 is a block diagram showing a circuit configuration of a digital camera according to the present embodiment. When the user presses the power button 13, a CPU (Central Processing Unit) 8 controls ON / OFF of a power source (not shown). When the power is turned on, the CCD 2 is started to be driven by a CCD (Charge Coupled Device) drive circuit 3. Next, the lens barrel 1 is initialized by the lens driving circuit 4, and the digital still camera is ready for photographing. The initialization of the lens barrel 1 includes, for example, initialization of a shutter unit, initialization of a zoom lens unit, initialization of an iris unit, initialization of a collapsible / zoom lens unit, and the like (see Japanese Patent Application Laid-Open No. 2008-122827). .

  Here, when the lens barrel 1 is initialized, the CPU 8 detects whether there is an abnormality in a part of the device. The case where there is an abnormality at the time of initialization of the lens barrel 1 is, for example, a case where the settling / zoom unit cannot be moved to the wide-angle end or a case where the iris unit cannot be opened. Further, even when a drive mechanism such as an iris unit fails, the iris unit cannot be opened. Accordingly, when the drive mechanism fails, the CPU 8 similarly detects that there is an abnormality. Here, the CPU 8 stores the detected abnormal state in the SDRAM 7 as information regarding the abnormal state. For example, when the CPU 8 detects that the iris unit cannot be opened, the CPU 8 stores information indicating an abnormality of the iris unit. Control when the CPU 8 detects an abnormality in the device will be described later.

  The lens barrel 1 is composed of units such as a retractable / zoom lens unit, a focus lens unit, an iris unit, and a shutter unit (all not shown). Light condensed through each unit of the lens barrel 1 driven by the lens driving circuit 4 enters the CCD 2 driven by the CCD driving circuit 3 and is converted into an image signal which is an electrical signal. An image signal generated by the CCD 2 is converted into image data which is a digital signal by an A / D conversion circuit 6 and stored in an SDRAM (Synchronous Dynamic Random Access Memory) 7. The image data stored in the SDRAM 7 is converted into display data by the image signal processing circuit 9 and the CPU 8 and is output to an LCD (Liquid Crystal Display) 11.

  When shooting, when the user presses the shutter button 12, the CPU 8 detects this and instructs the CCD drive circuit 3 to perform a shooting operation. The image signal taken in by the CCD 2 by shooting drive is converted into image data by the A / D conversion circuit 6, temporarily stored in the SDRAM 7, subjected to predetermined processing by the image signal processing circuit 9, and then stored as recording data in the memory. It is stored in the card 10.

  When the CPU 8 detects that there is an abnormality in the device, the CPU 8 adds 1 to the number of abnormality detections stored in the SDRAM 7. Note that the initial value of the number of times of abnormality detection is “0”. When the number of abnormality detections is added, the CPU 8 displays a display screen on the LCD 11 according to the number of abnormality detections. When the number of abnormality detections is less than a predetermined number (for example, 3 times), the CPU 8 displays the display screen 1 as shown in FIG. On the other hand, the CPU 8 displays the display screen 2 as shown in FIG. The display screen 1 is a screen that prompts the user to turn on the power again. The display screen 2 is a screen that prompts contact with the support center. The display screen 2 includes a contact information to the support center and information on the error. As a result, the user can easily contact the support center without checking the contact information of the manufacturer or distributor because the display screen includes the contact information for the support center. In addition, since the support center personnel include the support center error code on the display screen, listening to the error code from the user makes it easy to grasp the failure status of the device and reduces the number of malfunctions. To do. Note that the error code can be displayed based on information on the abnormal state stored in the SDRAM 7. At this time, the CPU 8 reads information on the abnormal state from the SDRAM 7 and converts it into the display screen 2 as shown in FIG.

  The CPU 8 performs a normal operation when it detects that there is no abnormality in the device. If the abnormality detection count stored in the SDRAM 7 at this time is set to a value other than “0”, the CPU 8 resets the abnormality detection count to “0”.

3. The LCD 11 according to the embodiment and the present invention is an example of display means. The CPU 8 is an example of a reception unit. The CPU 8 is an example of an abnormality detection unit. The CPU 8 is an example of a counting unit. The CPU 8 is an example of a control unit. Note that less than the predetermined number is an example of the first number range, and more than the predetermined number is an example of the second number range. The display screen 1 is an example of a first display screen, and the display screen 2 is an example of a second display screen.

4). Operation An example of operation of the digital still camera configured as described above will be described with reference to the flowchart of FIG. Note that the power of the digital still camera is turned off. Further, the SDRAM 7 stores the number of times of abnormality detection and is set to “0”.

  When detecting that the power button 13 has been pressed, the CPU 8 switches the power from OFF to ON (S1). When the power is turned on, the CPU 8 initializes the lens barrel 1 (S2). The CPU 8 detects whether or not the initialization of the lens barrel 1 has been completed without abnormality (S3). The CPU 8 determines whether or not an abnormality has occurred in a part of the device (S4).

  When the CPU 8 determines that an abnormality has occurred in a part of the device, the CPU 8 adds “1” to the number of times of abnormality detection stored in the SDRAM 7 (S5). Then, the CPU 8 determines whether or not the number of times of abnormality detection is a predetermined number or more (S6).

  CPU8 displays the display screen 1 of FIG. 2, when abnormality detection frequency is less than predetermined frequency (S7). On the other hand, the CPU 8 displays the display screen 2 of FIG. 3 when the number of abnormality detections is equal to or greater than the predetermined number (S8).

  In step S4, when the CPU 8 determines that no abnormality has occurred in a part of the device, the CPU 8 sets the number of abnormality detections stored in the SDRAM 7 to “0” (S9). Thereafter, the CPU 8 shifts to a normal operation (S10). Since the normal operation is general, the description is omitted.

  Thus, when the CPU 8 detects an abnormality when the user turns on the power, the display screen can be switched according to the number of times the abnormality is detected. Therefore, when the number of times the CPU 8 has detected an abnormality is small, it is possible to perform a display that can solve the abnormality by operating the device. On the other hand, when the number of times the CPU 8 has detected an abnormality is large, it is possible to display such that the abnormality can be solved by sending the device to a support center or the like for repair. That is, while the number of abnormalities detected by the abnormality detection means is small, the user is tried to solve the abnormality by causing the user to perform an operation on the device such as turning on the power again. If the problem still cannot be resolved, the user is encouraged to take action to receive support by displaying information indicating that the problem must be resolved by receiving support. Solve the problem by repairing the equipment.

5. Summary As described above, the digital camera according to the present embodiment detects an abnormality in the device when the LCD 11, the CPU 8 that accepts switching of power ON / OFF, and the CPU 8 accepting that the power is switched ON. CPU 8 for detecting, CPU 8 for counting the number of times of abnormality detection by CPU 8 as the number of times of abnormality detection, and CPU 8 for selecting one screen from a plurality of display screens according to the counted number of times of abnormality detection, and displaying on LCD 11 And comprising.

  In this way, when the power is turned on, one screen can be selected from a plurality of display screens and displayed on the LCD 11 in accordance with the number of abnormality detections detected by the CPU 8.

  In addition, in the electronic device disclosed in Patent Document 1 described in the background art, information is automatically transmitted to the support center when an abnormality is detected, so that error information is transmitted even in the case of a mere temporary malfunction. Therefore, there is a problem that the support center may have difficulty dealing with it.

Therefore, the present embodiment displays the display screen 2 as shown in FIG. 3 when the abnormality detection unit detects an abnormality of a predetermined number of times or more. As a result, the user can contact the support center when it can be determined that the device is malfunctioning.
