Information processing device, information processing method, and control program

Abstract

The present invention provides an information processing device, an information processing method, and a control program that are capable of appropriately managing the time of measurement. [Solution] The information processing device includes a measuring unit for measuring time, a communication unit capable of communicating with an external device, a detection unit for detecting communication errors with the external device, and a control unit that, when a first condition is met in which a communication error is detected by the detection unit and a time discrepancy may occur in the time measured by the measuring unit, and a second condition is met in which the cause of the communication error may be a time discrepancy, executes a predetermined operation to resolve the time discrepancy.

Claims

1. A measuring unit that measures time, A communication unit capable of communicating with external devices, A detection unit that detects communication errors with external devices, A control unit performs a predetermined operation to resolve the time discrepancy when the detection unit detects a communication error, a first condition is met which may cause a time discrepancy in the time measured by the measurement unit, and a second condition is met which may cause the communication error due to a time discrepancy. An information processing device characterized by having the following features.

2. The information processing apparatus according to claim 1, wherein the control unit does not perform the predetermined operation when a communication error is detected by the detection unit, or when the first condition is not met or the second condition is not met.

3. The information processing apparatus according to claim 1 or 2, wherein the control unit determines whether the first condition is met based on the specifications of the measurement unit or the surrounding environment.

4. The information processing apparatus according to claim 1 or 2, wherein the control unit determines that the first condition is met if time setting has not been performed after the device is started, if synchronization with a server that distributes time information has not been successful after the device is started, or if a predetermined amount of time has elapsed since time setting was performed or synchronization with a server that distributes time information was successful.

5. The control unit calculates an estimated value of the time difference measured by the measurement unit, and determines whether the first condition is met by comparing the estimated value with a threshold value. The information processing apparatus according to claim 1 or 2, further comprising a setting unit for setting the threshold.

6. The information processing apparatus according to claim 1 or 2, wherein the control unit determines that the second condition is met when the communication interface in which the communication error occurred is the first communication interface, when the communication interface in which the communication error occurred is not the second communication interface, when the communication error occurred during authentication by a specific user management method, or when the communication error occurred during file sharing by specific hardware or software.

7. The information processing apparatus according to claim 1 or 2, wherein the control unit performs the predetermined operation of notifying that a time difference may be included as a cause of the communication error, or notifying the user to set the time.

8. The information processing apparatus according to claim 1 or 2, wherein, if a server for distributing time information is not configured, or if communication with an external network is possible, the control unit performs the predetermined action of issuing a notification prompting the configuration of a server for distributing time information.

9. The aforementioned information processing device is an image reading device, The information processing apparatus according to claim 1 or 2, wherein the control unit, as a predetermined operation, acquires time information from a device to which the image generated by the information processing apparatus is transmitted, or from another image reading device.

10. The measurement unit measures the time, The communications unit communicates with external devices. Detects communication errors with external devices, If a first condition is met in which a communication error is detected and a time discrepancy may occur in the time measured by the measurement unit, and a second condition is met in which the cause of the communication error may be a time discrepancy, then a predetermined operation to resolve the time discrepancy is performed. An information processing method characterized by the following:

11. A control program for an information processing device having a measuring unit for measuring time and a communication unit capable of communicating with external devices, Detects communication errors with external devices, If a first condition is met in which a communication error is detected and a time discrepancy may occur in the time measured by the measurement unit, and a second condition is met in which the cause of the communication error may be a time discrepancy, then a predetermined operation to resolve the time discrepancy is performed. A control program characterized by causing the information processing device to perform the following action.
