IMAGE PROCESSOR, DATA TRANSMITTER POWER REDUCTION DETECTION WARNING METHOD BY THE PROCESSOR, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image processor, etc. capable of allowing a user to reliably recognize the reduction of a remaining capacity in the power source of a data transmitter by receiving a signal that has been output from the data transmitter mounted on a user and transmitted with the body of the user as a communication route and authenticating the user in log-in.

SOLUTION: An image processor includes: reception means 192 for receiving a signal that has been output from a data transmitter 4 mounted on a user and transmitted with the body of the user as a communication route; S/N ratio detection means 194 for detecting a S/N ratio being the ratio of the level of a signal received from the data transmitter 4 to a noise level whenever user authentication is performed in log-in; preservation means 15 arranged inside or outside the own processor and preserving the detected S/N ratio as a log; prediction means 11 for predicting timing for disabling communication with the data transmitter on the basis of the change of the preserved S/N ratio; and warning reporting means 172 for reporting a warning when the predicted timing for disabling communication is coming.
