1. An electronic apparatus comprising:
a plurality of thermometers that detect temperatures at a plurality of positions in the electronic apparatus;
a CPU; and
a memory which stores a program which, when executed by the CPU, causes the electronic apparatus to function as:
a control unit that displays, on a display, information relating to a time period until one of the plurality of temperatures detected by the plurality of thermometers reaches a threshold temperature, and performs control to restrict an operation of the electronic apparatus in a case where one of the plurality of temperatures detected by the plurality of thermometers has reached the threshold temperature,
wherein
the plurality of thermometers include a thermometer that detects a temperature of a heat source included in the electronic apparatus, and a thermometer that detects a temperature of an outer casing of the electronic apparatus,
the control unit performs control to obtain a first difference between the temperature of the heat source and a threshold temperature for the temperature of the heat source and a second difference between the temperature of the outer casing and a threshold temperature for the temperature of the outer casing, correct the first difference based on temperature increase characteristics of the heat source, correct the second difference based on temperature increase characteristics of the outer casing, and display the information based on the corrected first difference or the corrected second difference,
wherein the control unit performs control to
correct the first difference by multiplying the first difference by a first correction value based on the temperature increase characteristics of the heat source, and correct the second difference by multiplying the second difference by a second correction value based on the temperature increase characteristics of the outer casing, and
control the display of the information based on one of the corrected first difference and second difference that has a smaller value than the other, and on a predetermined control threshold, and
wherein the information includes a plurality of segments indicating a level until one of the plurality of temperatures detected by the plurality of thermometers reaches a threshold temperature,
a plurality of values are set as the predetermined control threshold in accordance with the number of segments to be displayed, and
the control unit displays the number of segments corresponding to the predetermined control threshold.
