20120183011 | TEMPERATURE DETECTING DEVICE, ELECTRO-OPTIC DEVICE AND ELECTRONIC APPARATUS - A control unit sets a time interval for measuring a temperature of a liquid crystal panel as a first time interval (1 second), and thereafter measures the temperature of the liquid crystal panel each time the first time interval elapses. When the temperature of the liquid crystal panel is stabilized, the control unit sets a time interval for measuring the temperature of the liquid crystal panel as a second time interval (5 seconds). The control unit measures the temperature of the liquid crystal panel each time the second time interval elapses. Moreover, if an operation to change the amount of light reaching the liquid crystal panel is performed, the control unit restores the time interval for measuring the temperature of the liquid crystal panel to the first time interval. | 07-19-2012 |
