PURPOSE: To accurately perform the correction of a measured value of light measurement for exposure control and distance measurement for focus control by a temperature. CONSTITUTION: A period of time from the current-carrying start to the current- carrying finish of a diode 14 as a temperature sensor is measured by a timer of a microcomputer 1 by utilizing that the voltage of the diode 14 is in proportion to an absolute temperature when a current flowing thereinto is constant, a temperature correction quantity is sought on the basis of the measuring time, the output of the diode 14 is corrected on the basis of the correction quantity and the outputs of a line sensor 9 as a distance measurement circuit and a light measurement circuit 3 are corrected. |
