An exposure control device in a camera comprises power supply circuit means for producing a temperature signal representative of an amount proportional to the absolute temperature, means for producing a first digital data representative of the film speed, digital-analog converting means for producing a first analog output depending on the ambient temperature from the first digital data and the temperature signal, photometering means having means for producing a second analog output corresponding to the brightness of an object to be photographed and means for adding the second analog output to the first analog output and preparing a photometering output, analog-digital converting means for preparing a second digital data independent on the ambient temperature from the temperature signal and the photometering output, and means for determining the exposure in accordance with the second digital data.
