Abstract
After scan conditions are determined by the pre-scan, a temperature of a focus lens unit is measured. When the difference between the measured temperature and a set temperature data stored in a RAM is less than 4° C., a focus position is calculated based on set focus position data in the RAM and temperature correction data which is decided according to the temperature difference. When the temperature difference is 4° C. or more, a focus search operation is carried out to detect the focus position. Focus position data and temperature data, obtained by the focus search operation, are written in the RAM as set focus position data and set temperature data. It is possible to omit the focus search operation if temperature fluctuation is small.
