Abstract: An automatic focus state detection device executes focus adjustment by taking environmental factors such as temperature and power source voltage into consideration. The temperature of the camera, the power source voltage of the battery in the camera, and the posture of the camera are detected. Then, lens driving times for six representative points of the driving lens distance are computed. A driving time table is produced, and the defocus amount is detected. Then, based on the updated driving time table, the lens driving time corresponding to the current defocus amount is computed. Finally, the timing for each sequential process from release to start of exposure is determined. In this manner, the driving time is computed by taking the temperature, the power source voltage, and the posture into consideration, and a more accurate estimation of the lens driving time is realized.
