摘要 |
An imaging apparatus achieves a high-speed automatic focus operation and a reduction in power consumption and prevents a miss focus due to an erroneous determination. The imaging apparatus has an automatic focus function, which detects a current position of a focal lens. A limited range near the detected current position of the focal lens is designated as a focus range. A movable range of the focal lens is changed in accordance with the designated focus range. |
