Imaging apparatus performing auto focusing function with plurality of band pass filters and auto focusing method applied to the same |
摘要 |
An imaging apparatus and an auto focusing method are provided. A plurality of focus signal values are calculated for a plurality of frequency bands of a captured image signal. An amount of defocus of a focus lens is calculated based on focus signal values calculated for two positions. A position of the focus lens is controlled depending on the calculated amount of defocus. Thereby, the imaging apparatus can detect a focus at higher speed. |
