Summary: | For preventing frequent use of auto-focus control and also for acquiring stable in-focus positions for target-objects, this invention comprises system control section 60 having a second mode to drive magnification adjustment lens 11 or focus adjustment lens 12 upon a user command, and a third mode to transition to a first mode under pre-determined conditions in the second mode, and to set in-focus states of a lens group, wherein system control section 60 stores a reference target-object distance in reference target-object distance storage section 43 when focus adjustment lens 12 is driven by user commands in the second mode, drives focus adjustment lens 12 not based on a current target-object distance but the lens in-focus trajectory data to retain the reference target-object distance when the magnification adjustment lens 11 is driven by user commands, and re-transitions to the second mode without updating the reference target-object distance, after the third mode. |
