Claim Text:
1. An image capture device, comprising: a first optical system including a first focus lens; a second optical system including a second focus lens; a first image sensor configured to output an electrical signal representing a subject image that has been produced through the first focus lens; a second image sensor configured to output an electrical signal representing a subject image that has been produced through the second focus lens; and a drive controller configured to move the first focus lens along a first optical axis of the first optical system and the second focus lens along a second optical axis of the second optical system, the drive controller being configured to (i) move the second focus lens to a position on the second optical axis determined by a current position of the first focus lens on the first optical axis until the first focus lens reaches a position within a predetermined threshold of an in-focus position, whereby the second focus lens moves relative to the first focus lens such that a spacing between the second focus lens and the first focus lens changes when moving the second focus lens to the position on the second optical axis determined by the current position of the first focus lens, and then (ii) move the first and second focus lenses to in-focus positions independently of each other once the first focus lens has reached the position within the predetermined threshold of the in-focus position.
