IMAGE PICKUP DEVICE AND PROGRAM

摘要

An image capture device includes: a first and second optical system including a first and second focus lens, respectively; a first image sensor that outputs an electrical signal representing a subject image that has been produced through the first focus lens; a second image sensor that outputs an electrical signal representing a subject image produced through the second focus lens; and a drive controller that moves the first and second focus lenses along their optical axes. The drive controller has the second focus lens follow a position determined by a position of the first focus lens until the first focus lens reaches a position close to in-focus position, and then moves the first and second focus lenses to in-focus positions independently of each other once the first focus lens has reached the position close to the in-focus position.

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 an optical axis of the first optical system and the second focus lens along an optical axis of the second optical system, the drive controller being configured to (i) have the second focus lens follow a position determined by a position of the first focus lens until the first focus lens reaches a position close to an in-focus position, 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 close to the in-focus position.
