Abstract

An image detection device includes: a variable focal length lens whose focal length is periodically changed in response to a drive signal that is periodic; an illuminator configured to illuminate a measurement target; an image detector configured to detect an image of the measurement target through the variable focal length lens; a drive controller configured to output the drive signal to the variable focal length lens; a light-emission controller configured to output a light-emission signal, which is in synchronization with the drive signal, to the illuminator; an oscillation sensor configured to detect oscillation information of the variable focal length lens; and a synchronous controller configured to adjust an output timing of the light-emission signal based on the oscillation information.
