Abstract
An image capture device assembly includes a light source that emits a reference light pattern, an image capture device, and a control device that controls the light source and the image capture device. The light source emits the reference light pattern to a subject with high brightness and low brightness, respectively, under the control of the control device. The image capture device captures an image of the reference light pattern and the subject in a high brightness irradiation state and outputs a first image signal to the control device. The image capture device captures an image of at least the subject in a low brightness irradiation state and outputs a second image signal to the control device. The control device generates a reference light pattern image signal from a difference between the first image signal and the second image signal.
