IMAGE CAPTURING DEVICE, OPERATOR MONITORING DEVICE, METHOD FOR MEASURING DISTANCE TO FACE, AND PROGRAM

摘要

An imaging device (1) includes a camera unit (3) that captures images of the same object, respectively, using two optical systems, a face part detection unit (9) that detects a plurality of face parts composing a face included in each of the images captured by the camera unit (3), a face part luminance calculation unit (10) that calculates luminance of the detected plurality of face parts, and an exposure control value determination unit (12) that determines an exposure control value of the camera unit (3) based on the luminance of the plurality of face parts. A distance measurement unit (17) in the imaging device (1) measures distances to the face parts based on the images captured by the camera unit (3) using the exposure control value. Thus, the imaging device (1) can measure the distances to the face parts with high accuracy.
