Provided are an image processing device and an image processing method for acquiring a consciousness level at which a driver recognizes a surrounding environment on the basis of an image of the driver picked up by an in-vehicle camera. An image of an eyelips is picked up by an in-vehicle camera 100 at low resolution and eye positions grasped in the image analysis are corrected for each frame while being subjected to local high-speed processing in parallel, whereby the tracking of the saccade among eyeball movement is realized. That is, active local high-speed eye tracking is performed only on a capture frame 102 in an image picked up by the in-vehicle camera 100, whereby it becomes possible to monitor the saccade of the eye movement without causing an attachment load.
