A face image processing device, includes: an image coordinate system coordinate value derivation unit detecting an x-coordinate value and a y-coordinate value in an image coordinate system at a feature point of an organ of a face of a person in an image, and estimating a z-coordinate value, so as to derive three-dimensional coordinate values in the image coordinate system; a camera coordinate system coordinate value derivation unit deriving three-dimensional coordinate values in a camera coordinate system from the three-dimensional coordinate values in the image coordinate system derived by the image coordinate system coordinate value derivation unit; and a parameter derivation unit applying the three-dimensional coordinate values in the camera coordinate system derived by the camera coordinate system coordinate value derivation unit to a predetermined three-dimensional face shape model to derive a model parameter of the three-dimensional face shape model in the camera coordinate system.

Face image processing device and face image processing program

An occupant monitoring device includes: an acquisition unit that acquires a captured image obtained by imaging a region in which there is a probability that a face of an occupant is present in a vehicle; a determination unit that determines whether the captured image acquired by the acquisition unit corresponds to a first image including the face a part of which is hidden by an accessory or a second image including the face a part of which is hidden by a non-accessory object other than the accessory; and a processing unit that detects face information regarding the face of the occupant based on the captured image in different modes according to a determination result in the determination unit, and monitors a state change of the face of the occupant based on a detection result.

Occupant monitoring device, occupant monitoring method, and occupant monitoring program

An occupant modeling device includes: an acquisition section acquiring an image by imaging a region where there is a probability that a face of an occupant is present; a model fitting section generating a model of the face based on a first image acquired by the acquisition section; a tracking section adapting the model to a second image acquired after the first image; a determination section determining correctness of a facial part position included in the second image to which the model is adapted, by using learned information obtained through learning based on correct information and incorrect information regarding the facial part position; and a processing section determining whether a process in the tracking section is to be continuously executed or a process in the model fitting section is to be executed again according to a determination result in the determination section.

An occupant monitoring device includes: an acquisition unit that acquires a captured image obtained by imaging a region in which there is a probability that a face of an occupant is present in a vehicle; a determination unit that determines whether the captured image acquired by the acquisition unit corresponds to at least a first image not including a feature portion of the face of the occupant but including at least a part of a body of the occupant or a second image not including the body of the occupant; and a processing unit that monitors a state change of the face of the occupant based on the captured image, and switches whether or not an occupant parameter set for monitoring the state change of the face of the occupant is to be reset according to a determination result in the determination unit.

An input device, wherein the screen () of a display device () is divided into two regions, a region (A) and a region (A), and the icon switch displayed in the region including the position of an invisible pointer (P') is selected. Thus, one of an icon switch () and an icon switch () that are displayed on the screen () is selected at any time. Consequently, the user will no longer have to watch the screen carefully and perform an operation for moving an instruction marker such as a visible pointer to a desired icon switch, for example as in conventional devices. Accordingly, the user can enter a desired instruction in a short time by selecting a desired icon switch in a short time.
