Apparatus and method for blocking incident rays from entering an interior cabin of vehicle

A method for blocking incident rays to the inside of a vehicle, comprising:

• storing, on a memory within a control unit, 3D positional coordinate values of windshield glass and a driver's seat side glass in a control unit;
• photographing, by an imaging device, a hand area and an eye area of a driver when the driver raises a hand to block light rays incident in a driver's seat;
• acquiring, by the control unit, an extension line which connects an eye to a hand in the photograph by deducing 3D positional coordinate values of the hand area and the eye area photographed by the imaging device and acquire a point where an end portion of the extension line meets the windshield glass or the driver's seat side glass;
• and
• in response to the driver raided the hand to block light rays incident to the driver's seat, blocking or weakening the rays incident in the driver's seat by blocking the point where the extension line meets the windshield glass or the driver's seat side glass via a ray blocking mechanism.

A non-transitory computer readable medium containing program instructions executed by a control unit, the computer readable medium comprising:

• program instructions that store 3D positional coordinate values of windshield glass and a driver's seat side glass in a control unit;
• program instructions that control an imaging device to photograph a hand area and an eye area of a driver when the driver raises a hand to block light rays incident in a driver's seat;
• program instructions that acquire an extension line which connects an eye to a hand in the photograph by deducing 3D positional coordinate values of the hand area and the eye area photographed by the imaging device;
• program instructions that acquire a point where an end portion of the extension line meets the windshield glass or the driver's seat side glass;
• and
• program instructions that in response to determining that the driver raised the hand to block light rays incident to the driver's seat, apply an operating signal to a ray blocking mechanism to block light rays incident in the driver's seat at a point where the extension line meets the windshield glass or the driver's seat side glass.
