Abstract: A video control device includes a processor and a memory including a program that, when executed, causes the processor to perform operations including: obtaining a position of a vehicle determined by a satellite positioning system; obtaining an estimated position of the vehicle estimated based on dead reckoning; estimating a deviation in an orientation of the vehicle, based on the position of the vehicle determined by the satellite positioning system and the estimated position of the vehicle estimated based on the dead reckoning; calculating an estimated orientation of the vehicle, based on the deviation in the orientation of the vehicle estimated; and outputting the estimated orientation of the vehicle to a video display device that displays information which is based on the orientation of the vehicle.

Abstract: An image display system includes: an image projection unit that projects and displays an image on a display target for a moving body; a posture angle calculation unit that calculates a posture angle for the moving body on the basis of chronological data for acceleration detection values for the acceleration of the moving body in a prescribed time period; and a display control unit that controls the display position at which the image is projected and displayed on the display target, in accordance with the posture angle calculated by the posture angle calculation unit. The acceleration detection values include bi-directional components. The posture angle calculation unit excludes acceleration detection values from the chronological data used when calculating the posture angle, said acceleration detection values being included in an exclusion time period which has a ratio for the bidirectional components, in the prescribed time period, that is outside a prescribed range.

Abstract: The present invention provides a Fresnel lens that can reduce generation of concentric stray light. The Fresnel lens includes a sawtooth corrugated face that is formed by alternately disposing a first face inclined relative to optical axis A and a second face substantially parallel to optical axis A, and a light shielding mask is formed at a position corresponding to the second face.
