Abstract: A laser light source 1 outputs a laser. A condenser lens 80 condenses the laser outputted from the laser light source 1, and outputs it to an optical fiber 8. The laser that propagates through the optical fiber 8 enters a light guide panel 2. The light guide panel 2 converts the inputted laser into a planar illumination light. The planar illumination light passes through a light passing control section 4 and illuminates a liquid crystal panel 7, which is a spatial modulation element that convert light into an image. The light passing control section 4 controls a scatter pattern during the passing of the laser individually in each predefined image area, by a control circuit 81. Consequently, an image area 5 in which a speckle noise is reduced and an image area 6 in which the speckle noise is generated, are formed on a liquid crystal panel 7.

Abstract: There is a need for improving the accuracy of estimating a gain error for an angular velocity sensor. An error estimation section and a correction section are provided as well as a gyroscope that detects an angular velocity of a vehicle. The error estimation section assumes the gain error of the gyroscope to be a state quantity and finds an estimated value for the gain error using a Kalman filter. Based on the gain error found by the error estimation section, the correction section corrects a gain correction amount used for gain correction of values detected by the gyroscope. The correction section corrects the gain correction amount dedicated to right turn based on the gain error found by the error estimation section when the vehicle is assumed to turn right. The correction section corrects the gain correction amount dedicated to left turn based on the gain error found by the error estimation section when the vehicle is assumed to turn left.
