    • A measuring unit (10) obtains measurement data of an object measured on the basis of a signal from a GPS satellite and angular velocity of an object output from an angular velocity sensor (26). An offset value computing unit (28) estimates a running condition of the object. The offset value computing unit (28) sequentially derives temporary offset values while changing combination of the measurement data and the angular velocity in accordance with the estimated running condition of the object and, after that, executes statistical process on the temporary offset values, thereby deriving an offset value. An angular velocity conversion coefficient computing unit (30) sequentially derives temporary angular velocity conversion coefficients on the basis of the measurement data and the angular velocity and, after that, executes statistical process on the temporary angular velocity conversion coefficients, thereby deriving an angular velocity conversion coefficient.

    • In a video camera (10), air outlet holes (12b) and air inlet holes (12c) are disposed in a panel-facing surface (12a) of a camera body (12). A liquid crystal panel unit (14) is disposed movably between a first position in which a first face (14a) faces the panel-facing surface (12a) of the camera body (12) and a second position in which a second face (14b) faces the panel-facing surface (12a). When the liquid crystal panel unit (14) is in the first position, the first face (14a) is so formed as to cover the air outlet holes (12b) and the air inlet holes (12c). The second surface of the liquid crystal panel unit (14) is formed so that the air outlet holes (12b) and the air inlet holes (12c) are open to the exterior when the liquid crystal panel unit (14) is in the second position.

    • An optical system capable of outputting hi-contrast images and multi-primary color or 3-dimensional images is provided. Light in primary colors RGB modulated in a first modulation optical system is transmitted through a relay lens 36 and further divided into a P-polarized light and an S-polarized light by a PS separation wire grid 37. The S-polarized light is transmitted through a wavelength spectral filter 39 to select red/geen/blue light components R1, G1, B1 of 615, 515, 450 nm in wavelength, which are then modulated by a Y1 device 44. The P-polarized light is transmitted through a wavelength spectral filter 46 to select red/geen/blue light components R2, G2, B2 of 650, 550, 475 nm in wavelength, which are then modulated by a Y2 device 51, The 3-primary color lights modulated by the Y1/Y2 devices 44, 51 are combined with each other at a PS composite wire grid 55 to project a synthetic light on a screen.
