Abstract
The invention relates to a camera. The inclination angles of a camera lens and an imaging target surface are adjusted by adjusting the inclination of a charge coupled device (CCD) printed board or the camera lens. The inclination of the camera lens is adjusted by adjusting a front cover of the camera or arranging an adapter ring with an adjustable inclination angle. The inclination of the CCD printed board is adjusted by forming screw holes at four corners of the CCD printed board and arranging a spring-equipped screw and an adjusting screw in a housing case. The inclination of the front cover of the camera is adjusted by forming screw holes at four corners of the front cover of the camera, connecting the spring-equipped screw with the housing case through a screw hole and adjusting the spring-equipped screw. The adapter ring with an adjustable inclination angle consists of a camera end adjusting plate, a lens end adjusting plate, a telescopic middle connector and an adjusting screw. The two ends of the adapter ring are connected with the camera and the lens through interfaces respectively. Four corners of the two adjusting plates are provided with adjusting bolts for connecting the adapter ring into a whole. The inclination of the lens is changed by the adjusting bolts. Through the method, clear and visible imaging can be realized when different inclination angles are formed between a shooting target and the imaging target surface.
