A vision display system for a vehicle includes a rear backup camera, a driver side camera, a passenger side camera, a front camera, and a display system including a video display screen. Rear backup video images derived from image data captured by the rear backup camera may be displayed by the video display screen for no more than ten seconds after shifting of the vehicle transmission of the vehicle out of reverse gear. Upon the engine of the vehicle being first started after initial ignition on of the vehicle, priority may be given to display by the video display screen of rear backup video images. Within two seconds after shifting of the vehicle transmission of the vehicle into reverse gear, rear backup video images may be displayed by the video display screen.

A mark irradiation unit (130) irradiates an object with a mark. An image capture unit (140) captures an image of the object, and generates image data. Then, an image capture area data generation unit recognizes a position of the mark in the object, and cuts out image capture area data which is a part of the image data on the basis of the mark. For this reason, the mark irradiation unit (130) irradiates the object with the mark, and thus even when a positioning symbol is not printed on the object to be stored as the image data, only a necessary portion in the image data is cut out.

A multifunctional sky camera system and techniques for the use thereof for total sky imaging and spectral irradiance/radiance measurement are provided. In one aspect, a sky camera system is provided. The sky camera system includes an objective lens having a field of view of greater than about 170 degrees; a spatial light modulator at an image plane of the objective lens, wherein the spatial light modulator is configured to attenuate light from objects in images captured by the objective lens; a semiconductor image sensor; and one or more relay lens configured to project the images from the spatial light modulator to the semiconductor image sensor. Techniques for use of the one or more of the sky camera systems for optical flow based cloud tracking and three-dimensional cloud analysis are also provided.

A device for assisting the piloting of a rotorcraft in order to pilot a rotorcraft during an approach stage preceding a stage of landing on a rotorcraft landing area. Such a device includes in particular a camera for taking a plurality of images of the environment of the rotorcraft along a line of sight, looking at least along a forward direction Dx of the rotorcraft, and processor means for identifying in at least one image from among said plurality of images at least one looked-for landing area.

A lifting hook bias angle monitoring apparatus, a vertical hoisting monitoring apparatus, and a mobile crane. One method is that a lifting hook assembly serially connects connecting plates (b3) provided with hinge connection shafts (b2, b4) at two ends to a movable pulley component (b1) which bears a pulling force and a lifting hook component (b7) which bears a pulling force, and is also provided with a biaxial inclinometer (b9) on a platform surface (b8) of the connecting plates (b3) which is perpendicular to a lifting force line of action of the lifting pulley component, so as to detect a real-time lifting hook bias angle, and accordingly be developed into a mobile crane having a vertical hoisting monitoring function.

An electronic device has multiple cameras and displays a digital viewfinder user interface for previewing visual information provided by the cameras. The multiple cameras may have different properties such as focal lengths. When a single digital viewfinder is provided, the user interface allows zooming over a zoom range that includes the respective zoom ranges of both cameras. The zoom setting to determine which camera provides visual information to the viewfinder and which camera is used to capture visual information. The user interface also allows the simultaneous display of content provided by different cameras at the same time. When two digital viewfinders are provided, the user interface allows zooming, freezing, and panning of one digital viewfinder independently of the other. The device allows storing of a composite images and/or videos using both digital viewfinders and corresponding cameras.

A vehicular rear backup system includes a rear backup digital camera disposed at a vehicle and a display device having a video display screen disposed in an interior cabin of the vehicle and viewable by the driver of the vehicle. Rear backup video images that are derived from image data captured by the rear backup digital camera are displayed on the video display screen no later than two seconds after the driver of the vehicle first changes propulsion of the vehicle during a new ignition cycle to reverse mode to commence a first backup event. Until the first backup event is completed, the video display screen displays rear backup video images. During a backup event of the vehicle, image data captured by the rear backup digital camera is provided to and is processed by an image processor of the system to detect presence of an object rearward of the vehicle.

A system including a motorized base unit with a smart device mount for automatically orienting the smart device camera toward a moving target to track the moving target and take pictures or video. The target (e.g., a child playing soccer) wears a tracking tag comprising a GPS chip and transmitter packaged inside an athletic pad. The base unit includes a motorized mast for mounting a smart device. The base unit receives the transmitted GPS data, calculates updated pointing angle and angular velocity for the smart phone based on update location information from the remote tag sensor, calculates the correct angle that the smart phone should be pointed at, translates the new pointing directions to a control signal that turns the mast, which in turn causes the smart device camera to “follow” or track the target.
