摘要： The invention relates to electronic equipment. The equipment includes camera means for forming data from an object located in the imaging direction, in which case the said camera means include at least two camera units (CAM1, CAM2) and data-processing means, which are arranged to process the data formed using the camera means, in a manner corresponding to the currently selected imaging mode, to form image information. In the equipment, the mutual position of the camera units (CAM1, CAM2) relative to each other is arranged to be altered to correspond to the current imaging mode.

摘要： A display device (500) comprises a micro-display (22) and imaging optics (24) to transmit a light beam (BO), and a diffractive beam expander (10) having an output grating (16). The combination of said micro-display (22) and said imaging optics (24) is together adapted to form a virtual image (710) which is observable through the perimeter (15) of said output grating (16) when said diffractive beam expander (10) is positioned to at least partially intercept said light beam (BO). The combination of said micro-display (22) and said imaging optics (24) may also be adapted to project said light beam (BO) onto an external screen (600) in order to display a real image (610). The display device (500) may comprise a movable optical component (10, 380) to switch the device (500) from a virtual display mode to a projecting mode.

摘要： A portable device (1) having an optical engine (16) adapted to form an image from an image source in four different modes to allow a viewer to view the image. The image source is a microdisplay device, which can be reflective (32), transmissive (32’) or emissive (32’’). The display modes include a near-eye display (NED) mode, a near projection display (NPD) mode, a Window mode that provides a virtual image to a viewer at a distance, and a projection display mode that projects an image on a surface at a distance. The portable device has an internal light source (20) to provide illumination to the image source for the first three modes. The portable device is further adapted to receive the light output from an external light source for use with the fourth mode.

摘要： A light beam is used to illuminate a spot on a lens element which is shifted along the optical axis of an imaging system for auto-focus or optical zoom purposes. The light beam is arranged such that the reflected light beam from the lens element encounters a spot on the image sensor. The spot location on the image sensor is determined by a signal processor. As the lens element is shifted along the optical axis, the spot location changes accordingly. Based on the moving distance of the spot, the signal processor determines the shifting distance of the lens element and hence the position of the lens element. Based on the shifting distance of the lens element, a control module is used to adjust the lens position along the optical axis to achieve the desired focusing or zooming effects.
