A method for orienting a digital panoramic image obtained using at least one initial wide-angle image the image points of which are transferred into a three-dimensional coordinate system includes inserting an orientation mark into the initial image at the time of the exposure. The method further includes detecting the location of the orientation mark in the digital panoramic image, performed by an image analysis algorithm.

The invention provides a control method and a control device for an electronic device, the electronic device and a medium. The electronic device comprises a plurality of wide-angle cameras and a plurality of long-focus cameras. The control method comprises the following steps of determining distances between a target object and lenses of the long-focus cameras according to images collected by thewide-angle cameras respectively; controlling the lenses of the long-focus cameras to move towards a focusing position corresponding to the target object of the lenses to a preset position according tothe distances; and controlling the lenses of the long-focus cameras to move to the focusing position at the preset position in order to enable the long-focus cameras to focus. According to the control method in the embodiments of the invention, the distances between the target object and the lenses of the long-focus cameras are determined according to the images collected by the wide-angle cameras, the lenses of the long-focus cameras move to the preset position according to the distances, and the lenses of the long-focus cameras are controlled to move to the focusing position in order to enable the long-focus cameras to focus, so that the focusing time can be shortened, and the user experience can be improved.

In a digital camera, when the shutter is half-depressed, a controlling section 20 sequentially acquires current through-images imaged by an image acquiring section 10 which are wide-angle images imaged before zooming. Then, when a zoom operation is performed, the controlling section 20 holds a wide-angle image acquired at that point as a guidance image. Next, when the zoom magnification exceeds a predetermined magnification (for example, 3×), the controlling section 20 displays in a display section 25 the guidance image (wide-angle: low magnification) imaged before the zoom operation with a telephoto image imaged after the zoom operation. At the same time, a position corresponding to the current telephoto image is displayed to be identifiable within the guidance image. As a result, an imaging subject is easily confirmed when zooming is performed from wide-angle imaging to telephoto imaging.

The invention provides the virtuality to reality autonomous response technology, relates to synthesis of an image shot by a camera and a three-dimensional computer pattern in real time and aims to form a new TV program making system. The method comprises steps that 1, the position of a blue case coordinate center b (0, 0) is determined, a relative position relationship between an auxiliary camera shooting wide angle and a main camera is preset, and two adjacent images are inputted to virtuality and reality real-time interaction software; 2, the position of a target object b (x, y) is determined, an area A of the step 1 is taken as the foreground, an image of the target object is shot by an auxiliary camera in real time, displacement of the target object relative to a reference coordinate center b (0, 0) is calculated through an image processing system in real time, and the position coordinate b (x, y) of the target object taking a frame as a sampling unit is acquired; and 3, the three-dimensional rendering equipment is utilized for rendering, and the result is outputted.

Object images captured by a wide-angle camera are distorted due to the optical effects of the wide-angle lens. The disclosed innovations allow an automatic analysis on the corrected image distinguishing normal movement from an unusual event movement. The analysis is based on Markov Modeling on moving object trajectories and motion angles.

A method and apparatus is disclosed for providing special effects for wide-angle video images. The special effects include replacing a selected portion of a wide-angle video image with a predetermined image or an associated portion of a video image captured in a subsequent frame. Other special effects include image intensity scaling for wide-angle video images.

A wide-angle lens system is formed, sequentially from an object side, with a first group having a positive power, a second group having a negative power and a third group having a positive power, and at the time of focusing, only the second group is moved on an optical axis. The lens system satisfies conditional formulas of 0.3<BH1/T1<0.7 and 0.9<f3/f<1.8 (where BH1 is a distance from the final surface of the first group to a principal point position on the back side of the first group, T1 is a distance on the optical axis from a lens element surface of the first group closest to the side of the object to a lens element surface closest to the side of the image, f3 is the focal length of the third group and f is the focal length of the entire system).

A 3-D viewing system is disclosed that enables multiple operators to share a common objective element while readily adjusting the orientation of images that are displayed to one or more moveable display units. The orientation of images that are displayed at a movable display unit can be made to automatically depend on the position/orientation of the display unit. Thus, greater freedom in viewing postures is provided than previously available in 3-D viewing systems that share a common objective element, and each operator may view a 3-D image with proper perspective for his position/orientation. In order to reduce the number of optical components, the need to adjust optical components, and reduce costs, images from at least two different optical perspectives may be time-division multiplexed onto a single optical detecting device. Moreover, wide-angle, electronic color displays are disclosed which demodulate time-multiplexed image signals having two different parallaxes in a manner that dispenses with the need for wearing polarized glasses in order to experience a wide-angle, 3-D viewing experience. An electronic image display unit demultiplexes image data using left and right LED sets that are energized in sequence to emit up to three color light beams toward the left and right eyes of a viewer, at a frequency higher than 30 times per second. The light beams are then modulated with the image data for that color component using one or more high-speed, image modulators. Such modulators may be formed of transmissive or reflective liquid crystals in a known manner, or by an array of DMD's that are controlled in a binary fashion to reflect light for a given pixel within or outside an exit pupil of the display. If DMD's are used as the modulator, the duty cycle for a given pixel may be controlled in order to provide gradation of the display brightness for that pixel.
