摘要： The present invention relates to the field of panoramic still and motion photography. In a first embodiment, a camera apparatus for panoramic photography includes a first image sensor positioned to capture a first image. The first image sensor has a rolling-shutter readout arranged in portrait orientation. The camera apparatus also includes second image sensor positioned to capture a second image. The second image sensor has a rolling-shutter readout arranged in portrait orientation. Finally, the camera apparatus includes a controller configured to signal the second image sensor to start capturing the second image before the first image sensor finishes capturing the first image. At least a portion of the first image is in front of the second image relative to a forward direction of the camera apparatus.

摘要： Systems and methods of providing spatially dependent image exposure information to a user of a digital camera. The described approach is applicable to determination of image exposure quality in a digital camera system. In these applications an image is displayed in a first display mode wherein the exposure information is overlaid on the image or in a second display mode wherein the exposure information is eliminated or reduced and thus is less obstructive of the image. In the second display mode, a separate exposure warning optionally conveys a subset of the information displayed in the first display mode. The invention includes a user input operable to temporarily specify a change in the display of the image between the first mode and the second mode while an image is displayed, thus providing the user with direct control of the presence and duration of spatially dependent image exposure information.

摘要： A color-separation prism assembly comprises first, second and third prisms. The first and second prisms have entrance surfaces, exit surfaces, and partially-reflecting surfaces, wherein the entrance surface of the second prism is separated by an air gap from the partially-reflecting surface of the first prism. The third prism has an entrance surface and an exit surface, wherein the entrance surface of the third prism is adjacent to the partially-reflecting surface of the second prism. The first prism has a cut-out serving as a flare-stop stop, and providing relief so as to allow the entrance surface of the third prism to slide across a plane disposed over the cut-out into a volume defined by the cut-out. The plane is formed as an extension of the partially-reflecting surface of the first prism. An optical axis passes through the first, second and third prisms. The optical axis passes at normal angles through the entrance surface of the first prism, and the exit surfaces of the first, second and third prisms. The partially reflecting surfaces each have angles-of-incidence of less than 30° relative to the optical axis.

摘要： A statistical classifier utilizes combined output values to determine posterior probabilities for certain output classes. In the field of handwriting recognition, compound characters are factored into classes of base letter forms and diacritical marks. A separate output activation value is produced for each base letter form and each diacritical mark. Pairs of output values, comprised of one value for a base letter form and one value for a diacritical mark, are combined to produce a posterior probability for every possible compound character, without requiring a network output for each possible class.

摘要： A filter capable of having its damping and frequency parameters independently varied. The filter can be represented in either a digital or an analog computation network. The network comprises four multipliers for multiplying by a frequency term twice and a damping factor twice. In addition, the network comprises two unit delay blocks for temporarily storing previous signal input values for zeros or output values for poles. These stored values are used in computing subsequent outputs. The multipliers are configured with adders and subtractors to compute a next output value as a combination of a current input, a weight -2+2df+f.sup.2 --wd.sup.2 f.sup.2 times the most recent saved value and a weight 1-2df+wd.sup.2 f.sup.2 times the previous saved value. Moreover, unity gain at DC can be achieved.

摘要： An electronically variable active analog delay line utilizes cascaded differential transconductance amplifiers with integrating capacitors and negative feedback from the output to the input of each noninverting amplifier. The delay of each section may be controlled through a conductor having distributed resistance connected at distributed points to the transconductance control terminal of the amplifiers with a controllable voltage gradient between the two ends of the conductor. Signals may be coupled in and added to a propagating signal using capacitors, or transconductance amplifiers which may also be of the differential transconductance type, particularly when coupling signals from a second delay line having substantially the same propagation velocity. The differential transconductance amplifiers may be arranged in pairs, each pair with positive feedback from the output terminal of the second to the input terminal of the first amplifier of the pair through a third differential amplifier with positive feedback from its own output terminal. The transconductances of the cascaded amplifiers are controlled in each section to produce the desired time-constant (delay) of the section, and the transconductance of the positive feedback amplifier is controlled for stable operation and gain control of the section.

摘要： An imaging array provides a plurality of distinguishable bitmap images and comprises an array of sensor cells capable of sensing radiation. The cells are connected in a manner to form distinguishable bitmap images through a pattern of correspondence among the cells. Each bitmap image formed comprises a combination of one or more cells indicative of detecting an image pixel within a field of array cells that have been nonindicative of such detection. The pattern of correspondence may be one of inhibition of the operation of other cells in the array or one of indication of operation to other cells in the array. Various patterns of correspondence can be created among the cells creative of bitmap images. Bitmap images may consist of combinations of responsive cells within a field of nonresponsive cells in the array. For example, each bitmap image may comprise radiation responsive array cells that have sensed a sufficient quantity of radiation within a field of cells which have not sensed radiation or have been inhibited from sensing radiation. On the other hand, each bitmap image may comprise array cells that have not sensed a sufficient quantity of radiation within a field of cells that have sensed a sufficient quantity of radiation. An application of the imaging array is in an IC chip for a cursor control device or an "optical mouse" for use with an interactive display oriented computer system to provide movement for a visible cursor from position to position on a display screen of such a system.
