Abstract: Publisher Summary This chapter elaborates the electron optics of a photoconductive image converter. A demountable system was built in order to investigate the electron optics of the photoconductive image converter. In this system, a weak magnetic lens is included which provides a means of magnification control. An important practical consideration is the choice of a suitable photoconductive layer. The layer surface needs to be very smooth, otherwise the effect of surface topography appears in the output image. It should have a thickness of the order of one micron and its resistivity should be not less than l011 Ωcm. These requirements appear to be fulfilled by a mixture of selenium and bismuth in the proportion 95% Se, 5% Bi by atomic weight. Using the demountable system and evaporated photoconductive layers, it was possible to obtain image conversion in the infrared, the filter employed at the input having a narrow pass band centered on 9600 Ǻ. The image obtained using a test grid pattern shows the predicted form of distortion. The buildup of insulating contamination because of the poor vacuum interferes with the proper functioning of the layer, and it seems likely that prolonged tests of the image converter require a sealed-off system.

26 Jul 2005TL;DR: In this article, a digital imaging apparatus consisting of a capture part for consecutively capturing a plurality of images, an image information detection part for detecting image information regarding the plurality of image output from the capture part, and a panorama image generation part for converting the images based on the image conversion information is presented.
Abstract: A digital imaging apparatus for creating a panorama image and a method thereof, wherein the digital imaging apparatus comprises a capture part for consecutively capturing a plurality of images, an image information detection part for detecting image information regarding the plurality of images output from the capture part, respectively, and a panorama image generation part for converting the plurality of images based on the image conversion information. The image conversion information is determined by selecting one set of the plurality of image information output from the image information detection part, converting the image information regarding the plurality of images output from the capture part using the selected image information, and combining the converted images, thereby creating a natural-looking panorama image.

TL;DR: In this article, a method and a device for omnidirectionally stitching videos in the form of an aerial view and detecting a moving body around a facility, based on multiple cameras, is presented.
Abstract: Disclosed are a method and a device for omnidirectionally stitching videos in the form of an aerial view and detecting a moving body around a facility, based on multiple cameras. The method comprises the steps of: (a) receiving an individual image acquired from each of a plurality of fixed cameras disposed around the outer periphery of a facility at intervals such that the image acquisition direction faces the ground around the facility; and (b) stitching the received individual images to convert the stitched images to an aerial-view image. Each of the plurality of fixed cameras has an image analysis algorithm detecting a moving body from the individual images. When at least one of the plurality of fixed cameras detects the moving body from the individual images by the image analysis algorithm, a server receives moving body information on the moving body together with the individual images in step (a) and performs aerial-view image conversion by labeling and overlaying the moving body by using the moving body information in step (b). Thus, the circumstances surrounding the facility can be grasped from the aerial view at a glance.
