20120044327 | DEVICE FOR ACQUIRING STEREO IMAGE - Disclosed is an inexpensive device for acquiring a stereo image, in which base data is generated and recorded from an image captured by a base camera according to a first frame rate, and reference data is generated and recorded from an image captured by a reference camera according to a second frame rate which is the same as the first frame rate or lower than the first frame rate, the second frame rate dynamically determined depending on the status of a vehicle or the periphery thereof during the image-capturing, and thereby the device can record a stereo image with high image quality and acquire highly accurate distance information, and can also eliminate the need for an expensive storage medium or an expensive electronic circuit. | 2012-02-23 |
20120044328 | IMAGE CAPTURE USING LUMINANCE AND CHROMINANCE SENSORS - Methods and apparatuses disclosed herein relate to image sensing devices. One embodiment may take the form of an image sensing device that includes a first image sensor for capturing a luminance image, a second image sensor for capturing a first chrominance, and a third image sensor for capturing a second chrominance image. The image sensing device may further include an image processing module for combining the luminance image captured by the first image sensor, the first chrominance image captured by the second image sensor, and the second chrominance image captured by the third image sensor, to form a composite image. | 2012-02-23 |
20120044329 | METHODS, APPARATUSES, SYSTEMS, AND COMPUTER PROGRAM PRODUCTS FOR HIGH DYNAMIC RANGE IMAGING - High dynamic range imaging includes creating a high dynamic range image file for a subject image captured from a first angle. The high dynamic range image file is created by an image capturing device and is stored on the image capturing device. High dynamic range imaging also includes receiving, at the image capturing device over a communications network, a second high dynamic range image file for the subject image captured from a second angle. The second high dynamic range image file is subject to an authorization requirement. High dynamic range imaging further includes creating, by the image capturing device, a composite high dynamic range image file by combining elements of both of the high dynamic range image files, and generating, by the first image capturing device, a three-dimensional high dynamic range image from the composite high dynamic range image file. | 2012-02-23 |
