Embodiment Construction
[0023] Hereinafter, various embodiments of the present invention as the best mode for carrying out the present invention will be described with reference to the accompanying drawings. The invention relates to a panoramic imaging device. It should be understood that the embodiments described herein are not intended to limit or cover the entire scope of the invention. Note that throughout the drawings, like parts are denoted by like reference numerals, characters or symbols.
[0024] Referring to FIGS. 1 to 9 , a panoramic imaging device 1 according to an embodiment of the present invention will be described. As shown in Fig. 1, the panoramic imaging device 1 of the embodiment of the present invention includes: an optical lens system 2, which is used to collect the light entering it with an acquisition angle (image capture angle) of 120° (about 120°), and then An image is formed on a plane; an XY address (address) type solid-state imaging part 3 (hereinafter simply referred to...

A panoramic imaging device (1) comprises: a lens array (11) with lenses (8) in a matrix; an imaging element (3); and prisms (12) for mirror-reflecting lights entering in left / right ranges in a capture range to guide them to side lenses in left / right columns. Light in a front range is inverted up / down by center lenses and formed as up / down inverted images on the imaging element (3). Lights in the left / right ranges are inverted up / down and left / right by the prisms with the side lenses and formed as up / down and left / right inverted images on the imaging element. The images in the left / right ranges are read in one direction. The images in the front range are read in an opposite direction. The read images are combined as is, without inverting the images, to reproduce a panoramic image. This can prevent the entire device from becoming large in volume, and imaging processing from becoming complex.
Description
technical field [0001] The invention relates to a panoramic imaging device. Background technique [0002] Panoramic imaging devices are known that use wide-angle optical systems such as fish-eye lenses to collect light rays entering within a wide acquisition angle. However, a panoramic image captured by such an imaging device is likely to have a large distortion, and therefore, in order to reproduce a normal panoramic image, complex distortion correction processing is required to digitally process the captured image. On the other hand, advances have been made in techniques for converting acquired images into digital information and then processing them. In order to produce a panoramic image in a wide acquisition angle, various imaging devices have been developed using this technique, in which the acquisition angle is divided into a plurality of predetermined continuous The images are combined to reproduce a panoramic image. Hereinafter, such a panoramic imaging device tha...
