Title:
IMAGE CAPTURE DEVICE AND IMAGE CAPTURE METHOD
Document Type and Number:
WIPO Patent Application WO/2011/158498
Kind Code:
A1
Abstract:
Disclosed is an image capture device that generates a distance map to a photographic subject from a photographic image, with high precision. Three images are photographed with a sensor drive unit (12) and a sensor drive controller unit (13), which move an image sensor (11) in the optical axis direction: photographic images (A, C) that are respectively focused on the near-end side and the far-end side of the photographic subject, and an image (B) that is photographed while sweeping the image sensor from the near-end side to the far-end side. An omnifocal image (D) is generated by an omnifocal image generator unit (15) from the sweep image (B); a blur quantity in each component region of the image (A) and the image (B) is computed by a blur quantity computation unit (16), carrying out a deconvolution process with an image of a region corresponding to the omnifocal image (D); and the distance from the device to the photographic subject in each image region, i.e., a distance map, is generated by a distance map generator unit (17) from the blur quantity of the regions corresponding to the near-end image (A) and the far-end image (C) and optical coefficients of the image capture device, including the focal length of the lens.
