Patent number: 9094581Abstract: An imaging device is provided that includes an imaging processor, a distance information detector, an outline-component maximum image detector, and a distance information correcting processor. The imaging processor captures a plurality of secondary images of the same object at different lens positions. The distance information detector detects distance information of the objects captured in each area of an image based on the sum of outline components in each of the areas in each of the secondary images. The outline-component maximum image detector calculates the sum of outline components for each of the secondary images and detects an image with the maximum sum. The distance information correcting processor replaces distance information of a target area, where the sum of outline components is less than a threshold value, with distance information of the image with the maximum sum.Type: GrantFiled: August 10, 2012Date of Patent: July 28, 2015Assignee: PENTAX RICOH IMAGING COMPANY, LTD.Inventor: Hiroyasu Uehara

Patent number: 8885091Abstract: An imaging device is provided that comprises an imaging processor, a distance information detector, a primary image capturing processor and an image processor. The imaging processor captures a plurality of secondary images of the same object at different in-focus positions by driving a photographing lens. The distance information detector detects distance information of the object for each of the areas of an image based on the contrast in each of the areas in each of the secondary images. The primary image capturing processor captures the same image of the object as a primary image. The image processor carries out image processing on the primary image based on the distance information.Type: GrantFiled: June 13, 2012Date of Patent: November 11, 2014Assignee: Pentax Ricoh Imaging Company, Ltd.Inventor: Hiroyasu Uehara

Patent number: 8830381Abstract: An imaging device is provided that includes an image blur evaluator, an imaging processor, a distance map generator and a filter. The image blur evaluator evaluates the amount of blurring due to a camera shake. The imaging processor captures a plurality of secondary images of the same object at different lens positions by driving a photographing lens. The distance map generator prepares a distance map including distance information of the objects captured in each area of an image based on the contrast in each of the areas. The filter reduces noise in the distance map. A relatively large filter size is selected for the filter when blurring is evaluated to be relatively large and a relatively small filter size is selected for the filter when the evaluated blurring is relatively small.Type: GrantFiled: August 10, 2012Date of Patent: September 9, 2014Assignee: Pentax Ricoh Imaging Company, Ltd.Inventor: Hiroyasu Uehara

Patent number: 8731327Abstract: An image processing system performs a position-matching operation on first and second images, which are obtained by photographing the same object a plurality of times. A plurality of shift points are detected in the second image. The shift points correspond to fixed points, which are dispersed throughout the whole of the first image. The second image is divided into a plurality of partial images, the vertices of which are positioned at the same coordinates as the fixed points in the first image. Each of the partial images are shifted to the shift points to transform the partial images so that corresponding transformed partial images are produced. The transformed partial images are combined to form a combined image.Type: GrantFiled: August 25, 2011Date of Patent: May 20, 2014Assignee: Pentax Ricoh Imaging Company, Ltd.Inventor: Hiroyasu Uehara
