| 20160094782 | AUTO-FOCUS IMAGE SYSTEM - Exclusion filters are created to remove edges that are unlikely to belong to the object of interest before focus signal is generated from the remaining edges detected in image. Exclusion ranges defined in one or more edge characteristics are created from bins of distributions of edges with respect to the respective characteristics that have low numbers of sharp-enough edges. The exclusion filters subsequently remove edges that fall into the exclusion ranges. An edge characteristic is chosen over another if the percentage of sharp-enough edges in the output of its exclusion filter is higher. An edge characteristic is eliminated from exclusion filtering if a new exclusion filter in the same edge characteristc but calibrated from another image results in the percentage being significantly different. | 03-31-2016 |
| 20160112627 | IMAGE PROCESSING DEVICE, METHOD OF PROCESSING IMAGE, IMAGE PROCESSING PROGRAM, AND IMAGING DEVICE - An information processing system configured to perform predetermined processing based on out-of-focus information corresponding to a first area of an image, the out-of-focus information corresponding to a difference in focus between the first area of the image and a second area of the image that is different from the first area of the image. | 04-21-2016 |
| 20160140698 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, PROGRAM, PRINTING MEDIUM, AND RECORDING MEDIUM - When obtaining subband signals by performing multiresolution decomposition on image data using a broad-sense pinwheel framelet or a pinwheel wavelet frame, having a degree, that is a set of an approximate filter with no orientation and a plurality of detail filters with respective orientations, and acquiring processed image data by the subband signals in a decomposition phase of the multiresolution decomposition, or processed image data that has been reconstructed into an image by summing the subband signals in a synthesis phase of the multiresolution decomposition, the present invention performs attenuation or amplification of the subband signals in the decomposition phase of the multiresolution decomposition that correspond to at least one of the filters. | 05-19-2016 |
| 20160165126 | IMAGE PROCESSING DEVICE, IMAGING DEVICE, IMAGE PROCESSING METHOD, AND COMPUTER PROGRAM PRODUCT - According to an embodiment, an image processing device includes a processing circuit configured to implement a first acquirer, a second acquirer, a first calculator, and a second calculator. The first acquirer acquires an all-in-focus image. The second acquirer acquires a first captured image taken at a first focus distance. The first calculator calculates, with respect to a pixel included in the first captured image, a first blur circle radius using the all-in-focus image and the first captured image. The second calculator calculates a first depth representing a distance to an object included in at least one of the first captured image and the all-in-focus image using the first blur circle radius. | 06-09-2016 |

| 20220138909 | NOISE PROCESSING IN IMAGE FRAMES FOR DIGITAL VIDEO - Aspects relate to noise processing of image frames for video. An example device is configured to perform operations including receiving a sequence of image frames for a digital video, determining an image quality metric of a first image frame from the sequence of image frames, and determining a number of image frames from the sequence of image frames to be blended based on the image quality metric (with the number of image frames including the first image frame). The operations also include blending the number of image frames to generate a blended image frame of the digital video. The image quality metric may include a light intensity metric (such as a luminance metric measured during an autoexposure operation) or a sharpness metric (such as a focus metric measured during an autofocus operation). | 05-05-2022 |
