20150195448 | IMAGING DEVICE AND IMAGE PROCESSING METHOD - According to the present invention, even if variation (estimation variation) is caused in a subject distance estimated at the time of imaging when restoration processing of a taken image is performed using a restoration filter corresponding to the subject distance, since an optimal restoration filter that conforms to a subject distance taking into account the maximum infinity-side estimation variation and does not cause overcorrection is selected, it is possible to prevent resolution degradation due to overcorrection and achieve the improvement of resolution by the restoration filter. | 07-09-2015 |

20150207962 | IMAGE-PROCESSING DEVICE, IMAGE-CAPTURING DEVICE, IMAGE-PROCESSING METHOD, AND RECORDING MEDIUM - According to an aspect of the present invention, for which of the original image data before the gradation correction and the original image data after the gradation correction the restoration process is performed is determined depending on whether or not the image information meets the condition under which the ringing appears in the recovery image data due to the restoration process. When the gradation correction is performed after the restoration process, there is a probability that the side effect (the ringing or the like) of the restoration process is emphasized by the gradation correction. Therefore, in the case where the image information meets the condition under which the ringing appears, it is possible to prevent such a side effect (the ringing or the like) of the restoration process from being emphasized by the gradation correction, by performing the restoration process for the original image data after the gradation correction. | 07-23-2015 |
20150208051 | IMAGE-PROCESSING DEVICE, IMAGE-CAPTURING DEVICE, IMAGE-PROCESSING METHOD, AND RECORDING MEDIUM - A restoration process using a restoration filter that is based on a point spread function for an optical system is performed for original image data acquired from an image-capturing element by an image taking of an object image using the optical system, so that recovery image data are acquired. The above restoration process is performed, in a point-image restoration processing section, for color data of the original image data in which a gradation correction has been performed by a logarithmic process. The restoration filter may be configured by a filter coefficient corresponding to the image data before the logarithmic process, or may be configured by a filter coefficient corresponding to the image data after the logarithmic process. Thus, by performing the restoration process capable of flexibly responding to various properties of the original image, it is possible to reduce the image degradation such as the ringing in the recovery image. | 07-23-2015 |
20150271461 | IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND RECORDING MEDIUM - According to an aspect of the present invention, when the abnormal oblique incident light is not detected, the first color mixture correction based on the pixel data of the adjacent pixel to the correction target pixel is performed for the pixel data of the correction target pixel, and when the abnormal oblique incident light is detected, the second color mixture correction based on the pixel data of the peripheral pixel to the correction target pixel is performed. Therefore, this aspect can be applied, particularly, even to an imaging element having a large array matrix size, and it is possible to solve the level difference among same-color pixels that occurs due to the influence of the leakage of the abnormal oblique incident light (the ghost light and the like) to the adjacent pixel, and to suppress the image quality degradation due to the abnormal oblique incident light. | 09-24-2015 |
20150317776 | IMAGE PROCESSING DEVICE AND IMAGE CAPTURE DEVICE - An image processing device according to an embodiment of the present invention obtains recovery image data by performing restoration processing using a restoration filter based on a point spread function of an optical system, on original image data obtained from an imaging element by imaging using the optical system. The restoration filter used in this restoration processing (a combination filter and realization filter Fr) is generated by combining multiple base filters Fb. Base filter Fb may be arbitrarily selected from filters that are confirmed beforehand to be effective to prevent image quality degradation. | 11-05-2015 |
20150326838 | IMAGING DEVICE, IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD AND PROGRAM - Pixels constituting the imaging element include at least four types of the determination pixels for which color filter patterns of adjacent pixels thereof are different from one another. At least one of pixels, which are adjacent to each determination pixel, is a first color pixel that has a color filter with a first color. Further, among the pixels which are adjacent to each determination pixel, a pixel, which is opposed to the first color pixel with the determination pixel interposed therebetween, has a color filter other than the color filter with the first color. Abnormal oblique incident light, which is incident into the imaging element, is detected on the basis of average values of the respective pixel data pieces corresponding to the types of these determination pixels. | 11-12-2015 |
