| 摘要 | An image processing apparatus 1 includes an image region dividing portion 105 configured to divide a shot image into a plurality of image regions so that an amount of change of an image quality is within a predetermined range when the shot image is blurred using a blur kernel depending on an object distance and an angle of view of the shot image, a blur kernel generating portion 106 configured to calculate the blur kernel for each image region divided by the image region dividing portion 105, and an image processing calculating portion 107 configured to generate a blur-added image by performing a convolution calculation for the shot image using the blur kernel calculated by the blur kernel generating portion 106. | ||

| 主权项 | 1. An image processing apparatus comprising: an image region dividing portion configured to divide a shot image into a plurality of image regions so that an amount of change of an image quality in each of the plurality of image regions is within a predetermined range when the shot image is blurred using a blur kernel depending on an object distance and an angle of view of the shot image; a blur kernel generating portion configured to generate a plurality of blur kernels for the respective image regions divided by the image region dividing portion; and an image processing calculating portion configured to generate a blur-added image by performing a convolution calculation for the shot image using the blur kernels generated by the blur kernel generating portion. | ||
