摘要： An image processing method, includes: an input step in which a computer acquires data of a plurality of input images acquired by imaging performed using a same image sensor; and an optimization process step in which a computer determines an optimal solution of brightness change with respect to each input image by performing iterative calculations using an iterative method to improve overall image quality of the plurality of input images. In the optimization process step, an optimal solution of brightness change for each pixel of each input image is determined under a condition that common brightness change is performed with respect to pixels at a same position in respective input images.

摘要： An image generating apparatus includes: an input unit that inputs data on a defocused image group; a storage unit that stores data on a plurality of filters generated based on a three-dimensional blur function; and a computing unit that generates a new image by applying the filter to the defocused image group. When a first element of a first filter out of the plurality of filters is symmetrical or anti-symmetrical with a second element included in the first filter or a second filter, which is different from the first filter, the storage unit does not store the data on the first element, and the computing unit generates the data on the first element of the first filter based on data on the second element which is stored in the storage unit when the first filter is used.

摘要： An image processing method includes the steps of: generating, based on data of a plurality of images acquired by performing imaging using a same image sensor, a weight coefficient corresponding to each image so that a weight coefficient corresponding to an image of which a brightness change is smooth is relatively large; integrating the data of the plurality of images using the weight coefficients to generate data of an integrated image; applying smoothing to the data of the integrated image to generate data of a smoothed integrated image; and generating, based on the data of the integrated image and the data of the smoothed integrated image, data of estimated fixed-pattern noise which is an estimated value of fixed-pattern noise attributable to the image sensor.
