Image processing device to generate an interpolated image that includes a large amount of high-frequency component and has high resolution, imaging device, image processing method, and information storage device

摘要

An image processing device includes: an image acquisition section that acquires captured image data captured using an image sensor including color filters corresponding to bands, and corresponding to a plurality of frames; an alignment processing section that performs an alignment process on the captured image data to generate integrated captured image data; a reference band selection section that selects a reference band from the bands using an output image in a preceding frame; a reference image generation section that performs an interpolation process on image data included in the integrated captured image data and corresponding to the color filter corresponding to the reference band; and an interpolated image generation section that performs an interpolation process on image data included in the integrated captured image data and corresponding to the color filter corresponding to a band differing from the reference band based on a reference image to generate an interpolated image.

1. An image processing device comprising:
an image acquisition section that acquires captured image data that has been captured using an image sensor and corresponds to a plurality of frames that differ in capture time, the image sensor including a color filter array in which a plurality of color filters that respectively correspond to a plurality of bands are placed in an array; an alignment processing section that performs an alignment process on the acquired captured image data that corresponds to the plurality of frames to generate integrated captured image data; a reference band selection section that selects a reference band for generating a reference image from the plurality of bands using an output image in a preceding frame that precedes a reference frame in which the output image is generated; a reference image generation section that performs an interpolation process on image data that is included in the integrated captured image data and corresponds to a color filter among the plurality of color filters that corresponds to the reference band to generate the reference image; and an interpolated image generation section that performs an interpolation process on image data that is included in the integrated captured image data and corresponds to a color filter among the plurality of color filters that corresponds to a band among the plurality of bands that differs from the reference band based on the reference image to generate an interpolated image.
