IMAGE PROCESSING APPARATUS, IMAGE PICKUP APPARATUS, IMAGE PROCESSING METHOD, AND PROGRAM

摘要

There is provided an image processing apparatus including an HDR (High Dynamic Range) processing unit inputting images picked up while exposure control that changes an exposure time is being carried out with a predetermined spatial period and a predetermined temporal period on pixels that compose an image sensor, and carrying out image processing. The HDR processing unit generates a first combined image by combining pixel values of a plurality of images with different sensitivities generated by an interpolation process using a plurality of consecutively picked-up images, generates a second combined image by combining pixel values of a plurality of images with different sensitivities generated by an interpolation process that uses a single picked-up image, and generates an HDR image by executing a pixel value blending process on the first combined image and the second combined image in accordance with a blending ratio calculated in accordance with movement detection information.

1. An image processing apparatus comprising:
an HDR (High Dynamic Range) processing unit inputting images that have been picked up while exposure control that changes an exposure time is being carried out with a predetermined spatial period and a predetermined temporal period on pixels that compose an image sensor, and carrying out image processing, wherein the HDR processing unit: generates a first combined image by combining pixel values of a plurality of images with different sensitivities generated by an interpolation process using a plurality of images that have been picked up consecutively; generates a second combined image by combining pixel values of a plurality of images with different sensitivities generated by an interpolation process that uses a single picked-up image; and generates an HDR (high dynamic range) image by executing a pixel value blending process on the first combined image and the second combined image in accordance with a blending ratio calculated in accordance with movement detection information.
