Image processing apparatus, image processing method and storage medium for acquiring an omnifocal image by combining multiple images with a specific order

摘要

An imaging apparatus includes a captured image acquisition unit, a combination sequence determination unit, and an image combination unit. The captured image acquisition unit acquires data of multiple captured images that have been imaged at multiple focus positions. The combination sequence determination unit determines a sequence of the images imaged by an imaging unit, the sequence being different from both a progressive sequence of focus distances and a sequence of imaging, to be a sequence for combining the data of the multiple captured images acquired by the captured image acquisition unit. The image combination unit combines the multiple captured images imaged by the imaging unit, in the order determined by the combination sequence determination unit, creating data of an omnifocal image.

主权项

1. An image processing apparatus comprising a CPU, wherein the CPU is operable as:
an image acquisition unit that acquires data of a plurality of captured images that are imaged at a plurality of focus positions; a sequence determination unit that determines a sequence of combination for combining data of a plurality of the captured images, the sequence of combination being different from both (i) a progressive sequence of focus distances and (ii) a sequence of imaging; a reference image specification unit that specifies a reference image to be a reference for combining; and a combination unit that, based on the reference image specified by the reference image specification unit, combines the data of the plurality of the captured images in the sequence of combination determined by the sequence determination unit, and creates data of an omnifocal image, wherein the sequence determination unit alters the sequence of combination based on relationships between focus positions of the captured images acquired by the image acquisition unit and a focus position of the reference image.
