Title: (EN) IMAGE PROCESSING APPARATUS, OPTICAL COHERENCE TOMOGRAPHY APPARATUS, IMAGE PROCESSING METHOD, AND COMPUTER-READABLE STORAGE MEDIUM
Abstract: front page image
(EN)

An image processing apparatus that processes a tomographic image generated by using tomographic signals acquired by subjecting a subject to optical coherence tomographic imaging, includes an acquiring unit configured to acquire the tomographic signals, and a generation unit configured to generate a tomographic image based on a representative value in each pixel position of the tomographic image, generated by using the tomographic signals, the generation unit includes a region determination unit configured to determine a target region where contrast is reduced in the tomographic image, by using tomographic signals, and an estimation unit configured to estimate an estimation value, by performing statistical processing on tomographic signals corresponding to a pixel position of the tomographic image out of the tomographic signals, and the generation unit generates the tomographic image with the estimation value as the representative value in the target region.
