FOCUS DETERMINATION APPARATUS, FOCUS DETERMINATION METHOD, AND IMAGING APPARATUS

摘要

A write region is detected based on an image of an object, when performing split imaging of the object using a microscope. When a certain region includes a feature region that is a region in which an image feature related to a color or an image feature related to smoothness of a change in a pixel value satisfies a predetermined condition, and when the feature region has an area equal to or greater than a predetermined value in the image, the region is determined to be a write region. For an imaging position within the write region, an in-focus position of the imaging position is determined based on a value of an in-focus position of a position different from the imaging position.

1. A focus determination method for determining an in-focus position in an optical axis direction at each of imaging positions when performing split imaging of an object using a microscope, the focus determination method comprising:
a write region detection step of detecting a write region in which writing is performed on the object, based on an image obtained by imaging the object; and an in-focus position determination step of determining an in-focus position of each of the imaging positions, wherein when a certain region includes a feature region that is a region in which an image feature related to a color or an image feature related to smoothness of a change in a pixel value satisfies a predetermined condition, and when the feature region has an area equal to or greater than a predetermined value in the image, the region is determined to be a write region in the write region detection step, and for an imaging position within the write region, an in-focus position of the imaging position is determined based on a value of an in-focus position of a position different from the imaging position, in the in-focus position determination step.
