APPARATUS AND CONTROL METHOD THEREFOR

摘要

An imaging apparatus controls a size of an imaging region according to a spread of Z positions of substances in an object. For example, the imaging region becomes wide when the spread is small and becomes narrow when the spread is large. Or, the number of image sensors to be used is increased when the spread is small and is decreased when the spread is large. Or, an image sensor having a wide image pickup area is used when the spread is small, and an image sensor having a narrow image pickup area is used when the spread is large.

主权项

1. An imaging apparatus that images an object and generates a digital image, comprising:
an image sensor; an imaging optical system that enlarges and forms an image of the object on the image sensor; and an imaging control unit for controlling a size of an imaging region which is a range in which image data are acquired by the image sensor in one imaging cycle and controlling a focal position when the imaging region is imaged, wherein the object includes substances with different Z positions, which are positions in the optical axis direction of the imaging optical system; and the imaging control unit determines the size of the imaging region according to a spread of the Z positions of the substances so that the imaging region in the case where the spread of the Z positions of the substances is relatively large is narrower than the imaging region in the case where the spread of the Z positions of the substances is relatively small.
