摘要： An observation imaging apparatus includes an insertion unit, an imaging lens, and an image sensor. The imaging lens is disposed in such a manner that an axial principal ray of an observation subject side surface of a lens is tilted with respect to a normal line passing through the center of gravity of a section of the insertion unit, the section passing through the center of an effective imaging range of the image sensor and having the smallest area. A point on the axial principal ray at which the distance between the normal line and the axial principal ray is smallest is located on the image side relative to the observation subject side surface of the lens and on the observation subject side relative to the image sensor. The observation imaging apparatus satisfies a predetermined conditional expression.

摘要： To provide an image-capturing system capable of maintaining high analysis accuracy while reducing the amount of data related to image acquisition with a simple method. In order to achieve the object, the image-capturing system includes an image-capturing device configured to acquire image data of a subject, and an image-capturing control device configured to control image acquisition by the image-capturing device. The image-capturing control device includes a difference extraction means configured to extract difference data on the basis of any two image data items acquired by the image-capturing device, a change amount extraction means configured to extract change amount data on the basis of any two difference data items extracted by the difference extraction means, and a condition change means configured to change an image acquisition condition in the image-capturing device on the basis of the change amount data extracted by the change amount extraction means.
