Abstract
An imaging unit of the disclosure includes: a camera; a holding member configured to hold an imaging target object to be imaged by the camera; a light irradiation device configured to irradiate lights of different wavelengths from multiple light sources towards the imaging target object held by the holding member; and a control device configured to obtain a proper resolving power value for a light or lights of one or more light sources selected from the multiple light sources for use for imaging, irradiate the light or lights of the one or more light sources so selected onto the imaging target object to image the imaging target object using the camera, and make use of the proper resolving power value in processing an image obtained from the camera.
Claims7
An imaging unit comprising:
- a camera;
- a holding member configured to hold an imaging target object to be imaged by the camera;
- a light irradiation device configured to irradiate lights of different wavelengths from multiple light sources towards the imaging target object held by the holding member;
- and
- a control device configured to obtain a proper resolving power value for a light or lights of one or more light sources selected from the multiple light sources for use for imaging, irradiate the light or lights of the one or more light sources so selected onto the imaging target object to image the imaging target object by the camera, and make use of the proper resolving power value in processing an image obtained from the camera.
An imaging unit comprising:
- a camera;
- a holding member configured to hold an imaging target object;
- a distance adjusting device configured to adjust a distance between the camera and the holding member;
- a light irradiation device configured to irradiate lights of different wavelengths from multiple light sources towards the imaging target object held by the holding member;
- and
- a control device configured to obtain a proper value for the distance for a light or lights of one or more light sources selected from the multiple light sources for use for imaging based on an image forming point on an optical axis which changes according to a longitudinal chromatic aberration and control the distance adjusting device so that the actual distance becomes the proper value for the distance.
