  • Publication number: 20230171474
    Abstract: Provided are an imaging controller, an operation method and program of the imaging controller, and a camera capable of presenting a radiation image of a subject to a user in an easy-to-understand manner. An image sensor driving control unit causes an image sensor to image a visible ray to acquire a first image including a reflected image of a subject. The image sensor driving control unit causes the image sensor to image an infrared ray to acquire a second image including the reflected image and a radiation image of the subject. A zoom lens driving control unit moves a zoom lens along an optical axis to correct a difference in angle of view between the first image and the second image. Image processing units output difference images between the first image and the second image acquired in a state in which the difference in angle of view is corrected.

  • Publication number: 20230018238
    Abstract: A blur correction device includes a processor and a memory that is built into or coupled to the processor. The processor is configured to acquire an amount of blur correction used to correct blurring of an image obtained by imaging of an imaging element during exposure for one frame in the imaging element, and correct the blurring by performing image processing based on a most recently acquired amount of blur correction, on an unfinished image that is the image less than one frame that is being read from the imaging element. In a case in which a first reading period does not overlap with a second reading period, the processor corrects the blurring by performing the image processing based on the amount of blur correction acquired during exposure between the first reading period and the second reading period, on the unfinished image of the subsequent frame.
