Abstract:
1. An image display apparatus that displays an image based on in-vivo image data obtained from a capsule endoscope that captures an in-vivo image of a subject via a receiving apparatus that performs wireless communication with the capsule endoscope, the apparatus comprising: a storage unit configured to store the in-vivo image data and information that is associated with the in-vivo image data and related to a position of the capsule endoscope in the subject; an image processing unit configured to perform image processing on the in-vivo image data stored in the storage unit; a position estimating unit configured to estimate a position of the capsule endoscope in the subject upon capturing the in-vivo image, based on the information related to the position and performs first position estimation processing at a predetermined sampling density for all the position information associated with the in-vivo image data, and, after the first position estimation processing is completed, performs second position estimation processing for all the position information at a higher sampling density than the first position estimation processing; a display unit configured to display the in-vivo image based on the in-vivo image data on which the image processing is performed in the image processing unit and to display the position of the capsule endoscope estimated by the position estimating unit; a display control unit configured to control the display unit to display the in-vivo image and to display the position of the capsule endoscope; and a control unit configured to perform image processing in the image processing unit and position estimation processing in the position estimating unit in parallel, wherein when the image processing by the image processing unit is completed and the position estimation processing by the position estimating unit is not completed, the control unit is configured to control the display control unit to display, on the display unit, the in-vivo image based on the in-vivo image data, and information indicating that the position estimation processing is currently performed, and is configured to cause the position estimating unit to perform the position estimation processing concurrently with displaying the in-vivo image; the display control unit causes the display unit to display the position of the capsule endoscope based on a result obtained by the first position estimation processing, when the first position estimation processing is completed; and the display control unit causes the display unit to display a processing status of image processing in the image processing unit and a processing status of position estimation processing in the position estimating unit.
