3. The image display system according to claim 1, wherein the control unit outputs image data of a predetermined number of medical images arranged at positions in an order before the first medical image to the first medical image. An image display system characterized in that weighted addition is performed on an image, and the weighted and added medical images are sequentially updated and displayed.

4. The image display system according to claim 1, wherein the control means displays the updated display when the first medical image exists in an order later than the medical image that is updated and displayed. An image display system, wherein a predetermined number of medical images from a medical image to the first medical image are weighted and added, and the weighted and added medical images are sequentially updated and displayed.

In the image display system according to claim 1, 2, 3, or 4,
Means for creating a plurality of images taking into account the afterimage effect between the images at the time of update display of the plurality of medical images according to the update display direction;
An image display system comprising: display means for sequentially updating and displaying the created plurality of images in the order of their spatial positions.

6. The image display system according to claim 5, further comprising means for variably setting the afterimage effect according to a display speed of the plurality of medical images, wherein the plurality of images taking into account the afterimage effect. Image display system.

7. The image display system according to claim 5, wherein a medical image updated in a first direction in which the plurality of medical images are successively located is displayed on the display unit, or the first direction is displayed. An image display system further comprising means for selecting whether to display a medical image updated in a second direction opposite to the display direction on the display means.

6. The image display system according to claim 5, wherein the display means includes a first medical image that is updated in a first direction in which the plurality of medical images are successively located, and the first direction. An image display system characterized by alternately displaying a second medical image updated in a second direction opposite to the second direction.

9. The image display system according to claim 8, wherein means for detecting an abnormal shadow based on the medical image and the first and second medical images including the detected abnormal shadow as the specific medical image are used as the first and second medical images. Means for generating a medical image, wherein the display means alternately displays the generated first and second medical images.

The image display system according to claim 1, wherein predetermined weighting processing is performed on each of a plurality of medical images acquired by sequentially changing the spatial position with respect to a predetermined position of the subject according to the order of the spatial positions. Means for
