Abstract: A camera that is able to capture images of moving subjects as video images, that has a large depth of field and is thus able to capture images of thick objects, and that is able to capture images of living cells and tissues as well as tissues in water. One example includes an image pickup element and an objective lens disposed between the image pickup element and a subject. A photosensitive surface of the image pickup element has elements sensitive to light in the red, green, and blue spectral regions. Using chromatic aberration of the objective lens to form an image, the respective elements sensitive to light from the red, green and blue spectral region, collect light from respective surface segments XR, XG, and XB that lie at different heights in the subject. The images taken by the respective elements are imaged individually and produced on a monitor.
