Abstract: An image pickup system includes a thermography camera configured to pick up an image of an infrared light band, and a processor. The processor detects, from a difference in a temperature distribution between a thermography image for a subject obtained by image pickup of the subject using the thermography camera and a reference thermography image obtained by image pickup of the subject using the thermography camera, a change amount in the temperature distribution of the subject, detects a changed area of the subject where the detected change amount is a predetermined value or more, and generates a display image for displaying information about the detected changed area on a monitor.

Abstract: An endoscope apparatus is an endoscope apparatus having an insertion portion having an image pickup device in a distal end portion, and a main body portion, and has a drive circuit that outputs a drive signal that drives the image pickup device, and a changing section that changes at least one of a pulse width and a peak value of a reset gate signal included in the drive signal, in response to a temperature of a vicinity of the image pickup device or the main body portion.
