Abstract:
PROBLEM TO BE SOLVED: To suppress useless power consumption during imaging by determining an optimal cooling temperature, exposure time and the like in accordance with the quantity of emitted light of a subject.SOLUTION: An image processing apparatus 100 stores beforehand table data indicating correspondence relationships between signal values based on luminescence of detection targets, cooling temperatures of a cooling means for cooling an imaging element, exposure times in imaging a subject, and S/Ns as ratios between the signal values based on the luminescence of the detection targets and luminescence of background portions of the detection targets. The detection target is pre-imaged with a predetermined reference cooling temperature and a predetermined reference exposure time and an S/N at that time is calculated. From among combinations of cooling temperatures and exposure times corresponding to the signal value based on the luminescence of the detection target during pre-imaging, a combination of a cooling temperature and an exposure time with which the S/N becomes equal to or greater than the reference S/N is determined on the basis of a result of comparison between the calculated S/N and a predetermined reference S/N as a cooling temperature and an exposure time for main imaging from the table data, and main imaging is performed under the determined conditions.
