Electronic camera video signal correcting device

A video signal correcting device of an electronic camera comprising:

• a storage unit which stores therein a white spot address, a white spot level, and a reference dark current level median obtained from a video signal at a time of dark shooting, and a temperature, a sensitivity, and a time-in-second at the time of dark shooting, as well as a temperature coefficient for correcting the white spot level and a dark current level median in accordance with a temperature at a time of shooting by the electronic camera, a sensitivity coefficient for correcting the white spot level and the dark current level median in accordance with the sensitivity of the electronic camera, and a time-in-second coefficient for correcting the white spot level and the dark current level median in accordance with an exposure time-in-second of the electronic camera;
• a temperature detection unit which detects the temperature at the time of shooting;
• and
• an operation unit which obtains a correction value for the white spot level due to a temperature and a correction value for the dark current level median due to a temperature according to a difference between a temperature at a time of shooting a subject detected by said temperature detection unit and the temperature at the time of dark shooting stored in said storage unit and to the temperature coefficient stored in said storage unit, obtains a correction value for the white spot level due to a sensitivity and a correction value for the dark current level median due to a sensitivity according to a difference between a sensitivity at the time of shooting a subject and the sensitivity at the time of dark shooting stored in said storage unit and to the sensitivity coefficient stored in said storage unit, obtains a correction value for the white spot level due to time-in-second and a correction value for the dark current level median due to a time-in-second according to a difference between a time-in-second at the time of shooting a subject and the time-in-second at the time of dark shooting stored in said storage unit and to the time-in-second coefficient stored in said storage unit, and performs correction on the white spot level and the dark current level median both included in the video signal at said time of shooting a subject according to each correction value for the white spot level due to the temperature, the sensitivity, and the time-in-second.
