To provide a satisfactory focused image when projecting the image of a prescribed object again.

Concerning the configuration of this camera, the surrounding temperature of lenses 1a and 1e is detected by a temperature sensor 1d, the moving position of the lenses 1a and 1e at the time of picking up the image of the prescribed object at a prescribed image angle is stored as a preset point in a storage means 9, the temperature at the time of preset point storage is stored and when projecting the image of the said prescribed object again, based on the temperature at the time of preset point storage and a temperature at a current time point, the position deviation of the preset point in the direction of optical axis caused by a temperature change is corrected by a correcting means 7b.
