摘要 PROBLEM TO BE SOLVED: To provide a camera and optical instrument by which an amply atmospheric photograph that reflects a photographer's intent can be finely taken by estimating and displaying a difference between images taken by changing a shutter speed. SOLUTION: In photographing, an image signal from a photographic subject 30 is exposed for a given period of time to obtain the imaging signal with an imaging device 14. A switching of the given period of time in the exposure is performed by a changeover switch. Then, before the photographing, an output signal from the imaging device 14 is iteratively input at given intervals with an exposure time shorter than the above given period of time to detect a temporal change, in the output of the imaging device 14 by an image decision unit 18. Further, according to the detected results of the change, an image taken in photographing the photographic subject is estimated by an image processor 20 and an effect estimation unit 17a to be displayed on a display unit 21.
