Abstract: PROBLEM TO BE SOLVED: To enhance operability of film photographing operation by enabling immediate display of an image of negative film on an LCD monitor by converting the image into a positive image at high speed. SOLUTION: A negative/positive conversion parameter for display is judged whether it is calculated or not when photographed film 200 is a negative film, i.e., an image of film obtained by an imaging element 112 and a image pickup circuit 113 is the negative image by a system controller 114. When the negative/ positive conversion parameter for display is not calculated, i.e., for the negative image of a first frame after a power is supplied, the negative/positive conversion parameter for display is calculated from the negative image and displayed on an LCD after negative/positive conversion of it.  On the other hand, for negative images of a second frame and afterward, the negative/positive conversion is performed by the same negative/positive conversion parameter as the negative image of the first frame and the images are displayed on the LCD without calculating the negative/positive conversion parameter for display.
