The insertion filter amount of each filter of the dimming filter 24 is corrected by the drive control device 21 based on the exposure correction amount of each frame described above, and each filter is corrected by the filter driving unit 26. Only the amount is inserted into the optical path.

The light that has passed through the light control filter 24 passes through one frame image of the negative film N positioned at the printing position around the optical axis L1 by the negative transport unit 28, and then passes through the projection lens 30. Exposure stage S1 for the color paper P positioned by the paper transport unit 32.
Is irradiated for a predetermined time. In this way, each frame image recorded on the negative film N in the main printing section 20 is printed and exposed on the color paper P.

Further, the liquid crystal panel 48 has a large number of pixels (about 510,000 pixels, for example) capable of displaying white, black, and intermediate colors thereof regularly arranged on the display surface by electrical means. The liquid crystal panel driver 50 receives the image information of several items temporarily stored in the non-volatile storage device 51 via the drive control device 49, and forms index image data in which frame images are arranged according to a predetermined rule for each item. Then, it is possible to form on the liquid crystal panel 48 images corresponding to image data of a predetermined number of frames of the formed index image data, for example, 10 frames (two columns). Further, it is also possible to form on the liquid crystal panel 48 an image corresponding to the image data of only the R, G, and B color components of the image data for the two columns.

Since the non-volatile storage device 51 is non-volatile, even if the power of the photo printer 10 is turned off due to an accident such as a power failure, the stored exposure correction amount information and image data of each frame are retained. Also,
The drive control device 21 also stores the transmitted information on the exposure correction amount of each frame in a predetermined storage device (not shown).

In the main printing section 20, the negative film N
