Abstract
A color negative inspection apparatus which reads color image data from a frame of a color negative film and stores in a memory color image data sequentially read from N frames of the color negative film, N being an integer at least as large as 2. The N color positive images are displayed based on the color image data stored in the memory. The N color positive images correspond to the N frames of the color negative film. The N color positive images are shifted by one frame each time color image data is read from a frame of the color negative film.
