ABSTRACT:
The present invention is a panoramic photograph processing system which will provide a non-peculiar panoramic photograph with continuous color and brightness between consecutive photographs by setting the same exposure condition for panorama-mode frames of a film and performing printing of the panorama-mode frames under the same exposure condition. An output from a photometric sensor is amplified by an amplifier and is then converted to a digital signal by an A/D converter. The digital signal is supplied to a central processing unit (CPU). The digital photometric data from the A/D converter is input to the CPU together with various pieces of photograph information from a photograph information input circuit. A liquid crystal for displaying a shutter speed and a panorama-mode in a finder and a liquid crystal for displaying a latent image bar code data indicating the start position of a panorama-mode are controlled by the CPU via liquid crystal drivers. A bar code pattern formed by the latter liquid crystal via the associated liquid crystal driver is irradiated by a light source to be recorded as latent image data on the film.
