CPUgenerates memory card loading/unloading information, based on memory card loading/unloading detection signals inputted from memory I/O. Memory I/Oworks even when the power supply is in the OFF condition. CPUalso generates memory card control information of loaded memory cards Aand B, and stores it in RAM When the power supply is re-activated, CPUrecognizes that memory card control information was stored in RAMunder the power OFF condition, generates memory card control information of loaded memory cards Aand B, and compares that with memory card control information which was stored in RAMwhen the power was turned off, and then judges whether loaded memory cards Aand Bare the same as the cards which were used when the power was turned off.

The photographic film scanner further includes a scanner for reading image information from one of the rolled film, accommodated in the cartridge, and the film, held by the second film carrier; a detector for detecting a load of the first film carrier and the second film carrier into the carrier receiver; a contact point for electrically connecting the carrier receiver section and the first film carrier; and a discrimination circuit for automatically discriminating between the first film carrier and the second film carrier by sending electric signals through the contact point when the detector detects the load of one of the first film carrier and the second film carrier.

Photographic image processing apparatus

Provision is made of a carrier for holding a piece film cut every after several frames and a carrier for holding a long wound film contained in a cartridge and having a motor for frame-feeding. When the carrier is loaded, the carrier is driven at a high speed by a first stepping motor and is driven to a predetermined position, to optically detect whether the carrier is for holding the piece film or for holding the long wound film. When the carrier is for holding the piece film, the carrier is driven at a high speed by the first stepping motor and is prescanned. When the carrier is for holding the long wound film, the carrier is driven by a second stepping motor and is prescanned. In the main scanning, both of the carriers are driven by the second stepping motor at a low speed, so that image is read maintaining a high resolution.

Film scanner

In a state where no original document is set, light emitted from a light source 6 is received by a sensor 5, a integrated light quantity reference value with which an output is made to be predetermined value V0 is obtained (P1), a magnification of the quantity of light and a gamma correction table are produced from gamma function data for prescanning (P2-1), a quantity of light for prescanning is obtained in accordance with a light quantity adjustment value obtainable from the magnification of the quantity of light and the integrated light quantity reference value and prescanning of a color negative film is performed (P2-2), and an image signal obtained by prescanning is converted with the gamma correction table so as to output image data (P2-3). A magnification of the quantity of light is determined and the gamma correction table is produced from gamma function data for main scanning produced in accordance with image data obtained in prescanning (P3-1), a quantity of light for main scanning is obtained from the magnification of the quantity of light and the integrated light quantity reference value to perform main scanning (P3-2), and the gradient of an image signal obtained from this is further converted with the gamma correction table so as to output mainly-scanned image data (P3-3).
