摘要:
The memory capacity for photo film can be expanded with an external memory medium. In addition, lab service can be changed and/or added. A memory card 120 is arranged in the film player, and a small amount of information indicating the memory area of the memory card 120 which corresponds to each frame is recorded magnetically in a record track which corresponds to each frame of the photo film. A large amount of information related to each frame is recorded in the memory card 120. With this arrangement, the memory capacity for the photo film can be expanded. In addition, the memory card 120, in which the lab service program is recorded, can be used, and the lab service program can be loaded from the memory card 120 to the EEPROM 123 through the interface 124 by the film player. Therefore, although the service to the lab may be changed and/or added, a new lab service program can be entered and can give the order application to the lab with the new lab service.
摘要:
The present invention relates to a film image input method, wherein a line sensor is used as an image sensor to reduce the cost, and the image data can be corrected in accordance with the taking environment, which occurs in a case of using the line sensor, for every frame. A line sensor is provided in which photoelectric transfer elements are arranged in a direction perpendicular to a feeding direction of a long roll of developed film for a still camera, the film is fed at the first speed continuously to take the rough image data of all frames through the line sensor, and the taking environment for every frame is detected based on the taken rough image data. Thereafter, when reproducing one frame, the film is fed at the second speed which is lower than the first speed, whereby the fine image data of the desired frame are adjusted in accordance with the detected taking environment of the frame and stored in the CCD buffer, and then the image signals are output to the TV monitor based on the stored fine image data.
