Abstract
Abstract In a film image input method, a line sensor is used as an image sensor to reduce the cost. 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. 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. Then, the image signals are output to the TV monitor based on the stored fine image data.
