Patent ID: 6906833

Claim:
An image reading device which, while a film is conveyed, reads frame images recorded on the film, comprising: a prescanning portion which reads the frame images; and a fine-scanning portion which reads the frame images more accurately than said prescanning portion; wherein said prescanning portion is provided at an upstream side, with respect to a film conveyance direction, of said fine-scanning portion, and reading of the frame images at said prescanning portion and reading of the frame images at said fine-scanning portion are carried out, while the film conveyance direction is not changed between the prescanning portion and the fine-scanning portion and a conveyance speed of the film is constant between the prescanning portion and the fine-scanning portion, such that the conveyance speed of the film for reading of a frame image at said prescanning portion is the same as the conveyance speed of the film for reading of the frame image at said fine-scanning portion.
