Abstract
A low cost image reading apparatus and an image reading method is obtained which allows a high speed image reading process to be performed. When a frame image recorded on a negative film is read, the amount of light of a lamp and the charge accumulation time of a CCD area sensor provided in the prescan section of a film image reading apparatus are fixed. An image buffer is also provided for holding the density values data (the image data) obtained by the fine scan section until the auto setup processing and positive image examination, which are based on the density values data, are completed.
