  • Publication number: 20010024528
    Abstract: An image compression apparatus and method, and a carrier wave encoded with a computer readable control program having instructions for use by a computer, perform an image compression process. A compression level is determined for use in compressing a picture image to a predetermined target data amount by iteratively compressing a reduced version of the picture image in order to determine the compression level that is to be used to compress the picture image. First, a reduced-size picture image is created from the picture image that is to be compressed. A preliminary compression target data amount is then derived, for example, based on the target data amount, the data amount of the picture image and the data amount of the reduced-size picture image. The reduced-size picture image is then compressed using a compression level. The size of the resulting compressed reduced-size picture image is compared to the preliminary compression target data amount.

  • Patent number: 6252625
    Abstract: A film image reading apparatus and method which more quickly reads images from a cartridge of developed film for production of thumbnail images which are displayed on a monitor. The apparatus reads a first image from the film cartridge using imaging condition values associated with each frame image. These imaging condition values include photographic information such as, exposure value, white balance value and focus adjustment. In the event that the first or current image being read by the apparatus is the start of a series of photographic images, the film image reading apparatus will set the exposure value, the white balance value and the focus adjustment only once for the entire series. The remaining images of the series are then read using the imaging condition values of the first image of the series. In this manner, these imaging condition values are not reset for each image and time is saved in reading the series of images from the film.
