Abstract: Input pixels are input to a thinning processing circuit. When thinning is performed at the thinning processing circuit, minimum values are selected in order to reduce the pixel data, whereby loss of thin lines is prevented. The thinned image data are input to a binarization processing circuit. Although the image having been thinned through selection of minimum values becomes dark as a whole, collapse of characters can be suppressed, because the binarization processing circuit dynamically changes a binarization threshold by employing, as the binarization threshold, the average of maximum and minimum values in each local region. In a density flat portion, the local maximum value and the local minimum value assume the same value. Therefore, when the difference between the local maximum value and the local minimum value is not greater than a predetermined range, binarization is performed by use of a fixed threshold value.

Abstract: An apparatus performs a process for treating development waste liquor containing photosensitive resin and surface active agent. The process subjects the waste liquor to treatment for diminishing the efficacy of the surface active agent to result in separation of the resin from the waste liquor. The waste liquor is then irradiated with ultraviolet light at 300-400 nm. The apparatus contains a tank, a stirrer, an ultraviolet source and a filter.

The file server includes directories which are created in advance in one-to-one correspondence to users and in which image data read by the image scanner is stored, and a memory in which the relationships of correspondence between identification information on users and the directories associated with the users are stored. When image data is input from the image scanner, the file server stores the image data in a directory associated with identification information input from the image scanner. Due to this configuration, an image scanner usable when connected directly to a client/server type network such as a LAN can be provided.
