摘要:
A scanner 1 reads image information at read resolution set by a resolution control section 3 and stores the image information in memory 2. An image separation section 11 separates the image information into a first image plane (picture part), a second image plane (text part color information), and a selection image plane (text part forms) for selecting either the first or second image plane. The resolution control section 3 sets optimum resolutions in first to third resolution conversion sections 12-14 in response to image quality, the original type, the system environment, the image plane characteristics, etc. The three image planes are converted into the resolutions set in the first to third resolution conversion sections 12-14. The image planes after undergoing the resolution conversion are compressed in first to third compression sections 15-17 and wrapped in one data format by an image format section 18.
摘要:
Input image information undergoes color conversion processing in a color conversion section 1, then is separated into first piece of image data, second piece of image data, and selection data in a multilayer data processing section 2 and transmission data in the multilayer data format is output. On the other hand, a 1-layer data processing section 3 prepares transmission data in the normal 1-layer data format from the image information. A color determination section 4 determines whether the input image information is a color or monochrome image. If the image information is determined a color image, a selection section 6 selects the transmission data in the multilayer data format; if the image information is determined a monochrome image, the selection section 6 selects the transmission data in the 1-layer data format. Then, it transmits the selected transmission data through a transmission section 7.
