Abstract
In a color facsimile apparatus, a color image file, or the like, an encoding system suitable for a color image to be transmitted is promptly selected and the image data is transmitted. The apparatus has: the color image input unit 20 to read a color image; a plurality of color image encode units 22 and 24 including the white/black image encoding; the storage units 23 and 25 to store the encode data; the means 28 and 29 for decoding the encode data; the means 32 for displaying the decoded image; and the protocol means 27 with an apparatus on the partner side.
Claims24
An image encoding apparatus comprising:
- input means for inputting image data representing an original;
- first encoding means for encoding the image data as binary image data representing the original;
- second encoding means for encoding the image data as multilevel image data representing the original;
- selecting means for selecting one of the image data encoded by said first or second encoding means;
- and
- transmitting means for transmitting the image data selected by said selecting means,
- wherein said first encoding means encodes the image data as binary image data line by line and said second encoding means encodes the image data as multilevel image data block by block, each block being a two-dimensional block having a plurality of pixels, and
- wherein said first encoding means and said second encoding means encode the same image data of one original in parallel.
