Title: Image coder and decoder
Inventor: OSAWA HIDESHI
IPC: H04N1/411
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a memory with a large capacity for rotation processing of an image by coding only blocks with picture elements of different colors at a coder for every block and allowing a decoder to decode and rotate picture elements in the block. SOLUTION: A full white block discrimination section 102 sets a flag when in-block picture elements are all at a white level and does not use the picture elements in this block as a coding object. A discrimination flag coding section 103 encodes an ON/OFF state of a flag of the full white block of the entire image from the discrimination section 102. Furthermore, an in-block coding section 104 encodes the picture element in the block by the prediction coding system. Furthermore, a memory section 33 stores coding data of the discrimination flag, stripe code length data and code data of the in-block picture element to be coded. A discrimination flag decoding section 107 decodes all white flags in the unit of blocks over the entire image. When the flag of the object block indicates a full white level, no rotation processing is conducted.

Abstract: PURPOSE:To stably isolate a copying form by providing a 1st layer made of a semiconductor material with a specific electrical resistance and a 2nd layer, and constituting such that an electrified particles are electrostatically attracted and transferred on the 2nd layer. CONSTITUTION:A conveyance belt 26 is composed of the 1st base layer 42 made of a semiconductor material with an electrical resistance of 10<10>-10<13>OMEGA-cm, and the 2nd surface layer 44 made of a material with an electrical resistance 10<10>OMEGA-cm or above. The base layer 42 functions as a resistance connecting a transfer charger 34 as a charge supply source and a grounding roller 30 as a charge buffer, stably holds a charge supplied from the transfer charger 34, and generates a potential required for transferring the toner particles on a photosensitive body. The surface layer 44 gives resistance so that the entry of the charge that the base layer 42 has to the form can be prevented effectively. The surface layer 44 polarizes the form with the aid of the true charge that the base layer 42 has. Electrostatic attraction arises between the polarized form and a polarization charge, and the form is attracted and held on the surface layer. Thus the form can be isolated stably.
