FACSIMILE EQUIPMENT
Document Type and Number:
Japanese Patent JPH02117268
Kind Code:
A
Abstract:
PURPOSE:To speed up processing required for from reading to encoding, even when the reading is executed to one picture element according to plural components information by encoding information for each read component by an encoding means almost simultaneously. CONSTITUTION:Video data (video R, G, B and BK) to correspond to respective colors are sent from a color scanner 100 for each line of an original picture synchronously with respective line synchronizing signals. For example, concerning red R, a controller 148 executes compressing and encoding with a prescribed algorithm while an R encoding part 106 takes in red/not red data with the timing of a video clock. Then, the data are accumulated through a signal line 110 to an R transmission memory 118. The encoding is samely executed by a same order concerning another chrominance component and data are respective accumulated to an exclusive G transmission memory 119, a B transmission memory 120 and a BK transmission memory 121. Namely, encoding parts 106-109 are provided for each chrominance component. Then, since the encoding parts can be simultaneously and parallely operated, the processing from the reading to the encoding can be executed at the high speed even when reading one picture element according to the plural component information.
