Title:
画像形成装置
Document Type and Number:
Japanese Patent JP6984413
Kind Code:
B2
Abstract:
An ASIC includes: a communication circuit that communicates with a control circuit; a multi-level, fixed-length compression circuit that performs fixed-length compression on scanner-generated image data to output multi-level, fixed-length compressed image data; a tone processing circuit that performs tone processing on the scanner-generated image data to output reduced-level image data; a first selection circuit that selects one of the multi-level, fixed-length compressed image data and the reduced-level image data, as first selected image data to be transmitted by the communication circuit to the control circuit; a multi-level, fixed-length decompression circuit that performs fixed-length decompression on image data received by the communication circuit from the control circuit, to output fixed-length decompressed image data; and a second selection circuit that selects one of the fixed-length decompressed image data and the image data received by the communication circuit, as second selected image data to be output to the plotter.
