Abstract

Abstract An image forming apparatus and an electronic device for outputting data to the image forming apparatus. The image forming apparatus comprises an interface for inputting single bit image data and a command from an external device, a first store for storing the single bit image data, a second store for receiving and storing color data for coloring the single bit image data, and an image forming device for forming a color image on the basis of the data in the first and second stores. The electronic device includes a first output for outputting single bit image data, a second output for outputting a color number for one pixel of color image data, and a third output for outputting both first multi-level color component data for the single bit image data and second multi-level color component data for the color number.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 110 words
An image forming apparatus comprising: a) interface means for inputting single bit image data and a command from an external device, the single bit image data being image data in which a single bit corresponds to one pixel of an image; b) first means for storing the single bit image data input from the external device by said interface means; c) second means for receiving and storing color data for coloring the single bit image data input by said interface means; and d) means for forming a color image on the basis of the single bit image data from said first means and the color data from said second means.
Claim 2
Dependent Claim 110 words
An image forming apparatus comprising: a) interface means for inputting single bit image data and a command from an external device, the single bit image data being image data in which a single bit corresponds to one pixel of an image; b) first means for storing the single bit image data input from the external device by said interface means; c) second means for receiving and storing color data for coloring the single bit image data input by said interface means; and d) means for forming a color image on the basis of the single bit image data from said first means and the color data from said second means.
Claim 3
Dependent Claim 14 words

Claim 4
Dependent Claim 23 words
An apparatus according to claim 1, wherein said first means comprises means for storing the single bit image data as a bit map.
Claim 5
Dependent Claim 13 words
An apparatus according to claim 1, wherein said second means comprises a table.
Claim 6
Dependent Claim 18 words
An apparatus according to claim 1, wherein said means for forming a color image comprises an electrophotographic printer.
Claim 7
Dependent Claim 15 words
An apparatus according to claim 1, wherein said color data is designated by said device.
Claim 8
Dependent Claim 27 words
An apparatus according to claim 6, wherein said apparatus performs transmission and reception processing of the single bit image data with said external apparatus by bidirectional communication.
Claim 9
Dependent Claim 80 words
An electronic device for outputting data to a color image forming apparatus, comprising: a) first output means for outputting single bit image data in which a single bit corresponds to one pixel of an image; b) second output means for outputting color data for one pixel of color image data; and c) third output means for outputting first multi-level color component data for the single bit image data and for outputting second multi-level color component data for the color data.
Claim 10
Dependent Claim 80 words
An electronic device for outputting data to a color image forming apparatus, comprising: a) first output means for outputting single bit image data in which a single bit corresponds to one pixel of an image; b) second output means for outputting color data for one pixel of color image data; and c) third output means for outputting first multi-level color component data for the single bit image data and for outputting second multi-level color component data for the color data.
Claim 11
Dependent Claim 42 words
A device according to claim 8, further comprising: d) interface means for outputting one of the single bit image data output by said first output means and the color data output by said second output means to said color image forming apparatus.
