Abstract
Abstract A decoding processing is executed in a multiple processing at high speed with a simple construction or control in a manner such that the image memory 11 stores an input compressed code, the multiplexer 14 selects the compressed code shift circuit 12 or 13 where the compressed code is shifted, and the decoder 15 decodes the shifted compressed-code.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
165 words
An image processing apparatus, comprising: first input means for inputting a line at a time first image data representing a first page of an image; second input means for inputting a line at a time second image data representing a second page of an image; first selection means for alternately selecting a line at a time one of the first and second image data input a line at a time by said first and second input means; second selection means for selecting one of first and second parameters corresponding to one of the first and second image data selected by said first selection means; and; processing means for alternately processing a line at a time the first and second image data selected by said first selection means by using the first and second parameters selected by said second selection means, wherein said first selection means switches between the first and second image data whenever one line of image data is processed by said processing means.
Claim 2
Dependent Claim
165 words
An image processing apparatus, comprising: first input means for inputting a line at a time first image data representing a first page of an image; second input means for inputting a line at a time second image data representing a second page of an image; first selection means for alternately selecting a line at a time one of the first and second image data input a line at a time by said first and second input means; second selection means for selecting one of first and second parameters corresponding to one of the first and second image data selected by said first selection means; and; processing means for alternately processing a line at a time the first and second image data selected by said first selection means by using the first and second parameters selected by said second selection means, wherein said first selection means switches between the first and second image data whenever one line of image data is processed by said processing means.
Claim 3
Dependent Claim
22 words
An apparatus according to claim 1, wherein said processing means encodes the first and second image data a line at a time.
Claim 4
Dependent Claim
55 words
The apparatus according to claim 1, further comprising: memory means for storing first and second image data representing first and second pages of images, respectively, wherein said first input means inputs the first image data stored in said memory means and said second input means inputs the second image data stored in said memory means.
Claim 5
Dependent Claim
26 words
An apparatus according to claim 1, wherein said processing means processes the first and second image data in accordance with first and second synchronizing signals, respectively.
Claim 6
Dependent Claim
31 words
An apparatus according to claim 3, wherein said memory mean stores the first and second processed image data obtained by processing the first and second image data by said processing means.
Claim 7
Dependent Claim
174 words
An image processing method consisting of the steps of: a first inputting step for inputting a line at a time first image data representing a first page of an image; a second inputting step for inputting a line at a time second image data representing a second page of an image; a first selecting step for alternately selecting a line at a time one of the first and second image data input a line at a time by the first and second inputting steps; a second selecting step for selecting one of first and second parameters corresponding to one of the first and second image data selected by the first selecting step; and a processing step for alternately processing a line at a time the first and second image data selected by the first selecting step by using the first and second parameters selected by the second selecting step; wherein the first selecting step switches between the first and second image data whenever one line of image data is processed by said processing step.
Claim 8
Dependent Claim
174 words
An image processing method consisting of the steps of: a first inputting step for inputting a line at a time first image data representing a first page of an image; a second inputting step for inputting a line at a time second image data representing a second page of an image; a first selecting step for alternately selecting a line at a time one of the first and second image data input a line at a time by the first and second inputting steps; a second selecting step for selecting one of first and second parameters corresponding to one of the first and second image data selected by the first selecting step; and a processing step for alternately processing a line at a time the first and second image data selected by the first selecting step by using the first and second parameters selected by the second selecting step; wherein the first selecting step switches between the first and second image data whenever one line of image data is processed by said processing step.
Claim 9
Dependent Claim
24 words
The image processing method according to claim 6, wherein the processing step encodes the first and second image data a line at a time.
Claim 10
Dependent Claim
58 words
The image processing method according to claim 6, further comprising: a storage step for storing first and second image data representing first and second pages of images, respectively, wherein the first inputting step inputs the first image data stored in the storage step and the second inputting step inputs the second image data stored in the storage step.
Claim 11
Dependent Claim
28 words
The image processing method according to claim 6, wherein the processing step processes the first and second image data in accordance with first and second synchronizing signals, respectively.
Claim 12
Dependent Claim
32 words
The image processing method according to claim 8, wherein the storage step stores first and second processed image data obtained by processing the first and second image data by the processing step.
