Abstract
Abstract An image processing apparatus for outputting image data to a printing unit (8) comprises input means (3) for inputting data from an external unit; image data generating means for generating pixel image data in accordance with the input data; memory means (6) for storing the pixel image data; resolution converting means (7) for converting resolution of the pixel image data; and output means (8) for outputting the pixel image data whose resolution is converted by said resolution converting means (7). In the apparatus the image data generating means determines the resolution of the pixel image data when it is stored into the memory means (6) in accordance with a memory capacity of the memory means (6).

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
107 words
An image processing apparatus for outputting image data to a printing unit, comprising: input means for inputting data from an external unit; image data generating means for generating pixel image data in accordance with the input data; memory means for storing the pixel image data; resolution converting means for converting a resolution of the pixel image data; and output means for outputting the pixel image data whose resolution is converted by said resolution converting means, wherein the image data generating means determines the resolution of the pixel image data when it is stored into the memory means in accordance with a memory capacity of the memory means.
Claim 2
Dependent Claim
107 words
An image processing apparatus for outputting image data to a printing unit, comprising: input means for inputting data from an external unit; image data generating means for generating pixel image data in accordance with the input data; memory means for storing the pixel image data; resolution converting means for converting a resolution of the pixel image data; and output means for outputting the pixel image data whose resolution is converted by said resolution converting means, wherein the image data generating means determines the resolution of the pixel image data when it is stored into the memory means in accordance with a memory capacity of the memory means.
Claim 3
Dependent Claim
18 words
An apparatus according to claim 1, wherein the memory capacity of the memory means is changed by expanding.
Claim 4
Dependent Claim
66 words
An apparatus according to claim 1, wherein the resolution converting means determines the resolution of the pixel image data to be generated in a manner such that the resolution of the pixel image data which is generated from the output means is set to be constant irrespective of the resolution of the pixel image data when the pixel image data is stored in the memory means.
Claim 5
Dependent Claim
32 words
An apparatus according to claim 3, wherein the resolution converting means changes the resolution of the pixel image data so as to be equal to a recording resolution of the printing unit.
Claim 6
Dependent Claim
35 words
An apparatus according to claim 1, wherein the input means receives code data from an external unit and the image data generating means has means for generating a pattern corresponding to said input code data.
Claim 7
Dependent Claim
29 words
An apparatus according to claim 1, wherein the resolution converting means changes the resolution of the pixel image data by executing an interpolating process of the pixel image data.
Claim 8
Dependent Claim
21 words
An apparatus according to claim 6, wherein the resolution converting means executes a smoothing process when the interpolating process is performed.
Claim 9
Independent Claim
89 words
A method of generating pixel image data which is printed by a printing unit, comprising the steps of: inputting data from an external unit; generating pixel image data whose resolution is determined by a size of memory which is constructed so as to store the pixel image data; and converting, if necessary, the resolution of the pixel image data stored in the memory in a manner such that the resolution of the output pixel image data is independent on the resolution determined in the pixel image data generating step.
Claim 10
Independent Claim
89 words
A method of generating pixel image data which is printed by a printing unit, comprising the steps of: inputting data from an external unit; generating pixel image data whose resolution is determined by a size of memory which is constructed so as to store the pixel image data; and converting, if necessary, the resolution of the pixel image data stored in the memory in a manner such that the resolution of the output pixel image data is independent on the resolution determined in the pixel image data generating step.
Claim 11
Dependent Claim
22 words
A method according to claim 8, wherein in said resolution converting step, an interpolating process of the pixel image data is executed.
Claim 12
Dependent Claim
15 words
A method according to claim 8, wherein said resolution converting step includes a smoothing process.
Claim 13
Dependent Claim
36 words
A printing apparatus including means for storing an image to be printed, characterised in that the resolution of the image to be printed is controlled in dependence upon the available storage space in the storage means.
Claim 14
Dependent Claim
36 words
A printing apparatus including means for storing an image to be printed, characterised in that the resolution of the image to be printed is controlled in dependence upon the available storage space in the storage means.
Claim 15
Dependent Claim
36 words
Image processing apparatus including means for smoothing image data to reduce the resolution thereof, and means for selecting either the output of said smoothing means or unsmooth- ed image data in dependence upon a selection criterion.
Claim 16
Dependent Claim
36 words
Image processing apparatus including means for smoothing image data to reduce the resolution thereof, and means for selecting either the output of said smoothing means or unsmooth- ed image data in dependence upon a selection criterion.
Claim 17
Dependent Claim
17 words
Apparatus according to claim 12, in which the selection criterion is related to available image storage space.
Claim 18
Dependent Claim
47 words
Image processing apparatus comprising processing means and readable/writeable memory means, in which the memory means includes image storage space and working space for said processing means, and there are provided image processing means which are controlled in dependence upon the demarcation of space in said memory means.
Claim 19
Dependent Claim
47 words
Image processing apparatus comprising processing means and readable/writeable memory means, in which the memory means includes image storage space and working space for said processing means, and there are provided image processing means which are controlled in dependence upon the demarcation of space in said memory means.
