Abstract
Abstract A recording apparatus for receiving a page description language representing image date to be recorded and for recording an image includes a memory for storing a bit image data smaller than a one-page capacity, a recording unit for recording the bit image data stored in the memory, a unit for generating partial bit image data of an area corresponding to the memory on the basis of the input page description language, and a controller for storing the partial bit image data generated by the generating unit in the memory, and for causing the recording unit to repeat recording of the partial bit image data stored in the memory until on-page bit image data is recorded.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
115 words
A recording apparatus for receiving a page description language representing image data to be recorded and for recording an image, comprising: memory means for storing bit image data smaller than a one-page capacity; means for recording the bit image data stored in said memory means; means for generating partial bit image data of an area corresponding to said memory means on the basis of the input page description language; and control means for storing the partial bit image data generated by said generating means in said memory means, and for causing said recording means to repeat recording of the partial bit image data stored in said memory means until one-page bit image data is recorded.
Claim 2
Dependent Claim
115 words
A recording apparatus for receiving a page description language representing image data to be recorded and for recording an image, comprising: memory means for storing bit image data smaller than a one-page capacity; means for recording the bit image data stored in said memory means; means for generating partial bit image data of an area corresponding to said memory means on the basis of the input page description language; and control means for storing the partial bit image data generated by said generating means in said memory means, and for causing said recording means to repeat recording of the partial bit image data stored in said memory means until one-page bit image data is recorded.
Claim 3
Dependent Claim
20 words
An apparatus according to claim 1, wherein said control means includes an address management device for updating each partial area.
Claim 4
Dependent Claim
27 words
An apparatus according to claim 1, wherein said recording means injects an ink droplet from an opening by a behavior of heat energy, thereby recording the image.
Claim 5
Dependent Claim
17 words
An apparatus according to claim 3, wherein said recording means is capable of recording a full-color image.
Claim 6
Dependent Claim
30 words
An apparatus according to claim 1, wherein said generating means generates the one-page bit image datal but bit image data of unnecessary areas are not stored in said memory means.
Claim 7
Dependent Claim
32 words
An apparatus according to claim 31 wherein recovery processing of said recording means is performed until the next partial bit image data is recorded after the partial bit image data is recorded.
Claim 8
Dependent Claim
47 words
A recording method comprising the steps of: inputting a page description language representing image data to be recorded; generating and storing bit image data of a partial area smaller than one page; and repeatedly performing recording in units of partial areas until a one-page image is recorded.
Claim 9
Dependent Claim
47 words
A recording method comprising the steps of: inputting a page description language representing image data to be recorded; generating and storing bit image data of a partial area smaller than one page; and repeatedly performing recording in units of partial areas until a one-page image is recorded.
Claim 10
Dependent Claim
16 words
A method according to claim 7, wherein said method controls an address for updating said area.
Claim 11
Dependent Claim
23 words
A method according to claim 7, wherein the recording comprises injecting an ink droplet from an opening by a behavior of heat energy.
Claim 12
Dependent Claim
15 words
A method according to claim 9, wherein the step of performing recording comprises full-color recording.
Claim 13
Dependent Claim
38 words
A method according to claim 7, wherein the step of storing bit image data of the partial area comprises generating bit image data of one page and storing bit image data of the partial area of one page.
Claim 14
Dependent Claim
35 words
A method according to claim 7, further comprising the step of performing recovery processing of a recording unit until the next partial bit image data is recorded after the partial bit image data is recorded.
Claim 15
Dependent Claim
65 words
An apparatus according to claim 1, further comprising means for determining whether a large-capacity memory is connected, and wherein said control means performs the control when said determining means determines that said large-capacity memory is not connected to said apparatus, and stores the one-page bit image data in said large-capacity memory when said determining means determines that said large-capacity memory is connected to said apparatus.
Claim 16
Dependent Claim
38 words
An apparatus according to claim 13, wherein said recovery processing of said recording means is not performed during recording of the one-page bit image data when the bit image data from said large-capacity memory is to be recorded.
Claim 17
Dependent Claim
14 words
An apparatus according to claim 13, wherein said large-capacity memory is an extended RAM.
Claim 18
Dependent Claim
42 words
A method according to claim 7, further comprising the steps of determining whether a large-capacity memory is connected, and storing the bit map image data of one page in said large-capacity memory when it is determined that said large-capacity memory is connected.
Claim 19
Dependent Claim
39 words
A method according to claim 16, wherein the recovery processing of said recording unit is performed during recording of the bit image data of one page when the bit image data from said large-capacity memory is to be recorded.
Claim 20
Dependent Claim
19 words
An image output device having an output buffer sufficient only to store a portion of an output image page.
Claim 21
Dependent Claim
19 words
