Abstract
Abstract When outputting color images bit-mapped in each color to a plurality of output memories according to record information, a flag set in each color by a prescribed range for identifying whether to draw a bit-mapped image in the corresponding output memory is memorized and stored, so that the flag is referred to before each output memory is cleared at each time of bit mapping, and so that determination is made as to whether to clear the output memory.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
126 words
An output control apparatus comprising: drawing means for drawing an image on a memory based on data received from an external apparatus; clearing means for executing a memory clear process on the memory; discriminating means for discriminating whether an image has been drawn on the memory by said drawing means; and control means for controlling said clearing means not to execute the memory clear process prior to drawing of a new image by said drawing means if said discriminating means discriminates that no image has been drawn on the memory, and controlling said clearing means to execute the memory clear process prior to drawing of a new image by said drawing means if said discriminating means discriminates that an image has been drawn on the memory.
Claim 2
Dependent Claim
126 words
An output control apparatus comprising: drawing means for drawing an image on a memory based on data received from an external apparatus; clearing means for executing a memory clear process on the memory; discriminating means for discriminating whether an image has been drawn on the memory by said drawing means; and control means for controlling said clearing means not to execute the memory clear process prior to drawing of a new image by said drawing means if said discriminating means discriminates that no image has been drawn on the memory, and controlling said clearing means to execute the memory clear process prior to drawing of a new image by said drawing means if said discriminating means discriminates that an image has been drawn on the memory.
Claim 3
Dependent Claim
46 words
An output control apparatus according to claim 1, wherein said drawing means draws an image on the memory by turning on bits of the memory corresponding to the image and wherein said clearing means executes the memory clear process by turning bits of the memory off.
Claim 4
Dependent Claim
27 words
An output control apparatus according to claim 1, further comprising print means for printing data based on the image drawn on the memory by said drawing means.
Claim 5
Dependent Claim
17 words
An output control apparatus according to claim 3, wherein said print means comprises an ink jet printer.
Claim 6
Dependent Claim
87 words
An output control apparatus according to claim 1, wherein said discriminating means performs a discrimination process using a flag which is turned on after an image has been drawn on the memory by said drawing means, and wherein said control means controls said clearing means not to execute the memory clear process prior to drawing of a new image if the flag is off and controls said clearing means to execute the memory clear process prior to drawing of a new image if the flag is on.
Claim 7
Dependent Claim
19 words
An output control apparatus according to claim 1, wherein the memory comprises memory sections corresponding to respective color components.
Claim 8
Independent Claim
131 words
A method executed by an output control apparatus comprising drawing means for drawing an image on a memory based on data received from an external apparatus, and clearing means for executing a memory clear process on the memory, said method comprising the steps of: discriminating whether an image has been drawn on the memory by the drawing means; and controlling the clearing means not to execute the memory clear process prior to drawing of a new image by the drawing means if said discriminating step discriminates that no image has been drawn on the memory, and controlling the clearing means to execute the memory clear process prior to drawing of a new image by the drawing means if said discriminating step discriminates that an image has been drawn on the memory.
Claim 9
Independent Claim
131 words
A method executed by an output control apparatus comprising drawing means for drawing an image on a memory based on data received from an external apparatus, and clearing means for executing a memory clear process on the memory, said method comprising the steps of: discriminating whether an image has been drawn on the memory by the drawing means; and controlling the clearing means not to execute the memory clear process prior to drawing of a new image by the drawing means if said discriminating step discriminates that no image has been drawn on the memory, and controlling the clearing means to execute the memory clear process prior to drawing of a new image by the drawing means if said discriminating step discriminates that an image has been drawn on the memory.
Claim 10
Dependent Claim
44 words
A method according to claim 7, wherein the drawing means draws an image on the memory by turning on bits of the memory corresponding to the image and wherein the clearing means executes the memory clear process by turning bits of the memory off.
Claim 11
Dependent Claim
25 words
A method according to claim 7, further comprising the step of printing data based on the image drawn on the memory by the drawing means.
Claim 12
Dependent Claim
18 words
A method according to claim 9, wherein said printing step prints the data using an ink jet printer.
Claim 13
Dependent Claim
85 words
A method according to claim 7, wherein said discriminating step performs a discrimination process using a flag which is turned on after an image has been drawn on the memory by the drawing means, and wherein said controlling step controls the clearing means not to execute the memory clear process prior to drawing of a new image if the flag is off and controls the clearing means to execute the memory clear process prior to drawing of a new image if the flag is on.
Claim 14
Dependent Claim
17 words
A method according to claim 7, wherein the memory comprises memory sections corresponding to respective color components.
Claim 15
Dependent Claim
140 words
A computer-readable memory medium for storing a program for a method executed by an output control apparatus comprising drawing means for drawing an image on a memory based on data received from an external apparatus, and clearing means for executing a memory clear process on the memory, said method comprising the steps of: discriminating whether an image has been drawn on the memory by the drawing means; and controlling the clearing means not to execute the memory clear process prior to drawing of a new image by the drawing means if said discriminating step discriminates that no image has been drawn on the memory, and controlling the clearing means to execute the memory clear process prior to drawing of a new image by the drawing means if said discriminating step discriminates that an image has been drawn on the memory.
Claim 16
Dependent Claim
140 words
A computer-readable memory medium for storing a program for a method executed by an output control apparatus comprising drawing means for drawing an image on a memory based on data received from an external apparatus, and clearing means for executing a memory clear process on the memory, said method comprising the steps of: discriminating whether an image has been drawn on the memory by the drawing means; and controlling the clearing means not to execute the memory clear process prior to drawing of a new image by the drawing means if said discriminating step discriminates that no image has been drawn on the memory, and controlling the clearing means to execute the memory clear process prior to drawing of a new image by the drawing means if said discriminating step discriminates that an image has been drawn on the memory.
Claim 17
Dependent Claim
45 words
