Abstract

Abstract A display control apparatus includes a memory for storing information supplied from a processing apparatus, a detector for detecting a storage portion of the information, a display controller for performing display on a display device on the basis of the information stored in the portion detected by the detector, and a limiting unit for limiting the portion detected by the detector.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 169 words
A display control apparatus comprising: storage means for storing information supplied from a processing apparatus; detecting means for detecting a storage portion of the information; first flag means comprising a plurality of flags each corresponding to one storage portion detected by said detecting means; second flag means comprising a plurality of mask flags corresponding to each flag of said first flag means; flag setting means for setting at least one of the plurality of flags on the basis of a detection result by said detecting means; area setting means for setting at least one of the plurality of mask flags of said second flag means so as to set an extent in the plurality of flags; checking means for checking whether or not each of the flags of said first flag means and said second flag means is set; and display control means for performing display on a display device on the basis of the information stored in said storage means and a checking result of said checking means.
Claim 2
Dependent Claim 169 words
A display control apparatus comprising: storage means for storing information supplied from a processing apparatus; detecting means for detecting a storage portion of the information; first flag means comprising a plurality of flags each corresponding to one storage portion detected by said detecting means; second flag means comprising a plurality of mask flags corresponding to each flag of said first flag means; flag setting means for setting at least one of the plurality of flags on the basis of a detection result by said detecting means; area setting means for setting at least one of the plurality of mask flags of said second flag means so as to set an extent in the plurality of flags; checking means for checking whether or not each of the flags of said first flag means and said second flag means is set; and display control means for performing display on a display device on the basis of the information stored in said storage means and a checking result of said checking means.
Claim 3
Dependent Claim 49 words
An apparatus according to claim 1, further comprising display updating means and switching means, said updating means performing display on the display device on the basis of all information stored in said storage means, and said switching means switching between said display control means and said display updating means.
Claim 4
Dependent Claim 18 words
An apparatus according to claim 2, wherein said switching means preferentially performs display by said display control means.
Claim 5
Dependent Claim 38 words
An apparatus according to claim 2, further comprising counting means for counting a number of portions detected by said detecting means, and wherein said switching means performs switching on the basis of a count from said counting means.
Claim 6
Dependent Claim 19 words
An apparatus according to claim 1, wherein said detecting means detects an information rewritten portion of said storage means.
Claim 7
Dependent Claim 190 words
A display control apparatus comprising: display means for displaying information; storage means for storing information displayed on said display means; supply means for supplying the information stored in said storage means; detecting means for detecting a portion for storing the information supplied from said supply means; first flag means comprising a plurality of flags each corresponding to one storage portion detected by said detecting means; second flag means comprising a plurality of mask flags corresponding to each flag of said first flag means; flag setting means for setting at least one of the plurality of flags on the basis of a detection result by said detecting means; area setting means for setting at least one of the plurality of mask flags of said second flag means so as to set an extent in the plurality of flags; checking means for checking whether or not each of the flags of said first flag means and said second flag means is set; and display control means for performing display on said display means on the basis of the information stored in said storage means and a checking result of said checking means.
Claim 8
Dependent Claim 190 words
A display control apparatus comprising: display means for displaying information; storage means for storing information displayed on said display means; supply means for supplying the information stored in said storage means; detecting means for detecting a portion for storing the information supplied from said supply means; first flag means comprising a plurality of flags each corresponding to one storage portion detected by said detecting means; second flag means comprising a plurality of mask flags corresponding to each flag of said first flag means; flag setting means for setting at least one of the plurality of flags on the basis of a detection result by said detecting means; area setting means for setting at least one of the plurality of mask flags of said second flag means so as to set an extent in the plurality of flags; checking means for checking whether or not each of the flags of said first flag means and said second flag means is set; and display control means for performing display on said display means on the basis of the information stored in said storage means and a checking result of said checking means.
Claim 9
Dependent Claim 49 words
An apparatus according to claim 6, further comprising display updating means and switching means, said updating means performing display on said display device on the basis of all information stored in said storage means, and said switching means switching between said display control means and said display updating means.
Claim 10
Dependent Claim 18 words
An apparatus according to claim 7, wherein said switching means preferentially performs display by said display control means.
Claim 11
Dependent Claim 38 words
An apparatus according to claim 7, further comprising counting means for counting a number of portions detected by said detecting means, and wherein said switching means performs switching on the basis of a count from said counting means.
Claim 12
Dependent Claim 19 words
An apparatus according to claim 6, wherein said detecting means detects an information rewritten portion of said storage means.
Claim 13
Dependent Claim 142 words
A display control method comprising the steps of: storing information supplied from a processor into a memory; detecting a storage portion of the information from a specific range; providing a plurality of first flags each corresponding to one of the detected storage portions; providing a plurality of mask flags corresponding to each of the first flags; setting at least one of the plurality of flags based on the detected storage portion; setting at least one of the plurality of mask flags so as to set an extent in the plurality of flags; checking whether or not each of the flags and the mask flags in the extent is set; and performing a display on a display device on the basis of the information stored in a storage area and the results of checking the flags and the mask flags in the extent.
Claim 14
Dependent Claim 142 words
A display control method comprising the steps of: storing information supplied from a processor into a memory; detecting a storage portion of the information from a specific range; providing a plurality of first flags each corresponding to one of the detected storage portions; providing a plurality of mask flags corresponding to each of the first flags; setting at least one of the plurality of flags based on the detected storage portion; setting at least one of the plurality of mask flags so as to set an extent in the plurality of flags; checking whether or not each of the flags and the mask flags in the extent is set; and performing a display on a display device on the basis of the information stored in a storage area and the results of checking the flags and the mask flags in the extent.
