Claims
- 1. 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.
- 2. 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.
- 3. An apparatus according to claim 2, wherein said switching means preferentially performs display by said display control means.
- 4. 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.
- 5. An apparatus according to claim 1, wherein said detecting means detects an information rewritten portion of said storage means.
- 6. 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.
- 7. 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.
- 8. An apparatus according to claim 7, wherein said switching means preferentially performs display by said display control means.
- 9. 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.
- 10. An apparatus according to claim 6, wherein said detecting means detects an information rewritten portion of said storage means.
- 11. 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.
