Abstract
A display device comprises a nonvolatile memory for storing an amount of adjustment obtained in a blanking adjustment most recently performed for a particular video signal, means for judging whether or not the particular video signal is inputted, means for masking a region defined by the amount of adjustment, obtained in the blanking adjustment, stored in the nonvolatile memory at a black level when the particular video signal is inputted, means for allowing the blanking adjustment based on a user operation only when the particular video signal is inputted, and means for updating the amount of adjustment, obtained in the blanking adjustment, stored in the nonvolatile memory, when it is changed by the user operation, to the changed amount of blanking adjustment.
Claims12
A display device comprising:
- a nonvolatile memory for storing an amount of adjustment obtained in a blanking adjustment most recently performed for a particular video signal;
- means for judging whether or not the particular video signal is inputted;
- means for masking a region defined by the amount of adjustment, obtained in the blanking adjustment, stored in the nonvolatile memory at a black level when the particular video signal is inputted;
- means for allowing the blanking adjustment based on a user input command operation only when the particular video signal is inputted;
- means for changing the amount of adjustment based on the user input command;
- and
- means for updating the amount of adjustment, obtained in the blanking adjustment, stored in the nonvolatile memory, when it is changed by the user input command operation, to the changed amount of blanking adjustment.
A display device comprising:
- a nonvolatile memory for storing an amount of adjustment obtained in a blanking adjustment most recently performed for a particular video signal;
- a circuit for judging whether or not the particular video signal is inputted;
- a circuit for masking a region defined by the amount of adjustment, obtained in the blanking adjustment, stored in the nonvolatile memory at a black level when the particular video signal is inputted;
- a circuit for allowing the blanking adjustment based on a user input command operation only when the particular video signal is inputted;
- a circuit for changing the amount of adjustment based on the user input command;
- and
- a circuit for updating the amount of adjustment, obtained in the blanking adjustment, stored in the nonvolatile memory, when it is changed by the user input command operation, to the changed amount of blanking adjustment.

- means for masking a region defined by the amount of adjustment, obtained in the blanking adjustment, stored in the nonvolatile memory at a black level when the particular video signal is inputted;
- means for allowing the blanking adjustment based on a user input command operation only when the particular video signal is inputted;
- means for on-screen displaying, at the time of the blanking adjustment, the current amount of blanking adjustment;
- and
- means for updating the current amount of blanking adjustment on-screen displayed, when it is changed by the user input command operation, to the changed amount of blanking adjustment as well as updating the amount of adjustment, obtained in the blanking adjustment, stored in the nonvolatile memory to the changed amount of blanking adjustment.
