Abstract
A display apparatus includes a resolution conversion unit for converting the resolution of an input image signal into a predetermined resolution and generating a sync signal synchronized with the converted image signal, a mixing unit for mixing an on-screen display signal synchronized with the sync signal and the converted image signal, and a display unit for displaying an image related to an image signal output from the mixing means in accordance with the sync signal.
Claims21
A display apparatus comprising:
- resolution converting means for converting the resolution of an input image signal into a predetermined resolution and generating a sync signal synchronized with the converted image signal;
- mixing means for mixing an on-screen display signal synchronized with the sync signal and the converted image signal, wherein said mixing means comprises generating means for generating a coefficient signal associated with the on-screen display signal, and multiplying means for multiplying the converted image signal by the coefficient signal;
- and
- display means for displaying an image related to an image signal output from said mixing means in accordance with the sync signal.
A display method comprising:
- a resolution conversion step of converting the resolution of an input image signal into a predetermined resolution and generating a sync signal synchronized with the converted image signal;
- a mixing step of mixing an on-screen display signal synchronized with the sync signal and the converted image signal, wherein said mixing step comprises a step of generating a coefficient signal associated with the on-screen display signal, and a step of multiplying the converted image signal by the coefficient signal;
- and
- a display step of displaying an image related to an image signal output in said mixing step in accordance with the sync signal.
A display apparatus comprising:
- resolution converting means for converting the resolution of an input image signal into a predetermined resolution and generating a sync signal synchronized with the converted image signal;
- mixing means for mixing an on-screen display signal synchronized with the sync signal and the converted image signal, wherein said mixing means comprises generating means for generating a first signal having a first predetermined level associated with the on-screen display signal and a second signal having a second predetermined level associated with the on-screen display signal, and selecting means for selectively outputting the converted image signal and the first and second signals;
- and
- display means for displaying an image related to an image signal output from said mixing means in accordance with the sync signal.
A display method comprising:
- a resolution converting step of converting the resolution of an input image signal into a predetermined resolution and generating a sync signal synchronized with the converted image signal;
- a mixing step of mixing an on-screen display signal synchronized with the sync signal and the converted image signal, wherein said mixing step comprises a step of generating a first signal having a first predetermined level associated with the on-screen display signal and a second signal having a second predetermined level associated with the on-screen display signal, and a step of selectively outputting the converted image signal and the first and second signals;
- and
- a display step of displaying an image related to an image signal output in said mixing step in accordance with the sync signal.
A display control apparatus comprising:
- input means for inputting an image signal;
- resolution converting means for converting the resolution of the image signal input by said input means into a predetermined resolution and for outputting a resolution converted image signal;
- mixing means for generating a coefficient signal associated with an on-screen display signal to be mixed with the resolution converted image signal and for mixing an on-screen display signal and the resolution converted image signal outputted from said resolution converting means by multiplying the resolution converted image signal by the coefficient signal;
- and
- output means for outputting a mixed image signal output from said mixing means to a display device so that an image related to the mixed image signal is displayed by said display device.
