7. A method for controlling a fuel metering system, comprising:
controlling a fuel pressure as a function of an operating state of an internal combustion engine, the fuel pressure being controlled at a first value if the internal combustion engine is switched off, and the fuel pressure being controlled at a second value if a condition of the fuel pressure is present which is normal when an internal combustion engine is switched off.
8. The method according to claim 7, wherein the first value is used at idle.
9. The method according to claim 7, wherein the fuel pressure is controlled at the second value if the fuel pressure falls below a threshold value.
10. The method according to claim 7, wherein the fuel pressure is controlled at the second value if a vehicle driven by the internal combustion engine is switched off.
11. The method according to claim 7, wherein the fuel pressure is set to an operating point-dependent value if a rotational speed rises above a specific rotational speed value.
12. A device for controlling a fuel metering system, a fuel pressure being a function of an operating state of an internal combustion engine, the device comprising:
means for controlling the fuel pressure at a first value when the internal combustion engine is switched off and for controlling the fuel pressure at a second value when a condition is present which is normal when an internal combustion engine is switched off.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A display apparatus, comprising:
a receiving unit which receives a video signal;
a video processing unit which performs video processing on the received video signal and generates a processed video signal;
a display unit which displays a video based on the processed video signal;
an image taking unit which takes an image of a subject and generates an image information; and
a control unit which controls the video processing unit to change at least one property of the video being displayed in the display unit based on the image information.
2. The display apparatus according to claim 1, wherein the at least one property of the video comprises at least one of a brightness of the video and a color temperature of the video.
3. The display apparatus according to claim 1, wherein the image taking unit comprises:
a charge coupled device (CCD) which changes an optical image of the subject into an analog video signal;
a corrected double samplingautomatic gain control (CDSAGC) unit which processes the analog video signal;
an analog to digital converter which converts the analog video signal into a digital video signal; and
a digital signal processor which processes the digital video signal and generates the image information which corresponds to the image of the subject.
4. The display apparatus according to claim 1, wherein the control unit generates a background image information which corresponds to a background separated from the image of the subject, and changes the at least one property of the video based on the background image information which is generated.
5. The display apparatus according to claim 4, wherein the control unit changes the at least one property of the video based on a brightness information included in the background image information.
6. The display apparatus according to claim 5, wherein the control unit extracts the brightness information at a predetermined interval of time.
7. The display apparatus according to claim 1, wherein the control unit calculates an average brightness of each frame from the image information, and changes the at least one property of the video based on the average brightness which is calculated.
8. The display apparatus according to claim 1, further comprising a communicating unit,
wherein the control unit controls the communicating unit to transmit the image information which corresponds to the image of the subject which is taken by the image taking unit to an external apparatus.
9. A video adjusting method of a display apparatus which comprises an image taking unit which takes an image of a subject to generate an image information, the method comprising:
generating the image information through the image taking unit; and
changing at least one property of a video being displayed in the display apparatus based on the image information which is generated.
10. The video adjusting method of the display apparatus according to claim 9, wherein the at least one property of the video comprises at least one of a brightness of the video and a color temperature of the video.
11. The video adjusting method of the display apparatus according to claim 9, wherein the generating the image information comprises generating a background image information which corresponds to a background separated from the image of the subject, and
the changing the at least one video property of the video comprises changing the property of the video based on the background image information which is generated.
12. The video adjusting method of the display apparatus according to claim 11, wherein the changing the at least one property of the video comprises changing the at least one property of the video based on a brightness information included in the background image information.
13. The video adjusting method of the display apparatus according to claim 12, wherein the generating the image information comprises calculating an average brightness of each frame from the image information, and
the changing the at least one property of the video comprises changing the at least one property of the video based on the average brightness which is calculated.
14. The video adjusting method of the display apparatus according to claim 12, wherein the changing the at least one property of the video comprises extracting the brightness information from the background image information at an interval of time.
15. The video adjusting method of the display apparatus according to claim 9, wherein the generating the image information comprises transmitting the image information to an external apparatus.
