    摘要: A projection display comprises a display device (CRT) forming an image (M) for projection onto a display screen (700). A photo sensor (S) is adjacent to the display screen (700) and generates a first signal (Isen) responsive to a level of the projected image (M) illumination incident on the photo sensor (S). A detector (275) is coupled to receive the first signal (Isen) and generates an output signal (202) indicative of detecting the first signal (Isen). A source (Q2/D) of a predetermined detection threshold value (Iref) is coupled to the detector (275) for determining a threshold at which the detection of the first signal (Isen) occurs. Wherein the first signal (Isen) exceeds the predetermined detection threshold value (Iref), the detector (275) detects and generates the output signal (202) indicative of signal detection, and generates a second signal (Vlit) for coupling to the source (Q2/D) to change the predetermined detection threshold value (Iref).

    摘要: A projection television display apparatus comprises a display device (CRT) with an image (M) formed for projection and a display screen (700) for receiving the projected image (M). A plurality of photo sensors (S1-S8) are located adjacent to edges of the display screen (700) and each generates an output signal (Isen) responsive to an intensity of illumination by the projected image (M). A detector (275) with controllable detection threshold (Iref) is coupled to the photo sensors (S1-S8) for generating a signal (202) having a first state when the output signal (Isen) generated by each of the plurality photo sensors (S1-S8) is greater than the detection threshold (Iref), and a second state when the output signal (Isen) generated by each of said plurality photo sensors (S1-S8) is less than the detection threshold (Iref). A controller (301/900) is coupled to the display device (CRT) and to the detector (275) for setting the detection threshold (Iref) for the output signal (Isen) generated by each one of the plurality of photo sensors (S1-S8). In response to the signal (202) having the first state, the controller (301/900) moves the image (M) on the display device (CRT) to sequentially illuminate another one of the plurality of photo sensors (S1-S8).
