Abstract: The present invention relates to a compact display projector and a method of using it to project images under the control of image generating equipment, such as computers and television systems. An optical input device (10) is built into the projector (12) to enable optical control signals directed onto the projected image, to be discriminated for causing the image generating equipment to modify the projected image. A positionally adjusted mirror device (40) is disposed in optical alignment with the optical input device to reflect the optical control signals back thereto, whereby the optical input device is readily aligned with the projected image to monitor it for the occurrence of any optical control signals.

Abstract: A method and optical system auxiliary input calibration arrangement (10A) accurately and reliably discriminate between a user generated image and a video source generated image, such as one produced by a computer. The calibration arrangement includes amplifier devices (176a) for increasing the strength of a video information signal (178A) indicative of the video generated image, and a user generated auxiliary input signal (179A) indicative of an auxiliary input light image, without increasing spurious ambient light signals. A discrimination circuit (46A) generates a detection signal whenever the amplified information signals are greater than a predetermined reference level signal. The microprocessor (42A) controls the exposure time of the light sensing device and selects an appropriate level of amplification for the output signal from the sensing device to increase light sensitivity between the vieo source generated light images as compared to the user generated auxiliary light images. The optical auxiliary input arrangement (11B) accurately and reliably discriminates between user generated double click information without the need of the user being so steady of hand as to cause the auxiliary light information beam to illuminate the same precise location on the viewing surface during the double click operation.

Abstract: L'invention se rapporte à un procédé et à un équipement d'étalonnage de signaux d'entrée auxiliaires à système optique (10A) qui permettent d'établir de façon précise et fiable une discrimination entre une image générée par l'utilisateur et une image générée par une source vidéo, par exemple produite par un ordinateur. Cet équipement d'étalonnage comprend des dispositifs amplificateurs (176a) servant à accroître la force d'un signal d'informations vidéo (178A) indiquant l'image générée par source vidéo, et d'un signal d'entrée auxiliaire (179A) généré par l'utilisateur indiquant une image lumineuse d'entrée auxiliaire, sans augmenter les signaux lumineux ambiants parasites. Un circuit discriminateur (46A) produit un signal de détection chaque fois que les signaux d'informations amplifiés dépassent un signal de niveau de référence prédéterminé. Le microprocesseur (42A) commande le temps d'exposition du dispositif de photo-détection et sélectionne un niveau approprié d'amplification pour le signal de sortie provenant du dispositif de détection, afin d'accroître la sensibilité à la lumière des images lumineuses générées par la source vidéo par rapport aux images lumineuses auxiliaires générées par l'utilisateur. Cet équipement d'entrée auxiliaire optique (11B) permet d'établir de façon précise et fiable une discrimination entre des informations double cliquer générées par l'utilisateur, sans qu'il soit nécessaire que l'utilisateur répète avec la main un geste suffisamment identique au précédent pour que le faisceau lumineux d'informations auxiliaire éclaire exactement le même endroit sur la surface de visualisation qu'au moment du double cliquer.
