The intelligent projector provided by the application specifically can comprise: fig. 3 is a schematic diagram of a projection system according to an embodiment of the invention, and fig. 3 is a schematic diagram. The projection system includes a projection surface S1 and a projection device 104. The projection device 104 may include a light source 106, a light valve 108, an integrator rod 110, a storage unit 112, a control unit 114, and an image source signal combining unit 116. The control unit 114 couples the light valve 108, the storage unit 112 and the image source signal combining unit 116, and the storage unit 112 may be configured to store Extended Display Identification Data (EDID), where the Extended Display Identification Data may include information such as the highest resolution, the scanning frequency, and the manufacturer name and serial number that can be supported by the projection apparatus 104. The projection device 104 is coupled to the host 102, wherein the host 102 may be an electronic device such as a computer, a tablet computer, or a mobile phone capable of providing image data.
In addition, the video source signal combining unit 116 can simultaneously receive a plurality of video source signals from the host 102, the video source signals representing sources having output video frames, not limited to a single host 102 or a plurality of hosts, and combine and convert the video source signals into a combined video signal, wherein the video frame corresponding to the combined video signal is formed by splicing a plurality of video frames corresponding to the plurality of video source signals. For example, the ratio of the projection presented by the two original image source signals is 4: 3, the combined projection ratio of the combined image frame generated by the image source signal combining unit 116 is 16: 6, but not limited to, the operator can define the desired combined projection ratio of the combined image frames. In addition, the plurality of images of the plurality of image source signals have different projection ratios or resolutions, and can be combined by the image source signal combining unit 116 according to a desired projection ratio preset by a user to generate a combined projection ratio of the combined image. When the projection apparatus 104 is connected to the host 102, the host 102 requests the projection apparatus 104 to provide the extended display identification data, and the control unit 114 in the projection apparatus 104 can provide the extended display identification data stored in the storage unit 112 to the host 102, so that the host 102 provides a plurality of projection ratios corresponding to the image source signals, and the image source signal combination unit 116 combines the projection ratios corresponding to the image source signals to form a combined projection ratio, which corresponds to a combined image signal of the combined projection ratio to be projected. For example, in this embodiment, the projection device 104 is used to project an ultra-wide image frame (combined image frame) with an ultra-wide projection ratio (combined projection ratio), which is formed by splicing image frames corresponding to a plurality of image source signals, where the ultra-wide image frame is an image frame with an ultra-wide projection ratio, which may be, for example, 2.3: 1 to 2.7: 1, wherein the optimal ultra-wide projection ratio is 16: 6 or 21: 9, however, it is not limited thereto.
The light source 106 is used to provide an illumination beam, and the light source 106 may be implemented as, for example, a light emitting diode, a laser light source, or a high pressure mercury lamp, however, it is not limited thereto. The integrating rod 110 is disposed in the transmission path of the illumination beam and between the light source 106 and the light valve 108.
The integrating rod 110 has an incident end and an exit end, and the integrating rod 110 can receive the illumination beam from the light source 106 from the incident end and output the illumination beam from the exit end, wherein the area of the incident end of the integrating rod 110 is larger than that of the exit end, and the aspect ratio of the exit end conforms to the ultra-wide projection ratio, so that the illumination beam can be more concentrated, thereby effectively increasing the projection brightness and improving the projection quality. It should be noted that in other embodiments, the area of the light-input end of the integrating rod 110 may be equal to the area of the light-output end, and is not limited to this embodiment.
The light valve 108 may be, for example, a Digital micro-mirror Device (dmd) or a Liquid Crystal on silicon (Liquid Crystal panel 1), and the light valve 108 is disposed in the transmission path of the illumination beam. The illumination beam is output from the light output end of the integrating rod 110 and then enters the light valve 108. The light valve 108 has a light receiving surface, and the control unit 114 can control the light receiving surface of the light valve 108 according to the image signal provided by the host 102 or the combined image signal provided by the image source signal combining unit 116, so as to convert the illumination beam incident on the light receiving surface into an image beam, and project the image beam onto the projection surface S1, so as to form an ultra-wide image frame. The projection surface S1 may be a screen including Fresnel lens film (Fresnel 1ens film) for directing the projection beam to the viewer to improve color gain and contrast, or the projection surface S1 may be a screen with a wiping feature. The screen may be, for example, a smart glass, which may be transparent or fog white depending on the applied voltage, and thus may be used as a projection screen, in other words, the screen may be a reflective or transmissive screen.
In addition, the storage unit 112 may also store a resolution mode lookup table for storing the ultra-wide image resolution, for example: 1920 × 720, 1280 × 550, and 2560 × 1080, but the required resolution may be set by a manufacturer. When the control unit 114 controls the light receiving surface of the light valve 108 according to the combined image signal to convert the light valve 108 into the illumination beam, the mode corresponding to the ultra-wide projection ratio can be searched according to the resolution mode lookup table stored in the storage unit 112, and the light valve 108 is set to the mode corresponding to the ultra-wide projection ratio (or resolution), so as to determine that the image signal format provided by the host 102 is compatible with the projection apparatus 104. When the light valve 108 is set to the mode corresponding to the ultra-wide projection ratio, the control unit 114 disables a partial area of the light receiving surface of the light valve 108, so that the non-disabled area of the light receiving surface conforms to the ultra-wide projection ratio, and the non-disabled area of the light receiving surface can be used for receiving the illumination light beam from the light emitting end of the integrator rod 110, wherein when the control unit 114 is disabled, for example, when the light valve is a digital micromirror device, the light receiving surface of the light valve is controlled by an electrical signal to disable the digital micromirror in the partial area, so that the illumination light beam is not projected to the projection surface through the wide-angle lens; for example, when the light valve is a liquid crystal on silicon panel, the control unit 114 disables the electric signal to control the liquid crystal molecules in the partial area of the light receiving surface of the light valve, so that the illumination beam cannot penetrate or reflect to form the image beam, and thus, by disabling the partial area of the light receiving surface of the light valve 108, the image beam corresponding to the area a1 where no projection is performed can be shielded, and the ratio of the projection image is ensured to conform to the ultra-wide projection ratio.
Optionally, the navigation path obtained by the intelligent projector and sent by the mobile phone may be a plurality of navigation paths, the intelligent projector collects a first picture, identifies the first picture to determine a first identity corresponding to the first picture, determines the preference of the user according to the first identity, and selects one navigation path from the plurality of navigation paths according to the preference of the user.
