Field of the Invention 10 15 The present invention relates to a display image generating technology with different brightness. [# 支 4 标 U Background of the Invention There are various technologies available on the market to display images. One of these proposals was completed through the use of digital projectors. Typically, these video cameras are configured to have a fixed full range (gamm). In this article, the full range refers to the range of color_spectrum power distribution, and includes specific color correction such as hue, sat, and intensity or brightness. For such a fixed and full-range projector, it typically has a full range that is more suitable for displaying image images or more suitable for displaying dynamic images. ^ In this regard, the full range of hidden images will be sacrificed for chroma to include; towards brightness (for example, higher intensity white spots), or chroma. Conversely, it is used to include higher chroma at the expense of brightness for the full range of inactive images. The use of an early-fixed, full-range projector to display dynamic images will therefore result in a reduction in mouth muzzle similar to that of the image, or the image quality of two images. Both are reduced results. Therefore, a number of fixed. Full-range projectors are sometimes used (to achieve static) 20 1230009 high-quality image display. However, purchasing a plurality of fixed-full range projectors is undesirable because such projection opportunities are expensive. Furthermore, even with multiple fixed-to-range projectors, the quality of mixed media images (for example, image images and motion pictures in the same presentation) is impaired. [Summary of the Invention] Summary of the Invention A method for generating a display image includes receiving image information representing an image to be displayed, generating an image formed by a plurality of images of different colors, and projecting the generated image along an optical path. image. The 10 different color images have a color intensity related to the energy applied to a light source. The level of energy is applied to the light source during the generation of an image of one color, and the level of the energy is different from the level of energy applied to the light source during the generation of an image of another color.

I: Embodiment 3 Detailed description of the preferred embodiment 10 First, referring to FIG. 1, a display system 30 of an embodiment of the present invention is displayed. The display system 30 may be any suitable system suitable for displaying an image formed by different color images, including, but not limited to, a rear-projection display system, a front-projection display system, and an internal display screen or other display surface. Projector. These display systems can use overhead projectors, active liquid crystal display (LCD) projection devices, including liquid crystal on silicon (LCOS), other spatial light modulators, and micro-mirror-based projection scenes & gt Installation. The images that are projected or displayed can include still images, like images, crosswords, diagrams, 20s, and photos, and generated by computers, like video games and cartoon films, received like broadcast television signals, or A motion picture produced by a charge-coupled element (CCD), like a camera. Therefore, this detailed description is not limited to the use of any particular type of image, or the source of the image data. The image data or information can be transmitted through a corresponding data link, such as Figure 1230009. Image port, universal serial bus (USB), infrared connection, S-video port, component, composite ), HDTV, or any link that transmits image information to receive from an image information or data source 32. The image data can be transferred to an image display generator 34, which can function as a device for generating a plurality of different color images. The display generator 34 may display the images or project the images for display. The display generator may include a light source, a color generating device or other color source, a colored image source, an optics, a stereo light modulator, a focusing device, a controller, or a processor. 10 Different color images can be directed to relevant parts along an optical path. The display device can then be projected for display or display a composite color image formed from different color images. The composite image may be formed from one or more different color images and may be an image perceived by a viewer. These different color images can be projected along a common optical path or on 15 separate optical paths, and they can be projected continuously or simultaneously. A condition identifier 36 may identify one or more conditions related to the display of the image acting by the display system. Therefore, a means for recognizing the display condition of an image is provided. The condition can be based on the information received by the system, like external or user input information, received data, like image data or information, or information obtained by the system, like ambient light conditions, or displayed. The image looks like it, to be recognized. The display system can produce different color images for display with optical characteristics based on the identified display conditions. The condition identifier can include input / 1230009 output devices, sensors, detectors, sensors, switches, selectors, analyzers, processors, or controllers. A display system 40, which may be an embodiment of the display system 30, is shown in FIG. An image display generator 42 may include five processors or controllers 44 connected to a color image generator 46 and a display device 48. The color image generator can also be regarded as an image source and a device for generating different color images. The color image generator 46 may include a color light source or color source 50, which may include a light source 52 and a color generator 54. 10 The light source may be any suitable light source suitable for optically generating and directing light along an optical path 56, including a single white light source, such as mercury, plasma, incandescent, laser, and beacon, or a plurality of White or single color light source, like laser diode, light emitting diode (LED), LED array, or other solid-state source or source array. The light source may include a lens for controlling, focusing, and directing the light along the optical path. In addition, the color source may include one or more lamps or light emitting devices that emit colored light, like a laser light source. The color generator can operate according to one or more of the following principles: interference, refraction, diffraction, absorption, reflection, or scattering. It can include items such as diffractive optical surfaces that divide light into usable spectral components or components of 20 colors, refractive prisms, absorbing materials, and transmissive or reflective films that interfere with color filters. The image generator 42 may include a light modulator 58 that modulates the color light received from the color source 50. The image generator can also directly emit color light encoded as an image, as if provided by an LCD-based display system. The modulator encodes the color light, typically on a pixel-by-pixel basis, to produce color-modulated light that is directed% along the optical path. The display device 48 directs the modulated light along the optical path for display. It may include focusing lenses and other optical devices provided on a screen or other display surface 60. Alternatively, the color images may be directed to focus and view on a display surface provided by a user. The light source, color generator, color source, light modulator, color image generator, or image display generator may each include a processor or controller suitable for controlling the operation of a device related to the 10 system, or a separate The controller 44, as shown, can be used. The controller can be configured to receive image information from the k-shirt image data source 62 and to receive an identification display condition from a condition identifier 64. The image data can be converted into commands suitable for driving different related components of the display system. 15 The condition identifier 64 can identify a display condition related to an image currently being displayed by the display system or at another time, including a condition provided by the user or affecting how the user perceives the image. In this article, the display: status can include image type, image content, image source, appearance of the displayed Fen image, user preferences, or ambient light conditions. The term 20 ambient light condition not only refers to the color collapse or brightness of the directly applied light, but also to any light source perceived by the user. Therefore, it also includes the perceived light emitted or reflected from space, and the visible matter of responders and daggers, which can also be called surroundings. Any factor, information, or condition that can be identified and related to the generated '% image' can be identified 1230009. For example, the condition recognizer 64 may include an image content analyzer 66, an ambient light M116 8 '-configured to receive a user, or other. [5 input 72 is a full-range selection device 70 and a display appearance analyzer 74 as provided by a keyboard, all of which are connected to the controller 44. It will be noticed that these features are for illustration, and this detail is not limited to the use of specific techniques for red, creating, or identifying one or more image display conditions.
The display system of this detailed description can take many different forms. For example, a display system 80 as shown in FIG. 3 may include 10 computers connected to one or more input devices 84, and image display hardware 86. The hardware 86 may correspond to hardware related to the image display generator 乂 or 仏. The computer may include a microprocessor 88, a memory 90 for storing data and computer programs for operating the system and processing the data, and individual input / output devices 92 and 94. As is well known, the computer and processor 15 may generally have any of a variety of structures or architectures. For example, a process can be used 'as shown in the figure. The processor may include functions related to the condition recognizer and the image display generator. Alternatively, it can be cut into separate processing modules, memory, and input / output devices related to related operational functions or hardware components. In addition, the methods and processes described in this document can be computer-driven, and the corresponding calculations can be programmed by processing in the form of ASK: = and so on. The algorithm can roughly be described as a set of related steps that lead to the establishment of the desired result. When stored, such algorithms can be stored in any computer-readable medium. Accordingly, these methods and processes are not inherently related to any particular computer or other device used to perform the associated operation. The processor may be a general purpose machine or a machine specially configured for a specified use. When separate machines are included, the separate machines can be connected directly or by a network like a local or wide area network. In the example shown in FIG. 3, many condition recognition functions are provided by the computer 82, like image content analysis performed on image information received from the image data source 96. The external device 84 may provide unprocessed, processed, or partially processed data. For example, a user input device 98, like a 10-key or switch, can be used to input the user's full range of choices. An ambient light sensor or sensor 100 may provide analog or digital information identifying the condition of the ambient light. A display sensor 102, like a charge-coupled element, can provide data on a displayed image. These devices may be attached to the casing of the computer or may be integrated into or on the image display hardware 86, as if they were display sensors suitable for receiving information from a displayed image. They can also be separated from it and connected by a suitable connection link as already discussed. Another embodiment, shown as a display system 110, is depicted in FIG. As seen in the drawings, the image data 112 may be connected to a system controller 114, which may take the form of a microprocessor, microcontroller, ASIC, etc., as already discussed. Various techniques exist for transmitting the image data 112. For example, the image data 112 may be transmitted through any one of an image port, a universal serial bus (USB), an infrared connection, a S-video port, or various types of connection links. One is passed to the controller 114. The image data 112 can be passed directly to the controller 114 'and can therefore be referred to as the original image data. The system 110 can be grouped to display images based on the image display status. In this article, display status refers to the status, factors, features, or characteristics of an image, and can include, for example, image type, image content, and shirt image source. , The appearance of the displayed image, user preferences, and / or ambient light conditions. The system 110 may therefore include an image analyzer 116, an ambient light sensor 118, and a full range selection device 12010 connected to the controller 114. No—the appearance analyzer 122 is displayed. It will be appreciated that these features are examples 4 &apos; and this detailed description is not limited to the use of these specific techniques to determine and / or establish a situation. For the system 110, the controller 114 is further connected to the light sources 124, 126, and 128. As shown in Figure 4, the number of light sources can be changed. For this purpose, the system 11 will be described as being configured with a red light source 10 0/1, a green light source 126, and a blue light source 128. As will be noticed, additional colors can be used, like white, cyan, yellow, and / or the reference 'red'. It will also be appreciated that any of these colored light sources may correspond to any of the light sources 124, 126, and 128, or an array of light sources 20, respectively. In this regard, the light sources 124, 126, and 128 may be optically connected to the optical elements 13, 132, and 134 and the beam couplers 136, 138, and 140 along respective portions 14ia, 141b, and 141c of the optical path 141. In this regard, the light rays 142, 144, and 146 from the light sources 124, 126, and 128 are directed to the stereo light modulator by the individual light 14 1230009 element 130, 132, and 134 via the beam combiners 136, 138, and 140. (SLM) 148. The SLM 148 is typically connected to the controller 114 and can cooperate in selectively directing light 15 through the optical element 152. The light 150 may include an image 154 to be displayed, whose system 5 corresponds to the image data 112. As shown in FIG. 4, an image 154 may be displayed on the screen 156. SLM 148 may be a digital micro-mirror device (DMD), LCD, LCOS, or any other mechanism capable of selectively directing light to display image 154. As will be noticed, the SLM 148 may be configured to direct light 41 to the lens 152 on a pixel-by-pixel basis to form a light 150 that may include an image 154. Therefore, as discussed further below, the controller 114 can arrange the light sources 124, 126, and 128 in order and can control the SLM 148. It can cooperate in the form described on the W surface to display the image 154 on a pixel-by-pixel basis. On screen 156. 15 As far as the system 110 is concerned, the image content analyzer 116 may be configured to receive image data. The image data may be inspected to express the image content in a formula. The image content analyzer 116 may then pass the image content information to the control 114. The image content information may, for example, include the number of unique colors included in the image data, the frequency of the unique color 20 rate, or the histogram, (c) the pixel intensity, like the average pixel of the image data Intensity, and (d) one or more of the changes in image data from one display frame to the next display frame. ", /, The video content can be determined in many ways. For example, the video content can be determined due to the source of the video content. In this regard, 15 1230009 video is input via a video image array (VGA) Port (not shown) to be transmitted to the display system 110, which can indicate that the image is an image image like a still photo or a graphic, and a high-brightness full range system can be selected. Alternatively, via a Super-video (S-video) port (not shown) Passing the image 5 to the display system 110 can indicate that the image is a dynamic image like broadcast television or video games, and a high-chroma full range system Can be selected. In another example, the video content itself can be checked to determine whether a motion or video image is to be displayed. If it will be perceived, the video content analyzer 116 may be implemented as, for example, included in a Software-readable instructions within the software program® 10 can also be implemented using pipeline processing. The ambient light sensor 118 can also be used with The controller 114 is connected. The sensor 118 may be configured to detect ambient light in an environment where a system 110 is being used to display an image. In this regard, the sensor 118 may be a charge-coupled 15-element (CCD), or any other sensor capable of detecting light, including a photovoltaic element. Information about the characteristics of ambient light, such as hue, saturation, brightness, color temperature, chroma, and power spectral density, can be From the sensor® sensor 118 to the controller 114. In response to this ambient light information, the controller 114 can change the order of the light sources 124, 126, and 128 and the operation of the SLM 148 to adjust the display of the image 154. These technologies are used in The following is discussed in more detail. The full-range selection device 120 may also be connected to the controller 114. In this regard, the full-range selection device 120 may be configured to display the full range of user selections. In this article, the full-range selection device 120 The range refers to the spectrum power distribution of the color 16 1230009 color range that the device can produce. The information transmitted from the control device H4 of the Lingwu Wudao Shiyou Wang Moqiang will cause this The controller changes the light when displaying the image 154 ^, the order of ⑶ and 128 and the result of the operation of the SLM148, such as adding or reducing one or more of the colored light generated during the display frame 5 or The amount of white light is the same. A higher setting on the full range selection device 12 will result in a lower setting or a brighter display compared to the display of image 154 based on the image data only ^ 2. The result of the image. Or, in addition, the 'full-range Xin device 12G can change the color temperature of the entire care, or some other attributes of the king range. It is used to change the overall information according to the information transmitted from the selection of I-Xin 10 I20 The scope of the technology is further discussed below; Other full-range changing techniques, such as those described with respect to other embodiments, including changes in the energy applied to the light source or the selection and use of a calender, can also be used. The display appearance analyzer 122 may also be connected to the controller 114. Display Appearance 15 The analyzer I22 can be configured to re-examine the display image 154. The appearance information can be expressed in formulas, like information related to the original image data. The appearance information must therefore be obtained by a CCD sensor or other suitable components. Information about the displayed image can be connected to # 制 哭 114 for use in improving the displayed image . 2〇 As previously explained, the controller 114 can arrange the light sources 124, 126, and 128 in order while displaying the image 154. For example, red, green, and color light sources can be turned on, or the light system can be allowed to pass through a light valve for a selected period every display pivot. Accordingly, timing pulses can be applied to such light sources. The red light source 124 can be turned on at the start of such a display frame] 7 1230009. The red light source 124 may remain on during the time period 4. The green light source 126 may then be turned on during time tG, and then the blue light source 128 is turned on during time tB. The time periods tR, tG, and tB may be approximately equal, non-overlapping time periods. Although this detailed description does not make such a limitation, 5 other timing relationships are possible. For example, if the image 154 has red content that is relatively low compared to its green and / or blue content, the red light source 124 will be turned on for a shorter time than the green light source 126 or the blue light source 128 during an agreed display frame. . Or, if the red light source has a lower brightness than other light sources, it will be turned on for a longer time. 10 It will be noticed that although 1/60 second frame width is used here as an example, for example, due to changes in image data, the display system can provide Variety. This typically results in a proportional change in the duration of different light sources. 15 The three light sources, one source, or three source RGB arrays can also be opened during a frame or an opening can be opened. twice. This sequence repeats during subsequent frames. Such a sequence can reduce the continuous color artifacts associated with the first example where the light source is turned on once during a frame. It will be noticed that continuous color artifacts can include multicolor shadows that can drag behind moving objects in a moving image, or due to flickering in which one color is brighter than the other. Other timing sequences are possible, such as the colors appearing three or more times per second or the colors appearing at different frequencies, like one red pulse and two green pulses. Moreover, the non-uniform pulse width can be used within a single frame of 18 1230009. Like a display frame, a light source is turned on three times, and one of the three time periods is about half of the other two. Specific timing relationships can be based on display conditions, such as full range selection, ambient lighting, image content, and display appearance, as discussed previously. The controller 114 can thus change the order of the light sources to achieve an appropriate RGB timing relationship based on the display conditions. In this regard, the time period during which a light source is turned on in a conventional display frame can be based on the display condition. For example, if an image to be displayed has a red content that is quite high compared to the green and blue content of the image, the red 10-color light source 124 can turn on a longer relative period during the display of the one image. time. In addition, as compared with the brightness provided with only those individual component colors, when higher brightness is desired, white light can be added. One such situation may include an environment in which ambient light does not increase the visibility of the image 154 without increasing the brightness. White light can be provided by a white light source. When only component colors are used, white light is provided by combining light of the component colors simultaneously. In the example shown, white rays can be generated during a time period tw, like the sum of red, green, and blue rays. This can increase the brightness of the image 154 when it is displayed. Yet another option is to add yellow light to an image. In this example, the red light source 124 and the green light source 126 can be turned on for a period of time tY at the same time, and 俾 can generate yellow light, the sum of red and green light. It will be noticed that, in this particular case, the green light 19 1230009 source 126 can be turned on (generating green light) separately during the frame, which is relatively shorter than the red light source 24 or the monitor color light source 128. Time period. Such a situation would be advantageous if a displayed image has high yellow content. In other words, the display system 11 changes the full range for displaying images one frame at a time, based on the display conditions, as described previously. Of course, the plutonium that will be noticed, the color sequence described in any of the foregoing examples will be repeated one or more times during a frame. 10 15 20 One by four, as shown in Figure 5®, and please cooperate with the first, a chart showing the relative timing between the device 120 and the controller 114, which is used to display the image. $ 5 Tiger-based model relative timing relationship diagram The 160 series is displayed on the chart 160, and the x axis represents the continuous range of the full range of selected values.

As can be seen from the graph m, the percentage of time that white light is generated during a given display frame relative to red, green, and blue light is at a critical value! Between the threshold and the threshold D2, the ambient light 21 1230009 changes in line intensity to change linearly. When the ambient light intensity is at a critical value τ2 or above the critical value T2, 'red, green, white, and blue light will each be generated a quarter (25%) of the conventional display frame, as shown in Figure 6 Indicated. Referring now to Figure 7, a graph 18o depicting an exemplary timing relationship based on average pixel intensity is displayed. In this regard, line 182 in FIG. 7 indicates a line 184 of the white light generated in a conventional display frame relative to the percentage of red, green, and blue light generated in that display frame. Percentage. At a lower average pixel intensity of 186 'below the critical value, no white light (0% of the display frame) will be produced, and red, green and blue light will each be One-third (33.33%). Mon 15 20
5 and 6 are the same. During this period, different types of light are produced. The relationship between the percentage of frame time (188 in Fig. 7) is compared by comparing lines 182 and 184 in i-table 180. produce. For example, from the chart, the time of the white / white light is generated during a conventional display frame. The percentage of green and blue light will secretly change between the threshold T1 and threshold 2 as the average pixel intensity changes. . When the average image ^ is at or above the critical value T2, red, green, and blue light rays are each generated to display a quarter of __ 5 as shown in Figure 7. As shown in Figures 5 and 6, they will be noticed. ”I 疋, the relationship depicted in Figure 7 is an example and the frame time 188 ′, other percentage relationships can exist. b Like shell material 112 #, can be processed to reduce the change in the display of related images j 22 1230009 through different display systems. In this regard, Fig. 8 is a graph 190 showing the gamma correction relationship. Such a relationship can be used to change the image data and can reduce the amount of change in the appearance of an image due to the type of display system. In this regard, the relationship shown in Table 51 is a series of curves of equation 192 'y: = χγ, which has a specific value of γ (gamma), which can be applied to a The red, green, and blue components of the color of the image. Alternatively, a correction system with individual values of gamma can be applied to individual components. In ancient terms, X can represent the rated redness of a particular pixel in an input image by 10 degrees. Then y can typically represent the rated gamma corrected red intensity of the projected pixel. 15 20 As can be seen in Figure 8, the line m corresponds to the case where the gamma is expected to be i. In this case, gamma correction will not be made. Also as shown in Fig. 8: It is shown that the group of the curve indicated by 196 corresponds to the relationship of correction coefficients whose gamma is smaller than i. Conversely, the group of the curve represented by 198 corresponds to the relationship of correction coefficients for gamma greater than m. According to this, the data can be entered into the ㈣weeΐ4, which means that the value of the gamma is relatively low, or the contraction of the entire range of the system is changed, such as due to changes in the optical path of the optical path or The correction coefficient to be applied is applied to the input image data according to the identified image display condition. Mother Wish Color can have
Different gamma curve, and the curve is not a smooth curve. In addition, the Θ ramp can change the sign again and again. FIG. 9 depicts a linear Yando Mo and Ba matrix relationship 200. Equation 202 is used to realize the linear relationship of the conversion between the first group of red, green 23 1230009 two colors of the original colors R Γ Ba Chi 0, G 0, and B 0. The correction coefficient can be calculated as a new red value. In this regard, the "new red" color correction coefficient c- is added to R. -C rl / positive coefficient CRG is applied to G. , And-red_blue correction coefficient 1B ° to be ^ ° Similarly, similar correction coefficients, as shown in square = 4, can be applied to determine the green and new
Equation 202 is in a linear matrix relationship of 204. With regard to this i, the original azimuthal color set 206 system can be multiplied with a positive k matrix of coefficients 2 () 8 which can include the equation, positive system #i: to generate a new, vector 210. It will be noticed that the image data system can be changed through various types, positive coefficients, color matrix, exponential relations, and lookup tables. For example, not all correction coefficients can be applied in several environments. The color matrix relationship used is based on the end view, at least, depending on the display status, 15 like the display appearance, the age of the image_display 111 system, and the type of image.
Lookup tables can save computing resources. Other factors are present, and the invention is not limited to these specific conditions. FIG. 10 depicts a display system 22 () using a color filter in the form of a single color wheel 222. As shown, the depicted display system 20 can further use a light source 224 configured to direct light 226 to the color wheel 222 along the optical path 228. Examples of the color wheel are described below in conjunction with Figs. Π and 21 to 23. In the depicted display system, light from the light source strikes a separate focusing mirror 230 and then hits a color wheel 222. Alternatively, without the focusing lens 230, a light source with an ellipse 24 1230009-shaped reflector can be used. The elliptical reflector has two focal points, one on the fireball and one on the integrating rod. However, it will be appreciated that the light source 224 may instead include a lens like the focusing lens 230. It will also be noticed that the light source 224 may be in the form of a high-pressure mercury lamp, but this detailed description 5 is not so limited. The color wheel 222 may be mounted on a shaft 232. The shaft 232 may be driven by a motor or some other driving mechanism capable of rapidly 'typically several thousand revolutions per minute (rpm), which rotates the color wheel. (Not shown) to operate. The color wheel 222 defines three color regions, a red region, a green · 10-color region, and a blue region. When the color wheel rotates, the three color regions pass through the optical path, and can continuously filter the light from the light source. Light. As shown, as it passes through the color wheel, the incident light 226 is filtered to produce colored light 234. Reflective filters can also be used, in which case light will be reflected away from these colored areas. With any of the embodiments, the optical path passes through the filter and the optical device. The colored light 234 may then pass through an integrating rod 236, which homogenizes the colored light 234 and directs the homogenized colored light to an illumination lens 238. Illumination lens · 238 can direct the homogenized colored light to a stereo light modulator (SLM) 240, like a digital micromirror device, an LCE), an LCOS, a 20 stereo light modulator, or a digital light processor Like. The use and operation of these SLM 240s is well known and will not be discussed in detail here. The stereo light modulator 240 converts the colored light from the color wheel 222 into a modulated colored light 242 containing images of different colors. The colored light will pass through a projection lens 244, and then along the optical axis 228 to a display table 25 1230009 on ice for image display. The viewer 2 also followed the optics. The boat: to watch the displayed image. The display system 220 ', as described in this regard, can produce a system with characteristics of the system, such as the received image information, the 5-spectrum color distribution of the light of the light source, and the different light fluxes in the color wheel. The characteristics of the filter, the lenses, the stereo light modulator, the screen, and any processing performed on the image are determined by the full range of displayed images. As it has been said, 'based on the image display information identified by the _image display status recognizer, a controller 252 can change the full range of 豸 _10 images in various ways, also known as color balance or Color characteristics, some of these methods will be explained. For the exemplary system shown in Figure 10, the controller 252 can change the full range by inserting, removing, or replacing one or more filters anywhere in the optical path 228. In particular, the system may include a support 254 for supporting a plurality of filters, such as filters 256 and 258. A carrier 26 under the control of the controller 252 selects and places the filters and optical devices in the optical path, as represented by the filter 258, and in the carrier 26〇φ ' Filter | represented by §256. However, one or more filters may be placed on the optical path, as indicated by a calender plus 20 shown in dashed lines. These filters may have different filtering characteristics to selectively alter the spectrum in different ways. The full range of an image is changed based on the combined effect of all filters moved to the optical path and away from the optical path. Then, you will realize that a variety of full range change systems-26 1230009 are obtained in different combinations corresponding to the various kinds of calenders in the optical path. This capability can be achieved regardless of where the calenders are placed in the optical path. For example, the calender may be-a portion 'of the light source structure as indicated by the dashed line 264. The calenders may be further arranged between the functional structures in the optical path, as depicted by the dashed lines 266, 268, and 270. A further filter position could also be between the screen 246 and the viewer 248, as indicated by the dashed line 272. In addition, any optical feature, like a lens or filter, or an optical wheel, can include an overcoat or element, although this would require the replacement of a plurality of such features in the optical path. In addition, a combination of interchangeable filters scattered along different optical stations along the optical path can also be provided. 15 20
The tunable filter can also be used in a display system with a branched optical path, like the system 11 depicted in FIG. 4. When Yidu Guangjie is placed on a component color source, like any of the color sources 124, 126, and 128 shown in the figure, the branch of the related optical path is OR. When the component is removed from the branch or part, the effect of the filter change is only related to the effect of the light incident on the stray light. The transmission characteristics of the individual light spoons were selected accordingly. Reflective filters can also be used. As shown in FIG. 10 again, the light source 224 combined with the lens 230 and the color wheel 222 includes a color source 274. A color source 274 is formed with the integrating rod 236, any of the adjustments' states, like the filter 258, the lens 238, and the stereo light modulator 24. A color source 274 is formed. The light source 224 and the corresponding color source 274 and the colored image source m can generate light having a brightness, intensity, or saturation corresponding to the level of the &amp; plus luminous energy. 27 1230009 The energy can be applied by a power source 278, which will respond to a control signal from the controller 252 representing a selected power level. An example of a pattern of energy applied to the light source 224 is depicted by a chart 280 in the u-th figure. This chart is a 5 chart for the applied energy versus time. For the sake of simplicity, the energy level is shown as a separate, single frame. When appropriate for a given application, this discussion can be applied to all frames or selected frames. A burst of pulses 282, 284, 286, and 288 have the same energy level, as represented by the fixed horizontal line. In this example, these pulses may have corresponding durations, as in duration book 10 290, and as shown are related to the generation of red, green, blue, and white rays during a frame. The duration of these pulses corresponds to the rotation angle of each filter. These filter angles may not be equal to 90 degrees each, but they add up to be equal to degrees. Supposing that the same level of energy is applied, the color source or color image source 15 276 can generate light with a relative level represented by the waveform tear in Figure 12, the waveform 292 is composed of individual pulses 294,296,298 and 3〇 () is formed. The highlighted result indicates that the effective saturation or brightness is I · lowest in terms of red and gradually increases' white has the highest brightness. By lightly applying the energy levels of light sources of different colors and the duration of each color, the compensation can provide a difference in the light source from a uniform color distribution. The level of energy that is applied during the generation of different colors can be further changed by the full range of desired generation. For example, 'If-a more uniform color distribution and a brighter full range are selected. Tongue's energy level sequence 3 shown in Figure 13 can be used by ⑨ · 28 1230009. The energy of the pulse 304 during the red period may be higher than the energy of the pulse 306 applied during the green period. The level of energy will be minimal during the generation of blue, as indicated by pulse 308. A white pulse 310 with a total duration Dw can be divided into 5-component durations D !, 02 and D3. The level L! Applied during the duration D! And D3 may be substantially the same, and the level L2 applied during the duration 02 may be suitably higher or lower. A rather narrow pulse with an elevated energy level, like the pulse 312 represented by level B2 during duration D2, is useful in extending the life of certain light sources. By applying such a pulse during the white duration Dw of a frame, it can be used to increase the brightness of a final image. The final color level produced by a color source or shaded image source can then be as shown by waveform 314 in FIG. Waveform 314 includes individual red, green, blue, and white pulses 316, 318, 320, and 322. The white pulse 15 pulse 322 includes a narrow pulse 324 resulting from the pulse 312. With such a result, the level of intensity can be increased from lowest to highest in the order of green, blue, red, and white. A composite image formed from colored images with these intensities will be viewed as having a fairly average color brightness and the image as a whole will be quite bright. As far as colors that are produced with substantially the same intensity are concerned, the naked eye can perceive that green light has the highest brightness and red light has the lowest brightness. In this case, by giving the green light the lowest intensity and the red light the highest intensity, these colors tend to appear to have similar brightness. The full range of an image can therefore be changed by changing the level of energy applied to a light source during the generation of different colors. The full range can also be changed by applying one or more positive or negative narrow pulses to one or more different colors. In addition, a full range of higher chroma can be produced by a reduction in time or energy level, or even by completely eliminating the 5 white light duration. Such a further example is depicted by waveform 330 in FIG. Fig. 15 depicts an example that may be similar to that shown in Fig. 13, except that a narrow pulse 332 series with energy may be applied to the light source during the holding period Dr that produces a red color. This produces a color 10 with increased brightness or saturation, as shown by the narrow pulse waveform 334 in FIG. 16. A color system that is produced with positive narrow pulses may accordingly appear to have increased saturation or brightness. As represented by a narrow pulse 338, shown in dotted lines, that occurs during the duration of the blue being generated by DB, a narrow pulse system may have a reduced energy level, resulting in reduced saturation or brightness of the color. In addition, the pulse 338 15 is shown to occur at the beginning of the duration DB. Such a pulse can occur at any time during the entire duration during which a color is to be generated. As already discussed, display systems can be considered with a fixed full range. In this regard, only a single range (full range) of colors can be produced by the 20th class system. Because the full range of high brightness will not be particularly suitable for displaying dynamic images, and the full range of high chroma will not be particularly suitable for displaying images. Consumers sometimes buy independent display systems to achieve the best of two types of images quality. However, such display systems can be expensive, making the purchase of multiple display systems undesirable. 30 1230009 Now shown in Figure 17 of Qingling Reading, a slightly schematic isometric view of a dynamic full-range display system according to an embodiment of the present invention is labeled 350. As shown in the figure, the system 350 includes an illumination or light source 352 configured to generate and direct light 354 to an optical branch 356 (indicated by a dotted line). The dynamic 5 full-range display system 350 may further include a condenser lens 358, an integrator rod 360, an illumination lens 362, a stereo light modulator 364, and a projection lens 366. The incident light 354 hits a continuous color filter or a color wheel 368 俾 including the color filter to generate a colored light 370. The individual different colors are directed along a common related portion 356a of the optical path 356. The colored light 370 may pass through the integrating rod 360, which homogenizes the colored light and directs the homogenized colored light toward the illumination lens 362. The illumination lens 362 can then direct the homogenized colored light to a stereo light modulator 364 that generates colored light 372 that is modulated to form a different color image directed along the 15-related optical path portion 356b. . The modulated colored light 372 may then pass through the projection lens 366 and then display an image 376 on a display surface 374. As shown, the display system 350 includes a first continuous color wheel 368, which may have a high chroma structure. The color wheel 368 may define a red filter 20 region 378, a green filter region 380, and a blue filter region 382. The depicted color wheel is typically used to produce moving images due to its high relative chroma (color intensity and saturation). In this regard, the color wheel 368 would be characterized to produce a "high chroma full range". The display system 350 also includes a second continuous color wheel 384, which may have a high brightness structure of 1230009, producing a sequence of colors similar to those depicted in Figures 11-16. The color wheel 384 can thus be seen to define a red area 386, a green area 388, a blue area 390, and a white area. The white area 392 may be a substantially barrier-free channel that provides white light through the dagger. The color wheel 384 can typically be used to generate an image image due to its white point relative to the cart π of the color wheel 368. As will be perceived, the chromaticity can be exchanged for the full range of brightness produced by the color wheel 384 relative to the color wheel 368. Therefore, the color wheel 384 will be characterized as producing a "high brightness full range". 10 15 20 Each of color wheel 368 and 384 towels can move to the optical path and leave the optical path. 俾 can be selected on the continuous filtering light 354 = Therefore, age H pure 35G can generate _ dynamic full The range is the full range of high chroma using the color wheel 368 for the static image or the full range of high brightness using the color wheel for displaying the image image. This full range can therefore be taken from the image frame. As such, the full range can be selected based on the physical environment (e.g., ambient light) and user preferences. 7 Ran color wheel 368 and second color wheel 384 are in the shape of a rotating wheel. ^ Other technologies that produce continuous colored light or make color filters continuously with :::: can be provided. For example, three color light sources are used: two, which have been matched with the system shown in Figure 4. Speaking of the scope of the display system such as t-call can therefore allow the display all &amp; &lt; according to the content of the currently displayed image to be changed. Brothers 18, 19, and 20 respectively depict three and 35 coffees in the 17th system. Features that will be the same as those in the system 32 1230009 350 will have the same reference numerals. These features include an illumination source 352, a condenser lens 358, continuous color wheels 368 and 384, a product knife ability 360, an illumination lens 362, a stereo light modulator 364, a projection lens 366, and an optical Rays of path 356. 5 Referring now particularly to FIG. 18, the display system 400 may include a carriage 402 on which the color wheels 368 and 384 may be rotatably mounted. The carriage 40 may be configured to selectively place a color wheel 368 or a color wheel 384 in the optical path he. The display system 400 therefore provides alternate positions of the two color wheels in the optical path. As will be seen, this can be done by moving the optical path, moving the color wheel, or both. If so, the display system of Fig. 18 can operate in two states related to the color wheel. In one state, the optical path passes through a color wheel, whereby the filters are included on the color wheel. In another state, the optical path passes through another color wheel, whereby the 15th grade filter system is included on the other color wheel. The carriage 402 may be controlled manually or automatically based on the image content or other identified display conditions as described previously. In addition, the color modification wheel 368 is placed in the optical path, and the light from the illumination source μ] is directed along the optical path. The same color wheel train is indicated by the dotted day line 20 because it can be placed when the carriage 402 is moved so that the color wheel 384 train is placed in the optical path. A variety of techniques exist for selectively aligning the color wheels 368 and 384 in the optical path. For example, a mechanical gate system may be used or, alternatively, a rotating mechanism, or some other transport mechanism system may be used. 33 1230009 Please refer to 'Display System 41〇' shown in Figure 19. The opposite of the display system right can be obtained by using continuous color wheels. These color wheels Mg,% 4 can be rotatably installed in relation to the lighting source 352 Predetermined location. Accordingly, the display system 410 may use an optical path director 412 that selectively changes the optical path of the light 354 from the illumination source 352. This optical path director may include mirrors 413, 414, 415, and 416. These mirrors 413, 414, 415, and 416 may move to or leave the optical path by themselves, as indicated by the mirrors 415 and 416 shown in dashed lines. Light to one of these color wheels. Alternatively, a prism or other optical element system may be used. With respect to the indicator system 410 and 5, the incident light 3 5 4 from the light source 3 5 2 can be transported through the condenser lens 358. The mirror 415 can then change the path 356 of the light 354, directing it to the color wheel 384 instead of passing through the color wheel 368. The mirror 413 may then direct the light 354 through the color wheels 384 产生 15 to produce a colored light 370. The shaded light 370 can then be directed by the mirror 414 to the mirror 416, which can then direct the shaded light to the integrating rod 36o. As the moving mirrors 415 and 416 leave the optical path, the light system can be directed through the color wheel 368. The optical path of the light from the light source 352 can therefore be selectively changed depending on the content of the image (e.g., image or moving image) to be displayed, as previously discussed. FIG. 20 is a schematic diagram of a dynamic full-range display system 420 according to yet another embodiment of the present invention. The color wheels 426 and 428 may take the form of a color wheel installed within the silk screen display system so that the directed light passes the temple color wheel in succession. The two color wheels can be controlled independently. 34 4 1230009 Typically, the first of the color wheels can be rotated while the other color wheel train is maintained in a fixed position. In this embodiment, the color filters are color wheels, and the color wheel trains are coaxially mounted on a shaft 422. Alternatively, the color wheels may be configured such that the color wheel trains 5 rotate together with each other at a fixed angular position. Further, the color wheel 426 may be fixed in the optical path 356 and the color wheel 428 may be selectively removed from the optical path, as depicted by the color wheel 428 represented by a dotted line. Various structures of the color area can be used on the color wheels 426 and 428. For example, a color wheel may define four color regions of approximately the same size · 10 inches, such as a red region, a green region, a blue region, and a white region as depicted by the color wheel 384 in the second figure. The white area may be made smaller than the other areas, or the areas may have different sizes. One color wheel can remain stationary while the other is turning. That is, the incident light can thus pass through the white area of one color wheel, and continuously pass through the color area of the other color wheel as the other color wheel rotates. = If the two color wheels have white areas of different sizes, then by rotating the color wheel system with smaller white areas, it can be used to produce a full range of chromaticity. The opposite case, in which the color wheel train with a larger white area is turned, can then produce a full range of higher brightness compared to 20. Color wheels such as xuan can include markings along their perimeter, like-on the surface or k, 俾 can provide accurate positioning of these color wheels. Any other 'self or rotational position sensing structure can be provided to allow operation of the color wheel as described. 35 1230009 δ Month Special Figures 21 to 23, the optional structure of the color wheel is depicted as color wheels 426 and 428. As shown in Figure 21, Color_426 and 428 are similar and typically include six color regions of approximately the same size. A color wheel therefore includes a red region 43, a green region 2, 5 a blue region 434, and three white regions 436. As shown in Figure 21, the white areas of the color wheels 426 and 428 can be aligned with the marks 442 corners using sensors 438 and 440, respectively. Once the combined angular relationship is achieved, the color wheels can be fixed relative to each other and then turned together to collectively define a continuous color filter. In this structure 10, a relatively high brightness full range can be generated, even when compared with the high brightness full range generated by the color wheel 384 as depicted in FIG. A higher brightness (white point) can be achieved by the structure depicted in Figure 21 because about half of the surface area of the aligned color wheels 426 and 428 is white, such as four times the surface area of the color wheel 384 One for comparison. In this way, the 15 series can compensate for the reduced brightness of these colors because the light must pass through two color filter sections. In the figure 22, the white area 436 of the color wheel 428 is aligned with the red area 430, the green area 432, and the blue area 434 of the color wheel 426, respectively. The opposite is also possible. Again, the sensors 438 and 44 may determine the angular positions of the color wheels 20 426 and 428, respectively. The color wheels may then be fixed at an angle relative to each other and rotate together. In this structure, the color wheel trains collectively define a continuous color filter that is configured to produce a full range of high chroma. Such a full range can be compared with the full range of high chroma produced by the color wheel 368. When no white or color area is maintained in red, green or blue color that does not correspond to the color wheel on the other color wheel 36 1230009 When the area is aligned. The resulting color sequence is red'green_blue. These color wheels can also be aligned so that the same color is not produced continuously by the two color wheels. For example, if the color wheel 428, as seen, is rotated counterclockwise by 120 degrees, the colored light will have the order blue_green-red-monitor-green-red. This sequence will have reduced continuous color artifacts due to the increased frequency of different colors. Figure 23 depicts the color wheels 426 and 428 aligned in the middle of the arrangement depicted in Figures 21 and 22. In this regard, the white 10 area 436 of one color wheel is positioned so that it can only partially re-register with the white area of the other color wheel. It will be appreciated that the amount of overlap can be changed, which will allow a large number of full ranges with a wide range of chrominance and brightness characteristics to be generated. As previously discussed, sensors 438 and 44 may be used to establish a desirable angle between these color wheels that are used to generate a desired full range of colors. 15 Such a structure may allow for chromaticity or brightness. This is based on subtle changes in the valley of the image, ambient light, or various other factors. Now please see Figure 24. A flowchart 45O depicting a method for displaying an image is shown. As shown in Fig.%, The method may include receiving image information in step 452. -Display noise, like 20 valleys in the image, display appearance, full range selection or ambient light conditions, can be identified in step 454. A plurality of different color images based on the identified display condition can then be generated in steps 4 5 6. The different color images may be directed along an optical path in step 458. The different color images: ,,,, and later can be displayed at step 46. Such a method can use any of the methods described in the previous 37 1230009 *%, however, the method is not limited to these methods because other technologies are possible.
