6> -物鏡，使其射出光 瞳（P u p i 1)基本上是與該攝影物鏡的射入光瞳相疊合。 在上述裝置的另一佈置中，在投影光路徑中在該偏向 裝置和該攝影物鏡之間配置一物鏡，其用來進行正的成像 修正。於是’基本上該偏向裝置的非線性可被補償，此非 線性例如可以是該偏向裝置中所包含的偏向鏡之振動過程 中角速率的變化。該物鏡是一種具有至少一透鏡的透鏡系 統，其可製備一種補償該非線性用的成像。 另一種佈置的設計方式是以一種平面式的照明和成像 用的元件來進行投影。 在一種實施形式中，該成像用的元件是一種在傳輸或 反射時用的液晶顯示器。在另一實施形式中，該成像用的 元件是一種各別可調整的微鏡面所形成的配置，其亦可包 含多個（例如，三個）液晶和微鏡面。 依據上述裝置的一實施形式’該成像用的元件之平面 照明用的照明裝置具有由發光二極體和雷射所構成的組之 至少一兀件。特別是亦可使用至少一發光二極體和至少一 雷射來進行照明。 200914984 上述裝置的其它佈置的設計方式亦可爲：使該成像用 的元件之照明系統的射出光瞳是與該攝影物鏡之射入光瞳 相疊合。 在上述全部的實施形式中，已投影的圖像之聚焦是藉 由該攝影物鏡之相對應的功能來進行。 本發明的上述裝置之其它優點和較佳的實施形式描述 在以下之與圖式有關的各實施例中。 【實施方式】 在各實施例和圖式中，相同或作用相同的組件分別設 有相同的參考符號。所示的各組件以及各組件之間的大小 比例未依比例繪出。反之，爲了清楚之故，圖式的一些細 節已予以放大。 第1A，1B圖所示的裝置是一種攝錄像機，藉此可攝取 移動的圖像和音調。在攝取一圖像22時，待進行攝影的光 束2經由一攝影光路徑2 1且因此通過一攝影物鏡3。 如第1 B圖所示，裝置1另外具有一種圖像投影功能。 於是，可藉由此一裝置1將一圖像42投影至一配置在該裝 置外部的投影面上。一種待進行投影的光束4因此經由一 投影光路徑4 1且通過該攝影物鏡3。 爲了接收音調，該裝置1例如須具有一種麥克風33。 在投影期間爲了使音調（例如，已記錄的音調）再生， 則該裝置1例如須具有一擴音器。 第2圖所示的裝置1具有一種依據飛點-原理所形成的 圖像投影功能。於此裝置1中包括一光源8和一偏向裝置 200914984 該掃描用的光源8例如具有至少一雷射8 1，其發出綠 光；至少一雷射8 2，其發出紅光；以及至少一雷射8 3，其 發出藍光。由雷射8 1，8 2，8 3在操作時所發出的光束例如 藉由多個轉向元件11而相組合且偏向至一偏向單元7。各 轉向元件1 1例如具有簡易製成的鏡面1 1 1和可選擇波長的 反射鏡1 1 2。 基本上亦可與以上所示的實施例不同，使該光源8所 具有的不同彩色的數目不同或使該光源8具有不同數目的 雷射。例如，可只包含唯一的雷射，其發出唯一的彩色的 光。作爲另一例子，該光源可包含二個雷射，其分別發出 不同彩色的光。此外，該掃描用的光源8亦可發出四種不 同的彩色，該光源8因此例如可包括四個不同的雷射。 綠雷射81顯示成較其餘的雷射82，83還大，其原因 在於，在目前技術中綠色的雷射光通常不是直接由半導體 雷射所產生而是由非線性的光學過程所產生，這需要較大 的空間需求。適當的雷射已爲此行的專家所熟知，且特別 是亦可在商場上買到。 該偏向裝置7(亦稱爲光學掃描器）例如可具有一·種在 二個方向中振動的微鏡面或一部份或全部由一種微鏡面所 構成。可在二個方向中振動的微鏡面將一光束相對於一即 將投影的平面圖像而在二維中偏向。另一方式是，該偏向 裝置7具有至少二個分別是一維的偏向鏡，其將光束相對 於一即將投影的平面圖像而分別在一維中偏向。另一方式 -10- 200914984 是，該偏向裝置7亦可具有一種旋轉鏡，例如’多邊形的 旋轉鏡。此種光學偏向裝置7已爲此行的專家所知悉，且 至少一部份亦可在商場上買到。 圖像投影是藉由各別的圖像點之依序的投影來達成。 於此，待投影的光束可藉由該偏向裝置7以經由投影面而 受到引導。該圖像例如以列的方式而組成，這類似於傳統 式電視攝像管之一般作用方式。或者，光點在投影面上的 移動可表不一種麗莎傑士（Lissajous)圖。 '待投影的光束全部經由一投影光路徑4 1，此路徑4 1 經由該攝影物鏡3。由待進行攝影的光束2所經過的一攝 影光路徑2 1同樣經由該攝影物鏡3。 該裝置1具有一種開關元件5，藉此可選擇性地對該 投影光路徑41或攝影光路徑21進行調整。第2圖顯示一 種狀態，其中該投影光路徑41已被調整。於該投影光路徑 4 1中包含一鏡面5 1。此鏡面5 1例如在空間中是配置在一 圖像感測器6和g亥攝影物鏡3之間。一般而言，該鏡面5 1 " 配置在該攝影光路徑2 1中。當調整該投影光路徑4丨時， 須配置該鏡面5 1 ’使該攝影光路徑2 1被該鏡面5丨所阻斷。 該鏡面51可由該攝影光路徑21移動出來。這例如是 藉由旋轉來達成，此處例如使用一種傾斜鏡面。另一方式 是’該鏡面51亦可藉由一種平移來移動。此外，該鏡面亦 可藉由至少一平移和至少一旋轉之組合而移動或藉由多個 平移或多個旋轉而移動。 由第2圖所示的狀態開始，藉由該鏡面5丨之移動來調 -1 1 - 200914984 整該攝影光路徑2 1。須配置該鏡面5 1，使待投影的光束不 再偏向至、不再完全偏向至或不再以最佳方式偏向至一通 向該攝影物鏡3之投影光路徑4 1中。藉由該開關元件5， 則可在本實施例中調整該攝影光路徑2 1和該投影光路徑 51。該開關元件例如藉由一種可由外部來操控的開關來操 作，藉此開關可導入該投影功能。 第3 ’ 4和7圖所示的裝置1同樣具有一圖像投影功能， 其包括一種藉由一光源8和一光學偏向裝置7來達成的飛 ^ 點-投影。 此外’依據上述各實施例的裝置都具有一種開關元件 5，其類似於第2圖所示的實施例而可具有一鏡面5丨，該鏡 面5 1可移動以調整一投影光路徑或一攝影光路徑。 第3圖所示的裝置1包含多個光學元件1〇，其將該光 源8之至少一光束聚焦於I亥攝影物鏡3之圖像平面2 0中。 光學元件10因此是一聚焦裝置的組成元件。該攝影物鏡之 圖像平面在該投影光路徑41中位於一與該攝影光路徑21 ^ 中的位置不同的位置上。在該攝影光路徑2 1上，該圖像平 面大約位於圖像感測器6之外面上。 該聚焦裝置1 0例如具有三個球形或非球形的透鏡，其 例如分別配置在一綠色' 一紅色和一藍色雷射8丨，8 2，8 3 之雷射束之光束路徑中。這些透鏡將各別的雷射束聚焦在 該攝影物鏡3之圖像平面20中。 然而，在使用多個雷射束時，亦可首先藉由轉向元件 11而將雷射束偏向至一共同的投影光路徑41上且然後藉 -12- 200914984 由唯一的聚焦裝置而將雷射束聚焦在該圖像平面2〇上。該 聚焦裝置例如可具有唯一的聚焦單元或亦可具有多個聚焦 單元。該唯一的聚焦裝置例如配置在轉向裝置11和偏向裝 置7之間的投影光路徑4 1中。 在上述裝置之第4和7圖所示的實施例中，在投影光 路徑4 1中在掃描器7和攝錄像機3之間配置另一物鏡9。 此一物鏡9例如可以是f- 0 -物鏡，其亦稱爲掃描-物鏡。 另一方式是，該成像亦可藉由物鏡9而作正的修正。 f 投影系統使用一光源和一偏向裝置來產生圖像，在此種投 影系統中’由光源所產生的投影光束大部份都以很高的速 率在投影面上移動，以產生圖像。於是，例如可使用一種 很快速旋轉的多邊形鏡面以用於垂直偏向中，且使用一種 振動鏡面以用於水平偏向中。然而，亦可使用一種在二軸 中振動的（微-)鏡面，此時不需使用二個鏡面。爲了藉由此 一鏡面來形成圖像，則此一鏡面須設置成諧和的（harmonic) 共振，其可使該投影光束相對應地偏向。 I_ 由於振動式移動’則螢幕上的光點在偏向區域上的速 率不固定。這樣會使該圖像的邊緣區域中（即，在振動式移 動之轉折點上）光點的移動速率較慢，這樣會在該光源之光 功率固定時造成一種較高的亮度。爲了產生一種亮度均勻 的圖像，需包含物鏡以補償該偏向裝置之至少一種非線性。 該非線性可藉由一種光偏向裝置之移動（特別是在至 少一偏向鏡面振動時）而形成。例如，該移動可與一投影面 上一光點速率之變動有關。該物鏡9例如是一種透鏡系 200914984 統，其具有至少一透鏡，該透鏡提供了一種可補償上述非 線性用之修正。 藉由該偏向裝置和該投影面之間設置該物鏡9，則該 透鏡系統之上述修正功能可完全消除或部份消除一光點之 速率振動。此種修正因此可使投影在螢幕上的光點之速率 之大小成爲固定或至少使速率的變動小於先前技術中者。 於是，基本上可產生時間上等距離的像素，使得在鏡面速 率可變動且光功率固定時由該光源所產生的像素具有相同 的亮度。 該透鏡系統可由一唯一的透鏡所構成，但亦可有利地 由多個透鏡所構成。有利的方式是亦可使用圓柱形透鏡。 使用f- 6> -物鏡於一種雷射投影系統，這已描述在US 5 694 1 80 A中，其以無修正的方式設計而成。 在第4圖所示的實施例中，該物鏡9是一種f- β -物 鏡，其使待投影的光束在二側（即，在光束輸出側）上基本 上以遠心方式來成像。光束因此基本上平行於該投影光路 徑4 1之光主軸而傳送。 另一方式是，該物鏡9使該待投影的光束成像，以便 除了在中間圖像平面20上的聚焦之外亦使該物鏡的射出 光瞳可與該攝影物鏡之射入光瞳相疊合。這已顯示在第7 圖中。光束於此處並未全部平行於一光學主軸而傳送而是 具有收斂性或發散性，使該攝影物鏡之射入光瞳可被照明。 f- 0 -物鏡或作爲f- 0 -物鏡用的掃描-物鏡已爲此行的 專家所知悉，其特別是可在商場上買到。 -14- 200914984 上述裝置之第5和6圖所示的實施例顯示一投影裝置 之圖像投影功能，其包括一成像用的元件1 3之平面式照 明。 平面式照明用的照明裝置12例如具有至少一光源 1 21 ’其發出綠光；至少一光源12 2，其發出紅光；以及至 少一光源1 2 3，其發出藍光。光源1 2 1，1 2 2，1 2 3例如分別 是雷射或電致發光二極體組件或電致發光二極體晶片。然 而’電致發光二極體和雷射二極體亦可一起用作光源121， 1 22 ’ 1 23。平面式照明另外亦可發出多於三個或小於三個 的不同的彩色。此外，平面式照明中所包含的光源1 2 1， 122，123之總數可改變。 由光源所發出的光束可藉由轉向元件11而轉向至該 成像用的元件1 3和該投影光路徑4 1上。光束例如通過一 整合器1 4和一中繼透鏡1 5。 該整合器是一種光學裝置，藉此可使一照明裝置12所 發出的光儘可能均勻地混合。例如，該整合器可以是一種 光混合棒或蜂房式電容器。這些光學元件已爲此行的專家 所知悉。 電驛15例如是一種光學裝置或光學元件，其基本上可 使該整合器14之光發出面成像在該圖像形成用的元件13 上。該元件1 3例如具有一成像透鏡或由一成像透鏡所構 成。電驛1 5特別是亦可由多個部份所組成，例如，其可具 有多個透鏡’各透鏡一起用來成像。成像裝置或成像透鏡 可適用於電驛，這基本上已爲此行的專家所知悉。 -1 5 -

Field of the Invention The present invention relates to a device having a photographing function, by which a light beam to be photographed is passed through a photographic objective lens. [Prior Art] Classical devices having a photographing function, such as a light camera and a camcorder, are known. In addition, a variety of mobile phones have a photographic function during this period. Further, other studies on mobile phones having integrated projection devices are also known. The corresponding products have not been developed. Often, more devices have been bursts that can integrate multiple different functions simultaneously. SUMMARY OF THE INVENTION It is an object of the present invention to provide a device having a photographic function in which another advantageous function is integrated. Currently, there is a device having a photographing function which additionally has an image projection function. The image projection function may additionally exist or may additionally exist in addition to the display. For example, an image projection function can be used in the apparatus to: project the captured image or the movable image onto the surface of the exterior of the apparatus by the photographing function. According to an advantageous embodiment, a beam to be projected is passed through the photographic objective of the device when the image projection function is used. In this embodiment, the photographic objective lens thus serves as an objective lens for photography, and also serves as an objective lens for projections of Fig. 200914984. Thus, the image projection function can be particularly space-saving and cost-effectively integrated in a device having a photographic function. According to another embodiment, a digital image sensor for photographic functions is included in the above apparatus. According to one arrangement, the device has an optical camera, video camera or mobile phone. These names are related to one of the main functions of the device. These names do not exclude other features. For example, the camera function of the mobile phone can additionally have a light photography function as well as a camcorder function. In the sense of the present invention, the light photographing function and the camcorder function are an arrangement of photographing functions. According to a further embodiment, a mechanical switching element or an electromechanical switching element is included in the device. With such a switching element, a photographic light path and a projection light path can be adjusted. In particular, these light paths can be selectively adjusted so that the photographic light path or the projected light path can be adjusted. However, substantially the other optical path can be adjusted in addition to one of the optical paths. The photographic light path extends between the image sensor and the photographic objective. The projected light path extends between a projection source and the photographic objective. According to a possible embodiment, the switching element substantially removes the image sensor from the image plane of the photographic objective, and instead forms an intermediate image plane or an image for the projection system. The components are located there. According to a further embodiment, the image plane of the photographic objective is positioned in the intermediate image plane of the projection system or on the component for image formation by introducing a mirror. In one arrangement of the above apparatus, the image sensor is placed in a movable 200914984 manner. In order to adjust the photographic light path or the projected light path, the switching element has to move the image sensor. That is, the image sensor is moved by the switching element during the switching process. Furthermore, in another arrangement of the device a movable mirror is included. The mirror surface is moved by the switching element during switching in the adjustment of the photographic light path or the projection light path. The image sensor and the mirror are substantially movably movable. The movements made during a switching process may include at least one translation, at least one rotation, or a combination of at least one translation and at least one rotation. Another embodiment of the above described device is designed in such a way that image projection is achieved when a light source and an optical deflecting device are used. In one arrangement, the projection is thus performed by a spot that moves on the projection surface - and thus the brightness has been modulated. Part of this projection principle is also called "F1 y i n g S ρ 〇 t) projection. This projection principle is similar in function to the image generation principle in a television camera tube. The image points of the image are sequentially generated and thus combined into one image. Here, the device can include a light source and a biasing unit (e.g., one or more scanning mirrors). The deflection unit directs the light beam of the light source on the projection surface. In this way, the image to be projected is sequentially generated on the projection surface. In one arrangement, the light source has at least one laser. In addition, another light generating component may be included, for example, may include at least one electroluminescent diode. According to a further embodiment, an f-6>-objective lens is arranged in the projection light path between the deflection unit and the photographic objective 200914984, which focuses the beam to be projected on a plane. In an f-β-objective lens, there is a ratio as precisely as possible between the angle of incidence of the beam and the position of the image point that has been focused in the image field plane. According to one arrangement, the imaging achieved by the f-beta-objective lens is substantially telecelic imaging on the image side. According to another arrangement, the f-6>-objective lens must be formed such that its exit pupil (P u p i 1) is substantially superimposed on the entrance pupil of the photographic objective. In another arrangement of the above apparatus, an objective lens is disposed between the deflecting means and the photographic objective in the projection light path for positive imaging correction. Thus, the nonlinearity of the deflection device can be compensated for, which may be, for example, a change in the angular velocity during the vibration of the deflection mirror contained in the deflection device. The objective lens is a lens system having at least one lens that produces an image for compensating for the nonlinearity. Another arrangement is designed to project with a planar illumination and imaging component. In one embodiment, the imaging element is a liquid crystal display for use in transmission or reflection. In another embodiment, the imaging component is a configuration formed by a respective adjustable micromirror, which may also comprise a plurality (e.g., three) of liquid crystals and micromirrors. According to an embodiment of the above apparatus, the illumination device for planar illumination of the component for imaging has at least one member of the group consisting of a light-emitting diode and a laser. In particular, it is also possible to use at least one light-emitting diode and at least one laser for illumination. 200914984 Other arrangements of the above apparatus may be designed such that the exit pupil of the illumination system of the imaging component overlaps the entrance pupil of the photographic objective. In all of the above embodiments, the focus of the projected image is performed by the corresponding function of the photographic objective. Further advantages and preferred embodiments of the above described apparatus of the present invention are described in the following embodiments relating to the drawings. [Embodiment] In the respective embodiments and drawings, the same or identical components are respectively provided with the same reference symbols. The components shown and the size ratios between the components are not drawn to scale. Conversely, some details of the drawings have been exaggerated for clarity. The apparatus shown in Figs. 1A, 1B is a video camera whereby mobile images and tones can be taken. When an image 22 is taken, the beam 2 to be photographed passes through a photographic light path 21 and thus passes through a photographic objective 3. As shown in Fig. 1B, the device 1 additionally has an image projection function. Thus, an image 42 can be projected by a device 1 onto a projection surface disposed outside the device. A light beam 4 to be projected is thus passed through a projection light path 41 and through the photographic objective lens 3. In order to receive the tone, the device 1 must, for example, have a microphone 33. In order to reproduce the tones (e.g., recorded tones) during projection, the device 1 must, for example, have a loudspeaker. The device 1 shown in Fig. 2 has an image projection function formed in accordance with the flying spot principle. The device 1 includes a light source 8 and a deflecting device 200914984. The scanning light source 8 has, for example, at least one laser 81 emitting green light; at least one laser 8 2 emitting red light; and at least one lightning Shoot 8 3, which emits blue light. The light beams emitted by the lasers 8, 1, 2, 8 3 during operation are combined, for example by a plurality of deflection elements 11, and are biased towards a deflection unit 7. Each of the steering elements 1 1 has, for example, a mirror 11 1 which is simply formed and a mirror 1 1 2 of a selectable wavelength. Basically, it may be different from the embodiment shown above, such that the light source 8 has a different number of different colors or that the light source 8 has a different number of lasers. For example, it may contain only a single laser that emits a single colored light. As another example, the light source can include two lasers that respectively emit light of different colors. Furthermore, the source 8 for scanning can also emit four different colours, which light source 8 can thus for example comprise four different lasers. The green laser 81 is shown to be larger than the remaining lasers 82, 83 because the green laser light in the prior art is usually not directly generated by a semiconductor laser but by a nonlinear optical process. Need a larger space requirement. Proper lasers are well known to experts in the field and can be purchased especially at the mall. The deflecting means 7 (also referred to as an optical scanner) may, for example, have a micromirror that vibrates in two directions or a part or all of which consists of a micromirror. A micromirror that can vibrate in two directions deflects a beam in two dimensions relative to a projected planar image. Alternatively, the deflecting means 7 has at least two one-dimensional deflecting mirrors which respectively deflect the light beam in one dimension with respect to a planar image to be projected. Another way -10-200914984 is that the deflecting device 7 can also have a rotating mirror, such as a 'polygonal rotating mirror. Such optical deflecting devices 7 are known to experts in the field and at least some of them are also commercially available. Image projection is achieved by sequential projection of individual image points. Here, the light beam to be projected can be guided by the deflection device 7 via the projection surface. The image is composed, for example, in a column manner, which is similar to the general mode of operation of a conventional television camera. Or, the movement of the spot on the projection surface may not represent a Lissajous figure. The light beam to be projected is all passed through a projection light path 4 1, via which the path 4 1 passes. A photographic light path 2 1 through which the light beam 2 to be photographed passes passes through the photographic objective lens 3 as well. The device 1 has a switching element 5 whereby the projection light path 41 or the photographic light path 21 can be selectively adjusted. Figure 2 shows a state in which the projected light path 41 has been adjusted. A mirror surface 51 is included in the projection light path 41. This mirror surface 51 is disposed, for example, in space between an image sensor 6 and a g-photography objective lens 3. In general, the mirror 5 1 " is disposed in the photographic light path 2 1 . When the projection light path 4丨 is adjusted, the mirror surface 5 1 ' must be arranged such that the photographic light path 2 1 is blocked by the mirror surface 5 。. The mirror surface 51 can be moved by the photographic light path 21. This is achieved, for example, by rotation, here for example a tilted mirror. Alternatively, the mirror 51 can also be moved by a translation. Moreover, the mirror surface can also be moved by a combination of at least one translation and at least one rotation or by a plurality of translations or multiple rotations. Starting from the state shown in Fig. 2, the photographic light path 2 1 is adjusted by -1 1 - 200914984 by the movement of the mirror surface 5 。. The mirror surface 51 is to be arranged such that the beam to be projected is no longer deflected, is no longer fully deflected or is no longer optimally deflected into a projection light path 41 into the photographic objective 3. With the switching element 5, the photographic light path 21 and the projection light path 51 can be adjusted in this embodiment. The switching element is operated, for example, by a switch that can be manipulated externally, whereby the switch can be introduced into the projection function. The apparatus 1 shown in Figs. 3' and 7 also has an image projection function including a flying point-projection achieved by a light source 8 and an optical deflecting means 7. Furthermore, the device according to the above embodiments has a switching element 5 which, like the embodiment shown in Fig. 2, can have a mirror surface 5 可 which can be moved to adjust a projection light path or a photographic image. Light path. The device 1 shown in Fig. 3 comprises a plurality of optical elements 1 〇 which focus at least one of the light sources 8 in the image plane 20 of the I photographic objective lens 3. The optical element 10 is thus a constituent element of a focusing device. The image plane of the photographic objective is located in the projection light path 41 at a position different from the position in the photographic light path 21^. On the photographic light path 21, the image plane is located approximately on the outer surface of the image sensor 6. The focusing device 10 has, for example, three spherical or non-spherical lenses which are respectively arranged, for example, in the beam path of a laser beam of green 'one red' and one blue laser 8', 8 2, 8 3 . These lenses focus the respective laser beams in the image plane 20 of the photographic objective 3. However, when multiple laser beams are used, the laser beam may first be deflected by a steering element 11 onto a common projection light path 41 and then by a unique focusing device by -12-200914984 The beam is focused on the image plane 2〇. The focusing device can, for example, have a single focusing unit or can also have a plurality of focusing units. This unique focusing means is for example arranged in the projection light path 41 between the steering device 11 and the deflection means 7. In the embodiment shown in Figs. 4 and 7 of the above apparatus, another objective lens 9 is disposed between the scanner 7 and the camcorder 3 in the projection light path 41. This objective lens 9 can be, for example, an f- 0 - objective lens, which is also referred to as a scanning-objective lens. Alternatively, the imaging can be corrected positively by the objective lens 9. f The projection system uses a light source and a biasing device to produce an image in which most of the projected beam produced by the light source moves at a very high rate on the projection surface to produce an image. Thus, for example, a very fast rotating polygonal mirror can be used for vertical deflection and a vibrating mirror can be used for horizontal deflection. However, it is also possible to use a (micro-) mirror that vibrates in two axes, in which case two mirrors are not required. In order to form an image by means of such a mirror, the mirror surface must be arranged in a harmonic resonance which allows the projection beam to be correspondingly deflected. I_ Due to vibrating movement, the speed of the spot on the screen is not fixed on the deflecting area. This causes the movement of the spot in the edge region of the image (i.e., at the turning point of the vibrating motion) to be slower, which results in a higher brightness when the optical power of the source is fixed. In order to produce an image of uniform brightness, an objective lens is included to compensate for at least one of the nonlinearities of the deflection device. This non-linearity can be formed by the movement of a light deflecting device (especially at least when the mirror is vibrated). For example, the movement can be related to a change in the spot rate on a projection surface. The objective lens 9 is, for example, a lens system 200914984 having at least one lens which provides a correction for compensating the aforementioned non-linearity. By providing the objective lens 9 between the deflecting means and the projection surface, the above-described correcting function of the lens system can completely eliminate or partially eliminate the rate vibration of a spot. Such a correction thus allows the rate of the spot projected on the screen to be fixed or at least such that the rate variation is less than in the prior art. Thus, pixels that are equidistant in time are substantially generated such that pixels produced by the source have the same brightness when the mirror rate is variable and the optical power is fixed. The lens system can be constructed from a single lens, but can advantageously be constructed from a plurality of lenses. Advantageously, a cylindrical lens can also be used. An f- 6>-objective lens is used in a laser projection system, which has been described in US 5 694 1 80 A, which is designed in an uncorrected manner. In the embodiment shown in Fig. 4, the objective lens 9 is an f-β-object lens which causes the light beam to be projected to be imaged substantially telecentrically on both sides (i.e., on the beam output side). The beam is thus transmitted substantially parallel to the optical principal axis of the projected optical path 41. Alternatively, the objective lens 9 images the light beam to be projected so that the exit pupil of the objective lens can overlap with the entrance pupil of the photographic objective lens in addition to the focus on the intermediate image plane 20. . This is shown in Figure 7. The beams are not all transmitted here parallel to an optical spindle but have a convergence or divergence so that the entrance pupil of the photographic objective can be illuminated. The f- 0 - objective lens or scanning-object lens for the f- 0 - objective lens has been known to experts in this field, and it is especially available at the mall. The embodiment shown in Figures 5 and 6 of the above apparatus shows an image projection function of a projection apparatus comprising a planar illumination of an imaging element 13. The illumination device 12 for planar illumination has, for example, at least one light source 1 21 ' that emits green light; at least one light source 12 2 that emits red light; and at least one light source 12 2 that emits blue light. The light source 1 2 1,1 2 2,1 2 3 is, for example, a laser or an electroluminescent diode component or an electroluminescent diode chip, respectively. However, the electroluminescent diode and the laser diode can also be used together as the light source 121, 1 22 ' 1 23 . Flat illumination can also emit more than three or less than three different colors. Furthermore, the total number of light sources 1 2 1, 122, 123 included in the planar illumination can vary. The light beam emitted by the light source can be diverted by the steering element 11 to the imaging element 13 and the projection light path 41. The beam passes, for example, through an integrator 14 and a relay lens 15. The integrator is an optical device whereby the light emitted by an illumination device 12 can be mixed as evenly as possible. For example, the integrator can be a light mixing rod or a honeycomb capacitor. These optical components are known to experts in this field. The electric cymbal 15 is, for example, an optical device or an optical element that substantially images the light emitting face of the integrator 14 on the image forming element 13. The element 13 has, for example, an imaging lens or an imaging lens. The electric cymbal 15 may in particular also be composed of a plurality of parts, for example, it may have a plurality of lenses' lenses for imaging together. Imaging devices or imaging lenses are suitable for use in eMule, which is basically known to experts in the field. -1 5 - 200914984 The element 13 for imaging has, for example, a configuration formed by individually adjustable micromirrors. Each of the micromirrors is arranged, for example, in a matrix form. The micromirrors can, for example, be individually angled and have two stable final forms Is ' to switch between this one final state. Light can be reflected to the photographic objective or not by the inclination of the respective micromirrors. These imaging components have been known to experts in the field and are especially commercially available. Alternatively, the imaging element 13 has, for example, at least one liquid crystal display, which for example comprises two or three LcD_ elements for a liquid crystal projector. Appropriate L C D - components are known to experts in this field. In addition to the conventional LCD-element, the image forming element n may have at least one L C 0 S - element' which also has a liquid crystal, for example, a liquid crystal in the form of a liquid crystal panel. The LC 0 S - element is provided with a mirror that reflects the beam to be projected on the imaging element. On the contrary, the conventional LCD-element is illuminated by the light beam to be projected without the above-described reflection. These imaging components are also known to the expert of the field and are especially commercially available. The illumination beam path shown in Figure 5 shows an illumination of a micro-mirror array (D M D). This configuration, also applicable to L C D and L C 0 S - systems, has been known to experts in this field. In all embodiments, image sensor 6 is, for example, a digital image sensor, which may be a CCD-sensor, CMOS-sensor (also known as active pixel-sensor) , APS - sensor) or any other suitable digital image sensor. A plurality of imaging elements 13 and a plurality of images -16 - 200914984 sensors 6 may be included in the device 1, respectively. For example, three imaging elements can be included, for example, three LCD-elements, and three image sensors, for example, three CCD-sensors. In the embodiment shown in Figs. 5 and 6, the apparatus 1 includes a plurality of switching elements 5, respectively, whereby at least one image sensor 6 can be moved. In the embodiment of Figs. 5 and 6, the image sensor 6 and the imaging element 13 are moved by the switching element 5. When the photographic light path 2 1 is adjusted, the imaging element 13 can be moved, for example, to the side and the image sensor 6 can be moved substantially to the position of the imaging element. When the projection light path 41 is adjusted, the above-described movement can be performed in the reverse direction. The projection light path 4 1 is adjusted in Fig. 5, wherein the light beam to be projected is incident on the element 13 for imaging. The imaging element 13 and/or the image sensor 6 can have a g/sm translation, at least one rotation, and a combination of at least one translation and at least one rotation. Therefore, each element can also be vibrated in the position of _ ^ to replace the movement of each element. Further, the image sensing and measuring unit 6 can move j, for example, in a different manner from the element 13 for imaging.
