Description
本發明是有關於一種立體顯示技術,且特別是有關於一種減緩暈眩的立體顯示裝置與立體顯示方法。The present invention relates to a stereoscopic display technology, and particularly to a stereoscopic display device and a stereoscopic display method for reducing dizziness.
虛擬實境(Virtual Reality,VR)是利用電腦模擬產生一個三維空間的虛擬世界,提供使用者關於視覺等感官的模擬,讓使用者感覺彷彿身歷其境,可以即時、沒有限制地觀察三維空間內的事物。然而,現今的虛擬實境技術仍然有許多的問題需要克服,而使用者的暈眩反應則是其中最主要的問題之一。在過去的研究當中,許多原因都可能造成使用者在使用虛擬實境裝置時出現暈眩,且不同使用者的暈眩原因可能各不相同。Virtual reality (Virtual Reality, VR) is the use of computer simulation to generate a virtual world in a three-dimensional space, providing users with visual and other sensory simulations, allowing users to feel as if they are in the real world, and can observe the three-dimensional space in real time and without restrictions Things. However, today's virtual reality technology still has many problems to overcome, and the user's dizzy response is one of the most important problems. In past research, many reasons may cause users to experience dizziness when using virtual reality devices, and the causes of dizziness may vary from user to user.
舉例來說,當眼睛看到畫面正在移動但身體卻未感覺到在移動時,可能造成感官上的不一致而導致暈眩;由於畫面存在延遲(latency)現象,在擺動頭部的過程中轉動時間與畫面實際變化時間中的時間差也可能導致暈眩;每個使用者的瞳距(Interpupillary Distance,IPD)不同,因此使用者在使用虛擬實境裝置時的瞳孔中心、透鏡中心與畫面中心可能不在同一條線上,而出現重影現象導致暈眩;當虛擬實境畫面中的景深與使用者認知不同時,也可能造成暈眩。For example, when the eyes see the picture moving but the body does not feel it moving, it may cause sensory inconsistencies and cause dizziness; due to the phenomenon of latency in the picture, the rotation time during the head swing The time difference with the actual change time of the screen may also cause dizziness; each user's interpupillary distance (IPD) is different, so the user's pupil center, lens center and screen center may not be when using the virtual reality device On the same line, the phenomenon of ghosting causes dizziness; when the depth of field in the virtual reality picture is different from the user's perception, it may also cause dizziness.
由此可知,虛擬實境中可能造成暈眩的原因無法一以蔽之,暈眩解決的相關課題也是本領域技術人員研究的重點。It can be seen from this that the cause of dizziness in virtual reality cannot be overshadowed, and the related issues of dizziness resolution are also the focus of research by those skilled in the art.
有鑑於此,本發明實施例提供一種立體顯示裝置與立體顯示方法,能夠減緩觀看立體動態影像時所產生的暈眩以提升使用者體驗。In view of this, embodiments of the present invention provide a stereoscopic display device and a stereoscopic display method, which can alleviate the dizziness generated when viewing stereoscopic dynamic images to improve the user experience.
本發明實施例的立體顯示裝置包括立體顯示面板以及處理器。立體顯示面板用以顯示具有一視野範圍的立體動態影像。處理器耦接於立體顯示面板並且用以進行暈眩解決方案,包括將立體動態影像朝向立體顯示面板的中心線壓縮,以縮小立體動態影像的橫向寬度並且同時維持其視野範圍。The stereoscopic display device of the embodiment of the present invention includes a stereoscopic display panel and a processor. The stereoscopic display panel is used to display stereoscopic dynamic images with a field of view. The processor is coupled to the stereoscopic display panel and used for dizziness solutions, including compressing the stereoscopic dynamic image toward the centerline of the stereoscopic display panel to reduce the lateral width of the stereoscopic dynamic image while maintaining its field of view.
本發明實施例的立體顯示方法包括以下步驟:顯示具有一視野範圍的立體動態影像;以及進行暈眩解決方案,包括將立體動態影像朝向立體顯示面板的中心線壓縮,以縮小立體動態影像的橫向寬度並且同時維持其視野範圍。The stereoscopic display method according to an embodiment of the present invention includes the following steps: displaying a stereoscopic dynamic image with a field of view; and performing a dizzy solution, including compressing the stereoscopic dynamic image toward the centerline of the stereoscopic display panel to reduce the lateral direction of the stereoscopic dynamic image Width while maintaining its field of view.
基於上述,本發明實施例所提出的立體顯示裝置與立體顯示方法將立體動態影像朝立體顯示面板的中心線壓縮,以縮小立體動態影像的橫向寬度並且同時維持其視野範圍。據此,讓使用者雙眼所看到的影像朝鼻子方向縮窄且不減少其所能看到的影像內容,能夠在使用者不易察覺的情形下透過降低影像的立體感來減緩暈眩,以提升使用者體驗。Based on the above, the stereoscopic display device and the stereoscopic display method proposed in the embodiments of the present invention compress the stereoscopic dynamic image toward the centerline of the stereoscopic display panel, so as to reduce the lateral width of the stereoscopic dynamic image and maintain its field of view. According to this, the image seen by the user's eyes is narrowed toward the nose without reducing the content of the image that they can see, and the dizziness can be reduced by reducing the stereoscopic effect of the image under the situation that the user is not perceptible. To enhance the user experience.
為讓本發明的上述特徵和優點能更明顯易懂,下文特舉實施例,並配合所附圖式作詳細說明如下。In order to make the above-mentioned features and advantages of the present invention more obvious and understandable, the embodiments are specifically described below in conjunction with the accompanying drawings for detailed description as follows.
圖1繪示本發明一實施例中立體顯示裝置的概要方塊圖。FIG. 1 is a schematic block diagram of a stereoscopic display device according to an embodiment of the invention.
請參照圖1,立體顯示裝置100包括處理器110以及立體顯示面板120,其中處理器110耦接於立體顯示面板120。在一些實施例中,立體顯示裝置100例如為虛擬實境(Virtual Reality,VR)顯示裝置,用以顯示立體動態影像。然而,本發明並不在此限制立體顯示裝置100的具體結構與實作方式,所屬技術領域具備通常知識者當可基於虛擬實境等知識來實作立體顯示裝置100。Referring to FIG. 1, the
處理器110可用以發送顯示訊號至立體顯示面板120,以透過立體顯示面板120來顯示立體動態影像。此外,處理器110更用以進行暈眩解決方案,在使用者可能或確實發生暈眩時進行適當的操作來減緩暈眩狀態。在一些實施例中,處理器110例如包括中央處理單元(Central Processing Unit,CPU),或是其他可程式化之一般用途或特殊用途的微處理器(Microprocessor)、數位訊號處理器(Digital Signal Processor,DSP)、可程式化控制器、特殊應用積體電路(Application Specific Integrated Circuits,ASIC)、可程式化邏輯裝置(Programmable Logic Device,PLD)或其他類似裝置或這些裝置的組合,但本發明並不限於此。The
立體顯示面板120例如是由單一面板或多個面板所組成,其耦接於處理器110,可用以接收來自處理器110的顯示訊號以顯示立體動態影像。在一些實施例中,立體顯示面板120實作於頭戴式顯示器中,用以分別提供具有視差的兩影像至使用者雙眼。在一些實施例中,如圖3所示,立體顯示面板120包括多個面板(例如,第一面板P1與第二面板P2),其中立體顯示面板120的中心線CL以左的面板(例如,第一面板P1)用以提供左動態影像至使用者的左眼,而中心線CL以右的面板(例如,第二面板P2)用以提供右動態影像至使用者的右眼。值得一提的是,上述立體顯示面板120的中心線CL是位於使用者正常觀看立體顯示面板120時雙眼連線的垂直平分面上且垂直於視平面(horizontal plane)的假想直線。然而,本發明並不在此限,所屬領域具備通常知識者當可依其立體顯示的知識來實作立體顯示面板120。The
圖2繪示本發明一實施例的立體顯示方法的流程圖。FIG. 2 is a flowchart of a stereoscopic display method according to an embodiment of the invention.
請參照圖2,在步驟S110中,處理器110會發送顯示訊號至立體顯示面板120,而立體顯示面板120會根據所接收的顯示訊號來顯示立體動態影像。與此同時,在步驟S120中,處理器110會透過決定使用者的暈眩狀態,並且在步驟S130中基於所決定的暈眩狀態來進行暈眩解決方案。Referring to FIG. 2, in step S110, the
具體來說,在透過立體顯示面板120顯示立體動態影像的同時,處理器110會決定使用者的暈眩狀態,包括預測使用者是否可能發生暈眩或判斷使用者是否發生暈眩。舉例來說,當立體動態影像的影像內容變動或視野切換的頻率越高時,使用者越有可能發生暈眩,因此在一些實施例中,處理器110可例如是直接根據顯示訊號的內容,來預測立體顯示面板120所顯示的立體動態影像是否可能造成使用者暈眩以決定暈眩狀態。此外,當暈眩發生時會產生特定的生理反應,例如腦波變化、血氧濃度降低、瞳孔放大或眨眼頻率上升等等。因此,在一些實施例中,處理器110亦可例如是偵測使用者實際的生理反應來判斷使用者是否發生暈眩。在決定了使用者的暈眩狀態後,處理器110會在暈眩狀態表示使用者可能發生暈眩或已經發生暈眩時進行暈眩解決方案來嘗試減緩使用者的暈眩。在後續段落中將搭配圖式舉實施例說明決定暈眩狀態的具體方式。Specifically, while displaying the stereoscopic dynamic image through the
在一些實施例中,處理器110進行暈眩解決方案時,會將立體動態影像朝向立體顯示面板120的中心線CL壓縮,以縮小立體動態影像的橫向寬度並且同時維持視野範圍。In some embodiments, when the

在上述的暈眩解決方案中,立體動態影像的視野範圍不變,但使用者的視線夾角縮小。據此,可以減少使用者所感受到的立體感而減輕暈眩感受。In the aforementioned dizziness solution, the field of view of the stereoscopic dynamic image is unchanged, but the angle of the user's line of sight is reduced. According to this, the three-dimensional feeling felt by the user can be reduced and the feeling of dizziness can be reduced.
在一些實施例中,立體顯示面板120例如包括多個面板。處理器110進行暈眩解決方案時,例如會判斷此些面板的影像更新率(frame rate)是否相同。若此些面板的影像更新率不同,則處理器110會在進行暈眩解決方案時將此些面板的影像更新率調整為相同的影像更新率。In some embodiments, the
在一些實施例中,立體顯示面板120例如包括多個面板。處理器110進行暈眩解決方案時,例如會判斷此些面板的掃描線方向是否相同。若此些面板的掃描線方向不同,則處理器110會在進行暈眩解決方案時將此些面板的掃描線方向調整為相同的掃描線方向。In some embodiments, the

The
第二處理器110b是用以控制眼動儀140的整體運作並執行與眼動儀140相關的功能。在一些實施例中,第二處理器110b例如包括中央處理單元(Central Processing Unit,CPU),或是其他可程式化之一般用途或特殊用途的微處理器(Microprocessor)、數位訊號處理器(Digital Signal Processor,DSP)、可程式化控制器、特殊應用積體電路(Application Specific Integrated Circuits,ASIC)、可程式化邏輯裝置(Programmable Logic Device,PLD)或其他類似裝置或這些裝置的組合,但本發明並不限於此。The
值得一提的是,圖6實施例是以功能來區分第一處理器110a與第二處理器110b,但本發明並不限制第一處理器110a與第二處理器110b的具體實作方式。舉例來說,第一處理器110a與第二處理器110b可以兩個獨立的晶片來實作,也可以是整合於同一個處理器晶片當中。It is worth mentioning that the embodiment of FIG. 6 distinguishes the first processor 110a and the
影像擷取裝置130例如是設置於鄰近立體顯示面板120處,用以擷取使用者的眼睛影像。在一些實施例中,影像擷取裝置130包括鏡頭以及感光元件。感光元件例如是電荷耦合元件(Charge Coupled Device,CCD)、互補性氧化金屬半導體(Complementary Metal-Oxide Semiconductor,CMOS)元件或其他元件,影像擷取裝置130還可包括光圈等,在此皆不設限。在一些實施例中,影像擷取裝置130例如包括左影像擷取裝置以及右影像擷取裝置,分別對應於立體顯示面板120的第一面板P1以及第二面板P2設置,以取得包括使用者左眼以及右眼的眼睛影像。The
圖7繪示本發明一實施例中立體顯示方法的流程圖。7 is a flowchart of a stereoscopic display method according to an embodiment of the invention.
請參照圖7,在步驟S210中,立體顯示面板120顯示立體動態影像,並且同時影像擷取裝置130取得使用者的眼睛影像。隨後在步驟S220中,分析眼睛影像以取得瞳孔大小以及眨眼率。Referring to FIG. 7, in step S210, the
具體來說,第一處理器110a會發送顯示訊號至立體顯示面板120,而立體顯示面板120會根據所接收的顯示訊號來顯示立體動態影像。與此同時,第二處理器110b會透過影像擷取裝置130隨時間取得多張使用者的眼睛影像,並且分析所取得的多張眼睛影像以找出此些眼睛影像中的瞳孔位置。Specifically, the first processor 110a sends a display signal to the
圖8繪示本發明一實施例中眼睛影像的示意圖。8 is a schematic diagram of an eye image in an embodiment of the invention.
請參照圖8,在一些實施例中,第二處理器110b例如會對眼睛影像進行霍夫轉換(Hough transform)等分析來找出左瞳孔PL與右瞳孔PR的位置,然後針對左瞳孔PL記錄左瞳孔上緣的座標與左瞳孔下緣LD的座標,以及針對右瞳孔PR記錄右瞳孔上緣RU與右瞳孔下緣RD的座標。Referring to FIG. 8, in some embodiments, the
隨後,第二處理器110b會將眼睛影像的左上方座標LU、左下方座標LD、右上方座標RU與右下方座標RD告知第一處理器110a。如此一來,第一處理器110a便能夠根據一段時間內的多張眼睛影像的左上方座標LU、左下方座標LD、右上方座標RU與右下方座標RD得知使用者在這段時間內的瞳孔大小以及眨眼頻率。然而,本發明並不在此限制第一處理器110a在取得來自眼動儀140的資料後,分析出瞳孔大小與眨眼頻率的具體方式,所屬技術領域具備通常知識者當可依其需求來進行實作。Subsequently, the
值得一提的是,上述的瞳孔大小可例如是取左眼的瞳孔大小、右眼的瞳孔大小或雙眼的瞳孔大小平均作為代表,而眨眼頻率亦可例如是取左眼的眨眼頻率、右眼的眨眼頻率或雙眼的眨眼頻率平均作為代表,本發明並不在此限制。It is worth mentioning that the above-mentioned pupil size can be taken as the representative of the pupil size of the left eye, the pupil size of the right eye or the pupil size of both eyes as an example, and the blink frequency can also be taken as the blink rate of the left eye, right The blinking frequency of the eye or the blinking frequency of both eyes is representative, and the invention is not limited thereto.
在步驟S230與步驟S240中,第一處理器110a會基於瞳孔大小與眨眼頻率來決定使用者的暈眩狀態,並且在判斷使用者發生暈眩時進入步驟S250以進行暈眩解決方案。詳細來說,在步驟S230中,第一處理器110a會判斷瞳孔大小是否大於第一閥值。若判斷瞳孔大小大於第一閥值,則進入步驟S240進一步判斷眨眼頻率是否高於第二閥值。若判斷眨眼頻率高於第二閥值,則判斷使用者發生暈眩並且進入步驟S250來進行暈眩解決方案。本文已於前述段落中舉實施例詳述暈眩解決方案的細節,故在此不再贅述。In steps S230 and S240, the first processor 110a determines the dizziness state of the user based on the pupil size and the blinking frequency, and proceeds to step S250 to determine the dizziness when the user is dizzy. In detail, in step S230, the first processor 110a determines whether the pupil size is greater than the first threshold. If it is determined that the pupil size is greater than the first threshold, step S240 is entered to further determine whether the blink frequency is higher than the second threshold. If it is determined that the blink frequency is higher than the second threshold, it is determined that the user has dizziness and proceeds to step S250 to perform the dizziness solution. This article has given examples in the preceding paragraphs to elaborate on the details of the dizziness solution, so it will not be repeated here.
在一些實施例中,第一處理器110a例如會取立體顯示面板120開始顯示立體動態影像的前一段時間(例如但不限於,前1分鐘的時間段等)中的瞳孔大小平均值作為正常瞳孔大小,並且將此正常瞳孔大小乘上第一倍率(例如但不限於,1.05至1.1)以作為第一閥值。第一處理器110a例如會計算相同的時間段(例如,1分鐘)中平均瞳孔大小來與第一閥值作比較,並且在所計算的平均瞳孔大小大於第一閥值時判斷瞳孔大小大於第一閥值。在一些實施例中,第一處理器110也可例如是預設一個固定的瞳孔大小作為第一閥值,本發明並不在此限。In some embodiments, for example, the first processor 110a may take the average pupil size in the previous period of time (such as but not limited to, the period of 1 minute before, etc.) of the
類似地,在一些實施例中,第一處理器110a例如會取立體顯示面板120開始顯示立體動態影像的前一段時間(例如但不限於,前1分鐘的時間段等)中的眨眼頻率平均值作為正常眨眼頻率,並且將此正常眨眼頻率乘上第二倍率(例如但不限於,1.33)以作為第二閥值。第一處理器110a例如會計算相同的時間段(例如,1分鐘)中的平均眨眼頻率來與第二閥值作比較,並且在所計算的平均眨眼頻率高於第二閥值時判斷眨眼頻率高於第二閥值。在一些實施例中,第一處理器110也可例如是預設一個固定的眨眼頻率作為第二閥值,本發明並不在此限。Similarly, in some embodiments, the first processor 110a may, for example, take the average value of the blink frequency in the previous period (eg, but not limited to, the period of the previous 1 minute, etc.) when the
值得一提的是,除了暈眩狀態之外,瞳孔大小還可能因為其他因素而發生改變,例如,因立體動態影像的整體亮度降低而造成瞳孔大小放大。特別是,立體動態影像的整體亮度降低並不會造成使用者的眨眼頻率上升。因此,本發明實施例更在瞳孔大小大於第一閥值後進一步判斷眨眼頻率,並且在眨眼頻率也高於第二閥值時才判斷使用者發生暈眩。據此,能夠提高判斷暈眩狀態的準確度,以避免在不必要的時候降低立體動態影像的立體感而降低使用者體驗。It is worth mentioning that, in addition to the dizziness state, the pupil size may also change due to other factors, for example, the pupil size is enlarged due to the reduction of the overall brightness of the stereoscopic dynamic image. In particular, the reduction in the overall brightness of the stereoscopic dynamic image does not cause the user's blink frequency to increase. Therefore, in this embodiment of the present invention, the blink frequency is further determined after the pupil size is greater than the first threshold, and the user is dizzy when the blink frequency is also higher than the second threshold. According to this, the accuracy of determining the dizziness state can be improved to avoid reducing the stereoscopic effect of the stereoscopic dynamic image when it is unnecessary and reducing the user experience.
若第一處理器110在步驟S230中判斷瞳孔大小不大於第一閥值,或在步驟S240中判斷眨眼頻率不大於第二閥值,則進入步驟S260來將立體顯示裝置200回復為原始狀態。If the
具體來說,若第一處理器110在步驟S230中判斷瞳孔大小不大於第一閥值,或在步驟S240中判斷眨眼頻率不大於第二閥值,表示使用者並未發生暈眩或暈眩已經得到緩解。因此,第一處理器110會使立體顯示裝置200回復到進行暈眩解決方案前的狀態。例如,恢復立體動態影像的橫向寬度、恢復立體顯示面板120中多個面板的影像更新率或掃描線方向等。Specifically, if the
綜上所述,本發明實施例所提出的立體顯示裝置與立體顯示方法將立體動態影像朝立體顯示面板的中心線壓縮,以縮小立體動態影像的橫向寬度並且同時維持其視野範圍。據此,讓使用者雙眼所看到的影像朝鼻子方向縮窄且不減少其所能看到的影像內容,能夠在使用者不易察覺的情形下透過降低影像的立體感來減緩暈眩,以提升使用者體驗。在一些實施例中,立體顯示裝置與立體顯示方法更分析使用者的眼睛影像來同時根據瞳孔大小與眨眼頻率判斷使用者是否發生暈眩。據此,能夠在正確的時間點進行暈眩解決方案。In summary, the stereoscopic display device and the stereoscopic display method according to the embodiments of the present invention compress the stereoscopic dynamic image toward the centerline of the stereoscopic display panel, so as to reduce the lateral width of the stereoscopic dynamic image and maintain the field of view. According to this, the image seen by the user's eyes is narrowed toward the nose without reducing the content of the image that they can see, and the dizziness can be reduced by reducing the stereoscopic effect of the image under the situation that the user is not perceptible. To enhance the user experience. In some embodiments, the stereoscopic display device and the stereoscopic display method further analyze the user's eye image to determine whether the user is dizzy according to the pupil size and blink frequency. According to this, the dizzy solution can be performed at the right time.
