The image signal acquired by the imaging device 20 is processed by the signal processing circuit 24 and the image processor 26 and stored in the memory 210 or displayed by the display screen 28. The auxiliary composition controller 212 processes the captured image within the memory 210 to form a plurality of reference images 250 (see FIG. 5) and displays them on the display screen 28. The timing signal generator 22 generates timing signals to coordinate the operation of the entire photographing system 2. The data/signal busbars 214 are respectively coupled to different components for exchanging data and control signals between different components.
所述拍攝裝置20包括鏡頭200、驅動器202及影像感測器204。所述驅動器202根據所述自動對焦控制器213的控制信號驅動鏡頭200沿拍攝裝置20的光軸運動，以將被攝物自動對焦在影像感測器204上。所述影像感測器204以預定的時序間隔將對應被攝物體光學像的類比圖像信號輸出至信號處理電路24。The photographing device 20 includes a lens 200, a driver 202, and an image sensor 204. The driver 202 drives the lens 200 to move along the optical axis of the imaging device 20 according to the control signal of the auto focus controller 213 to automatically focus the subject on the image sensor 204. The image sensor 204 outputs an analog image signal corresponding to the optical image of the subject to the signal processing circuit 24 at predetermined timing intervals.
所述信號處理電路24包括相關雙取樣電路(Correlated Double Sampling,CDS)和數模轉換器。所述CDS電路藉由相關雙取樣將包含於影像感測器204輸出的類比圖像信號內的噪音信號去除。所述數模轉換器將已去除噪音的類比圖像信號轉換為數位信號，並將轉換成數位信號的數位圖像信號輸出至圖像處理器26。The signal processing circuit 24 includes a Correlated Double Sampling (CDS) and a digital to analog converter. The CDS circuit removes the noise signal contained in the analog image signal output by the image sensor 204 by correlated double sampling. The digital-to-analog converter converts the noise-reduced analog image signal into a digital signal, and outputs the digital image signal converted into a digital signal to the image processor 26.

The image data composed of the YUV signals is sequentially stored in the memory 210, or converted into a video signal and sent to the display screen 28 for display.
所述自動對焦控制器213控制所述驅動器202的轉動步數以帶動鏡頭200按一定的速度沿光軸方向移動，並當驅動器202轉動到預設的步數時藉由影像感測器204獲取圖像。所述自動對焦控制器213藉由比較分析不同步數所對應的圖像的對比度，以選擇獲取最大對比度圖像時驅動器202的步數作為鏡頭200對焦的位置。The auto-focus controller 213 controls the number of rotation steps of the driver 202 to drive the lens 200 to move along the optical axis direction at a certain speed, and is acquired by the image sensor 204 when the driver 202 rotates to a preset number of steps. image. The autofocus controller 213 compares the contrast of the image corresponding to the unsynchronized number to select the number of steps of the driver 202 when the maximum contrast image is acquired as the position at which the lens 200 focuses.
因為在自動對焦的過程中以驅動器202的步數作為比較判斷的基準，所以驅動器202的步數與在該步數下實現對焦的物距和像距之間存在一一對應的關係。該對應關係由廠家測得並存儲在所述記憶體210內。因此，在實現自動對焦後藉由檢測驅動器202的步數便可得知當前拍攝的物距和像距。Since the number of steps of the driver 202 is used as a reference for comparison judgment during the autofocus process, there is a one-to-one correspondence between the number of steps of the driver 202 and the object distance and image distance at which the focus is achieved.

請一併請參見圖2，所述人臉定位模組2121將影像感測器2049(參見圖1)的成像面2040的左上角的圖元單位所在的位置定義為一座標原點，以水準向右為X軸正方向，垂直向下為Y軸正方向建立一定位坐標系。所述人臉定位模組2121藉由檢測所述人臉區域的兩條對角線相交點H在該定位坐標系內的座標(X h ,Y h )以確定所述人臉區域的中心位置。Please refer to FIG. 2 together, the face positioning module 2121 defines the position of the element unit in the upper left corner of the imaging surface 2040 of the image sensor 2049 (see FIG. 1) as a standard origin. To the right is the positive direction of the X-axis, and vertically downwards to establish a positioning coordinate system for the positive direction of the Y-axis. The face positioning module 2121 determines a center position of the face region by detecting a coordinate ( X h , Y h ) of two diagonal intersection points H of the face region in the positioning coordinate system. .

The distance calculation module 2122 divides the imaging surface 2040 of the image sensor 204 into nine equal regions by two horizontal lines and two vertical lines that are perpendicular to each other, and vertically and horizontally. The four points intersecting are preset to the composition reference point 2041 on the imaging plane. The coordinates of the four composition reference points 2041 in the positioning coordinate system are: ( X i , Y i ), i=1, 2, 3, 4.
所述距離計算模組2122分別計算人臉區域的中心位置H與所述構圖參考點2041在成像面2040上的距離D i =|(X h ,Yh )-(X i ,Y i )|，i=1,2,3,4。The distance calculation module 2122 calculates a distance D i =|( X h , Yh )-( X i , Y i )| of the center position H of the face region and the composition reference point 2041 on the imaging surface 2040, respectively. i=1, 2, 3, 4.
所述移動資料計算模組2123藉由檢測驅動器202的對焦步數並查對記憶體210內的驅動器202的步數與對焦物距和像距的對應關係從而得到當前拍攝裝置20進行拍攝的物距P和像距F。The mobile data computing module 2123 obtains the photographing step of the driver 202 and checks the correspondence between the number of steps of the driver 202 in the memory 210 and the focus distance and the image distance to obtain a photograph taken by the current photographing device 20. Distance P and image distance F.
請一併參見圖3，根據成像光路圖，被攝物與其在成像面2040上所成圖像滿足相似三角形的對應關係。因此，移動資料計算模組2123根據人臉區域的中心位置H與所述構圖參考點2041在成像面2040上的距離D i 藉由三角函數運算可計算得到為了拍攝出人臉區域位於所述構圖參考點2041上的圖像而被攝物需要移動的距離L。Referring to FIG. 3 together, according to the imaging light path diagram, the image formed by the object and the image formed on the imaging surface 2040 satisfies the similar triangle. Therefore, the mobile data calculation module 2123 can calculate, according to the central position H of the face region and the distance D i of the composition reference point 2041 on the imaging surface 2040, by trigonometric function calculation, in order to capture the face region located in the composition. The distance L at which the subject needs to move by referring to the image on the point 2041.
請一併參見圖4，所述移動資料計算模組2123將所述距離L在以人臉區域的中心位置H為原點，水準向右為X軸正方向，豎直向上為Y軸正方向的移動參考坐標系中表示為X L ，Y L 。其中X L 表示被攝物需要沿移動參考坐標系X軸移動的距離，Y L 表示被攝物需要沿移動參考坐標系Y軸移動的距離。Referring to FIG. 4 together, the mobile data calculation module 2123 uses the distance L as the origin of the center position H of the face region, the right direction is the positive direction of the X axis, and the vertical direction is the positive direction of the Y axis. The moving reference coordinate system is represented as X L , Y L . Where X L represents the distance the subject needs to move along the X axis of the moving reference coordinate system, and Y L represents the distance the subject needs to move along the Y axis of the moving reference coordinate system.
因為被攝物在拍攝圖像中的位置取決於被攝物與拍攝系統2之間的相對位置，所以被攝物相對拍攝系統2移動距離L的拍攝效果相當於拍攝系統2相對被攝物朝相反的方向移動距離L的拍攝效果。而在拍攝過程中拍攝者進行移動更為方便，因此，移動資料計算模組2123分別取，便可得到為了拍攝出人臉區域位於所述構圖參考點2041上的圖像而需要對拍攝系統2進行位置移動的相關資料。Since the position of the subject in the captured image depends on the relative position between the subject and the photographing system 2, the photographing effect of the subject moving relative to the photographing system 2 is equivalent to the photographing system 2 with respect to the subject The opposite direction moves the shooting effect of the distance L. It is more convenient for the photographer to move during the shooting process. Therefore, the mobile data computing module 2123 takes each , It is possible to obtain related information for moving the position of the photographing system 2 in order to photograph an image in which the face region is located on the composition reference point 2041.
請一併參見圖5，所述構圖模組2124對由人臉定位模組2121所識別出的人臉區域部分的圖像進行複製。所述構圖模組2124進一步將複製的人臉區域依次覆蓋在原拍攝圖像與所述構圖參考點2041對應的位置處，以形成多幅人臉區域分別位於所述構圖參考點2041處的參考圖像250並將所述參考圖像250存儲在記憶體210內。Referring to FIG. 5 together, the composition module 2124 copies the image of the face region portion recognized by the face positioning module 2121.

The image 250 is stored in the memory 210.
所述顯示模組2125根據距離計算模組2122所設定的構圖參考點2041的個數將顯示幕28劃分為複數個相等的顯示區域280。在本實施方式中，所述構圖參考點2041的個數為四個。因此，所述顯示幕28被相互垂直的十字交叉線劃分為四個相等的矩形顯示區域280。所述顯示模組2125將由構圖模組形成的複數個參考圖像250以及移動資料計算模組2123計算出的拍攝所述不同參考圖像250時拍攝系統的位置移動資料分別顯示在所述顯示區域280內。The display module 2125 divides the display screen 28 into a plurality of equal display areas 280 according to the number of composition reference points 2041 set by the distance calculation module 2122. In the present embodiment, the number of the composition reference points 2041 is four.
