[Prior Art] When shooting an image, the size of the aperture is selected to affect the depth of field between the subject and the background (dep1; h of field), and the depth of field is simply when the camera is operated. After focusing, the scene presents a completely clear range of distances on the negative or CCD (Charge Coupled Sensor) / CMOS (complementary MOS sensor) photosensitive elements'. It can also be said that the focus is clear before and after the focus. Metrics, the objects within this distance should be clear, except that the aperture size will affect the depth of the scene, other factors are more like the length of the lens focal length and the distance of the photographic distance. The relationship between depth of field, aperture, focal length and object distance includes (1) the larger the aperture and the shallower the depth of field; (2) the longer the focal length (such as the telescope head) and the shallower the depth of field; (3) the object distance (lens and The closer the distance between the subjects is, the shallower the depth of field is; on the contrary, (1) the smaller the aperture and the deeper the depth of field; (2) the shorter the focal length (such as the macro lens) and the deeper the depth of field; (3) the object distance (lens and The farther the distance between the subjects is, the deeper the depth of field is. As shown in the first figure, the lens 10 represents a lens in the camera. After the focusing process, the object to be photographed is located on the plane 14 where the focus point f is located, and is separated from the lens 10 by a distance, that is, the object distance s, Subject 6 200821743 The reflected/exposed light passes through the lens 1 〇: ^ 隹 projected to the other side of the focus Γ where the focus is flat and the distance between the lens and the lens K) is the image distance /, that is For the position of the photosensitive element such as CCD/CMOS for the transmission plane, the shape === or: The line starts to gather and spread before and after the focus ,, image: production: Chu image. First dry. Relative to the current parameter on the focal plane 12, the range of the ambiguity is formed, and the foreground depth di and the depth of field d2 are formed, and dl and 汜 have a clear d. In other words, the front and back depth of field of the object being photographed is that the image on the depth of field/CCD/CMOS is in a clear range. Therefore, the photographer needs to consider the effect of the depth of field in addition to the consideration when shooting. In addition to the adjustment of φ, the image in (viewFmder) is required: the clear view window is correct, the Jingbing dare function needs to be viewed through the viewing window, and the viewing window will be darker when viewed from the side (because Aperture reflects the amount of light, and is difficult to discriminate = In addition to the shutter mode and aperture priority mode, the prior art is more like the depth of field as disclosed in US Patent No. 5,532,782. Camera having a depth priority operation mode is a technique for calculating the aperture value by using the depth of field, so that objects of different distances in the pupil surface to be ingested can fall within the depth of field of the camera, that is, the technique of focusing with focus. Under the calculated aperture, multiple objects can present a clear image. As shown in the first figure, 'the object a and the object b are marked. On the camera 7 200821743 20, the shutter focus is generally pressed to control the lens focus, and the distance of the object to be focused can be calculated and calculated. The amount of light required. Procedurally, focus on the object a, calculate the distance, and then focus and calculate the distance of another object b in the face, and the camera records the messages. Then, by analyzing the phenomenon of defocus, which object is a close object, then the object a and the object b are both within a depth of field to calculate a minimum aperture value (1/A, A is 2, 2.8, 4, 5.6, 8, 11, 16, etc.), and finally adjust the aperture value to shoot. For the control of the depth of field, the method and apparatus for controlling the depth of field using multiple user interface markers is disclosed in US Patent No. 6,801,717. The technique of selecting two different objects and focusing between the two objects, then adjusting the aperture setting to adjust the depth of field. It discloses a digital camera that allows a user to mark an object in the captured face to control the focal length and aperture thereof, such as marking the first object in the face first, then the focal length is placed on the object, and then marked The second object, which is then focused on the second object, can then be adjusted by the aperture. The setting includes the depth of field of the two objects. SUMMARY OF THE INVENTION Unlike the prior art, the technology disclosed in the depth of field composition setting system and the setting method of the present invention borrows the object on the screen to focus on the subject, and the labeled reference object is set to be fuzzy, showing a utilization. Depth of field setting - the resulting shooting effect. In the embodiment of the present invention, the method step set for the depth of field composition package 8 200821743 line: the main focus is gone and the object distance of the subject is calculated, and then the root distance is estimated after the reference object is entered, and then the depth of field is calculated, and then the aperture value is calculated. Asian and African can satisfy all the conditions, so it is necessary to judge whether the aperture value is appropriate according to the real ρ 汉 system. If it is not appropriate, then take another ί Γ ' 亚 recalculate the other aperture; if the aperture value is appropriate, then [ Embodiments: The depth of field can be used to separate the foreground from the background. The aperture is the most direct factor affecting the depth of field. Therefore, the aperture can be used to achieve the desired depth of field effect, except for the aperture. More ^ The length of the lens focal length and the distance of the photographic distance can cause different depth of field effects. Generally speaking, the depth of field can be determined by controlling the aperture, focal length, and shooting distance. The depth of field is proportional to the aperture value. The larger the aperture value (the smaller the aperture aperture), the larger the depth of field, such as the aperture. The value 16 is about 4 times larger than the depth of field of the aperture value 4; and the depth of field is proportional to the square of the shooting distance. The farther the distance is, the larger the depth of field is, and the square depth is increased. For example, the depth of field at 16 meters is 4 meters. The depth is 16 times larger than the square of the lens. The smaller the focal length, the larger the depth of field, and the squared ratio increases. For example, the depth of field of a 50mm lens is 4 times larger than that of an i00mm lens. However, the present invention provides a depth-of-depth composition setting system and setting method, which is to inversely calculate the required aperture size by actively setting the depth of field size to match the limitation of the camera itself, such as the aperture size limitation, to obtain a 200821743 one. Shoot with the appropriate aperture. „Please refer to the schematic diagram of the image capturing device body shown in the third figure. The preferred embodiment of the present invention particularly uses a touch-screen image capturing device, that is, a viewing touch screen for previewing the facet ( Touch screen), let the user determine the subject matter and the reference object. In other embodiments, the cursor can be controlled by using the direction control keys with up, down, left, and right direction control (the control key 302 in the figure) as the selection subject and reference object. In order to produce the effect of depth of field in the facet, the present invention can use the touch function of the screen 303 to select a subject (such as the main body 307) in the captured face. Clicking on this subject system to select a specific range of areas is a foreground to be clearly presented; and clicking on a reference object (as shown in Figure 308), clicking on this reference is also near the selected position. A specific range of areas is the background to create a blurring effect. Two objects need to occupy a specific range in the facet, and the memory in the image capturing device 30 (such as a digital camera) when clicked (not shown in In the figure, the shutter button 301 is pressed to perform shooting, and in some embodiments, the shutter button 301 is pressed halfway to perform focusing operation. In a preferred embodiment of the present invention, After the main body 307 and the reference object 308 are selected, when the image is to be photographed, the main body 307 and the reference object 308 are respectively focused by the action of pressing the shutter button 301 halfway, and the instant is used when the shutter button 301 is pressed. The calculated aperture is photographed to produce a clear subject 307 and a blurred reference 308, and the effects of the two objects are reversed. The setting button 304 on the image capturing device 30 can perform other shootings other than the aperture. Parameter setting. Please refer to the fourth figure for the depth of field setting diagram of the present invention. When the user 10 200821743 is set on the touch screen of the image capturing device 30 (the above-mentioned component 3〇3), or the direction control key (± The component 3G2) selects a reference object 308 which needs to clearly show the axis main body 307, and the blurring effect caused by the shooting mode in which the focus is not on the focus, def〇cus, and not in the hall, /罙, in this case, in this example, The object 307 is located closer to the image capturing device 30, and the reference object 308 is located farther from the image capturing device 3. In the above figure, after the main object 3〇7 is determined, the image capturing device 3 is performed. Focusing action, in order to make the image clearly appear on the image sensor (CCD or CM0S) in the image capturing device 3,, the lens in the lens (not shown in the figure) is driven to focus, because the ideal optics The imaging formula of the spherical mirror is l/p+l/q= 1/f, where p is the object distance, q is the image distance 'f is the focal length, and the pair is true; |, complete, that is, the focal length f, the image distance q The distance between the image sensor and the spherical mirror is also known, so the object distance p can be easily known, that is, the distance m between the objects in the figure. Similarly, after the reference object is determined, the reference object distance D2 can be known by the focusing operation of the image capturing device 30, and the object spacing D after the subtraction is the absolute value of the difference between the two, in this case, D=D2_D1. u and I produce the effect of a blurred negative scene. The distance d of the object is greater than the depth of field of the image capture device, that is, the depth of field white is estimated to be smaller than the distance D of the object, t襄 reference The object 3〇8> falls outside the depth of field, and can get _image. However, (4) The limitation of the shooting environment and the image capturing device may cause inconsistencies in the degree of blurring. Even if the depth of field requirements are too short to achieve the effect of blurring the reference material, these special links are limited to hardware. And the physical phenomenon is not the subject to be solved by the present invention. Finally, the image is taken with the object _ value calculated from D and other images 200821743 camera 30 settings. The depth of field composition setting system disclosed in the present invention is used in an image capturing device to estimate the aperture value to estimate the aperture value for shooting, and to achieve a background blur effect, wherein the hardware is summarized as follows: driving the image by using the lens driving unit The lens of the camera (including the necessary lens group l. After focusing, the image will be captured through the lens, and then the image sensing unit (such as the charge coupled device sensor (CCD) or complementary MOS semiconductor mounted on the image capturing device) Inductor (CMOS), captures images, and converts them into digital signals (', the image used in the present invention includes at least a subject and a reference, and then should be displayed on a liquid crystal display (LCD) configured by the image capturing device. The preferred embodiment may be a touch screen. During the shooting process, the memory unit may buffer the image captured by the image sensing unit and memorize the selected subject and the reference object. The range, because the subject or reference should occupy a specific range in the face, the focus and distance calculation can be performed, and the film can be stored after shooting. For example, in the preferred embodiment of the present invention, the selection of the main body and the reference object may be selected by the touch screen, or by using the direction key of the camera itself. Controlling the cursor of the screen to select, and after selecting the subject and the reference object, respectively generating marking information for the subject and the reference object on the display screen, the marking information may be different marking symbols or different colors, respectively The selected subject and the reference object temporarily store the mark in the memory. Furthermore, the image capturing device includes a central processing unit for processing each data and signal, which can be achieved by a wafer, received by The image sensing single-element converted image has a vertical signal and is displayed on the liquid crystal display. The image will be stored or memorized in the memory unit, and the functions performed therein include: one or more selected ones. The mark information of the subject and the reference object is memorized in the memory unit, and the selected method includes directly using the touch method on the liquid crystal display Selecting, or using the direction keys to control the cursor to select the object; the central processing unit separately focuses on the subject and the reference object, and uses the imaging formula to calculate the object distance between the subject and the reference, respectively, and then calculates the subject and The distance between the reference objects is further determined by the distance between the subject and the reference object, and is taken by the nose-out aperture value of the depth of field. The preferred embodiment of the present invention performs numerical calculation functions such as distance calculation, depth of field estimation and aperture calculation. It is achieved by a firmware disposed in the image capturing device. As a main step shown in FIG. 5, the main body and the reference object are selected on the screen on the image capturing device, and the preferred embodiment of the present invention utilizes a The image capturing device with the touch screen performs the selection of the main body and the reference object in the facet, and is usually operated on a touch liquid crystal display (LCD). At this time, the preferred embodiment of the present invention is for selecting.
