Description of the Invention: [Technical Field] The present invention relates to an image capturing technique, and more particularly to an image capturing device, an autofocus module, and an autofocusing unit that can adjust a viewing range as the object moves. [Prior Art] A conventional video camera, a camera, or a network camera for a computer can capture a dynamic image by directly driving the camera or moving the camera through a mechanical hinge to capture the image. However, the focus frame is a solid range. The disadvantage is that when the subject moves too fast or too close to the camera, the object will leave the focus frame, causing the shot to be less than expected by the user. As shown in the first figure, the general photographing device 1 is mounted on the stand 2, and the photographing direction of the photographing device i can be controlled by the control-control knob 3, and the focus frame of the photographing device i is as shown in FIG. When the subject moves too fast, as shown in the second B picture, the subject is half-in the focus frame, and half is outside the focus frame, and the quality of the shot depends on the user's operation skill. In recent years, there has been a photographic device that automatically detects the dynamics of a subject, which is fixed on a rotating shaft device, can detect the movement of the object, and controls the rotating shaft to drive the entire photographic device to rotate, and along with the subject The change automatically adjusts the optical focus. Although the above-mentioned photographing apparatus can overcome the deficiencies of the user's operation skills in the prior art, the photographing apparatus incorporated in the hinge apparatus cannot be applied to the sticking difficulty which can be easily taken by a general user. First of all, the above-mentioned photographic equipment must rotate the shaft and optically f, 'the power of f is very large' - the age of the body is not likely to set the battery power; X, the above-mentioned photographic equipment and the reduction of money This is very high, in addition to 201105123 hardware must also have a complicated electromechanical control system; camera and shaft device prefabricated as the same equipment or assembly, whether it is the shooting of the tracking target function, must carry a lot of The user wants to use it from the general user. Therefore, it is very difficult. Therefore, how to improve the above shortcomings about the shortcomings of dynamic shooting. It is nowadays to be answered] Ben Maoming - the purpose is to provide a kind of automatic grouping, autofocus method, and image capture device, singular focus to open the focus frame, to avoid being noticed by the subject The image in the frame is incomplete. In addition, it is a further object of the present invention to provide a movable focus module, an autofocus method, and an image capture device package. EFFICIENCY AND COSTS Another object of the present invention is to provide an "autofocus module", an autofocus method, a general user operation of τ/, and an image capture device. In order to achieve the above and other objects set in an image capturing device, the sun and the moon provide an automatic focus mode which has a set-of-the-view range=°Bet"--with the image-sensing module corresponding to -f彡 , , , 自 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 取 取 取 取 取 取 取 取 取 取 取 ^ ^ ^ '·—Moving the fine unit, the second dry garden, the first viewfinder Fan and at least the package, the target moving object C calculation unit _, used to detect the moving fine early 妾, used to = according to the direction And a processing unit that adjusts the position of the second viewing range 201105123 within the first viewing range with the moving direction of the shifting π to keep the target within the second viewing range. The present invention provides an image capturing device suitable for photography and photography. The system includes the image sensing module, the auto focus module, and the display unit, wherein the auto focus module and the image capturing unit and the display unit respectively Coupling. The present invention further provides an autofocus method, the method comprising: setting a first framing range, locking a target in the first framing range, and generating a second framing range according to the target size by the autofocus module; The image of the two framing range is magnified by the digital zoom and displayed on the display unit, and then the target is moved. If the target is in the moving state, the second framing range moves with the moving direction of the target, so that the target remains at the first position. Within the scope of the second view. Thereby, the second framing range is moved by following the movement of the object, so that the framing can be dynamically performed without the user controlling the direction of the image capturing device. In this way, it is possible to solve the problem that the target is out of the framing range, and the framing operation unit can obtain the size of the appropriate second framing range according to the size of the object. Further, the present invention can save the power required for driving the rotating shaft and the cost of additional equipment as compared with the photographic apparatus having a rotating shaft in the prior art. Furthermore, the present invention is more portable and can be spread to users than the photographic apparatus assembled with the shaft device in the prior art. As can be seen from the above, the autofocus module, the autofocus method, and the image capturing device of the present invention can sufficiently solve the disadvantages of the prior art. 201105123 The above summary and the following detailed description a further describes the scope of the patent application of the present invention. And the right:: nature' is for the purpose and advantages, and will be further described in the following description and illustration.

Referring to the third figure, the image capturing device of the present invention ίο The auto-focusing module 120 can include a framing operation unit 121, a motion detection unit 123, a face detection unit 125, and a processing unit 127. The motion detection unit 123 is coupled to the framing operation unit 121, and the processing unit 127 Separately and mobile The detecting unit 123 and the face detecting unit 125 are connected. Please refer to the fourth to fourth E and the fourth to fourth E1, and the fourth to fourth E are the actual viewing range. The displayed facet is the face of the first view range, and the fourth A1 figure to the fourth E1 figure are the pictures displayed by the second view range after the digital zoom is enlarged from the fourth A picture to the fourth E picture. As shown in the fourth A diagram and the fourth A1 diagram, the framing operation unit 121 calculates the size of the second framing range according to the target size in the first framing range, that is, according to the target size of the image in the actual framing range. At least a second viewing range of the target object, wherein the aspect ratio of the first viewing range may be built-in preset or adjusted by the user; as shown in the fourth B and fourth B1, the target moves to the left, moving The detecting unit 123 detects the moving direction of the target in the first viewing range, and the processing unit 127 determines whether the target in the first viewing range has moved, and adjusts the position of the second viewing range according to the moving direction of the target to make the target Keep the object within the second view range As shown in the fourth C, D, and fourth Cl, D1, when the target moves, the face detecting unit 125 detects a face other than the target, and the processing unit 127 determines whether there is a target other than the target. The face is close to the second framing range, and the size of the second framing range is adjusted according to the number of faces close to the second framing range. If the number of faces other than the target increases, the second framing range is expanded to make the second framing The range includes at least a target object and a person other than the target object; as shown in the fourth E map and the fourth E1 map 201105123, the processing unit 127 determines whether a face other than the target object leaves the second viewing range and decreases according to the framing range. The number of faces is reduced by the second framing range 'so that the second framing range contains at least the target. The determination of whether the face other than the target is close to the second viewing range may be detected by the face detecting unit 125 for a face other than the target within a preset range, wherein the preset range is __ at least The range of the second framing range and the range around the second framing range is determined by the processing unit 127 whether the preset range is entered, the preset range can be built-in preset or adjusted by the user. The sophomore framing range moves 'whether the target object (4) Or the face of the private object 0 Bu moves, as long as the target is stunned: the default range, then the single-handed break is the face of the face = (2);: the sample plot 'determines whether there is something other than the target:: In the preset range, the face detection unit = fan face or person (four) is lost, and the financial unit m ^ = 取 positive range of view.峤Being a human face to leave the second: Refer to the fifth figure ’ for the flow chart of the consistent embodiment provided by the present invention. As shown in the fifth figure, the steps of the self-focusing method include that the image capturing device 1G enters the self-focusing method by the image capturing shirt 1G (four) and then uses the definition-the first viewing range. (Read), Yudan shirt like the sensing board group is called the target object, for example, face, then = according to the size of the object to calculate H framing * different speeds (2) The second framing range is smaller than the first framing range and at least package A Small (S5G3)' where the first range is magnified by the digital plane: the target, the second viewfinder, and the target can be human, for the user to move the animal next time, move 201105123 detection unit 123 The moving direction of the target in the first viewing range is measured. Then, the target is tracked, and the processing unit 127 determines whether the target moves (S505). If the target is in the moving state, the processing unit 127 moves according to the object. Adjusting the position of the second framing range (S5〇7) to keep the target 2 in the second framing range; if the target is in a non-moving state, or the distance between the target and the image capturing device changes, the target is re-targeted. Object in Take a hall, has a ratio of the size around the primary calculate the size range of the second view, where a single process 127 re-adjust the size of the second viewing range (S503). The closer the ί standard is to the image capture device 10 or the smaller the first framing range, the smaller the ratio of the target in the first framing range, the more the first framing range is in the first framing. The range that can be moved within the range is the opposite. When the target is farther away from the image capturing device or the first image is wider, the target is in the range of the first viewing range. The smaller the case, the larger the range in which the first framing range can be moved within the first framing range. Once the image capture device HM is set to remain unchanged during the shooting process, the object in the first frame may move or other faces other than the target may move, and the target and the target are other than the target. The face relative position is changed and handed over, and the face _ unit 125 detects a face other than the target within a preset range of one of the second framing ranges. The processing unit 127 determines whether there is a face other than the target. The second framing range, that is, the face other than the target in the first framing range (S5〇9), if another face is detected: near the second finder, the processing unit 127 detects the The size of the second framing range is adjusted, that is, the more the number of faces close to the second framing range is measured, the more the second framing range is expanded, so that the second framing range is at least 201105123 π#&t and A person other than the target of the second framing range (S511), the movement of the object continues _ the moving direction of the object ‘with the target 盥i or 疋 the target does not move, the other face positions move, the target object 2: ^ The relative position of the face changes, the processing unit 127 judges Whether the number of faces other than the preset range J^27 is changed (S513). If the number of faces other than the target within the range of 1 fi μ is changed, the basis is selected. He personally Yang face number adjusts the second viewfinder '511), if the detected face +, the head it '(4) large ^ framing range; if the number of faces to the side is reduced ^ Ms small second framing Range; if the number of faces is not changed, the framing range remains unchanged (S515), and the processing of the single illusion 27 is judged automatically: if the if is stopped (S517), if the auto focus mode is continued, the judgment is returned: 1 Yes! Move (S505); if the auto focus mode is stopped, the focus will be restored: 丄/7, |& has only the first framing range (8) (9), that is, the horizontal framing range that has not passed the digit. According to the method of the above-exemplified embodiments, it can be seen that the present invention is capable of moving the target object in accordance with the purpose of the target range, so that the target is kept within the framing range, and by judging the target object. The face is close to: or open the view range to dynamically adjust the viewfinder size, so that the target and the face outside the target can be dynamically entered into the view range. Thus, the image rest of the present invention can solve the traditional need for mechanical moving images. The capture device is used to control the direction of the camera. Because the target object moves too fast, the target object leaves the hall and the range occurs, causing the problem that the camera face is not as expected.
