Description of the Invention: [Technical Field] The present invention relates to a camera, and more particularly to a camera which can effectively improve the success rate of self-timer. The present invention also provides a self-timer method using the camera. [Prior Art] ❹ With the digitalization and networking of information technology, digital cameras have developed by leaps and bounds, becoming an indispensable tool for human beings to enter the information age in their work and life. Although digital camera technology continues to mature, iron, its self-function is still only a simple time to take pictures, in this self-timer mode =,, the photographer is often in a very passive shooting state. Because the self-timer mode - ΓΓί ' will automatically shoot after a certain delay, but there will be other people or objects in the shooting scene during the shooting, so as to cover the r photographer, when these people enter the shooting scene : The camera will take these not to shoot = ❿: The success rate of the self-timer is greatly reduced, bringing the photographer a very second. [Inventive content] In view of this, there must be an i4 camera and a kind of use:::::: : Effectively improve the self-timer success rate, ==? head unit, sensing unit, image processing unit, and U and storage unit. Or the plurality of sets of lenses focus the image to be taken and imaged in the group of the sensing unit for sensing by the 隹 = early. The image to be captured on the sensing unit is focused and projected to convert the cut image into an image 200939745 (4) Transmitted to the processing unit. The image is sensed by the sensing unit, and the processing is processed by the ‘number or stored in the storage unit: image: storage image. The self-timer unit is used for the shooting process to: 兀, sensing unit, image processing unit, and storage list=the early self-timer unit further includes a delay module, an image acquisition module, a shifting group, and an overtime module. The motion detection module is used to enable the camera to enter the (four) photo when the self-timer is turned on. The time-lapse acquisition module is used to continuously acquire the processed image signal, thereby obtaining a plurality of image processing units and transmitting the acquired image signal to the detected; = signal, dynamic measurement analysis . Moving in the module The motion detection module is used to capture the image signal acquired by the self-timer image acquisition module, thereby breaking the object into the scene to be shot. The time-sharing module of the moving, moving, and moving moves to the time-lapse time value by adding a pre-camera self-timer method to the delay time value, which includes the following steps: Function, enter the self-timer delay state; obtain the continuous image transmission at different times after the lens unit and the sensing unit are imaged and processed at the same time. The moving image analysis is performed on the acquired continuous image signal, _ is 200939745 Whether there is a moving object falling into the scene to be shot; If there is no moving object into the scene to be shot, it is judged whether the self-timer is over; if the self-timer is over, the camera is executed and the captured image is stored; if the self-timer is delayed If the moving object is in the scene to be shot, the delay time value is increased by a predetermined length of time, and it is determined again whether there is a moving object falling into the to-be-shooted scene. Compared with the prior art, the present invention adds a motion detection module to the self-timer unit to detect whether a moving object breaks into the scene to be shot, thereby increasing the self-timer delay time and thereby improving the success rate of the camera self-timer, and is convenient to use. Take a selfie. [Embodiment] Referring to FIG. 1, a frame diagram of a camera 100 according to a preferred embodiment of the present invention includes a lens unit 110, a sensing unit 120, an image processing unit 130, a self-timer unit 140, and a storage unit 160. The lens unit 110 is configured to focus and image the image to be captured by the one or more sets of lenses on the sensing unit 120. The sensing unit 120 is configured to sense a to-be-captured image that is focused by the lens unit 110 and projected on the sensing unit 120, and convert the image to be captured into an image signal and transmit the image signal to the image processing unit. 130. The image processing unit 130 is configured to process the image signal sensed by the sensing unit 120, and store the processed image signal output or stored in the storage unit 160. The self-timer unit 140 is configured to perform image self-photographing and image storage in cooperation with the lens unit 110, the sensing unit 120, the image processing unit 130, and the storage unit 160 during shooting. The self-timer unit 140 includes a delay module 142, an image acquisition module 144, a motion detection module 146, a determination module 148, and an add-on module 150. The delay module 142 is configured to provide a self-timer delay, that is, a self-timer countdown when the self-timer function is turned on. When the self-timer delay is over, the camera will be activated to take a picture. The image acquisition module 144 is configured to continuously acquire image signals processed by the image processing unit 130, thereby obtaining image signals of different times and transmitting the acquired image signals to the motion detection. The mobile debt measurement analysis is performed in the module 146. The motion detection module 146 is configured to analyze, by the image acquisition module 144, the image signal acquired by the image acquisition module 144 during the self-timer delay to determine whether there is a continuously moving object into the scene to be captured. The detection method of the motion detection module 146 may be based on the Triple Frames Different And (TFDA) and the black and white image method for moving determination, but is not limited to using the motion detection. Test method. Referring to FIG. 3, the three-frame difference method and the black-and-white image motion detection method specifically include that three consecutive images are acquired by the image acquisition module 144, and the motion detection module 146 is to be The three images acquired by the image acquisition module 144 are analyzed. Assuming that the moving object forms a black matrix in the acquired image, the image acquisition module 144 acquires three consecutive images 200939745 in different time periods. Fi-ί, Fi, Fi+1, the motion detection module ΐ46 firstly performs the difference between the images Fi-1, Fi, and F1+l, and obtains two images each. The difference between the block images DM and Di, and then the obtained difference block images Di-l, Di are added to obtain the last moving block image Ai-Ι' by the moving block image Comparing the size of the area with the size of the area occupied by the first image, the moving track and the moving speed of the moving object can be obtained, and the time for the moving object to move out of the image area to be taken can be estimated based on the basis. And delaying by the time-added module ί50 Group 142 together with the corresponding value of the estimated time. Please refer to FIG. 4 as an analog diagram of the motion detection module 146 for detecting a stationary object. As can be seen from the figure, when the three-frame difference set method and the black-and-white image motion detection are performed on the stationary object, the final result is obtained. The image of the moving block is blank, that is, no moving object appears in the scene to be photographed. The determining module 148 is configured to determine whether the time delayed by the delay module 142 φ exceeds the tolerable time when the motion detecting module 146 detects that a moving object appears in the scene to be shot, that is, Whether a predetermined time value has been exceeded, the predetermined time value is pre-stored in the determination module 148. The judging module 148 is used for scenes with a large number of people, and when a person is constantly entering the scene to be photographed, when the delay time reaches a predetermined time value, such as 30s, the camera is no longer moved (four) and photographed. Therefore, it is used to prevent the adverse effects that cannot be performed by the scenes in which a large number of people flow. The time-adding module 150 is configured to: when the motion detecting module Ms detects that a moving object appears in the scene to be photographed, according to the time estimated by the motion detection 11 200939745 module 146 The delay time in the delay module 142. The value is added to the time value. It can be understood that the time-adding module 150 can also detect that a moving object appears in the scene to be shot. A predetermined time value is added to the delay module 142. The storage unit 160 is configured to store an image captured by the camera 100 and the predetermined time value. In the present invention, the motion detection module 146 is added to the self-timer unit 140 of the camera 100 to detect whether a moving object has entered the scene to be photographed during the self-timer, thereby increasing the delay time of the self-timer and effectively Improve the success rate of self-timer and get a satisfactory self-portrait image. Referring to FIG. 5, a method for self-timering using the camera 100 includes the following steps: S210, starting a self-timer function of the camera 100, and entering a self-timer delay state, that is, entering a self-timer countdown state; S220, acquiring the lens unit by the lens unit 110 and the sensing unit 120 image and β consecutive image signals processed by the image processing unit at different times; S230, performing motion detection analysis on the acquired continuous image signals to determine whether a moving object breaks into the scene to be photographed; S240 If no moving object breaks into the scene to be photographed, it is determined whether the self-timer delay ends; S250, if the self-timer delay ends, the camera 100 performs the photographing action, and stores the captured image; if the self-timer delay has not ended, the process returns to step S220 to continue. The detection of the moving image; S260, if a moving object enters the scene to be photographed, the time value of the delay time 12 200939745 is increased by a predetermined time length; S270, a delay is added to the delay time value of the delay module After 'determine whether the self-timer delay exceeds the predetermined tolerance:: the value of '1' then returns to step S22〇 to continue _ Moving images, if more than two of the pre Cloth tolerable time value of s step to store the image storage unit 160 is executed.
