[0039] figure 1 It is a block diagram of a digital video camera equipped with a moving image shake correction device in the first preferred embodiment of the present invention. Such as figure 1 As shown, the moving image shake correction device 100 in the first embodiment of the present invention is preferably provided in the digital image photographing device 1. The digital imaging device 1 may be a digital video camera, a digital camera with imaging function, a mobile terminal, or the like.
[0040] The moving image shake correction device 100 can interact with the image camera 10, the memory 20, the display 30, etc. of the digital image photography device 1. The image camera 10 is a device that captures images and converts them into electrical signals, such as a CMOS module, an optical camera sensor, and so on. The memory 20 is various storage mechanisms that can store digital data. In addition, the display 30 is a device that displays images on the screen, such as an LCD pa...
no. 2 Embodiment
[0112] Picture 10 It is a structural diagram illustrating a moving image shake correction device in a preferred second embodiment of the present invention. Such as Picture 10 As shown, the jitter correction device 101 in the preferred second embodiment of the present invention may further include the input processor 110, the selector 130, the arithmetic unit 140, the vector calculator 150, the output scaler 120, and the corrector described in the above content. 160 and controller 180.
[0113] The controller 180 calculates two frames respectively according to different pixels, for example, the difference value of the pixel values between the macroblocks at the same position contained in the previous frame and the current frame, and controls the pass calculation according to the calculation result. Statistical calculation performed by the processor. For example, the controller 180 respectively calculates the difference in pixel values between a specific macro block in the s...
no. 3 Embodiment
[0143] First of all, the preferred third embodiment of the present invention has the structure and structure of the moving image shake correction device Picture 10 The structure of the second embodiment shown is the same, and the function of the controller is modified. In the third embodiment, the controller calculates the difference value of each pixel value between the reference macro block of the previous frame and the macro block of the current frame, and calculates that the difference value in the reference macro block reaches the first reference value or The ratio of pixels above the reference value. Moreover, only when the calculated ratio reaches the second reference value or more, the arithmetic unit can be fully controlled.
[0144] Figure 13 It is a structural diagram of the controller of the moving image shake correction device in the preferred third embodiment of the present invention, Figure 14 Is description Figure 13 The flow chart of the controller action sho...
