Embodiment Construction
[0018] The mobile camera device of the present invention can be electronic products with camera functions such as digital cameras, video cameras or mobile phones.
[0019] see figure 1 The camera anti-shake device 10 of this embodiment has an image acquisition module 11, a coordinate calculation module 12, an image transformation module 14, and a Gaussian blur processing module 15, and the camera anti-shake device 10 also receives data input from an external gyroscope sensor 13.
[0020] The image acquisition module 11 is used to acquire images, and acquires images when the shutter of the mobile camera device is pressed or lifted. Of course, the image acquisition module 11 can also acquire images at any moment between the shutter is pressed and lifted, and the acquired The number of images can be increased.
[0021] The coordinate calculation module 12 receives the coordinate data input by the gyro sensor 13. In this embodiment, the gyro sensor 13 is an external device, that ...

The invention provides an anti-shake device and a method for photography. The device comprises an image capturing module, a coordinate calculation module, an image transformation module, and a Gaussian blur processing module, wherein the image capturing module is used for capturing images at a first moment to form first image data and images at a second moment to form second image data; the coordinate calculation module is used for recoding first coordinate data of a gyroscope sensor at the first moment and second coordinate data of the gyroscope sensor at the second moment, and calculating offset of the second coordinate data relative to the first coordinate data to form offset coordinate data; the image transformation module is used for performing perspective transformation processing to the corresponding second image data by utilizing the offset coordinate data to generate third image data of the second image data under the first image data; and the Gaussian blur processing module is used for performing Gaussian blur processing to the first image data and the third image data to generate effect image data. The method utilizes the anti-shake device to capture and process the images. The production cost of the anti-shake device for the photography can be reduced, and the quality and the efficiency of anti-shake processing of the images can be improved.
Description
technical field [0001] The invention relates to the field of mobile camera equipment, in particular to a camera anti-shake device and a camera anti-shake method provided in the mobile camera equipment. Background technique [0002] Most of the existing mobile camera equipment is equipped with an anti-shake device, so as to avoid blurred images caused by the photographer shaking when taking pictures. There are many kinds of anti-shake methods used in existing anti-shake devices and mobile camera equipment, some are implemented by optimizing the hardware of the mobile camera equipment, and others need to be implemented by software. [0003] Some existing anti-shake devices have a chip installed in the camera of the photographic equipment, and an image acquisition module is arranged in the chip. When the shutter is pressed, multiple images are continuously acquired to form multiple image data, usually four images are required. Or five images, and then process the obtained imag...
