Problems solved by technology

[0006] It can be seen from the above that if a single photo has been shaken during the shooting process, the photo blur cannot be avoided, and the high-speed complementary metal oxide semiconductor image sensor will cause the picture to be distorted due to the rolling shutter effect, and cannot be remedied by cropping the angle of view alignment

Embodiment Construction

[0028] Please refer to figure 2 and image 3 , figure 2 It is a schematic diagram of a camera 20 according to an embodiment of the present invention, image 3 It is a schematic diagram of an image blur prevention process 30 for the camera 20 . Such as figure 2 and image 3 As shown, the camera 20 includes an image processing chip 200 and an image sensor 202, the image sensor 202 can be a high-speed complementary metal oxide semiconductor image sensor (CMOS image sensor) or a photosensitive coupling device image sensor (charge-coupled device, CCD ), the image processing chip 200 can be used to execute the image blur prevention process 30 to avoid image blur caused by hand shake, and the image blur prevention process 30 includes the following steps:

[0029] Step 300: start.

[0030] Step 302: Obtain a movement data MD of the camera 20 .

[0031] Step 304: According to the movement data MD, take a photo PIC only when the camera 20 is roughly stationary.

[0032] Step ...

Abstract

The invention discloses an image fuzzy prevention method and an image processing chip. The image fuzzy prevention method comprises steps of obtaining a mobile material of a camera and taking a picture when the camera is almost at rest according to the mobile material.

Description

technical field [0001] The present invention relates to a method for preventing image blurring and its image processing chip, in particular to a method for preventing image blurring which can detect movement data of a camera, so as to only take photos when the camera is roughly still to avoid image blurring caused by hand shake and the method thereof. Image processing chip. Background technique [0002] Generally speaking, in order to avoid image blur caused by hand shake when shooting with the camera, the known technology can use multiple high-speed continuous shooting to achieve the purpose of high dynamic range (High Dynamic Range, HDR) or night scene anti-shake, or to increase the sensitivity Exposure time can be shortened according to the speed (ISO) to avoid jitter in a single photo, and multiple photos can be combined to increase brightness, or an accelerator sensor or digital anti-shake information can be added to detect moving data and then cropped ) and align diff...
