Abstract: The invention provides an electronic device and a gain calibration method for an image stabilization function thereof. The method includes the following. The image stabilization function is activated. A first image is generated by using a first gain through an image capturing device, and a first blur degree of the first image is obtained. A second image is generated by using a second gain through the image capturing device, and a second blur degree of the second image is obtained. A reference blur degree corresponding to the second gain is determined according to the second blur degree. A calibrated gain for the image stabilization function is determined according to a linear relationship established between the first blur degree corresponding to the first gain and the reference blur degree corresponding to the second gain.

Abstract: An electronic device with a flash function and a driving method of a flash are provided. The electronic device includes a flash, an image sensor, and a processor. The flash has a red light source, a green light source, and a blue light source. The image sensor is configured to obtain a preview image of a current scene and outputting the raw data of the preview image. The processor obtains a red ratio value and a blue ratio value according to the current scene, and the processor determines the green brightness value, red brightness value and blue brightness value according to the red ratio value, the blue ratio value and an exposure sensitivity for obtaining the preview image. The processor drives the flash according to the calculated red brightness value, the calculated green brightness value, and the calculated blue brightness value.

Abstract: An image stabilization method and an electronic device. The image stabilization method is adapted for the electronic device including a camera module, and the method includes the following steps. Multiple continuous images are captured through the camera module. Feature point extraction is performed on a reference image among the continuous images, and multiple reference feature points of the reference image are obtained. Feature point tracking is performed on a first image among the continuous images based on the reference feature points, so as to obtain multiple first feature points of the first image. A space transformation matrix between the reference image and the first image is obtained according to the reference feature points and the first feature points. The first image is corrected according to the space transformation matrix, and a field-of-view stabilized image is obtained.
