An image capturing method including following steps is provided. A preview image is captured and compressed into a compressed preview image according to a preview quantization table. An image complexity is judged by determining the amount of high frequency components the preview image has according to a set of factors consisting of the preview quantization table, a resolution of the preview image and a size of the compressed preview image. The more the amount of high frequency components the preview image has, the higher the image complexity. A to-be-captured image is captured. An initial quantization table is determined according to a set of factors consisting of the image complexity, a resolution of the to-be-captured image and an image compression target. The to-be-captured image is compressed into an output image according to the initial quantization table.

Apparatus and method for image capturing

A method for obtaining a still image frame with anti-vibration clearness includes the following steps. Multiple raw image frames are captured during a capturing period according to a capturing instruction. The raw image frames are compressed respectively, according to a predetermined compression rule, into multiple compressed image frames each of which has a data length after such compression. The compressed image frames are stored according to a predetermined sequence. The data lengths of the compressed image frames stored are compared according to the predetermined sequence. The desired still image frame is obtained through the compressed image frame of which the data length has a unique feature among all the compressed image frames.
