Problems solved by technology

[0004] However, traditional digital cameras can only focus within a certain depth of field, and then shoot and expose the scene to be photographed. Therefore, only the scenes near the focused part can get clear images, while the scenes outside the focused part will become blurred. blurry
For example, when you want to take a picture of a child with a mountain as the background, you will focus on the child, so in the resulting photo, the child will be very clear, but the distant mountains will become quite blurred

Embodiment Construction

[0014] For the image synthesis method of the digital camera disclosed in the present invention, please refer to figure 2 , First, perform multiple exposures of the subject to be photographed (step 31). According to the depth of field, from near to far or from the center to the edge of the subject, focus sequentially for multiple exposures, obtain multiple images, and temporarily store them in a temporary storage. (Step 32), then extract the focused pixels from the image in the register (Step 33), combine the captured multiple focused pixels into an image file (Step 34), and then combine The synthesized image file is temporarily stored in another register (step 35).

[0015] For example, if you want to take a photo of a child with a distant mountain as the background (not shown in the figure), the digital camera will focus and expose the child first, and capture the child’s partially focused pixels into a register , And then focus on the distant mountains, then take out the pixels...

Abstract

The image synthesis method and synthesizer for digital camera may display different scenes of the same picture but in different field depths in different position in the picture clearly and simultaneously. By means of image synthesis, the scenes to be taken are multiple exposed and synthesized to form one image file, so that different scenes may be displayed clearly.

Description

Technical field [0001] The invention relates to an image synthesis method and device, especially an image synthesis method and device applied to a digital camera. Background technique [0002] Another name for a digital camera is "digital still camera" (DSC; Digital StillCamera) to distinguish it from a digital dynamic camera. A digital camera uses digital information to store the captured images. It uses a disk that can record images. Or PCMCIA (Personal Computer Memory Card International Association) and other memory cards to store static images. In order to save the storage space used by the storage media, the images taken by digital cameras are usually stored as compressed files. Commonly used are JPEG ( JointPhotographic Experts Group; Joint Photographic Experts Group) document format. [0003] Such as figure 1 As shown, the known digital camera uses the main central processing unit 18 to control all actions, and the user controls the digital camera through the user interfa...
