Problems solved by technology

But in this way, since the method is to reduce the image first (which will not affect the image quality) and then enlarge the image (which will make the image jagged and cause poor quality), users often complain that the interpolation point operation enlargement poor image quality

Embodiment Construction

[0043] Please refer to FIG. 1 , which is a system block diagram of a digital camera according to the present invention. As shown in FIG. 1 , the digital camera 1 of the present invention includes a digital signal processor (DSP) 3 and a memory 5 . The digital camera 1 of the present invention can enlarge an original image 10 captured by the interpolation point technique, for example, to the enlarged image 20 shown by the dotted line. The memory 5 includes a buffer B and an image data storage area D, wherein the original image 10 and the magnified image 20 are all stored in the image data storage area D.

[0044] The original image 10 captured by the digital camera 1 is stored in the memory 5 of the digital camera 1 , and the memory 5 can be a built-in SDRAM in the digital camera 1 . It should be noted here that the original image 10 referred to in the description of the present invention is not limited to the image captured by the digital camera 1 for the first time. in the ...

Abstract

The method includes steps: segmenting raw image into multiple segmentation zones (SZ); defining first SZ; based on sequence, defining second SZ adjacent to first SZ, third SZ... till last SZ; using interpolation point technique magnifies first SZ in a first specific multiplying factor, and then decreases it in a second specific multiplying factor in order to form first processed zone from the first SZ; using the interpolation point technique to process all SZ till last SZ in sequence according to the said processing procedure so as to obtain all processed zones. From first processed zone to last processed zone forms magnified image.

Description

technical field [0001] The present invention relates to a method for enlarging an image and a digital camera using the method, in particular to a method for enlarging an image by using interpolation point technology and its application in a digital camera. Background technique [0002] One of the most important components of a digital camera is a Charge Couple Device (CCD). The digital camera converts the optical signal into an electronic signal by the CCD, and then records it on the built-in memory (such as 32M or 16M SDRAM) in the digital camera to form an image. [0003] The most basic unit of an image is a pixel. Simply put, a pixel is a point that makes up an image. Therefore, the more pixels in an image, the clearer the image quality will be. [0004] For a 1,600×1,200 image graphic file, the graphic file actually has 1,920,000 pixels. In other words, it can also be said that this image graphic is composed of 1.92 million small dots. The maximum pixel unit of a digi...
