Problems solved by technology

[0004] However, increasing the image processing speed will lead to the problem of insufficient bandwidth or the upper limit of the frequency in the use of the chip. Therefore, in the known technology, when performing digital amplification of high-magnification dynamic images, it is necessary to reduce the speed of dynamic images per second. The number of sheets to solve the problem caused by insufficient bandwidth
[0005] At the same time, in the known technology, the image processing system of a digital camera is a single-direction processing path, and each processing unit needs to have sufficient bandwidth capacity to store the data processed by the previous processing unit, so that it is easy to Insufficient bandwidth of the image processing program, resulting in noise and visual persistence

Abstract

The invention relates to a picture amplifying system of digit camera and relative method, which can selectively process low-zoom treatment or high-zoom treatment. And the method comprises that: reducing one picture data; processing amplifying pretreatment on the reduced picture, using said picture data as the picture data of said pretreatment; processing low-zoom treatment or high-zoom treatment.

Description

technical field [0001] The present invention relates to an image enlargement processing system and method of a digital camera, in particular to an image processing system and method of a digital camera with an enlargement pre-processing unit. Background technique [0002] Generally speaking, when digital cameras zoom in on dynamic or static images, the number of images displayed by the image display unit (such as LCD) per second must reach a certain number so as not to generate noise and visual persistence. This undoubtedly limits the image capture unit (such as CCD) to output each row of images to the image display unit within a certain period of time. [0003] Therefore, in the known technology, when performing image enlargement processing, the image processing unit must reserve a specific bandwidth to process the image to be enlarged, and the larger the magnification, the larger the bandwidth to be reserved, and When enlarging the dynamic image, the image processing unit...
