A method of image processing within a portable terminal comprising: operating an image signal processor, ISP; and operating an application processor, AP; wherein operating the ISP comprises: for each frame of a plurality of frames acquired by a camera upon shooting, acquiring a frame image from said frame; generating a display image and a compression image from the respective acquired frame image; and transmitting the display image and the compression image to the AP; wherein generating the compression images comprises: storing one frame image every N frame images as a reference image, compress-coding said reference image and outputting said compressed reference image as a corresponding compression image; comparing each of the remaining frame images other than said reference image to said reference image to detect a motion vector for the respective remaining frame image; if the motion vector is greater than or equal to a preset reference value, compress-coding the respective remaining frame image and outputting said compressed remaining frame image as a corresponding compression image; and if the motion vector is less than the preset reference value, compress-coding the motion vector and outputting said compressed motion vector as a corresponding compression image; and wherein operating the AP comprises: buffering the display images and the compression images received from the ISP; for each of the acquired frame images, displaying the corresponding display image and decompressing the corresponding compression image to form a decompressed image; compressing the decompressed images to form a compressed moving picture; and storing the compressed moving picture. operating an image signal processor, ISP; and operating an application processor, AP; wherein operating the ISP comprises: for each frame of a plurality of frames acquired by a camera upon shooting, acquiring a frame image from said frame; generating a display image and a compression image from the respective acquired frame image; and transmitting the display image and the compression image to the AP; for each frame of a plurality of frames acquired by a camera upon shooting, acquiring a frame image from said frame; generating a display image and a compression image from the respective acquired frame image; and transmitting the display image and the compression image to the AP; wherein generating the compression images comprises: storing one frame image every N frame images as a reference image, compress-coding said reference image and outputting said compressed reference image as a corresponding compression image; comparing each of the remaining frame images other than said reference image to said reference image to detect a motion vector for the respective remaining frame image; if the motion vector is greater than or equal to a preset reference value, compress-coding the respective remaining frame image and outputting said compressed remaining frame image as a corresponding compression image; and if the motion vector is less than the preset reference value, compress-coding the motion vector and outputting said compressed motion vector as a corresponding compression image; and storing one frame image every N frame images as a reference image, compress-coding said reference image and outputting said compressed reference image as a corresponding compression image; comparing each of the remaining frame images other than said reference image to said reference image to detect a motion vector for the respective remaining frame image; if the motion vector is greater than or equal to a preset reference value, compress-coding the respective remaining frame image and outputting said compressed remaining frame image as a corresponding compression image; and if the motion vector is less than the preset reference value, compress-coding the motion vector and outputting said compressed motion vector as a corresponding compression image; and wherein operating the AP comprises: buffering the display images and the compression images received from the ISP; for each of the acquired frame images, displaying the corresponding display image and decompressing the corresponding compression image to form a decompressed image; compressing the decompressed images to form a compressed moving picture; and storing the compressed moving picture. buffering the display images and the compression images received from the ISP; for each of the acquired frame images, displaying the corresponding display image and decompressing the corresponding compression image to form a decompressed image; compressing the decompressed images to form a compressed moving picture; and storing the compressed moving picture.
