The 8th Generation DSP Chip From Samsung

Experience the most naturally beautiful images with the 8th generation

DSP chip from Samsung. Advanced Color Expression, Hyper Digital

Image Stabilizer, Super LCD plus, and Face Detection Auto Focus

combine to make your digital image dreams a reality.

Longer battery life, extended recording time, and higher quality digital

imaging are enabled by the SC-MX25/MX20’s Samsung chip. By

designing and implementing a powerful single chip control system,

power consumption is dramatically reduced, allowing you to capture

more memories that can be treasured for the rest of your life.

3D Motion Optimizer

3D Motion Optimizer Processing creates clearer, cleaner images. Unlike

conventional 2D processing, 3D processing compares previous and

following frames, divides the current frame into pixel blocks, detects

noise occurrence, and eliminates it efficiently without filtering the entire

image.

3D Noise Reduction

The SC-MX25/MX20 transcends the boundaries of convention by

introducing 3D noise reduction that dramatically eliminates noise whilst

maintaining the original edge and pattern of the image. By analyzing

motion between the frames, the frames are split into pattern/edge

frames and differential frames and are passed through separate filters

which maintain the pattern and edge and remove noise. After filtering,

the frames are combined once more to make a cleaner, clearer image.

Color as vivid as your memories

Digital Natural Color Processing creates an expanded palette of colors that

are closer to those seen in nature. By internally adjusting images beyond

RGB into 4 color CMYG spectral color matching, the SC-MX25/MX20 is

able to accurately recreate colors that are closer to those your eyes see,

closer to your memories, and closer to reality.
