There doesn't appear to be any moire in the image itself. What you are seeing are scaling errors when the image is resized by a particular application for display on a particular size screen or print. To solve this you can create, optimize, and export different resolutions of the image for different display environments. For instance the display on a ...


If you are noticing this while you are photographing, the easiest fix is to move forward or back, or zoom in or out. Changing the magnification of the subject will change how the pattern interacts with the sensor. If you're dealing with it after the fact, the previous answer regarding the moire brush is your best bet.


I'm not familiar with your exact camera, but I have done some image processing using Matlab in the past. It sounds like what you're seeing is the raw image, pre-demosaicing. The reason it looks green is that bayer pattern sensors have twice as many green pixels as red and blue ones. If I'm right, each pixel in your image will have a value of 0 in two out of ...


This is known as Moire and generally occurs in patterns outside of nature. When the fine patterns in the image intersect with the camera sensor, these moire effects occur. If you are using Lightroom, then it is very easily corrected. Open your image in Lightroom and go to the Developer Module Then click on the Adjustment brush. When the sliders for the ...


"I am not able to interpret the three matrices of dimensions 1280x720" -- Because they are four, Red, Green, Blue, Green, and if I remember correctly they use Aptina MT9M021 sensor, 1280 x 960. Dimensions of each matrix is half by half of the dimensions of the sensor, 640 x 480. "If I display the image in MATLAB it looks green if I use the imshow command." ...


Deconvolution can in principle allow you to reverse the unsharpness, but this works best when you have low noise images and you can extract the so-called point spread function accurately. Your camera settings caused a blur because a point in the scene affects not just one pixel but a group of pixels. The profile of the gray values is called the point spread ...


The best method to fix images that are out of focus is to go back and take the image again being more careful to properly focus. You can not accurately reproduce information that was never captured. Sharpening and deconvolution create artifacts that attempt to mimic information that was not recorded. The further out of focus the original image is, and the ...
