What happens if adjacent pixels in a CCD become so close together that the angular separation between them is smaller than the resolution limit of the telescope being used?

Question

If adjacent pixels become so close together that the separation between them is smaller than the resolution limit of the telescope being used, the electronic signals from these pixels will effectively blend together and represent a single signal that gives the average intensity of the two-pixel region. This will result in a decrease in the level of detail and resolution in the image.
