A large matrix with small pixel will give a better resolution.
small pixels
No, a scanning process will result in a LARGE number of pixels not a "small number" of pixels as suggested in your question. Also images are frequently captured/stored in a compressed format (to reduce the file size), in which case there will not be a one to one match between the pixels detected by the scanning process and the stored image.
Unless you want to make still photos as well, it does not matter. See Canon vixia HF M52. Small sensor (1/3), small number of pixels = small pixel density = less noise = better picture quality. But it is not always the rule. Sometimes more pixels mean more data for image processing = better noise reduction = better image.
small
Mega pixels to you a picture tells how big it is. digital photos of small points in the name of pixels and each of these pixels can immediately different color and Light.
Small bacause if you have large you could hear things you are not supposed to
they are better and reproduces faster
The tiny dots that are visible on photo images are called pixels. There are generally thousands of pixels in a small area of a photograph. The larger the number of pixels in a small area, the clearer the photograph appears.
According to CNET the best compact digital camera are the new sleek small cameras that have touch screen built in the camera. Also, the camera's will better pixels and the higher the pixels the clearer the images will be.
Big as a breadbox
Each "pixel" is a part of the image that remembers a very small part of the digital picture. It is due to the huge number of pixels (megapixel = 1,000,000 pixels) that your digital images retain so much detail. Just remember, the more megapixels, the more detail... but it doesn't necessarily mean a better photo!
Quite the opposite actually, the more pixels there are is generally the higher resolution
