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.
An image is made up of pixels, or tiny squares that each have a designated color. the pixels are normally so small that you don't see them. However, sometimes a picture looks blurry when resized. That blurry image is a pixelated image.
I believe that you may be referring to pixels. Digital pictures are made up of (most of the time) thousands of pixels (depending on the resolution, e.g. there are more pixels in an 800x600 image than in a 640x420 image, given in length x width format). The more pixels an image has, the higher quality and the clearer the image is. Cameras are often rated by Megapixels. A Megapixel, judging from the name, is a block of 1,000,000 pixels. If a camera has 4 megapixels, then the image is essentially split into 4 parts, each containing 1,000,000 pixels for the obvious total of 4,000,000 pixels. However, if it is only 2 MP, then you have only half the pixels, and the image will be nowhere near as sharp. I hope this helped.
small pixels
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.
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

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.
There Is No One Answer to Pixels per Inch, However, pixels are different sizes on different displays, so the answer is 58.74 pixels per inch on a 75-inch 4K television, for example, but 440.58 pixels per inch on a 5"-inch full HD smartphone screen.
The arrangement of dots, or pixels, on a grid refers to the systematic organization of small square units that collectively form an image or display. Each pixel represents a specific color or intensity, and when combined, they create visual content on screens or in digital images. The grid's resolution, determined by the number of pixels along its width and height, impacts the clarity and detail of the image. This arrangement is fundamental in digital graphics, photography, and various display technologies.
A pixel is a small component of a larger image. Millions of pixels make up a digital image. For a throwback look, some like the look of "pixelated" art. Pixelated art is the opposite of a high definition digital display. Pixels are oversized and square. Some websites have software that allow you to make pixel art. Once such site is makepixelart.com.
A large matrix with small pixel will give a better resolution.
