What can be used to enhance image resolution in digital imaging systems?

Using smaller pixel sizes can enhance image resolution in digital imaging systems because image resolution is directly tied to the number of pixels used to create an image. When pixels are smaller, more of them can fit into a given area, allowing for finer details to be captured and represented in the image. This increased pixel density results in better image sharpness and clarity, as each pixel can represent a more precise sample of the scene being imaged.

In contrast, reducing the matrix size or increasing pixel size would result in fewer pixels covering a given area. This would inherently lower the amount of detail captured, as larger pixels mean that each pixel has to average a larger area of the image, which can lead to loss of fine details and overall image quality. While utilizing advanced compression algorithms can help manage file sizes and storage usage, it does not directly enhance the resolution of the image itself. Therefore, employing smaller pixel sizes is the most effective way to improve image resolution in digital imaging systems.
