How to adjust the pixel size of Fuji S4050 camera? And similar size, l; m； s； What does this mean? What does it have to do with pixels?

Adjust the image size to pixels equal to the image size, and pixels determine the image size. S: Shutter is preferred. After the shutter is set by the photographer, the aperture is set by the camera.

P: program exposure, similar to automatic shifting. The shutter and aperture are set by the camera, but they can be adjusted by themselves.

M: Manual exposure. The shutter aperture is set by the photographer himself.

L: It is the setting with the highest resolution in JPEG format in terms of image quality.

I suggest you shoot with the largest pixel, and the effect is better.
