MacBook Air camera horrible resolution and pixelated

Why is my MacBook camera pixelated?? I uses to have a MacBook Pro 2012, and change it or a MacBook Air2019, how is it posible that a 7 year old model has a better camera

I am completely disappointed as a customer, how can I fix it, I can't even download the Photo Booth app

even my iPod 2025 has a better resolution, how is this posible

Help me to solve this
