RGB-IR cameras are like having two special eyes that can see both color and invisible light at the same time.
Imagine you’re playing hide-and-seek in a room with bright lights on, that’s like color (which we call RGB). Now imagine someone turns off the lights, but you still see your friend hiding behind the couch, that’s like invisible light, or IR (short for infrared).
How it works
RGB stands for red, green, and blue, the three basic colors of light. When these mix together, they make all the colors we see every day.
IR is a type of light that we can’t see with our eyes, but some cameras can catch it. It’s like when you use a nightlight to read a book, the light helps you see even in the dark.
RGB-IR cameras have two special lenses (or sometimes one lens that switches between them) so they can take pictures using both color and invisible light at the same time. This is super useful for things like security cameras, where they need to work well both during the day and at night!
Examples
- Imagine a night vision camera that also shows colors, not just black and white.
- RGB-IR cameras are used in drones to help them see both day and night.
