So, I’ve recently started to learn about Display technologies, and I’m having countless questions.
How are able to use 8-bit per channel displays and not run out of system memory?
There must some amount of compression right? Where can I download a true 24 bit image with 1 bit colour occupying 1 bit memory?
In: Technology
8 bit per channel means 3 bytes per pixel or 3 megabytes per 1024×1024 uncompressed image (or 6 megabytes per 1920×1080 fullscreen image) which isn’t that much. Bmp files usually store data like that (some lossless compression may be possible but not always used). Jpg/png/gif use compression, all video is even more compressed.
Also, there are HDR image formats such as .tiff which use even more bits per channel.
