Mengenal Contrast Ratio

Contrast ratio adalah besarnya perbandingan Contrast antara warna satu dengan yang lainnya, Semakin tinggi perbedaannya semakin gambar terlihat nyata ( kedalaman warna gambar akan membuat antara objek dan latar semakin jelas ) Contrast ratio
tinggi membuat warna semakin tebal , di banding contrast rendah warna akan terlihat tipis.

contoh: contrast ratio 4000:1 artinya bagian gambar yang paling terang akan memiliki rasio 4000 kali lebih terang dari bagian gambar yang paling gelap

Proyektor Home Theater biasanya mempunyai Contrast ratio sangat besar, ini dikarenakan Projector Home Theater dituntut untuk menghasilkan gambar yang benar – benar nyata dengan kedalaman warna yang sesuai dengan konten yang ditayangkan.

contrast ratio juga dipengaruhi oleh kondisi cahaya disekitarnya. Pada suatu ruangan yang ideal, ruangan tersebut mampu menyerap semua pantulan cahaya dari Proyektor Dan satu-satunya cahaya yang kita lihat di ruangan tersebut hanya berasal dari Proyektor. Dengan kondisi cahaya tersebut, contrast rasio dari gambar akan sama dengan contrast ratio yang di klaim suatu produsen merk Proyektor tersebut.
