Introduction to Dynamic Range Test Card

The dynamic range test card is a must-have standard board test card for mobile phone engineers, chip engineers, testing engineers, and optical engineers to test the performance of mobile phones and digital cameras. It can test parameters such as dynamic range, noise, SNR, etc.

The SineImage dynamic range test card complies with the ISO15739 standard and is used to test the noise and dynamic range of imaging systems. The density specification is derived from the ISO14524 standard. It can even be used to test TTL automatic exposure cameras without manual exposure control devices.

12 blocks with different densities (from 1st black to 12th white) form a circle. Three other blocks of different densities are located in the middle for basic noise measurement. Six sets of tilted modulation rods are used for measuring high-frequency noise. The density of the modulation rod is equal to the density of the 6th and 7th order.

There is a gradient density bar underneath for detecting noise levels at different density levels.
