Image Engineering introduce the new high resolution test charts for cameras with up to 180 megapixels. Of course these charts also fit perfectly for the upcoming 4k and 8k needs in broadcast and cinematography cameras.
A new worldwide unique high resolution printer enables Image Engineering to provide test charts for testing cameras with a pixel count of up to 180 megapixels using a standard A1066 (124,5 x 83,5 cm) sized test chart. Prior to this improved technical development, the maximum pixel count for cameras tested with conventional targets was 30 megapixels. The new printing technology uses photographic paper and is able to print continuous tone structures. In comparison, a standard ink jet printing process uses several ink dots to form the right colors and therefore produces a much lower resolution.
TE253
Beside the extrem high resolution, the chart is now less sensitive to scratches and abrasion compared to the previous versions. Due to the fact that the image is printed on silver halide material that is spectrally neutral even in the infrared region, it is also suited for use with IR cameras. The only little drawback: The surface of the new material is not as matt as the one of the old material and therefore requires a little more care in terms of adjusting illumination to avoid specular reflections.
TE268 (aspect ratio 3:2 and 4:3 possible) is only offered with 144 cycles in sizes
The first two chart types that are produced with the new process are the resolution charts TE253 and the TE268 with sinusoidal Siemens stars for resolution measurements as described in the upcoming revision of ISO 12233.
