Ansi

EN: Ansi lumens

Fotografie

American National Standards Institute standard for measuring light output perceived by human eye, measurement of overall brightness of projector. Latter calculated by dividing square meter image into 9 equal rectangles, measuring lux (brightness) reading at center of each rectangle, averaging nine points. Lamp choice, other technology, affects light output, e.g. halogen lamp appears dimmer than other metal-halide even when two have same ANSI lumens rating.

Ansi contrast

American National Standards Institute standard. Ratio between white and black. Larger ratio means greater ability of projector to show subtle color details, tolerate room light. Uses pattern of 16 alternating black and white rectangles, with average light output from white rectangles divided by average light output of black rectangles equalling contrast ratio. In contrast to Full On/Off contrast which measures ratio of light output between all white image (full on) and all black (full off) image.
