Moreover, with Q Series built-in High Dynamic Contrast Range (HDCR), image washout in high ambient light conditions is eliminated.
The system offers the highest resolution on the market, at 20 lp/mm (line-pairs per millimeter), as well as a very high contrast range of 4,096 shades of grey, enabling the detection of even the smallest micro-calcifications.
Also, the High Dynamic Contrast Range (HDCR) results in highly detailed images by adjusting the dynamic contrast level to rid images of excess ambient light on screen.
A high contrast, anti-reflective glass shield increases contrast range and creates a sharp picture rivaling more expensive HD panels.
While non-HDR cameras take pictures at one exposure level with limited contrast range, losing detail in bright or dark areas of a picture, HDR takes multiple pictures at different exposure levels and intelligently stitches them together.
Unlike conventional systems that take color information from the CCD and apply the same mid-tone contrast ranges (gamma) to both the color and luminance (brightness) signals, Olympus' Proper Gamma II technology separates the color and luminance signals and calculates the optimum gamma (mid-tone contrast range) while maintaining the correct black to white range for each type of signal.
