3	(3) Low key saturation
	With conventional cameras, low light areas can be
	subject to a reduction in saturation. This can result in

color in these areas being "washed out". The Low Key Saturation function on the HDC-900 Series eliminates this problem by optimizing the amplification of color saturation at low light levels, providing more natural color reproduction.

(4)Adaptive highlight control (Auto Knee mode) Conventional cameras only have a single knee point/ slope characteristic. In contrast, the Sony ADSP system has multiple knee point/slope characteristics. The camera monitors the brightness of all areas of the picture and adapts the knee point/slope for optimum reproduction. A typical example is shooting an interior scene which includes a sunlit exterior seen through a window. This new function applies only to video levels in excess of the knee point, the middle and low luminance parts remaining unchanged.

(5) Triple Skin Tone Detail Correction

Skin Tone Detail Correction controls the detail level of those objects which have specific color tones. The HDC-900 Series allows detail to be set independently for each of three separate color ranges. Colors are not limited to skin tones, but can be set for any color. Detail may be increased or decreased relative to the normal level.

Phase: Sets the color phase for which Skin Tone Detail Correction is activated.

Width: Sets the color width for which Skin Tone Detail Correction is activated.
