Creative Image ControlKnee Saturation ControlTraditionally, shooting very bright portions ofan object (such as key light reflections from aperson's forehead) can often reduce coloursaturation and change the hue. The BVP-E30Series adopts a knee saturation control functionin which this 'wash-out' effect onsaturation and hue change is reduced to aminimum, providing a far more natural colourreproduction in areas of high light.Low Key SaturationWith conventional cameras, low-light areascan be subject to a reduction in saturation.This can result in the colour in these areasbeing “washed out”. The low key saturationfunction on the BVP-E30 Series eliminatesthis problem by optimising the amplification ofcolour saturation at low light levels, providingmore natural colour reproduction.Knee Saturation OffKnee Saturation OnLow Key Saturation OffLow Key Saturation OnAdaptive Highlight Control(Auto Knee Mode)In conventional cameras, only a single knee-point/slope isavailable for control over highlights. The BVP-E30 Series,however, provides multiple knee-points/slopes for superboverexposure control. The camera detects the highly-litareas of a scene and automatically sets and optimisesmultiple knee points/slopes accordingly. This allows thereproduction of extremely difficult images (such as aninterior scene with a brightly sunlit window) with muchmore overexposure latitude. This function applies onlyto input video levels in excess of the knee point; themiddle and low luminance parts of the video signal areunaffected.Multi-Matrix FunctionThe multi-matrix function of the BVP-E30 Series allows colouradjustments to be applied over the colour range specified bythe operator. The colour spectrum is divided into 16 areas ofadjustment, where the hue and/or saturation of each area canbe modified. This function is especially useful when only the hueof certain colours needs to be adjusted for special-effects work.Input signal levelWhite clipAuto slopeknee point nknee point 3knee point 2knee point 1knee point 0Output signal levelKnee Curve Image4
Enhanced Vertical Detail(Non-Additive Mix)In conventional cameras, vertical detail signals arecreated using the Y-channel, G-channel or, morecommonly, the R/G channels combined. Each methodhas its limitations, such as when the colour channelselected to create the detail signal is at a low level. TheBVP-E30 Series uses an adaptive image-enhancementmethod. This creates detail signals from each of theR/G/B components of the video signal, comparesthem, and then automatically selects the channel withthe highest contrast level for use as the detail signal(Non-Additive Mix). This avoids the conventionalrestrictions of image enhancement observed above.The BVP-E30 Series can automatically correct theenhanced vertical detail but, if required, operators maymanually select from the Y, G, or R/G image enhancementmodes.Enhanced Vertical Detail(Non-Additive Mix) OffEnhanced Vertical Detail(Non-Additive Mix) OnAdaptive Detail Control OffAdaptive Detail Control OnMulti-matrix OffMulti-matrix OnLow Light ShootingThe BVP-E30 Series offers two convenient functionsfor capturing clear images in low-light environments –a slow shutter mode and gain function – which canbe used separately or together. The slow shutter modeallows the charge accumulation period of the CCDto be extended to seven frames. The gain functionallows the camera gain to be boosted to +42 dB.When used together, the camera offers a minimumillumination of 0.035 lx.Adaptive Detail ControlThe adaptive detail control automatically optimises theamplitude of the detail signal for high-contrastpicture edges. It also eliminates digital aliasing effects,offering very “natural” image enhancement duringscenes in which there are severe changes in contrast.Triple Skin Tone Detail ControlThe BVP-E30 Series Skin Tone Detail function enablescontrol of image enhancement within user-specifiedcolour tones. The BVP-E30 Series allows enhancementto be set independently for up to three distinctcolour and/or hue ranges. Skin Tone Detail correctionis conventionally used to reduce the amount of detailcontrol in areas of skin tone. With the BVP-E30 Series,correction is not restricted to skin tone and can beapplied to any area of colour. Image enhancementwithin the three areas can be increased or decreasedrelative to the overall image enhancement of a givenscene.Electronic Soft FocusThe BVP-E30 Series' electronic soft focus appliesa similar effect to that of an optical soft-focus filter -but in a much more convenient way. Rather thanincreasing the level of the detail signal, this functionreduces it - providing a picture that is "softer" thanthat achieved when detail is switched off completely.Electronic soft focus is also effective when used inconjunction with skin-tone detail to only change thesharpness within a specific colour or hue range.5
