Enhanced Vertical Detail

(Non-Additive Mix)

In conventional cameras, vertical detail signals are

created using the Y-channel, G-channel or, more

commonly, the R/G channels combined. Each method

has its limitations, such as when the colour channel

selected to create the detail signal is at a low level. The

BVP-E30 Series uses an adaptive image-enhancement

method. This creates detail signals from each of the

R/G/B components of the video signal, compares

them, and then automatically selects the channel with

Low Light Shooting

The BVP-E30 Series offers two convenient functions

for capturing clear images in low-light environments –

a slow shutter mode and gain function – which can

be used separately or together. The slow shutter mode

allows the charge accumulation period of the CCD

to be extended to seven frames. The gain function

allows the camera gain to be boosted to +42 dB.

When used together, the camera offers a minimum

illumination of 0.035 lx.

Adaptive Detail Control

The adaptive detail control automatically optimises the

amplitude of the detail signal for high-contrast

picture edges. It also eliminates digital aliasing effects,

offering very "natural" image enhancement during

scenes in which there are severe changes in contrast.

the highest contrast level for use as the detail signal

(Non-Additive Mix). This avoids the conventional

restrictions of image enhancement observed above.

The BVP-E30 Series can automatically correct the

enhanced vertical detail but, if required, operators may

manually select from the Y, G, or R/G image enhance-

ment modes.

Triple Skin Tone Detail Control

The BVP-E30 Series Skin Tone Detail function enables

control of image enhancement within user-speciﬁed

colour tones. The BVP-E30 Series allows enhan-

cement to be set independently for up to three distinct

colour and/or hue ranges. Skin Tone Detail correction

is conventionally used to reduce the amount of detail

control in areas of skin tone. With the BVP-E30 Series,

correction is not restricted to skin tone and can be

applied to any area of colour. Image enhancement

within the three areas can be increased or decreased

relative to the overall image enhancement of a given

scene.

Electronic Soft Focus

The BVP-E30 Series' electronic soft focus applies

a similar effect to that of an optical soft-focus ﬁlter -

but in a much more convenient way. Rather than

increasing the level of the detail signal, this function

reduces it - providing a picture that is "softer" than

that achieved when detail is switched off completely.

Electronic soft focus is also effective when used in

conjunction with skin-tone detail to only change the

sharpness within a speciﬁc colour or hue range.
