The Histogram Indicator for brightness can be displayed on the LCD monitor and viewfinder, allowing operators to easily
evaluate the brightness of captured images.
A target window appears in the center of the screen and the brightness level is indicated by a vertical red line in the histogram. The zebra indicator level appears as a yellow vertical line in the histogram as reference for proper exposure.
When the focus position needs to be manually moved to pre-decided positions, you can put up to two markers (A and B) on a focus position indicator in the LCD/EVF as reference points. When the focus position becomes aligned with one of these markers, it will begin to flash. This allows you to keep your eye on the subject of your shot, without having to check the focus indicator on the lens.
The HVR-Z7U and HVR-S270U both have a built-in threedimensional gravity (3G) sensor, which detects the horizontal level of the camcorder and displays it via an indicator in the LCD/EVF. This digital leveler function makes it possible to obtain a horizontal level reading even when shooting without a tripod.
Six types of AE (Auto Exposure) can be selected to automatically adjust the exposure to the most suitable level.
The supplied ECM-XM1 microphone's S/N ratio is 78 dB, a sensitivity increase of 14 dB over its predecessor, the ECM-NV1*6.
*6 The ECM-NV1 is a supplied microphone with DSR-PD170, DSR-250, HVR-A1U and HVR-V1U.
50i recording mode is added with modification at Sony service center.
The following functions are added:
HDV1080i recording: 50i, 25p
DVCAM/DV recording: 50i
Please consult your local Sony service center for the cost of this modification.
Three ND filters (1/4, 1/16, 1/64)
The HVR-Z7U and HVR-S270U have three built-in ND (Neutral Density) filters, which help users to reduce light intensity under bright shooting conditions.
Negative gain settings of -6 and -3 dB have also been added to help reduce sensitivity under bright lighting conditions. When the iris needs to be opened to create a short depth of field, a suitable brightness can be achieved with this function.
The Smooth Gain function is a smooth transition gain system that avoids sudden brightness changes caused by manual gain-level adjustment. With this function, the brightness changes gradually when the gain-level position is switched and avoids any sudden, unwanted iris adjustment.
Smooth WB (White Balance)
The Smooth WB feature is a smooth transition white balance system that avoids unnatural sudden color temperature changes between preset white balance settings. For example, this function is useful when you move from an artificial, low-light environment inside a building, to bright natural sunlight outside.
Up to six different picture-quality settings, including gamma and color settings, can be registered in the memory as picture profiles. This labor-saving function allows operators to easily recall customized picture-quality settings for various shooting conditions. It is also useful for matching footage shot at different times or for
The picture-profile functions of the HVR-Z7U and HVR-S270U include enhanced versions from the HVR-Z1U or HVR-V1U, plus a selection of new functions.
Generally, the brightness of a video image increases as the color level becomes more vivid. In these new camcorders, the brightness and color level are processed independently so that more flexible tone – for instance, a dark image with a vivid color – is realized by 3D-LUT color processing.
Note: 3D-LUT = three-dimensional look-up table
The Color Correction function of the HVR-Z1U has been improved in the HVR-Z7U and HVR-S270U camcorders. Color Correction provides two functions for creative shooting. The Color Extraction function can retain up to two desired colors of monitored pictures in the screen, while making all other colors black and white. The advanced function allows users to select the color simply by pressing a button to memorize the center color of the captured image.
The Color Revision function can change the hue of only the color designated by the Color Extraction function. This function is good not only for creating impressive images, but also for blue- or green-screen shooting in order to normalize uneven color.
The color data is stored in each Picture Profile so that users can select the most suitable color setting for each shooting situation.
The WB (White Balance) Shift function allows users to create an impressive color or to adjust the color
temperature of the camcorder.
There are two WB Shift options to choose from:
.LB-CC type: adjusting the LB axis (color temperature) and CC filter effect
.R-B level type: adjusting the red and blue levels
This function allows users to change the sharpness of an object with a specific color, and is particularly good for making skin tones look more natural. The target color can be specified by controlling the Phase/Range/Saturation/Y Level/Y Range parameters or by pressing a button to specify the color of an object with a color picker. If the sharpness of the background object is decreased, the blur looks more natural.
