Panasonic AK-HC3800 2/3-type 2.2-megapixel 3CCD HD Studio Camera
Panasonic AK-HC3800 is an HD studio camera equipped with three high-sensitivity, high-quality 2/3-type 2.2-megapixel CCDs, a high-precision 16 bit A/D image processing circuit, and the latest generation 38-bit Digital Signal Processor (DSP). Compact and lightweight at only 8 lbs, it offers chromatic aberration compensation (CAC), scene file settings, and a sophisticated implementation of Panasonic’s exclusive dynamic range stretch (DRS).
Panasonic AK-HC3800 achieves a high sensitivity of F11 at 59.94Hz (2,000 lx) and an S/N ratio of 60dB. High definition formats can be switched to allow worldwide use at 1080/59.94i and 1080/50i. Output of 720/59.94p video will also be supported via a pre-NAB no-charge firmware upgrade. The newly-developed 16-bit A/D and 38-bit DSP utilize Spatial Offset Technology, and an advanced single transfer system to provide a high resolution picture (1,100 lines) with less moir? and a vertical smear level less than -130dB.
The Panasonic HC3800’s DRS function simultaneously reduces blocked detail in shadow areas and blown highlights in scenes where extremely bright and dark objects coexist, and its CAC function can compensate for chromatic aberration at the lens periphery. The low-profile head and low main body design are ergonomically designed for comfortable operation and provide an unobstructed view to the camera operator’s right-hand side.
The Panasonic HC3800 is also equipped with a Film Rec Gamma function adapted from Panasonic’s renowned VariCam models, and a Scan Reverse function for cinema lens adaptors.
3CCD with High Sensitivity, Low Noise and Low Smear
The Panasonic AK-HC3800 2/3-type 2.2-megapixel 3CCD enables the standard sensitivity of F11 (2,000 lx/59.94 Hz) which is one of the highest sensitivity in this range of cameras. A high S/N ratio of 60 dB (at 59.94 Hz) produces high quality images with low noise and low smear.
Panasonic’s single-channel transfer system and spatial-offset processing technologies also improve signal modulation depth and reduce more.
New High-Performance DSP Provides 16 bit A/D, 38 bit Processing
HD images are digitized with 74 MHz sampling and 16 bit A/D conversion. Full 38 bit processing within the DSP produces highly detailed, high quality images.
50 Hz/59.94 Hz Switchable
HD recording is switchable between 1080/50i (50 Hz) and 1080/59.94i (59.94Hz) for worldwide production use.
Chromatic Aberration Compensation (CAC)
This exclusive technology sets up a conversation between lens and camera which allows for a highly sophisticated algorithm to be deployed that will automatically compensate the registration error that is caused mainly by lens chromatic aberration, and minimize the circumjacent blur.
* When a CAC-compatible lens is used.
Digital Extender (2x)
This function expands the image by 2x in the digital signal processing circuit, allowing powerful shooting even with a low-magnification lens. HD images retain their superior resolution even with zooming, and – unlike when a lens extender is used – brightness is not reduced.
