This new-generation HD camera is designed to support the 720P or 1080I format.
The 720P or 1080I video format can be selected using the menu settings. This model uses newly developed 2/3 CCDs with a
million pixels [1280 (H) 720 (V)]. By taking a fresh approach to the on-chip lens, CCD structure and processes, these new
CCDs embody dramatically improved sensitivity, smear and dynamic range specifications compared with conventional CCDs,
and they achieve a high performance which is on a par with that of SD. Furthermore, the moire in the band has been slashed by
offsetting the pixels by combining Panasonic’s unique horizontal line readout CCDs with high-accuracy signal processing.
The newly developed digital signal processing LSI which supports 12-bit A/D conversion and which is provided in the camera
head processes the gamma, knee, detail, matrix and other process signals and uses a new system for CCD defect correction
to achieve improved operability with a greater number of functions, high quality and high stability which only digital systems can
deliver. The 12-bit A/D converter yields a stable wide dynamic circuit with a high signal-to-noise ratio from the dark areas to the
highlights.
A newly developed casing is used to house the multi-format camera head to achieve a compact size and light weight. The
amount of heat generated has been significantly reduced by designing the new circuitry to consume less power and by adopting
an efficient heat dissipation design for the new casing.
SD signals (D1, VBS) can be output and RET images and PROMPT signals can be input by connecting the multi-format camera
to the CCU (AK-HCU931P, optional accessory).
In terms of controlling the camera’s functions, the ROP (AK-HRP931P) or MSU (AK-MSU930P), also available as an optional
accessory, can be connected to the CCU to control such analog functions as the camera head’s pedestal and iris and to control
such switches as the gain and output selector switches.
