Chapter 1 General
1-1 Features of the camera unit
The AJ-HDX900 is a video camera-recorder that integrates an HD camera part equipped with a progressive scan (full pixel
reading) 3-CCD camera unit featuring a 2/3-inch on-chip lens with a VTR that in turn supports the DVCPRO HD EX format.
The progressive scan CCD produces high quality pictures with superior image expression.
The unit is both compact and lightweight, with minimal power consumption. Featuring high picture quality and sensitivity, the
camera-recorder has excellent mobility and effectively withstands dust, humidity, and moisture. With many other superior
functions, the unit is the optimum camera-recorder for production.
O Multi-format
The unit supports the following video systems by driving
the CCD progressively. (Refer to page 30)
O Storage type high-sensitivity function (DS. GAIN)
The unit uses the storage type gain increase function by
driving the CCD progressively. With this function, it is
possible to obtain brighter pictures without increasing
noise under low light conditions.
This is a function that makes it possible to achieve higher
sensitivity of up to 20 dB above the regular gain increase.
Furthermore, this function can also be used as picture
effects.
O 14-bit A/D conversion digital signal processing
Analog video signals are processed into digital data by a
14-bit A/D converter with sampling frequencies of 74 MHz.
It is possible to reproduce images that are more finely
detailed.
O Film-like Gamma function
The unit employs three types of film-like gamma to easily
obtain film tones accumulated through Varicam (AJ-
HDC27 series), so that a wide range of image impressions
can be reproduced for production. (Refer to page 113)
O Y-get function
By allocating functions to USER button, it is possible to
measure the subject’s video level easily. The lens
aperture can be adjusted precisely for appropriate
pictures. (Refer to page 62)
O Lens file function
The unit has 8 lens files.
By using an SD memory card, 64 lens files can be stored.
(Refer to page 74)
O Data management function
Within the unit, one user data file and four sets of scene
file data can be saved.
By using an SD memory card as the setup cart, up to
eight sets of setup data can be stored. (Refer to page 64)
O Color bar
The unit employs the SMPTE color bar, ARIB color bar,
Split color bar for SNG (Satellite News Gathering) as well
as the conventional color bar, which is useful for adjusting
the color monitor. (Refer to page 121)
O DRS (Dynamic Range Stretcher) function
The dynamic range can be streched by compressing the
video signal level of a part with high brightness where
white-color-skipping phenomena occur during ordinary
shooting. (Refer to page 62)
