HL-59 - Digital Processing Portable Broadcast Camera

Ikegami's digital processing camera for creative field and studio production applications. Digital processing ICs at the heart of the camera have been newly developed while retaining digital processing-specific multifunctionality. Internal circuits have been reexamined to meet the trends of the times, thereby boasting outstanding video performance. 16:9/4:3 switchable capability is implemented as an option to meet users' demand. Accessories available from the Unicam Series ensures exceptional operational flexibility. A digital processing camera, upgraded with all practical considerations in mind. That's the HL-59.
The HL-59 achieves gripping picture quality with a horizontal resolution of 900 lines, in addition to a high level of stability and reliability provided by digital processing circuitry. Introducing a high-performance digital processing camera that delivers both substantial improvements in video performance and flexibility to handle a full range of applications.

• Substantial Improvement in Video Quality
  Video processing circuitry has been brought under a high level of design scrutiny to develop the next generation of digital processing ICs.  Video processing circuits subsequent to the PRE KNEE process are accomplished digitally, thereby enhancing reliability and delivering consistently stable video quality.
• High S/N Ratio
  10-bit quantization is employed in order to avoid degradation in S/N for both the black and white levels of video.  A high S/N ratio of 63dB is achieved.  Digital implementation of video processing circuits such as Gamma, Detail, and Matrix, ensures a dramatic improvement in actual S/N under operational conditions.
• Low Power Consumption
  The newly developed ASIC reduces power consumption.
• High-Performance 520,000-pixel CCDs
  The HL-59 employs 520,000-pixel high-performance FIT CCDS, while retaining the benefits of digital processing.  It attains gripping picture quality with a horizontal resolution of 850 lines or greater. In addition, the HL-59W (option) employs high-performance CCD imaging sensors with an aspect ratio of 16:9, so that simple switchable operation can be done. It ensures stable, crisp pictures in 16:9 and 4:3 modes.

• Newly Developed 1. 5" VF

  The HL-59 comes standard with a newly developed high-performance 1.5" viewfinder. In addition to 600 lines of horizontal resolution, the VF permits simple adjustment for brightness, contrast, and peaking through the trimmers located on the front of the VF. Its sliding mechanism provides considerable maneuverability.  The entire VF can be moved horizontally.

• Rotary Encoder
  A rotary pulse encoder is added to the side panel. It facilitates various camera setups, including shutter speed setup, in a menu-driven manner.
• Switch Panel Reexamined
  For user-friendliness, the switch panel features a new design with improved ease of use over its HL-series predecessors.
• Gain Selection
  The master gain control can be preselected within a wide range:-3/0/+6/+12/+18/+30/+36dB.
• Shutter
  In addition to seven preset shutter modes, CVSS(Continuous Variable Shutter Speed) is available two ranges. The shutter speed can be continuously varied from 1/30.5 to 1/57.3, and for an extended range from 1/60.3 to 1/1748 of a second.
• New Super V
  In addition to the conventional vertical resolution, with a frame accumulation mode and a 1/60 second exposure time, the HL59 comes with a newly developed New Super V function.  Switching in four steps (LOW, MID, HIGH, SUPER), it allows vertical resolution from 400 to 480 TV lines to be obtained, while minimizing loss of sensitivity. In the conventional Super V mode, some subjects may suffer increased line flickers due to excessive vertical resolution, resulting in degradation of image quality.  The HL-59's four-step resolution selection avoids this disadvantage, so that an optimum resolution can be selected according to the subject and application.
• Electronic Horizontal Level Indicator(EHL)
  Any horizontal tilt is sensed and indicated by characters within the viewfinder so that horizontal leveling of the camera can be easily maintained in portable use.
• Personal Function Switch
  A switch on the front of the camera switch controls the following functions;
  IRIS+ CORR
  IRIS++ CORR
  HYPER GAIN(+36dB)
  AUTO KNEE
  SKIN DTL
  SOFT DTL
  BLK PRESS/STRETCH -7%,-5%,-3%,+3%,+5%,+7%,
