2/3-inch Optical Format, 2.38 MP (2048 x 1164) at 90p in RGB

Unparalleled Low-Light Performance
The AltaChrome A4592-4T offers unparalleled low-light performance thanks to its 5-mm pixel pitch and AltaChrome low-noise technology. A first in the industry, the AltaChrome A4592-4T combines the optimal balance of cost, speed, and high-quality, low-light performance for demanding applications that require more precision than available with current CCD technology. This sensor is ideally suited for high-end videoconference and security cameras requiring enhanced low-light performance and dynamic range.

Highest Speed at True HD and Native 2K Resolution
At full 1080 and 2K resolution, the AltaChrome A4592-4T scans in progressive format up to a true 90 fps to produce high-speed video devoid of any artifacts. Sensor operation is compatible with multiple SMPTE standards, assuring artifact-free video. Native 2K resolution supports digital cinematography applications. Non-scaled (windowed) 720p is available in window mode at 120 fps using a 1/2.3-inch optical format.

Broadcast-Grade Slave Timing
Slave sensor controls and timing enable broadcast-grade synchronization with one or more additional A4592-4T sensors, for 3D or other multi-sensor applications.

Superior iSoC Image Processing  
The AltaChrome A4592-4T automatically suppresses noise in all imaging modes, while minimizing camera complexity and cost. The AltaChrome A4592-4T uses the industry's most advanced and deepest on-chip signal processing to generate 12-bit data or 14-bit data that fully captures the subtlest scene details. Additional features include the following:
  • Automatic Black Clamp for real-time calibration of black values in every frame.
  • Automatic Column Fixed Pattern Noise (FPN) Suppression to eliminate variation among individual columns.
  • Line Noise Suppression to remove instantaneous and systematic variation among pixel rows.
  • Dynamic Pixel Defect Correction to reduce the amount of system resource needed in the image signal processor (ISP).
  • Oversampling feature to boost sensor sensitivity.
