Multiple Formats from a Single Sensor
The AltaChrome A4590-4T provides a versatile sensor architecture that allows one multiformat camera to replace several single-format cameras. The sensor can be dynamically programmed to change resolutions and frame rates, and sensor operations in each of the formats can be fine-tuned to provide optimal image quality. Sensor operation is also compatible with SMPTE standards, assuring artifact-free video.
Highest Speed at True HD Resolution
At full 1080 resolution, the AltaChrome A4590-4T scans in progressive format up to a true 90 fps to produce high-speed video devoid of any artifacts.
Broadcast-Grade Slave Timing
Slave sensor controls and timing enable broadcast-grade synchronization with one or more additional A4590-4T sensors, for 3D or other multi-sensor applications.
Superior iSoC Image Processing
The AltaChrome A4590-4T automatically suppresses noise in all imaging modes, while minimizing camera complexity and cost. The AltaChrome A4590-4T 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.
To order the AltaChrome A4590-4T, use the part number A4590.
