2/3-inch Optical Format, 2.38 MP (2048 x 1164) at 90p in Monochrome
Multiple Formats from a Single SensorThe 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 ResolutionAt 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. Non-scaled (windowed) 720p is available in window mode at 120 fps using a 1/2.3-inch optical format.
Broadcast-Grade Slave TimingSlave 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 ProcessingThe 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:
