1″ CMOS Sensor
The CR-N500 features a Canon 1″ 4K CMOS image sensor capable of UHD 4K video capture at 30p and up to 60p in Full HD, making the CR-N500 PTZ camera great for the remote and unobtrusive capture of professional productions.
The 1″ sensor allows for larger photosites compared to smaller-sized sensors found in other PTZ cameras, resulting in stunning images with less noise in low-light situations. The large sensor also exhibits a shallow depth of field at large apertures, producing blurred backgrounds in images, while Canon’s DPAF tracks and keeps subjects in sharp focus. The CR-N500’s DIG!C DV 6 imaging processor drives the high sensitivity (1.5 lux) and low-noise performance of the camera yielding amazing imagery in a variety of shooting conditions.
Canon DIG!C DV6 Processor
The CR-N500 PTZ camera incorporates Canon’s DIG!C DV 6 Image Processor, which is essential in providing high image quality, advanced performance, and convenient operability. This advanced core technology component provides the image-processing power and speed that enables features such as 4K UHD video acquisition and precise Hybrid AF.
Dual-Pixel CMOS AF
Dual-Pixel CMOS AF is Canon’s breakthrough AF technology that uses a CMOS sensor with a structure that combines imaging and phase-difference AF functions. The Dual-Pixel CMOS AF determines the focusing position by the phase difference, which drives the focusing lens smoothly and enables quick focusing. The AF tracking capability is effective even during zooming, panning, or tilting. On the other hand, with conventional contrast AF method, used by other cameras, the focusing position is determined by the contrast (difference of brightness). Therefore, the focusing lens may move slightly back and forth around the focusing position, which could cause delay when focusing.
Dual-Pixel Focus Guide
Utilizing information from Dual-Pixel CMOS AF, Dual-Pixel Focus Guide helps achieve precise focus by displaying focus assist information on the screen. It employs a truly and innovative user interface that helps enable the user to see if they are focused in front of or behind the subject through visual observation, and allows quick and accurate manual focus to be achieved. This helps simplify the focusing process when shooting in 4K UHD, which requires strict focus accuracy.
Face Detection and Tracking
The CR-N500 has multiple focus modes that aid the operator when confirming focus. When set to on, the Face Detection and Tracking can track the face of a subject when they are within a frame. Furthermore, there are two Face Detection options (Face Priority and Face Only). Face Priority will track a face within the scene; when a face is no longer within the scene, the camera will continue to focus within the predefined focus area. In the same way, the Face Only function will track the detected face within the scene; if the face is no longer within the scene, the camera will maintain its focus position without tracking for new objects. If more than one face is detected within a scene, the operator can toggle between detected faces. Both modes are useful when following a subject, allowing the operator to focus on composition while the camera handles focus.
