What’s a mirrorless camera and what makes it different from a DSLR?

As the name suggests, a mirrorless camera is one that doesn’t require a reflex mirror, a key component of DSLR cameras. The mirror in a DSLR reflects the light up to the optical viewfinder. In a mirrorless camera, there is no optical viewfinder. Instead, the imaging sensor is exposed to light...

What is DOF?

In optics, particularly as it relates to film and photography, the optical phenomenon known as depth of field (DOF), is the distance about the plane of focus (POF) where objects appear acceptably sharp in an image. Although an optical imaging system can precisely focus on only one plane at a time, the decrease in...

Gesture & Non-Gesture ToF Applications

Generally speaking, 3D Time of Flight uses can be categorized into Gesture and Non-Gesture. The Gesture applications emphasize human interactions and speed; while non-gesture applications emphasize measurement accuracy. Gesture applications translate human movements (faces, hands, fingers or whole-body) into symbolic directives to command gaming consoles, smart televisions, or portable computing...
