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 sharpness is gradual on each side of the POF, so that within the DOF the unsharpness is imperceptible under normal viewing conditions. In some cases, it may be desirable to have [...]

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 devices. For example, channel surfing can be accomplished by waving of hands and presentations can be scrolled by using finger flickering. These applications usually require fast response time, low- to medium-range, [...]

Sony Boosts 3D Camera Output After Interest From Phone Makers

Sony Corp., the biggest maker of camera chips used in smartphones, is boosting production of next-generation 3D sensors after getting interest from customers including Apple Inc. The chips will power front- and rear-facing 3D cameras of models from several smartphone makers in 2019, with Sony kicking off mass production in late summer to meet demand, according to Satoshi Yoshihara, head of Sony’s sensor division. He declined to provide sales or production targets, but said the 3D business is already operating profitably [...]
