Front-facing camera with connector of LG Optimus L7 II. A front-facing camera, commonly known as a selfie camera, is a common feature of cameras, mobile phones, smartphones, tablets, laptops, and some handheld video game consoles.
A flipped image is a static or moving image that is generated by a mirror-reversal of an original across a horizontal axis, making the image upside-down. In contrast, a flopped image is mirrored across the vertical axis, as in a conventional mirror image .
In photography and graphic arts a flopped image is a static or moving image that is generated by a reversal of an original image across a vertical axis, as in a conventional mirror image. This is opposed to a flipped image , which means an image reversed across a horizontal axis.
Webcam; Wright camera; Zenith camera; Zoom-lens reflex camera; The term camera is also used, for devices producing images or image sequences from measurements of the physical world, or when the image formation cannot be described as photographic: Acoustic camera which makes sound visible in three dimensions; Gamma camera
The Museum of Illusions refers to this type of mirror as an "antigravity mirror" because as it rotates once around the line-of-sight axis, the reflected image rotates twice, appearing upside-down when the joint is horizontal. Another type of non-reversing mirror can be made by making the mirror concave (curved inward like a bowl).
A pentaprism. A perspective drawing showing a roof pentaprism commonly used in a single lens reflex camera (SLR). The image is flipped laterally by the prism. A pentaprism is a five-sided reflecting prism used to deviate a beam of light by a constant 90°, even if the entry beam is not at 90° to the prism.
These cameras had no separate viewfinder. The exact image (although upside-down and reversed left-right) was viewed on a ground glass installed either in a replaceable plateholder, or in a spring back where springs hold the ground glass at the focus plane until a photographic plateholder is slid in front of it. Spring backs usually had a flip ...
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis ().
