Flash Synchronization
In photography, flash synchronization or flash sync is the synchronizing the firing of a photographic flash with the opening of the shutter admitting light to photographic film or electronic image sensor. In cameras with mechanical (clockwork) shutters synchronization is supported by an electrical contact within the shutter mechanism, which closes the circuit at the appropriate moment in the shutter opening process. In electronic digital cameras, the mechanism is usually a programmable electronic timing circuit, which may, in some cameras, take input from a mechanical shutter contact. The flash is connected electrically to the camera either by a cable with a standardised coaxial PC (for Prontor/Compur) 3.5 mm (1/8") connector (as defined in ISO 519), or via contacts in an ''accessory mount'' (hot shoe) bracket. Faster shutter speeds are often better when there is significant ambient illumination, and flash is used to flash fill subjects that are backlit without motio ...

Interpolation
In the mathematical field of numerical analysis, interpolation is a type of estimation, a method of constructing (finding) new data points based on the range of a discrete set of known data points. In engineering and science, one often has a number of data points, obtained by sampling or experimentation, which represent the values of a function for a limited number of values of the independent variable. It is often required to interpolate; that is, estimate the value of that function for an intermediate value of the independent variable. A closely related problem is the approximation of a complicated function by a simple function. Suppose the formula for some given function is known, but too complicated to evaluate efficiently. A few data points from the original function can be interpolated to produce a simpler function which is still fairly close to the original. The resulting gain in simplicity may outweigh the loss from interpolation error and give better performance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Single-lens Reflex Camera
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either a prism, which shows the image in the viewfinder, or the image sensor when the shutter release button is pressed. The viewfinder of a DSLR presents an image that will not differ substantially from what is captured by the camera's sensor as it presents it as a direct optical view through the main camera lens, rather than showing an image through a separate secondary lens. DSLRs largely replaced film-based SLRs during the 2000s. Major camera manufacturers began to transition their product lines away from DSLR cameras to mirrorless interchangeable-lens cameras (MILC) beginning in the 2010 ...

Photodiodes
A photodiode is a light-sensitive semiconductor diode. It produces current when it absorbs photons. The package of a photodiode allows light (or infrared or ultraviolet radiation, or X-rays) to reach the sensitive part of the device. The package may include lenses or optical filters. Devices designed for use specially as a photodiode use a PIN junction rather than a p–n junction, to increase the speed of response. Photodiodes usually have a slower response time as their surface area increases. A photodiode is designed to operate in reverse bias. A solar cell used to generate electric solar power is a large area photodiode. Photodiodes are used in scientific and industrial instruments to measure light intensity, either for its own sake or as a measure of some other property (density of smoke, for example). A photodiode can be used as the receiver of data encoded on an infrared beam, as in household remote controls. Photodiodes can be used to form an optocoupler, allowing tran ...

FinePix S2 Pro
The Fujifilm FinePix S2 Pro is an interchangeable lens digital single-lens reflex camera introduced in January 2002. It is based on a Nikon F80 (N80 in the U.S.) film camera body that was modified by Fujifilm to include its own proprietary image sensor and electronics. Because of the Nikon body, it has a Nikon AF lens mount and so can use most lenses made for Nikon 35 mm cameras. It is autofocusing, with an electronically controlled focal plane shutter with speeds from 30 sec. to 1/4000 sec., built-in exposure metering and pop-up flash. Its ISO film speed equivalents range from 100 - 1600. The S2 Pro also has sound recording capability. The camera is no longer in production, having been superseded by the Fujifilm FinePix S3 Pro in February 2004. Aside from the Nikon lens mount, the camera's principal distinction is its 6.17 megapixel photo sensor. Known as the Super CCD, it is unique in having its photodiodes oriented diagonally rather than horizontally and vertically as in a ...

FinePix S1 Pro
The Fujifilm FinePix S1 Pro was an interchangeable lens digital single-lens reflex camera introduced in January 2000. It was based on a Nikon F60 (Nikon N60 in the U.S.) film camera body that was modified by Fujifilm to include its own proprietary image sensor and electronics. Because of the Nikon body, it had a Nikon F lens mount and so could use most lenses made for Nikon 35 mm format, 35 mm cameras. It was autofocusing, had an electronically controlled focal plane shutter with speeds from 30 sec. to 1/2000 sec. and built-in exposure metering and pop-up flash. Its International Organization for Standardization, ISO film speed equivalents ranged from 320-1600. The camera is no longer in production, having been superseded by the Fujifilm FinePix S2 Pro in January 2002. Aside from the Nikon lens mount, the camera's principal distinction was its unique (and controversial) 3.1 megapixel photo sensor.

Super CCD
Super CCD is a proprietary charge-coupled device that has been developed by Fujifilm since 1999. The Super CCD uses octagonal, rather than rectangular, pixels. This allows a higher horizontal and vertical resolution (at the expense of diagonal resolution) to be achieved than a traditional sensor of an equivalent pixel count. On January 21, 2003 Fujifilm announced the fourth generation of SuperCCD sensors, in two variations: SuperCCD HR and SuperCCD SR. HR stands for "high resolution" and SR stands for "super dynamic range". The SR sensor has two photodiodes per photosite, one much larger than the other. Appropriately processing information from both can yield larger black to white range of brightness (dynamic range). The 4th Generation Super CCD HR has sensors placed at 45 degrees to the horizontal. In order to convert the images into the normal horizontal/vertical pixel orientation, it interpolates one pixel between each pair of sensors, thereby producing 12 recorded megapixels ...

Focal Plane Shutter
In camera design, a focal-plane shutter (FPS) is a type of photographic shutter that is positioned immediately in front of the focal plane of the camera, that is, right in front of the photographic film or image sensor. Two-curtain shutters The traditional type of focal-plane shutter in 35 mm cameras, pioneered by Leitz for use in its Leica cameras, uses two shutter curtains, made of opaque rubberised fabric, that run horizontally across the film plane. For slower shutter speeds, the first curtain opens (usually) from right to left, and after the required time with the shutter open, the second curtain closes the aperture in the same direction. When the shutter is cocked again the shutter curtains are moved back to their starting positions, ready to be released. Focal-plane shutter at low speed ''Figure 1:'' The black rectangle represents the frame aperture through which the exposure is made. It is currently covered by the first shutter curtain, shown in red. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Single-lens Reflex Camera
A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system (hence "reflex" from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured.
