However there must always be polarizing differences between groups of people: in case of ' old movements ', they were the poverty and wealth gaps.

In the case of RealD a circularly polarizing liquid crystal filter which can switch polarity many times per second is placed on front of the projector lens.

In case of a low-pass filter or baseband signal, the bandwidth is equal to its upper cutoff frequency.

The 3 dB bandwidth of an electronic filter or communication channel is the part of the system's frequency response that lies within 3 dB of the response at its peak, which in the passband filter case is typically at or near its center frequency, and in the lowpass filter is near 0 hertz.

In this case, the filter bandwidth corresponds to the passband width, which in this example is the 1dB-bandwidth.

The bilinear transform is a special case of a conformal mapping ( namely, the Möbius transformation ), often used to convert a transfer function of a linear, time-invariant ( LTI ) filter in the continuous-time domain ( often called an analog filter ) to a transfer function of a linear, shift-invariant filter in the discrete-time domain ( often called a digital filter although there are analog filters constructed with switched capacitors that are discrete-time filters ).

Companies that make products that selectively block Web sites do not refer to these products as censorware, and prefer terms such as " Internet filter " or " URL Filter "; in the specialized case of software specifically designed to allow parents to monitor and restrict the access of their children, " parental control software " is also used.

The impulse response h completely characterizes any linear time-invariant ( or shift-invariant in the discrete-time case ) filter.

The emulsion consists of silver halide grains suspended in a gelatin colloid ; in the case of color film, there are three layers of silver halide, which are mixed with color couplers and interlayers that filter specific light spectra.

In this case, the filter need not be mounted vertically.

Many car and engine manufacturers support extended drain intervals, but request extended drain interval certified oil used in that case ; and sometimes a special oil filter.

If the example filters were required to match the case of the attribute value, an extensible match filter must be used, for example,

# In this case, to better emulate the sound of a plucked string, we want the filter cutoff frequency to start in the mid-range and move low.

For instance, in the case of the Chebyshev filter it is usual to define the cutoff frequency as the point after the last peak in the frequency response at which the level has fallen to the design value of the passband ripple.

In the case of linear time-invariant FIR filters, the impulse response is exactly equal to the sequence of filter coefficients:

In the case of ADSL, the voice component is also separated at this step, either by a filter integrated in the DSLAM or by a specialized filtering equipment installed before it.

In this case, the insertion loss is positive and measures how much smaller the signal is after adding the filter.

In this case, the filter has a passband gain of-R < sub > 2 </ sub >/ R < sub > 1 </ sub > and has a corner frequency of

Hence, this case corresponds to a high-pass filter with a very narrow stop band.

Hence, this case corresponds to a high-pass filter with a very wide stop band.

Left side is unmodified, Right side is with a high-pass filter applied ( in this case, with a radius of 4. 9 )

* 2007: On September 16, 2007, hunter Rick Jacobs captured an image of a supposed Sasquatch by using an automatically triggered camera attached to a tree, prompting a spokesperson for the Pennsylvania Game Commission to say that it was likely an image of " a bear with a severe case of mange.

The two neighbors took the first ex-aequo prize of the Congress of Documentary Film in 1943, for the first French underwater film: Par dix-huit mètres de fond ( 18 meters deep ), made without breathing apparatus the previous year in the Embiez islands ( Var ) with Philippe Tailliez and Frédéric Dumas, using a depth-pressure-proof camera case developed by mechanical engineer Léon Vèche ( engineer of Arts and Métiers and the Naval College ).

In reality, the actor or actress sees only the camera and its operator in this case, not their own reflection.

In addition to the high degree of realism, ray tracing can simulate the effects of a camera due to depth of field and aperture shape ( in this case a hexagon ).

In motion picture terminology, the term tracking shot may refer to a shot in which the camera is mounted on a camera dolly, a wheeled platform that is pushed on rails while the picture is being taken ; in this case the shot is also known as a dolly shot or trucking shot.

Perloff, who has written at length about the necessity of poetic works responding to and taking advantage of contemporary computer technologies, has written of Viola as an example of how new technology — in his case, the video camera — can create entirely new aesthetic criteria and possibilities that did not exist in previous

This case is commonly encountered in photography, where objects being photographed are often far from the camera.

In every case these scammers never have a webcam so you can't verify that they are the one truly in the picture they have sent, and offers to send a camera to them by postal mail ( instead of money to buy it ) are met with hostility.

In that case, the relative focal-plane illuminance, however, would depend only on the f-number N, so it is less in the camera with the larger format, longer focal length, and higher f-number.

The term " cinematographer " has been a point of contention for some time now ; some professionals insist that it only applies when the director of photography and camera operator are the same person, although this is far from being uniformly the case.

* Care and protection: including camera case and cover, maintenance tools, and screen protector

This model leads to the simple geometric model that photographers use for computing the angle of view of a camera ; in this case, the angle of view depends only on the ratio of focal length to film size.

The system is used by Chicago's Office of Emergency Management in case of an emergency call: it detects the caller's location and instantly displays the real-time video feed of the nearest security camera to the operator, not requiring any user intervention.

In the case of photographic film cameras the calculation is simple ; the final magnification is the product of: the objective lens magnification, the camera optics magnification and the enlargement factor of the film print relative to the negative.

The imaging device ( e. g. camera ) can either be separate from the main image processing unit or combined with it in which case the combination is generally called a smart camera or smart sensor.

Zoom lenses are a special case wherein the focal length, and hence angle of view, of the lens can be altered mechanically without removing the lens from the camera.

In the Abu Dhabi case the station airs the picture of Iraqi fire from beneath of the camera.

The digital files are then extracted from the camera, and in return for keeping the camera, they are printed out or stored to CD ( or DVD in the case of the Video Camera ) for the customer.

In this case, the image needs to be reflected left-to-right, as the prism transmits the image formed on the camera's focusing screen, which is itself reflected by the reflex mirror in the camera body.

In this case the vector space is R < sup > 3 </ sup > with the camera entrance pupil at the origin and the projective space corresponds to the image points.
