The electric flash-lamp uses electric current to start flash powder burning, to provide a brief sudden burst of bright light. It was principally used for flash photography in the early 20th century but had other uses as well. Previously, photographers' flash powder, introduced in 1887 by Adolf Miethe and Johannes Gaedicke, had to be ignited manually, exposing the user to greater risk.

A lamp house storing a plurality of flash lamps and a chamber storing and holding a semiconductor wafer are fitted to each other in an openable / closable manner. The lamp house and the chamber are fixed to a closed state with male screws. In order to process a semiconductor wafer, a shutter plate is drawn out to open an irradiation window. In this state, the shutter plate shields a space located above the male screws so that the male screws cannot be detached for opening the lamp house and the chamber. In order to open the lamp house and the chamber, the shutter plate must be inserted for shielding the irradiation window while opening the space located above the male screws. Thus, a thermal processing apparatus capable of preventing the lamps from breaking during maintenance thereof is provided.

Optimized Performance and Performance for Red-Eye Filter Method and Apparatus
A digital camera has an integral flash and stores and displays a digital image. Under certain conditions, a flash photograph taken with the camera may result in a red-eye phenomenon due to a reflection within an eye of a subject of the photograph. A digital apparatus has a red-eye filter which analyzes the stored image for the red-eye phenomenon and modifies the stored image to eliminate the red-eye phenomenon by changing the red area to black. The modification of the image is enabled when a photograph is taken under conditions indicative of the red-eye phenomenon. The modification is subject to anti-falsing analysis which further examines the area around the red-eye area for indicia of the eye of the subject. The detection and correction can be optimized for performance and quality by operating on subsample versions of the image when appropriate.

System and Method pertaining to the modification and integration of an existing consumer digital camera, for example, with an optical imaging module to enable point and shoot fundus photography of the eye. The auto-focus macro capability of existing consumer cameras is adapted to photograph the retina over an extended diopter range, eliminating the need for manual diopter focus adjustment. The thru-the-lens (TTL) auto-exposure flash capability of existing consumer cameras is adapted to photograph the retina with automatic flash exposure eliminating the need for manual flash adjustment. The consumer camera imaging sensor and flash are modified to allow the camera sensor to perform both non-mydriatic focusing of the retina using infrared illumination and standard color flash photography of the retina without the need for additional imaging sensors or mechanical filters. These modifications and integration of existing consumer cameras for fundus photography of the eye significantly improve ease of manufacture and usability over existing fundus cameras.

The present invention generally describes apparatuses and methods used to perform an annealing process on desired regions of a substrate. In one embodiment, pulses of electromagnetic energy are delivered to a substrate using a flash lamp or laser apparatus. The pulses may be from about 1 nsec to about 10 msec long, and each pulse has less energy than that required to melt the substrate material. The interval between pulses is generally long enough to allow the energy imparted by each pulse to dissipate completely. Thus, each pulse completes a micro-anneal cycle. The pulses may be delivered to the entire substrate at once, or to portions of the substrate at a time. Further embodiments provide an apparatus for powering a radiation assembly, and apparatuses for detecting the effect of pulses on a substrate.

The susceptor formed with the recessed portion holds the semiconductor wafer in such a manner that an inner wall surface of the recessed portion supports a peripheral portion of the semiconductor wafer. As a result, a gap filled with a layer of gas is formed between the lower surface of the semiconductor wafer and the upper surface of the susceptor, to prevent a crack in the semiconductor wafer when the semiconductor wafer is exposed to a flash of light from the flash lamps.

Control of a flash unit in a digital camera
ActiveUS20030007088A1Television system detailsTelevision system scanning detailsSingle flashElectronic shutter
The invention is based on a method for controlling a flashlight in connection with a digital image sensor without a mechanical shutter, wherein the exposure of the image sensor is performed in sub-areas, such as pixel rows or columns, or in another order, by using a rolling electronic shutter or the like. Thus, the exposure of said sub-areas of the image sensor takes place at least partly at different times. According to the invention, during the time of exposure of one image, i.e. substantially all the sub-areas of the image sensor, several discrete, successive flashes of the flashlight are used to achieve even exposure of the image area, which the flashes are timed in such a way that each single flash is triggered at a point of time which is common to the integration or exposure time of as many successive sub-areas of the image sensor as possible. According to the invention, the successive light flashes are also timed in such a way that one and only one flash of the flashlight occurs during the integration or exposure time of each single sub-area. By the present invention, the significant advantage is attained that the invention minimizes the number of light flashes required for one image while it also secures that each sub-area of the sensor to be exposed at a different time is illuminated as evenly as possible.

A first flash heating is performed in which a lower flash lamp irradiates a back surface of a semiconductor wafer with flashes of light, so that heat conduction from the back surface to a surface of the semiconductor wafer raises the temperature of the surface from the room temperature to an intermediate temperature. Then, a second flash heating is performed in which an upper flash lamp irradiates the surface of the semiconductor wafer with flashes of light, to raise the temperature of the surface of the semiconductor wafer from the intermediate temperature to a target temperature. Since only the irradiation with flashes of light emitted from the lower flash lamp and the upper flash lamp is used to cause the semiconductor wafer having the room temperature to reach the target temperature, all heat treatments can be completed in an extremely short time of one second or less.

If the value of the flash ON / OFF setup information is ON, a three-dimensional animation in which a flash (104) on a three-dimensional model (71) emits light is created and displayed in accordance with three-dimensional model data. If, on the other hand, the value is OFF, a three-dimensional animation in which the flash (104) on the three-dimensional (71) model does not emit light is displayed.

A capacitor, a coil, a flash lamp, and a switching element such as an IGBT are connected in series. A controller outputs a pulse signal to the gate of the switching element. A waveform setter sets the waveform of the pulse signal, based on the contents of input from an input unit. With electrical charge accumulated in the capacitor, a pulse signal is output to the gate of the switching element so that the flash lamp emits light intermittently. A change in the waveform of the pulse signal applied to the switching element will change the waveform of current flowing through the flash lamp and, accordingly, the form of light emission, thereby resulting in a change in the temperature profile for a semiconductor wafer.
