Ccd Camcorder Definition?
A CCD camcorder contains a CCD (charge coupled device) image sensor. In a CCD image sensor, pixels capture light and move it toward the edge of the chip where it is converted into a digital signal.
How is a light box used in light therapy?
A photographic light box allows a photographer to capture an image clearer and more crisp. It also gives a solid color backdrop.
Is sensor an input or output device?
Assuming that a sensor (any type, heat, light, sound etc) is connected to something - eg a computer or a switch etc. it is an 'input' device. The device which created whatever is being 'sensed' is an output device. For example if you put a thermometer next to a light bulb to see how hot it is then the bulb is 'output' and the thermometer is 'input'.
What part of an image intensification tube converts the X-ray image into a visible image?
Input Phosphor. The x-ray image intensifier converts the transmitted x rays into a brightened, visible light image. Within an image intensifier, the input phosphor converts the x-ray photons to light photons, which are then converted to photoelectrons within the photocathode. The electrons are accelerated and focused by a series of electrodes striking the output phosphor, which converts the accelerated electrons into light photons that may be captured by various imaging devices.
Is a sensor an input or output device?
It is an input, sensors are always inputs.
Is a LED an input or output?
In Light Emitting Diodes when electron jumps from one state to another state it emits some energy in the form of light. And the light will be different for different type of semi conductor materials used for making for it. So, in conclusion Light in LED is a result of output process.
