Digital Camera Lens Cover
- Usually captures images with the help of a CCD chip. The image data received is then saved to special memory cards or other storage media. (SmartMedia, xD-Picture Card, Compact Flash, Memory Stick, SD Card, MMC Card)
- A digital camera (also digicam or camera for short) is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor.
- A camera that records and stores digital images
- A lens cover or lens cap provides protection from scratches and minor collisions for camera and camcorder lenses. Lens covers come standard with most cameras and lenses. Some mobile camera phones include lens covers, such as the Sony Ericsson W800, the Sony Ericsson K750 and the Sony Ericsson K550.

Oscar discovering Digital Stroboscopic Motion photography
Stroboscopic photography for depicting the changing features of subjects in motion is a technique that was enabled and popularized by one of the "fathers" of high speed photography, Harold "Doc" Edgerton. He applied this technique to numerous situations where a still camera, in a single shot, did not capture enough information about a subject in motion and where a motion picture camera record was unsuitable for being reproduced on the printed page.
Photographers use two types of stroboscopes. The first, and most popualr, is nothing more than a flashing light source. This is the kind that Doc Edgerton popularized. There is also a chaper, simpler, mechanical alternative. This consists of nothing more complicated than a rotating disk with a slot cut into it it. With every rotation of the disc we are able to glimpse the position of the subject at the time the slot passes in front of our eyes.
In either case, a stroboscope allows us to view a subject on a periodic basis.
Photographers have generally used a flashing light, a stroboscopic light source, to illuminate a moving subject in order to track the subject position over time. This is accomplished by setting up an action situation if front of the camera generally firmly attached to a tripod, opening the shutter of the camera while the subject is moving and the stroboscope flashing and after a while closing the shutter and terminating the exposure.
During the time the shutter is open the moving subject is illuminated by several flashes of light. These leave a superimposed sequence of images of the subject and it is often possible to gain much valuable subject motion evaluation information from such a record or to simply connect with and understand the graceful (or not so graceful) flow of motion of a given subject.
When engaged in stroboscopic photography generally one is interested in photographing relatively long duration events (even though one may only be talking about a second or two!) because it is really pointless to to make a stroboscopic record while only recording the subejct in only one, two or three positions over time!
[stroboscopic photo made with Kodak DC260] [stroboscopic photo made with Kodak DC260] For example, to make a record of a golf swing or something similar, we would be looking to make a record over a time period of a second or so. During that time we might want to record our subject in maybe 20 to 100 different positions. This, of course would require a strobe flashing at a frequency of 20 to 100 flashes per second if we kept the shutter open for a second. An exposure time of 1 second is easy to accomplish with a regular camera but many digital cameras have a limited maximum exposure time.
Recently I attached a mechanical, rotating disk type, stroboscope to a Kodak DC260 camera (which has a maximum exposure time of 4 seconds) and used an exposure time of one second to obtain the photograph shown here. The subject was placed against a large, black, velvet background. The lighting level was adjusted so that the results obtained were of an acceptable quality by making a few preliminary tests and judging the quality of the images on the LCD display screen of the camera. Very convenient and effective!
By the way, from this example made over a period of 1 second, the camera recorded about 17 separate images of my amateurish attempt to swing a glof club. From this it can be determined that the mechanical stroboscope's disc was turning at about 17 revolutions per second.
Note that, as with traditional cameras, the background (which should have reproduced very dark since it was black velvet) and those parts of my body that remained essentially in the same position appear significantly overexposed because they reflected light to the same location on the CCD. On the other hand the moving club shaft was exposed in different positions on the CCD with every pass of the stroboscope disc. The moving club, therefore, is exposed only once on any given area on the CCD and reproduces with less exposure than the stationary parts of the scene. One could improve slightly on the tonal range of the image by making the subject wear dark clothing while painting the moving club shaft with a highly reflective or white paint.
If one leaves the shutter for too long the sequential images will start to overlap until a point is reached that they all blend into a uniform "blur" and the specific position of the subject with any given flash discharge can no longer be perceived. If one is interested in motion detail then, in a film-type camera, it is possible to simply put the film in motion while the stroboscopic light flashes (or the mechanical disk rapidly rotates in front of the camera's lens) and the subject performs in front of the camera.
Using a standard 35mm camera the film is simply advanced one frame at a time, with the lens covered, into the take-up chamber without exposing it. Then, setting the camera's shutter to &quo
Samsung Digital Imaging ST10
The biggest theme of digital devices in 2009 is ‘TOUCH’, I think. More advanced touch type cell phones are popular (Recently released cell phones are touch type), and a lot of MP3 players supporting touch LCD has been released. (Samsung P3, Cowon S9, and iPod touch show the convenience of touch interface.) On top of that, we can meet touch screen interface devices anywhere such as electronic dictionary and navigation.
Digital cameras which were considered as a button type also satisfy users with touch interface products. This time, I’m going to review the VLUU ST10 from Samsung digital imaging. This is a compact digital camera adopting haptic UI, and supports MP3 and PMP functions. Also, by adopting unique lens cover, perfect self shot is possible.
I could see there were many distinguishing things from others. Is the touch type more convenient than other products? Let’s check it out with test
