what is a digital still image video camera?

Answer 1

a digital still image is an image produced by a normal digital camera.

Some digital video camera will take still pictures as well as video.

Answer 2

Digital Still Image Video Cameras

Answer 3

There's generally very little difference in the detectors between still cameras and video cameras. The differences have to do with how the images are treated. In the case of a still camera, each image is treated as a stand-alone image.

A video camera basically takes a continuous stream of still images and stores them into a single file. The concept is identical to a film movie camera, where each "frame" of a movie can be considered to be a single still image.

Some still image cameras have the circuitry to continually acquire still images in a stream, making them behave like video cameras as well.

Even some cell phone cameras, which are normally still image cameras, can take videos.

Digital still cameras are cameras whose primary purpose is to capture photography in a digital format. Initially, a digital camera was characterized by the use of flash memory and USB or FireWire for storage and transfer of still photographs (though some early cameras used a serial port connection), and this is still the common meaning of the unadorned term. Many modern digital photography cameras have a video function, and a growing number of camcorders have a still photography function. However, even a low-end still camera can take far better still pictures than a mid-range video camera, and mid-range still cameras have much lower video quality than low-end video cameras. In addition, some newer camcorders record video directly to flash memory and transfer over USB and FireWire. Among digital still cameras, most have a rear LCD for reviewing photographs. They are rated in megapixels; that is, the product of their maximum resolution dimensions in millions. The actual transfers to a host computer are commonly carried out using the USB mass storage device class (so that the camera appears as a drive) or using the Picture Transfer Protocol and its derivatives, in addition firewire is becoming more popular and supported among more digital cameras. All use either a charge-coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS) sensor or novel sensors based upon either of those two principles, i.e. chips comprised of a grid of phototransistors to sense the light intensities across the plane of focus of the camera lens. CMOS sensors are differentiated from CCDs proper in that it uses less power and a different kind of light sensing material, however the differences are highly technical and many manufacturers still consider the CMOS chip a charged coupled device. For our purposes, a chip sensor is a CCD.

It is necessary to take you in the field of movie film, there are 24 individual still frames, it means in a second 24 times a still image is taken in and the film is moved that much ahead. Those 24 frames moved in a second our eye feel the moving picture.

Video camera is doing same with little difference. there are two
standard PAL and NTSC. Pal standard takes 25 fps that is frames per seconds and NTSC 30 fps.

Now the very important part of an image. Number of pixels per frame decide the quality of image. Pal standard use 720 x 576 pixels per frame and NTSC use 720 x 486 pixels.

This frame size is good for movie and to see on computer or TV screen but not good for printing. 720 X 576 @ 72 dpi image size is 10" x 8".

Photo printing, for better quality need image at 300 dpi, 720 x 576 image converted @ 300 dpi the print size is 2" x 1.9"

Entry level DV cameras or still cameras and all types of modern mobiles with video capture facility are only good for viewing not meant for taking prints. For important events particularly our loved ones the video storage should be in full frame, not in MPEG1, VCD, AVI all are low quality standards, use for smaller storage space compare to full frame storage.

Soory, such a lengthy explaination. still image in a video camera is plain and simple sales promotion, it is not much of a use but a fun, in moving video suddenly some one taken a snap shot like effect is created.

Please for all the readers do not use low quality storage for still images or video of your loved ones, if you fell to do so, you will be sorry, when that full frame is needed for further use.

You can't change the format. The computer's not treating the still as a video - it really is a video! What you need to do is extract a still from the video with whichever video editor you use. It's easy but the quality won't be great. Most media players, such as VLC player, can extract stills - you don't *need* to use an editor.

Answer 7

It depends on the format of your DV. If it writes images to a memory card, you should be able to plug in via USB and simply browse to the folder and copy them onto your PC. If it's Windows, then Windows Movie maker should just be able to import them.
