what is ,''pixel'' ie 1.6 mpixel like that in cameras?

Answer 1

a pixel is a small square of one color (made by the mixing of red, blue and green). they all hav almost the same dimensions (if u zoom in a picture u c them)..

The more there are pixels, the bigger the picture gets. and the bigger the picture gets, the better quality it gets, but the more space it takes on your memory..

1 megapixel is a resolution of the picture which is 800 pixels by height and 600 pixels by lenght, so that makes 800*600, or 480 000 pixels...
that way 2 Mp is 1600*1200 and so on.. u can calculate 1.6 Mp if u want.

these days, the best cameras are of about 12 Mp and regular mobile cameras are between 2 and 3 Mp..older phones hav VGA cameras, which is 200*150

Answer 2

A pixel is a picture element. Instead of film, digital cameras have an array or grid of light sensors. The more sensors there are, the more detail the pictures can have.

For example with a low number of pixels, a picture of a face might look smooth, but with more pixels a picture of the same person might show the pores and fine lines...

1.6 mpixels means there are 1.6 million sensors in the camera.

Answer 3

Hello
Number of cross sections of line per mm is called pixel. The higher the pixel the better the picture is e.g. an 8 mpxl camera is far better than the 2 mpxl one. It helps in increasing the sharpness of image.

Answer 4

A pixel (short for picture element, using the common abbreviation "pix" for "picture") is a single point in a graphic image. Each such information element is not really a dot, nor a square, but an abstract sample. With care, pixels in an image can be reproduced at any size without the appearance of visible dots or squares; but in many contexts, they are reproduced as dots or squares and can be visibly distinct when not fine enough. The intensity of each pixel is variable; in color systems, each pixel has typically three or four dimensions of variability such as red, green and blue, or cyan, magenta, yellow and black.
