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

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

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.

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.
Dear Jerold,



Short for Pic-ture El-ement, a pixel is a single point in a graphic image. Graphics monitors display pictures by dividing the display screen into thousands (or millions) of pixels, arranged in rows and columns. The pixels are so close together that they appear connected.



The number of bits used to represent each pixel determines how many colors or shades of gray can be displayed. For example, in 8-bit color mode, the color monitor uses 8 bits for each pixel, making it possible to display 2 to the 8th power (256) different colors or shades of gray.



On color monitors, each pixel is actually composed of three dots -- a red, a blue, and a green one. Ideally, the three dots should all converge at the same point, but all monitors have some convergence error that can make color pixels appear fuzzy.



The quality of a display system largely depends on its resolution, how many pixels it can display, and how many bits are used to represent each pixel. VGA systems display 640 by 480, or about 300,000 pixels. In contrast, SVGA systems display 800 by 600, or 480,000 pixels. True Color systems use 24 bits per pixel, allowing them to display more than 16 million different colors.

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.
