How much memory does a pixel need if it is represented in an uncompressed format?

A hex color is represented by three different levels of the RGB (Red, Green and Blue) colours. Each of which is given a level of shade. To represent this the colors usually have a hexadecimal value for each of the RGB which is made up of two numbers each ranging from 0-f so ff would represent completely on. If you were to have all three red, green and blue completely on or ffffff then you would have white. The opposite would be 000000 for black and there are a multitude of colors to be had by mixing them all.
To convert the hex colors to Binary which is what the computer would store as in the memory then you would have f as 1111, ff as 11111111 and so on. So ff being a binary equivalent of eight bits that means for each of the three colors or shades you have (RGB) you must have a byte. So if one pixel contains three colors then each pixel must take up three bytes.
A typical screen resolution of 1024 by 768 pixels would take up 2,359,296 bytes or a little over two megabytes. This is of course assuming you have an image with a 24 bit format.

What is a pixel and how is related to map making?
In digital imaging, a pixel is a single point in a raster image, or the smallest addressable screen element in a display device; it is the smallest unit of picture that can be represented or controlled
What is the dots of light on a computer screen called?

What is the word pixel short for?
picture element2. In media studies "word pixel" refers to the progression of information from words to pixels and to the study of the transformative effect of electronic media on traditional movable type. (J.L. Shear)3. A pixel, for "picture element," is the smallest unit on the screen that can be turned on and off or made different shades. Pixels are tiny squares, not circles.
A color images uses 16bits to represent a pixel what is the maximum number of different colors that can be represented?
maximum number of different colours is 2 power 32
How do you compare an image pixel by pixel in C plus plus?
In order to compare images pixel by pixel, both images must be uncompressed bitmaps of the same size, dimensions and colour depth. If you're looking for an exact match, then you simply compare the pixels in tandem (you can treat both images as being an array of int to speed up the process).
What is used to represent a single pixel in a video memory?
a scalar
How many pictures can a 1gb memory card hold in a 13.6 mega pixel camera?

How much will a 8gb card hold at 16 mega pixels?
In uncompressed raw format, a 16-megapixel image will take 64 MB (4 bytes per pixel, including the alpha channel), at which rate an 8 GB card will hold about 120 images. However, if your camera stores the images in JPEG or some other compressed format, the card will hold far more images.
What is the memory size of 128128 pixel image?
the size of memory is basically depend upon the pixel in that particular picture the size for 128*128 picture will up to some kilo bites. but as we increasing the pixel the resolution and memory size and quality all the things will increase . and a picture which has 20MP resolution is better than 5MP

How many pictures on 2GB memory card in a 5.1 mega pixel digital camera?
A camera with this pixel setting will have more room, but the images may not be as crisp as ones with a bigger pixel count. You can fit approximately 200 pictures of this kind on a 2 GB memory card.

What would be the size memory size of an image if the image is of 3 Megapixels each pixel is of 16 bits?
A digital image in uncompressed format for exactly 3 mega pixels at a color depth of 16bits would take about 6 megabytes of space. The closest typical dimensions to a 3 megapixel image would be 2048x1536 which is exactly 3,145,728 pixels. Most digital cameras will work at 24 bit color depth so an image of 2048x1536 in lossless uncompressed format would take about 9.45 megabytes of space however most cameras will be able to compress this image using jpeg to less than half that size at very high quality settings and maybe to 1/10th (less than 1 megabyte) at good quality settings.
What type of graphic information does Photoshop edit and save?
Vector and bitmap, raster or pixel. Type, shapes like circle are vectors and can be saved and edited if they are in .psd or .tif format saved. Pixel, raster or bitmap images can be edited and saved in any format, Photoshop supports almost any format.
