How many bits per pixel are needed to represent a black and white image?
A "black and white" image is generally actually a grayscale image, which is typically represented with 8 bits per pixel. However, you can make images that use only one bit per pixel, making each pixel either fully black or fully white. The images created by the early graphics software MacPaint used only one bit per pixel.
Many pixels make up one image. A pixel is like one tiny piece of an image.
as a simple example assume you want divide a gray level secret image to two shares. Each pixel in the secret image is expanded to four subpixels in each share that consist of white and black so width and height of shares is twice of secret image. first share is an image wich has random pixels of black or white with equal probability. in second share, if corresponding pixel in main secret image is white… Read More
To represent 256 colors it is needed 8 bit per pixel. 1 bit mean 2 colors, 2 bits mean 4 colors, 3 bits per pixel can represent 8 colors... 8 bits = 256 colors.
That depends on how many bits per pixel and how much the image is compressed. For example, a black-and-white (grayscale) image typically has 8 bits per pixel, but a full-color image may have 24 or 32 bits per pixel. JPEG compression may reduce the file size dramatically, sometimes by a factor of 50 or more.
Image processing involves various operations on images. An image is a collection of pixels. Each pixel has its position and resolution.
Types of images are: 1.Compressed image 2.RGB image (True Color Image & has 3 pixels ) 3.RGBA image (True Color Image & has 4 pixel or more ) 4.Grayscale image (Black & White) 5.Palette image (16 colors per pixel ) All i want is to " Like" ! Thanks !
Bitmap image is raster or pixel based image. Bitmap image is made up of pixels, every pixel in grid have its own position and color. Pixels are mapped to the pixel grid, that's why its name is Bitmap.
A pixel is one dot in the image. A 10 megapixel camera will have 10 million pixels that make up the image.
Pixel Pitch is the measurement of the smallest bit of data in a video image. The smaller the size of the pixels in an image, the greater the resolution.
The image is split into a two dimensional grid of pixels. If the brightness of the pixel is below a certain value, it is considered black, otherwise it is considered white. Each pixel is mapped onto 1 bit in memory, and if it is white, a 1 is stored, else a 0 is stored. (Sometimes it is the other way round)
Using 8 bits per pixel, how can represent 256, or 28 shades
a pixel is the smallest element in an electronic image
Image Processing is area in which image is processed based on pixel (spatial) and frequency methods. In spatial method pixel value are subject to change For more details on image processing research visit http://imageprocessing.webs.com/
If you was to cycle each pixel in an image through all its colors then shift it to black and increment the next pixel up one color as in binary would you end up with every picture possible?
yes and no not all pixals will be on there
A pixel is a 'picture element' It's one single dot on the screen, or in an image
Each pixel is made up of 3 colors. Depending on the image is the amount of color is shown of pixel. hoped this helped
A pixel is the smallest area in a digital image. It does not have a unique size, it depends on the amount of detail specified for that image.
The image space is the 2D plane of the image where pixels are located. It represents the spatial space of the image. In other words, when we talk about the location of each pixel in an image, we are talking about image space. On the other hand, feature space is about the radiometric values assigned to each pixel. In case of a grey-scale imagery, only one radiometric value is assigned to each pixel. When we… Read More
The smallest unit an image can be broken down into is a pixel.
It is a "picture element" which is a single dot of color in an image.
10 megapixel will have a larger image size and better image quality to a 8.5 megapixel. I hope this helps
Interpolation. Make a new pixel the average of its surrounding pixel colors.
A pixel is a single dot on a screen or image, it's an abbreviation of picture element

A cheap digital webcam has a 1000 x 2000 pixel image resolution for still images and uses a 24-bit colour scale for each pixel How many bytes of memory space would be needed to store a single image in?
1000 x 2000 x 3 = 6.0 million bytes, or 5.722 MB.
When you enlarge the image, you can see alot of the pixels depending on the pixel count or resolution of the image. There is a definite pixel count that will not change when the image is enlarged or shrank so the pixels either squish together or become to large that they change the resolution and quality of the image.
the smallest computer screen is the pixel.On this pel(picture element or pixel) the image is divided into patrs which is displayed on it(only the portion of image assigned to that patricular pixel)
a pixel is a tiny square of colour. a megapixel is a million tiny squares of colour that make up your image.
You could calculate two perpendicular gradients to each image pixel point. If both gradient are small the pixel pertains to a flat region.
Pixel density. The greater the density, the higher the quality of the image.
Base unit of any digital image. All digital images are created from pixel grid. One pixel can have one color and one level of transparency at time.
Any digital image is made of pixels - the more pixels in the image, the greater the detail and the greater the clarity.
Typical uncompressed colored images use 24 or 32-bits per pixel of an image (RGB 8-bits per color). After some basic math of lets say an 8 Megapixel image quickly becomes a very large file on a computer. A type of compression used is to select some colors (typically called a palette) and for every pixel in the original image select a color in the palette that is closest to it (some other techniques exist to… Read More

The word "pixel" is itself a contraction of the words "picture element", the smallest individual part of a display image. (see related question)
The brightness of the pixel within the image on a scale of 0 to 255
Megapixel means one million pixel in a image.
Technical characteristics: - number of colors (how many bits per pixel are supported) - image size (width x height in pixels - also call image resolution horizontal, respectively vertical) - file size (size in bytes of the file where the image is saved) - display/print resolution, usually in dots per inch/cm (a description on how to output the image) Subjective impressions (for example when evaluating photographs) - subject of the image - background - type… Read More
"Px" is an abbreviation used in many different places for "pixel." A pixel is the smallest element of a screen which when combined with others creates an image. Simply put, each tiny little pixel is a box filled with a certain color. Many hundreds or thousands of these pixels add up to create an image.
A Digital image is a two dimensional array, or a matrix, of square pixels (picture elements) arranged in columns and rows. A digital image is composed of a finite number of elements called pixels (short for picture elements), each of which has a particular location and value. Each pixel represents the colour (or gray level for black and white photos) at a single point in the image, so a pixel is like a tiny dot… Read More
That depend on resolution. Open image in Photoshop and go to Image > Image Size. Pixel dimensions you can see on the top of Image Size window.
No - because the pixels making up the image are either on or off. With a colour bitmap - extra data space is needed to tell the computer what colour each pixel is.
The term pixel is a short form of picture element (pix el) meaning the smallest part of an image that can be defined. For a CRT, TV, or monitor, the pixel is a single point of color combination (Red Green Blue) that can be separately determined and changed. Similarly, for bitmap images, a pixel can be made any color, but only one color per pixel. The concentration of separate pixels may be known as the… Read More
Depending on the original pixel size you can use the image , resize and then adjust the pixel resolution. Its always best to scan in or create in 300 and above DPI
There are two types of images you can work with, vector images and pixel(raster or bitmap images).Vector based software are Adobe Illustrator, CorelDraw and you can work both image types, but you have more capabilities to work with vector images, primer for pixel based software is Photoshop in which you can also work with both image types but you have more capabilities to work with pixel images.
picture element = pixel
A mask is a black and white image of the same dimensions as the original image (or the region of interest you are working on). Each of the pixels in the mask can have therefore a value of 0 (black) or 1 (white). When executing operations on the image the mask is used to restrict the result to the pixels that are 1 (selected, active, white) in the mask. In this way the operation restricts… Read More
For a grayscale image, brightness represents an image adjustment where a constant value is added to all pixel values shifting the grayscale curve on the y axis.
720p = 720 pixel of video quality 1080p = 1080 pixel of video quality 1080p image quality is better than 720p .
