The resolution of an image is always?
[no. horizontal pixels] * [no. of vertical pixels]
How is clarity of an image related with pixel?
Any digital image is made of pixels - the more pixels in the image, the greater the detail and the greater the clarity.
Compute the Size of 800x600 image at 240 pixels per inch?
If the image is 800 pixels by 600 pixels at 240 pixels per inch, then the image size is (800 / 240) by (600 / 240) or 31/3 by 21/2 inches.
The individual dots that form the image on a monitor are called?
pixels
What is an image that is created using pixels?
An image is made up of pixels, or tiny squares that each have a designated color. the pixels are normally so small that you don't see them. However, sometimes a picture looks blurry when resized. That blurry image is a pixelated image.
How is image resolution expressed?
Image resolution is usually expressed by giving the dimensions of the image in pixels. The size of an image that is 640 pixels wide and 480 pixels tall would be expressed as 640x480. 640x480 is read as "six forty by four eighty".
What is the effect of changing the numbers of pixels in an image?
if we have the more pixels the resoultion will be more high
What is resolution dependent?
Resolution dependent is an image that is composed of a particular amount number of pixels. The quality of the image that is produced depends on the amount of pixels.
What is the relationship between image resolution and size?
The image resolution of a picture is broken into pixels. The amount of pixels in the picture depends on the size of the print. There are approximately 100 pixels per inch in a picture.
What is image data?
When a person refers to image data, they are most likely referring to the internal code of a picture file that tells the computer information it needs to display the image, such as (but not limited to) what color the pixels in an image are, how many pixels an image has, and what image type it is.
What image is composed of pixels on a grid?
a bitmap
What are the small building blocks in a digatal picture when you take one?
I believe that you may be referring to pixels. Digital pictures are made up of (most of the time) thousands of pixels (depending on the resolution, e.g. there are more pixels in an 800x600 image than in a 640x420 image, given in length x width format). The more pixels an image has, the higher quality and the clearer the image is. Cameras are often rated by Megapixels. A Megapixel, judging from the name, is a block of 1,000,000 pixels. If a camera has 4 megapixels, then the image is essentially split into 4 parts, each containing 1,000,000 pixels for the obvious total of 4,000,000 pixels. However, if it is only 2 MP, then you have only half the pixels, and the image will be nowhere near as sharp. I hope this helped.
