Real images can be obtained on the screen,whereas virtual images can't be obtained on the screen
If an image can be formed on screen it is classified as real. Virtual images cannot be projected on an image.
Image processing involves various operations on images. An image is a collection of pixels. Each pixel has its position and resolution.
Binary images, Indexed images, Grayscale images, True color images
For a 12 x 12 inch print your ideal image resolution dimensions should be 3600 pixels by 3600 pixels. At a minimum your dimensions should be 1800 by 1800 pixels. Larger mega pixel producing cameras are often better when you want to crop your image down to smaller sizes.
Resolution is defined as the smallest number of discernible detail in an image. Spatial resolution is the smallest discernible detail in an image and gray level resolution refers to the smallest discernible change is gray level.
Resolution of image is used to determine the quality of image in digital camera.
The term is "resolution." Resolution refers to the quality and clarity of an image, typically measured in pixels for digital images. Higher resolution images have more detail and appear sharper.

Depend on image resolution. You can see image resolution in Photoshop from Image > Image Size. Pixels are just the tiny dots that form images, they are not a form of distance measurement. To demostrate this, take for example a 40 in. TV. That 40 inch TV might contain 1920 x 1080 pixels to make up the screen, but likewise, a computer screen that is only 20 in. can also have the same amount of pixels.
You can download High Resolution images online from the Image Source website. Once on the website, you can view hundreds of royalty free high resolution images.
An image that can be seen but not projected on a screen is called a real image. Real images are formed when light rays converge at a point, creating a visible image that can be observed with the naked eye. They are not able to be projected onto a screen like virtual images.
Computer monitors (and all displays really) work by displaying a matrix of tiny dots (called pixels) in a grid which make up the picture on your screen. Display resolution is simply the number of pixels your screen is displaying. Example: 800x600 display resolution means that your display is made up of 800 pixels horizontally by 600 pixels vertically. The higher the resolution, the sharper the image appears, and the smaller details can be rendered. Inversely, higher resolution settings can also make text, images, and webpages appear smaller on your screen, possibly making them more difficult to read.
bitmap or raster images are in other words pixel images and every pixel image must have resolution, resolution is number of pixels per inch, cm
Image resolution is very much important. An image in a wrong circumstance with wrong resolution can be looked terrible. For web images, the resolution for a same size image should be 72 on the screen. A perfect pixel and right size are needed for a correct line-up. If the image resolution is very much high, it will break the page lay out. For printing purpose, image resolution should be 300 PPI so that it remains unbroken with a 'screen'. If you look a magazine photo under a magnifying glass, the above mentioned conditions can be understood. Low resolution image looks fuzzy. Black type and black panels are considered as solid areas in print. For this, image resolution should be higher than usual for avoiding broken text. For supplying flattened artwork, I complete my artwork at 600PPI but I try to produce PDF/ X artwork to overcome this situation. For that, an overdo of resolution is not hampered and a pin-sharped result can always be obtained.
