What happens to the image formed when the bottom half of a convex lens is painted black and an object is placed in front of it?

The image is unchanged in shape, size, position, and details, but its brightness (intensity) is reduced by half.


What happens to an image when the focal length of the lens is reduced?

If the Object you are 'focused' on stays in the same relative position to the lens, then the image will appear SMALLER on the Focal Plane. For example, the image using a 50mm lens will be LARGER than using a 28mm lens.


What happens when half the lens is covered with a black paper longitudinally?

The convex lens will form complete image of an object, even if its one half is covered with black paper. It can be understood by the following two cases. Case I When the upper half of the lens is covered In this case, a ray of light coming from the object will be refracted by the lower half of the lens. These rays meet at the other side of the lens to form the image of the given object, as shown in the following figure. Case II When the lower half of the lens is covered In this case, a ray of light coming from the object is refracted by the upper half of the lens. These rays meet at the other side of the lens to form the image of the given object, as shown in the following figure.


What will happen if cover half of the concave mirror?

Intensity of image decreased


When you cover the top half of an object what happens to the image formed by a convex lens?

You see the bottom half of the object, and whatever you covered the top half with.

What does intensity mean in photography?

Intensity is the quantity or degree of any quality. In photography, intensity generally refers to the quantity or degree of light in an image. You can increase the intensity by using a faster shutter speed or a larger aperture. Intensity may also be referred to as exposure.


What happens to resolution when image is maginfied to 400x?

Why we need image segmentation?

As a simple answer I can say: we do segmentation to separate homogeneous area. IN image processing it can be number of pixels with the same intensity in general.


What does image scanner do?

The bar code reader is special type of image scanner. Image scanners convert any printed image into electronic form by shining light onto the image and sensing the intensity of the light’s reflection at every point.
