PIXEL
A scanner.
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
Because the focal point of the convex mirror will always be at a 'virtual' place. Convex mirrors focus the image at a definite point.
semiconductor image sensors these are special photo sensing sensors,these are very big deep areas to explain here how these sensor capture, it but simple answer for you these are simply found in digital cameras webcams phone camaeras, according to image it will produce some electrical signals and it will be collected by associated electronic circuit then it will be sent to image processor,it the it will be displayed in the proper image viewing element

a pixel is the smallest element in an electronic image
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.
Your reflection is reverse in a mirror because it is an image that is bounced back from a single point. These images cannot flip.
a pixel is the smallest element in an electronic image
A convex lens that focuses light to form an image at the focal point is known as a converging lens. This type of lens causes parallel light rays to converge and meet at a single point called the focal point, creating a real image.
A lens focuses light by bending and refracting it, bringing the rays together at a single point called the focal point. This process creates a clear and sharp image by ensuring that light rays from each point on the object converge at the corresponding point on the image.

A pixel.
Mega means many or large amount and pixal is a single point in an image. Megapixal is to have multiple points
All concave spherical mirrors have a defect known as spherical aberration, which causes light rays coming from a single point on the object to not converge at a single point after reflection, resulting in a blurred image.
