A pinhole camera is a very simple camera with no lens and a single very small aperture. Simply explained, it is a light-proof box with a small hole in one side. Light from a scene passes through this single point and projects an inverted image on the opposite side of the box. Cameras using small apertures, and the human eye in bright light both act like a pinhole camera.
The smaller the hole, the sharper the image, but the dimmer the projected image. Optimally, the size of the aperture should be 1/100 or less of the distance between it and the screen.
A pinhole camera's shutter is usually manually operated because of the lengthy exposure times, and consists of a flap of some light-proof material to cover and uncover the pinhole. Typical exposures range from 5 seconds to hours and sometimes days.
A common use of the pinhole camera is to capture the movement of the sun over a long period of time. This type of Photography is called Solargraphy.
The parts you need are a light tight box with a screen at one end and a hole in the other. The size of the hole will depend on the length of the box. A hole punched in the end covered by silver foil with a small hole in it will project an image. Getting the right size would be experimental. However it must be an absolutely clean edged hole. You can actually cover a window with something black and put a small hole in it and put up a white sheet on the oposite wall to the window. The room must be in total darkness. Make a large hole in the black sheet then place you pinhole over that and experiment with the sizes. Make sure the hole has a clean edge. You should see an upside down image.
A pinhole camera is also known as a dark chamber camera. A pinhole camera is basically a camera in the shape of a closed chamber or box. On one of the sides of the box is a small hole which creates the image of the outside space on the opposite side of the inside of the box.

What is difference between digital image processing and digital signal processing?
Digital Image Processing is a type of Digital manipulation pertaining to pictures and video. "Photoshopping" a digital picture is an example of Digital Image Processing. Another example is what takes place in a digital camera when the image is captured on the image sensor and converted into a JPEG file to be saved on a memory card. Digital Signal Processing is a generic term for any manipulation of a Digitally encoded signal, such as Audio, Video, or Radio Signals. This also includes Digital Image Processing where there is a signal being sent from one part of a system to another, such as in a digital camera. There are Microprocessors that are specifically built to process digital signals known as "Digital Signal Processors" (or DSP's).
What are the similarities of digital camera to ordinary camera?
everything
Pinhole camera and human eye similarities?
I think a pinhole camera is similar to the human eye because like the pinhole camera when it sees something it reflects the image but it is an inverted image. With the human eye the brain corrects it and turns it the right way up. The pinhole cameras image is not corrected because it does not have a lens.
