How mirror/camera/tv work without human eye like system?

In summary, devices like mirrors, cameras, and TVs do not have a complex visual cortex system like human eyes. Instead, they use lenses to create an image, which is then projected onto a surface. While human eyes use rods, cones, and neurons to detect and interpret this information, devices use sensors and computers to achieve the same result. Essentially, the role of these devices is to manipulate light in a way that allows our brain to create the desired image. This highlights the difference between the natural process of image creation in our eyes and the engineered process in devices.

Mirror/camera/TV etc. don't have a complex visual cortex system/perception like our eyes. Human eyes use rod,cone,neuron and above all perception of brain to make image. How come these devices create the same clear images/scenes at their surfaces by themselves without having the advance eye-brain system like human beings? A photo-detect software can detect and recognize image and a mirror even don't have any mechanical/digital part. Its so easy for materials to create image but so complex for eyes to create image. Is it?

None of the biological "components" mentioned are used to create the image.
The image is created by the lens in the eye, which image is projected on the retina. Same as done by any lens or lens system in optical instruments.
Everything else (neurons, etc) is used to detect, transmit and interpret the information.
The role of these is played by CCD sensor and computers for the man-made eyes. Or just sensitive film in the older times.

I think you are mixing meanings here. If the image is what the brain makes of the light, then it is always the brain that is making the image. Mirrors only change the path of the light ultimately making the image. Cameras are a bit more complicated, but we engineer them (along with video screens) to get our brain to make the image we want.

Related to How mirror/camera/tv work without human eye like system?

1. How does a mirror reflect light without a human eye-like system?

Mirrors have a smooth and polished surface that is able to reflect light rays in a predictable manner. When light hits the surface of a mirror, it bounces off at the same angle at which it hit. This is known as the law of reflection. Therefore, light is able to bounce off a mirror and into our eyes, allowing us to see our reflection.

2. How does a camera capture images without a human eye-like system?

Cameras use a combination of lenses and sensors to capture images. The lenses work similarly to the human eye by focusing light onto the sensor. The sensor then converts the light into electronic signals, which are processed and stored as an image. However, unlike the human eye, cameras do not have a retina or optic nerve to process the light signals.

3. How does a TV display images without a human eye-like system?

TVs use a complex system of pixels, backlighting, and electronic signals to display images. The pixels, which are tiny dots on the screen, are able to change color and brightness based on the electronic signals they receive. This creates the illusion of continuous motion and allows us to see the images on the TV screen.

4. How do mirrors, cameras, and TVs differ in their ability to work without a human eye-like system?

While all three of these devices use different methods to reflect, capture, and display images, they all work based on the same principle of light and electronic signals. Mirrors simply reflect light, cameras capture and process light signals, and TVs display light signals as images. However, each device has its own unique components and processes that make it function.

5. Can mirrors, cameras, and TVs work without any human interference?

Yes, mirrors, cameras, and TVs can all function without human interference. However, they do require setup and maintenance by humans in order to work properly. For example, a TV needs to be plugged in and turned on, a camera needs to be focused and have a memory card, and a mirror needs to be positioned correctly. Once set up, these devices can work without any human intervention.
