Do Camcorders/ Video camera have Sensors in them?

Click For Summary

Discussion Overview

The discussion revolves around whether camcorders and video cameras contain sensors, the types of sensors they may have, and how these sensors could potentially be utilized in robotics. Participants explore various aspects of camera technology, including autofocus mechanisms and optical sensing apparatuses.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses curiosity about using a video camera's components to provide "vision" for a robot, questioning whether cameras have sensors and what types they might be.
  • Another participant mentions that autofocus cameras have mechanisms to determine distance from subjects, suggesting that this involves some form of sensing.
  • Some participants speculate that decent cameras likely include optical sensing devices, such as CCD arrays.
  • It is noted that analog cameras typically have light intensity sensors to adjust shutter speed and flash, although uncertainty exists regarding digital cameras.
  • A participant humorously suggests that cameras contain "gnomes" that create images, indicating a playful take on the technology.
  • One participant warns against attempting to hack a broken camera without technical information, while asserting that all cameras contain some type of sensor, commonly CCD or CMOS.
  • A participant describes an interesting component found inside a camera, speculating on its function and inviting further discussion, while another questions the technical understanding of circuit boards.
  • There is a mention of the complexity involved in adding vision to a robot, with a suggestion to seek out project ideas from external resources.

Areas of Agreement / Disagreement

Participants generally agree that cameras contain sensors, but there is no consensus on the specifics of these sensors or their functions. Multiple viewpoints and some playful speculation exist regarding the nature of camera technology.

Contextual Notes

Some participants express uncertainty about the technical details of camera components and their applications in robotics, indicating a range of expertise among contributors.

Curious. I have a video camera and I've decided to take it apart. I posted a thread a while ago about building a robot, so It would be nice if somehow i could use something from this camera to give it "vision" or "Senses". So I want to know. Do these things have sensors in them? Is that how they work? What kind of sensors if they do?

Any autofocus camera will have a way of knowing how far it is from the subject.

http://en.wikipedia.org/wiki/Autofocus" goes into some details about the methods.

Well if the camera still works, you could incorporate it into the robot to give you video feedback. Otherwise, I don't really think there's much you can do with it, other than possibly making a line, color, or light/dark sensor (but it might take some advanced soldering and circuit modification).
 
In addition to ranging for autofocus that DaveC brought up, analog cameras will, usually have sensing for overall light intensity to adjust shutter speed and flash. I don't know about digital cameras.

No sensors, there is a gnome in each camera, gnome with a canvas, palette and paintbrush.
 
For video you need two sets of imps, one painting each image and another blowing it dry.
 
Now, now people be nice..

I'll answer some of your question after that use Google and wikipedia.com
for more detail..

1) Don't even try to hack an old broken camera..
unless you have tech information on that camera your wasting your time.
2) All camera contain some type of "sensor" Cmos or mos.
the most common is a ccd a type of cmos sensor.
3) Here's where you should go to wikipedia and look up "CCD"..
How they work is much easier to understand with pictures.
4) Adding vision to a robot is a very complex process...
I would recommend that you visit a site like "make"...They have projects
you maybe able to do to add simple vision to your home bot.

Well that's it from me... good luck...

Yes Video camera and camcorders do have sensors. without ssensors hardly there are anymore gadgets produced.

Alright so after taking it apart some more. I can across a very interesting piece. Makes me think of a turbine(I know that it is not). At one end it has a white cap with 4 holes with metal rods that then pass through a short(very short) glass tube and then through some gears and into another things with all these green and copper tightly packed teeny tiny wires. and then that's connected to the part that you put your eye at..Could this be it? If not, what is it? I'll upload a picture

Hm. If you don't know what a circuit board is, is there any possibility this is over your head?

Of course it is..which is why I'm buying a kit to learn off of. But I figured I'd pick up some knowledge here too =]
