Camera Definition and 306 Threads

I'm making a physics game engine, and I have some decent camera functionality. Essentially, the camera has a translation (vector) and a rotation (quaternion), and functions exist to easily move the camera along any of seven degrees of freedom (pitch, yaw, roll, strafe, elevate, move, zoom)...

Usha wants to take a picture of her own image in a plane mirror. At what distance should the camera lens be focussed if it is positioned 2.3 m in front of the mirror? is it 2.3*2 ?... 4.6m ??

[SOLVED] High Speed Camera Problem Rotational Kinematics So I'm pretty sure I'm just asking someone to point out the obvious for me, but I've been trying to figure out where to start on this problem for way too long. I don't want the answers, just some guidance on how to start in terms of...

Homework Statement A CCD camera with 1024x768 pixels with a pixel pitch of 6 micrometres is positioned at the primary image of a microscope with a x60 objective and a 160mm tube length. The resultant image is viewed on a video monitor with a diagonal size of 43cm and an aspect ratio of 4:3...

Just curious... How can you make a simple hi-speed camera or a multiple flash making machine(?)? If there is a way, do tell :biggrin:.

Homework Statement A hot air balloon has just lifted off and is rising at the constant rate of 1.87 m/s. One of the passengers realizes she has left her camera on the ground. A friend picks it up and tosses it straight upward with an initial speed of 11.6 m/s. If the passenger is 2.70m above...

A camera with a focal length f of 6 cm is used to take the picture of a person who is 180 cm tall, standing at a distance 3 m in front of the camera. How big will the image of that person be on film? How far behind the lens (assumed to be very thin) must the film be placed? I tried using...

Hi, As an electrician I'm tired of lifting floorboards to find problems in domestic propertys and having every fault finding call ending up like an episode of fawlty towers because of inter-connections, ludicrously planned cable runs and all kinds of other appalling wiring practices exhibited...

Hello, I have somewhat of a technical question and was hoping you would be able to help me. I have a display that is 852 (x3) x 600. This means that that there are 852 x 600 of the red, blue and green filtered pixels. Say however that I am looking at a completely red object, thus only red...

what kind of image is formed from the pinhole camera when the pinhole is small?what kind of image is formed from several pinholes?what kind of image is formed from a large pinhole? how would i describe these images?

how to make a pinhole camera for my school project.any suggestions?

Is a camera very much like a normal (i.e. perfect vision) eye? If we wear lenses, we will like the camera be able to 'see' focused images very far away or very close which is like zooming in or out with the camera. Some people with eye problems like myopia cannot see a focused image beyond...

From observation, whenever I want to 'zoom in' in a camera, the lens expands outward. What is the reason behind this? My guess, 'zoom in' => greater magnification => object closer to the focal point of the lens (although greater than the focal lengths since otherwise the image would be...

When taking photos with a digital camera there is usually a burst of light before the photon is taken. Why is this? Is it because there is usually not enough light reflecting off the object being photographed. It is this reflected light that is what is being recorded on the film inside.

I need a super cheap (under $30ish) infrared camera for detecting human body heat to confirm the presence of the person, i.e. it doesn't have to record exact temperatures or create clear images, but just record the presence of the person. No visible camera is needed, just infrared. Does anyone...

http://en.wikipedia.org/wiki/Depth_of_field" stands for the range that is sharp on a photograph. The bigger the diafragma (camera opening) the smaller the range that will be sharp on the picture. A bigger diafragma also means a shorter shutter opening (so the picture doesn't become too...

***Warning, if you have dial-up don't open this page. I decided to take some pictures at school with my new camera. My school has a beautiful campus. Here is the brand new Kim engineering building. We did a google search on the chairs in our computer lab and each one costs a grand...

As far as I understand, the film inside a photo camera is positioned in such a way that every light ray that hits some spot X on the film comes from a single source on the object being photographed. Here's what I mean: http://static.howstuffworks.com/gif/camera-diagram3.gif The various...

Ok, I'm looking for an entry level digital camera, nothing fancy. as low as 3 MP will do, but I've also seen some as much as 6 which are still pretty cheap. I don't really know what to look for in a digi, but I do know that having the biggest lcd possible is a major plus, I definitely want...

A point source of light 2.0m away from the a pinhole camera creats a 12cm wide spot of light on the screen 1.0 deep inside the camera. How wide is the aperture of the camera. I thought this was a magnification problem, so I set up the equation: h_i = .12m, h_o = x, s_i = 1m, s_o = 2.0m...

I make Daguerreotypes (http://en.wikipedia.org/wiki/Daguerreotype) and I have decided that I want to move from the standard flat-plane photography and make images on silver domes instead. I have domes that are 1.85" in diameter and I want to replicate the effect that a garden gazing ball gives...

A parachutist descending at a speed of 10m/s drops a camera from an altitude of 50m. How long does it take the camera to reach the ground? Is speed the same thing as velocity in this case? If not, what do I do? I assumed it was the same and went: Vi= 10; a=-9.8; d=50 goes into formula d=Vit...

Does anyone have a "Vivitar" camera? I can't seem to download images from my new camera to my computer. Help!? :confused: Pete

My Fuji FinePix S7000 is sometimes showing lines, or purple streaks on the LCD when I take a picture. These lines and streaks are also on the downloaded photo. Is this something that can be fixed, or do I need a new camera? :cry:

Hi! I am having trouble with this question: You are trying to photograph a bird sitting on a tree branch, but a tall hedge is blocking your view. However, as the drawing shows, a plane mirror reflects light from the bird into your camera. If x = 4.3 m and y = 4.5 m in the drawing, for what...

this is what i would expect from a conical perspective on a flat plane that is how a basic camera works, the farther the film from the hole the bigger the projection of the image but insted the image gets blurry, why? in a close image the center of the picture is closer to the viewer than the...

Hi! I'm trying to implement a FPS-camera. I need to calculate a new vector from another one, rotated a. This is of cource in 2D. Is this correct: x' = x * ||v|| sin a / y y' = - y ||v|| cos a / x

This is probably painfully simple, and is not a 'brain teaser' as such but this seemed like the most suitable forum. My bro and I were having a discussion tonight and we stumbled across a problem that probably lead to more discussion than it is worth, but since we still can't come up with a...

Do we have any Candid Camera fans? This is still running on PAX; in fact I have it on right now. Peter Funt, son of the originator, Allen Funt, hosts the show. He doesn't have the budget that his dad had but the show is still worthy of the name. They have done some great stuff! Right now...

There's probably nothing anyone can do to help me, so this is mostly a *****, but I have a Nikon Coolpix 3100, which is a great camera except for the battery life. Now, I know most digital cameras have crappy battery life, but mine is rediculous. What makes me think something can be done about...

Hey guys; I'm having an add problem with my digital camera. It's an Olympus C-50 Zoom. I plug it into my USB port, and it says "New Hardware Found", then it shows that it recognizes it as what it is, the digital camera, then it says it found a "USB Mass Storage Device". It shows no errors...
