Lens calculator

I would like to convert a lens calculator from Flash-based to something that will run on an iPhone, iPad,? and Android. The calculator requires inputs (select a camera type, select a lens, select field of view) and calculates outputs (image resolution, object distance) and displays the calculated numbers and representative photos.? Representative photos are scaled and/or cropped from a set of base photos.? The Flash version is at [[url removed, login to view]][1].

## Deliverables

This calculator is used to security system designers.? They have to choose the appropriate cameras and lenses to cover the area of interest be it parking lot, bank, casino cash room, etc.? The calculator tells the designer how much they can see and also gives them an example of the image quality.? The designer is not always at their desk so a portable application is a good marketing tool for my company.? I have not seen any other lens calculators nearly as useful as this one and I would like to capitalize on the market quickly.?

In its current form, the calculator is free-form meaning that the user can experiment with different inputs and see the results immedately.? There is no set sequence or "wizard" flow.? I would like to maintain that free-form functionality however I'm not sure how everything on one small screen will fit.? Maybe the screen shows the key parameters and there are other second tier parameters.? Key parameters (as you can see from [[url removed, login to view]][1]) are

1. camera settings: resolution

2. lens: select lens, and lens slider

3. dist to object

4. image resolution

5. field of view

6. overview picture

7. zoom-in picture

8. Theia logo

3, 4, and 5 are shown in two places on the Flash version, once as input, once as ouput.? They could all appear as input/output fields in the iPhone app, only showing up once.?

Second tier inputs are

1. camera settings: sensor size

2. lens: field of view in degrees (this may be a first tier input if there is space)

3. lens: focal length (mm field)

4. unit system

5. application picture choice

6. aspect ratio and vertical FOV

2 and 3 are both inputs and outputs and are related to the lens selection and lens slider in the first tier settings.

Caveat: I don't have an iPhone, iPad, or an Android so I don't have a feel for the general look and feel of the applications.? Also, I don't know if the programing languages are similar enough that this application can be ported from one to the other.?

You may bid on one or more translations (iPad, iPhone, Android)

Flash source code is proprietary but will be provided to the selected worker for modification to the other devices.
