I've created an application called Color Blend which allows you to identify colors by pointing the camera at an object. I'm decoding the preview stream so I am able to do this continually without manual intervention. I have only been able to test it on a HTC Hero and would really appreciate people who have other devices to download it and comment on performance, camera facilities etc. I'm just choosing the camera preview size closest to the screen resolution but not I'm sure how well that scales to the higher end devices.
Here is the market blurb:
"Point the camera at an object and Color Blend will tell you what color it is in words!
- Fully automated, continual process; no need to press buttons
- Facilities to adjust white balance, brightness, contrast, etc.
- Localised for US and rest of world (colour vs. color!)"
The 'web standard' color scheme contains the 16 W3C standard html named colors. The 'web extended' scheme contains the colors supported by most browsers (based on X11). The 'common' (default) color scheme is a subset of the extended scheme that I randomly chose.
The bar at the bottom is a gradient produced from the past x colors you have seen. You can activate manual mode by pressing on the swirling arrow icon.
All feedback welcome!
