Low-Cost Mobile Phone Microscopy with a Reversed Mobile Phone Camera Lens

The increasing capabilities and ubiquity of mobile phones and their associated digital cameras offer the possibility of extending low-cost, portable diagnostic microscopy to underserved and low-resource areas. However, mobile phone microscopes created by adding magnifying optics to the phone's camera module have been unable to make use of the full image sensor due to the specialized design of t...

Translation camera on mobile phone

In this paper, we report a mobile application which translates Japanese texts in a scene into English. The application is designed to run on a mobile phone with a camera. It recognizes Japanese characters sensed by an onboard camera of a mobile phone and translates them into English.

Design of High Pixel Mobile Phone Camera Lens

The compact, slim and high pixel mobile phone camera is highly demanded with the development of mobile phone, especially the thinner and thinner request of people. To satisfy this need, a mobile phone lens system composed of 1 glass spherical lens and 3 plastic aspheric lenses was designed with Code V. The F-number was 2.85 and FOV was 61°, the effective focal length and back focal length are 5...

Color Correction for the Mobile Phone Camera

The color correction is needed because the spectral sensitivity of the CMOS image sensor (CIS) in each color is neither the same color component for most standard colors nor the appropriate color representation for any output devices. In the conventional method, a color correction is empirically obtained by a large number of iterative experiments, but the result is not so satisfied. In this pap...
