We succeeded in developing a small, light, advanced camera for presentations at low cost. It is designed for mobile use to make a clear distinction from existing all-in-one, stationary products. It can be connected with the USB port of notebook computers. Processing is done in software on the personal computer, and using power supplied via USB made a camera power supply unnecessary. We used a board lens for CMOS cameras of 1.3 million pixels to keep the price low. To increase added value, we developed and added an auto focus function, which is not provided in cheap cameras. For hardware development, we designed and made the mounting circuit for the lens drive. For software development, we developed and made the auto focus algorithm using image data processing, and checked its operation. Moreover, we used CAD to pursue a more functional and externally beautiful design. We made a gypsum model for trial purposes. We achieved good results in making a trial product aimed at commercialization.
