  • Imaging device with automatic control function of light for shooting
    Publication number: 20070201854
    Abstract: When an auxiliary emission auto focus has been set by operation and through image display is started, a CPU 9 starts an operation of acquiring a single frame among those sequentially picked up at a predetermined interval. Next, the CPU 9 calculates an EV value, judges whether a LED 16 state. If the LED 16 is in the ON state, the CPU 9 judges the calculated EV value. If the EV value is equal to or more than EV5, the CPU 9 images a single frame after temporarily turning OFF the LED 16, and then turns the LED 16 ON to judge whether the shooting scene is really dark. Next, the CPU 9 calculates the EV value. When judged that the EV value is not equal to or less than EV3, the CPU 9 judges that the shooting scene is not dark and turns OFF the LED 16.

  • Card type device capable of reading fingerprint and fingerprint identification system
    Patent number: 7260247
    Abstract: A card type device is mounted on a card slot of an electronic appliance. A transparent cylindrical-shaped roller is provided at an edge portion of a housing such that an outer peripheral plane of the roller is projected from the edge portion. A one-dimensional image sensor is provided inside the roller, which acquires one-dimensional fingerprint data of a finger of a user, and this fingerabuts against the outer peripheral plane of the roller. Since the finger abutting against the outer peripheral plane of the roller is moved, the roller is rotated, so that one-dimensional fingerprint data which are continuously acquired by the one-dimensional image sensor are synthesized with each other to produce fingerprint data as a two-dimensional image. The synthesized fingerprint data is transmitted to the electronic appliance which carries out fingerprint identification.
