  • 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.

  • 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.

  • Publication number: 20070188652
    Abstract: In a digital camera 1, when the halfway depression operation of the shutter button is detected, the lens position which is in focus for each capture area is detected and stored. On the other hand, when instruction to record is detected, intensity of light is sequentially read out at the stored lens position from the capture area associated with the lens position and the image data is generated. Accordingly, it is possible to acquire image data which is in focus on all objects that have been imaged by the CMOS sensor 4.

  • Publication number: 20070187760
    Abstract: A thin film transistor includes a substrate, and a pair of source/drain electrodes (i.e., a source electrode and a drain electrode) formed on the substrate and defining a gap therebetween. A pair of low resistance conductive thin films are provided such that each coats at least a part of one of the source/drain electrodes. The low resistance conductive thin films define a gap therebetween. An oxide semiconductor thin film layer is continuously formed on upper surfaces of the pair of low resistance conductive thin films and extends along the gap defined between the low resistance conductive thin films so as to function as a channel. Side surfaces of the oxide semiconductor thin film layer and corresponding side surfaces of the low resistance conductive thin films coincide with each other in a channel width direction of the channel.
