  • Patent number: 7643083
    Abstract: The data of each pixel of a CCD, acquired from double pre-emissions performed in accordance with a shutter operation, is estimated to determine appropriate luminous energy for actual photography. Specifically, in each frame between the shutter operation and emission for actual photography, a CCD is driven so that only the data of the pixels corresponding to an estimation area is transferred, and the data of the other pixels is destroyed. The estimation area is included in the image pickup area of the CCD and used to determine the appropriate luminous energy. As a result, the time required to transfer pixel data unnecessary for estimation is omitted, thereby reducing the total processing time ranging from the pre-emissions to the emission for actual photography, and realizing prompt actual photography with appropriate luminous energy.

  • Patent number: 7609302
    Abstract: An improved non-uniform sensitivity correction algorithm for use in an imager device (e.g., a CMOS APS). The algorithm provides zones having flexible boundaries which can be reconfigured depending upon the type of lens being used in a given application. Each pixel within each zone is multiplied by a correction factor dependent upon the particular zone while the pixel is being read out from the array. The amount of sensitivity adjustment required for a given pixel depends on the type of lens being used, and the same correction unit can be used with multiple lenses where the zone boundaries and the correction factors are adjusted for each lens. In addition, the algorithm makes adjustments to the zone boundaries based upon a misalignment between the centers of the lens being used and the APS array.

  • Patent number: 7583299
    Abstract: Plural pieces of frame data compose a moving image. When a data writing process of writing previous frame data is in progress at the time when the latest frame data is written at a certain frame period while the plural pieces of frame data are being successively written on a recording medium, it is determined that a delay has occurred in the writing process of writing the frame data on the recording medium. When it is determined that a delay has occurred in the writing process, alternative frame data is written on the recording medium in place of the latest frame data, whereby a data amount to be recorded is reduced. When it is determined that no delay has occurred, the latest frame data is written on the recording medium.

  • Patent number: 7576791
    Abstract: The invention applies wavefront coding to the front of an electro-optic/infrared device to minimize the amount of light which is retroreflected by systems, such as Fowarding Looking Infrared systems, back to its source. The invention (unlike conventional reduction methods) does not rely on reducing the laser power leaving the interrogated sensor, but primarily on controlling its direction. A sensor according to the present invention, which has been wavefront coded for reduction of reflected light, will also effect the direction of the scattered light, thereby significantly reducing that which returns to the zero bistatic angle position. In contrast, a limitation of conventional methods is that once specular reflections are addressed, the remaining retroreflected signal typically results from scattered light at the focal plane which is largely collected and recollimated by the system optics.

  • Patent number: 7570297
    Abstract: A cover glass covers only light-receiving elements formed on a semiconductor substrate of a solid-state imaging device. The other area of the substrate except the light-receiving elements is exposed. An FPC interposed between an optical unit and the solid-state imaging device is formed with an opening for exposing the cover glass and an assembly reference surface of the solid-state imaging device. When the solid-state imaging device is attached to the optical unit, the center of the light-receiving elements is determined as a reference position. The optical unit is directly attached to the assembly reference surface so as to make the reference position coincide with a photographic optical axis of the optical unit.
