  • Patent number: 7920191
    Abstract: When driven in an all-pixel read mode, a CCD (1) outputs, with each horizontal sync timing signal, captured image signals including signal charges arranged in a different order from that in which the pixels are actually arranged on a photosensitive surface of the CCD. During this time, the respective pixel signals are digitized sequentially by an A/D converter (5) to corresponding image data, which are then temporarily stored in units of a line in a line buffer (7) via a data distributor (6). In this case, an address generator (8) generates, for the respective image data, write addresses to store the respective image data in the line buffer (7) in the same order as the pixels of the photosensitive surface are actually arranged. In accordance with these write addresses, the data distributor (6) distributes the respective image data to appropriate addresses in the line buffer (7), thereby storing the image data there (FIG. 1).

  • Patent number: 7916194
    Abstract: An image pickup apparatus includes an element-including optical system, a detector, and a converter. The element-including optical system has an optical system and an optical wavefront modulation element which modulates an optical transfer function. The detector picks up an object image that passes through the optical system and the optical wavefront modulation element. The converter generates an image signal with a smaller blur than that of a signal of a blurred image output from the detector by performing a filtering process of the optical transfer function to improve a contrast. A focal position of the element-including optical system is set by moving the element-including optical system to the focal position which is corresponding to a predetermined object distance using a contrast of the object based on the image signal.

  • Patent number: 7911503
    Abstract: A measurement line segment projection unit (400) projects, onto a sensed image, a three-dimensional model which is arranged at the position and orientation of a physical object (199). A search range is set for each side of the virtual object projected onto the sensed image, near the side of the virtual object in the sensed image based on a positional relationship between the side and other sides of the virtual object. A side of the physical object (199) on the sensed image is searched for within the search range for each side of the virtual object. The position and orientation relationship between the physical object (199) and an image sensing device (50) is calculated using the correspondence relationship, determined based on the search result, between each side of the three-dimensional model projected onto the sensed image and each side of the physical object (199) located on the sensed image.

  • Patent number: 7889258
    Abstract: A system of taking images of different sensitivities at the same time uses both an image sensor, and an auxiliary part to the image sensor. The image sensor element can be a photogate, and the auxiliary part can be the floating diffusion associated with the photogate. Both the photogate and the floating diffusion accumulate charge. Both are sampled at different times. The floating diffusion provides a lower sensitivity amount of charge than the photogate itself. The system can have a photogate and floating diffusion in each pixel along with a select transistor, a reset transistor, and a follower transistor. All of this circuitry can be formed of CMOS for example. The system can also operate in a column/parallel mode, where each column of the photo sensor array can have a column signal processor which samples and holds the reset signal, the floating diffusion signal and the photogate signal.
