  • Patent number: 7375745
    Abstract: A digital imaging device is operated to capture a first image in a digital format. At least two non-contiguous portions of the first image are rendered in a display of the digital imaging device. The at least two non-contiguous portions of the first image are used to align a live version of a second image in the display, wherein the second image is an extension of the first image. The second image is captured in a digital format. A corner matching algorithm is applied to determine an offset of the second image with respect to the first image, wherein the offset is required to achieve a substantially accurate alignment of the first and second images. Application of the corner matching algorithm is limited to an overlap region intervening between the at least two non-contiguous portions of the first image.

  • Patent number: 7209166
    Abstract: Wide dynamic range operation is used to write a signal in a freeze-frame pixel into the memory twice, first after short integration and then after long integration. The wide dynamic range operation allows the intra-scene dynamic range of images to be extended by combining the image taken with a short exposure time with the image taken with a long exposure time. A freeze-frame pixel is based on voltage sharing between the photodetector PD and the analog memory. Thus, with wide dynamic range operation, the resulting voltage in the memory may be a linear superposition of the two signals representing a bright and a dark image after two operations of sampling.

  • Patent number: 7190402
    Abstract: A visual sensor capable of expanding a dynamic range with a little load of processing for arithmetic operations and performing a stable detection not affected by change of conditions such as ON/OFF state of projection of reference light. A multiplying parameter A (A>1) and the number N of times of image capturing are set in accordance with ON/OFF state of the reference light projection. N images are captured with a shutter speed varying by successively multiplying an initial value by (1/A). Values of density of each pixel in the captured images are summed. Values of constants B and C in equations: 1=B·Zmax+C; 0=B·Zmin+C are obtained based on the maximum value Zmax and the minimum value Zmin of the summed values of densities of all the pixels. An output value Z? of each pixel is obtained according to an equation: Z?=B·Z+C, using the determined values of B and C.

  • Patent number: 7187407
    Abstract: A control system for an image file eliminating saving of an overlapped image data part and saving files in a short time and in a power-saving manner. When a digital camera and a personal computer are connected with each other for data communication, the system compares record unit information to identify an image file that the digital camera has with record unit information to identify an image file that the personal computer has, and transfers to save the image file, which includes the record unit information that the digital camera has and the personal computer does not have, from the digital camera to the personal computer. After completing transfer of the image file from the digital camera to the personal computer, the personal computer generates record unit information newer than the record unit information of the acquired image file and transmits the newer record unit information to the digital camera, which can be recorded in the header of the image file newly photographed by the digital camera.
