  • Patent number: 6989864
    Abstract: An image recorded on a photo film is projected through an imaging lens onto an image sensor. In accordance with a selected mode, set values are read out from a data ROM and are applied to a band pass filter having programmable digital filters. Pixel signals from the image sensor are converted into evaluation signals that are correlative with spatial frequencies of the image, and are filtered through the band pass filter with the frequency band determined by the set values. The evaluation signals are integrated, and a peak value of integration values obtained at different focusing positions is determined to be an in-focus position.

  • Patent number: 6987534
    Abstract: An apparatus for adjusting a brightness balance of a stereoscopic camera includes a gain control amplifier and a micro-computer. The gain control amplifier adjusts a brightness balance of a pair of images outputted from the stereoscopic camera by gain. The micro-computer calculates a first evaluation value representing a magnitude of an entire brightness of a first evaluation window established in a reference image outputted from the gain control amplifier and calculates a second evaluation value representing a magnitude of an entire brightness of a second evaluation window established in a comparison image outputted from an adjusting device, and established in an area having a brightness correlation with the first evaluation window. Also, the micro-computer corrects a gain so as to reduce the difference between the first evaluation value and the second evaluation value.

  • Patent number: 6985183
    Abstract: The present invention is a method for exploring the viewpoint and focal length of a fisheye lens camera (FELC). It employs the characteristic of the central symmetry of the distortion of the fisheye lens (FEL) to set its optic axis by means of a calibration target with a plurality of symmetrically homocentric figures. Once the optic axis is fixed, further disclose the viewpoint (VP) of the FELC along the optic axis through a trail-and-error procedure and calculate its effective focal length and classify it to the primitive projection mode. Because the invention is capable of finding out both the internal and external parameters of the FELC and the calibration method is easy, low-cost, suitable to any projection model, and has greater sensitivity corresponding to an increasing in image distortion, the distortive images can be transformed easily to normal ones which fit in with a central perspective mechanism.

  • Patent number: 6985180
    Abstract: An image processing method and apparatus is described for processing a signal from a monochrome or color sensor that may be subject to pixel defects or blemishes. Without prior knowledge of any pixel defects, the processing method examines each pixel value and its neighboring pixel values. A number of tests are applied to the set of pixel values to determine whether the underlying pixel is defective. If the underlying pixel is determined to be defective, the pixel value is replaced by an estimate value derived from the values of its neighboring pixels. Otherwise, the pixel value remains intact.

  • Patent number: 6972791
    Abstract: A solid-state camera device having a matrix of pixels arranged in rows and columns, wherein a subset of pixels of the entire pixel matrix can be read for display and confirmation of photographic conditions to reduce power consumption and decrease time to display the image. In electronic cameras light is focused on the camera device having pixels and the light energy is used to provide an electric signal from each pixel in proportion to the incident light to provide an image signal. The image signal may be displayed on an attached display such as a liquid crystal display. Because most display have fewer pixels than the camera device, the display can not display image information from each camera device pixel.
