  • Patent number: 7239352
    Abstract: In a signal reading method for a solid-state image pickup apparatus, an estimated photometric value is calculated at the time of preliminary image pickup and compared with a threshold value set beforehand. If the estimated photometric value is smaller than the threshold value, it is then determined that a scene to be pickup up has a narrower dynamic range to execute control reading out signal charges from the main and subregions of the individual photosensitive cell while mixing them together. If the estimated photometric value is not smaller than the threshold value, the signal charges of the main and subregions are read out independently of each other.

  • Patent number: 7218348
    Abstract: An object is to prevent a false signal from being generated. In a CCD comprising a lot of photodiodes, vertical transfer paths, and a horizontal transfer path, signal charges respectively representing R, G and B color components are mixed in the horizontal transfer path. Therefore, readout of the signal charges inputted to the horizontal transfer path from the photodiodes is controlled such that the order of the color components respectively represented by the signal charges is a repetition of R, G, B and G and a repetition of B, G, R and G in every other row. When complementary colors are generated by mixing pixels in the horizontal transfer path, they differ even in the same column, thereby making it possible to prevent a false signal from being generated.

  • Patent number: 7190403
    Abstract: A solid-state image pickup apparatus includes a timing signal generator for generating timing signals. Particular gates formed in each of photosensitive cells arranged in an image pickup section are driven independently or simultaneously in response to the timing signals. In an independent drive mode, outputs each having particular sensitivity are obtained from the different photosensitive regions of the individual cell by one time of exposure, covering a range of sensitivity as broad as one achievable with repeated photometry. This reduces the number of times of photometry for determining adequate exposure. In a simultaneous drive mode, outputs are produced in the usual manner. An exposure value calculator converts the resulting image signals to values having a predetermined format while an exposure parameter determining section determines exposure parameters if those values are adequate.

  • Patent number: 7148925
    Abstract: A solid-state image pickup apparatus includes a color filter including complementary color filter segments. When a shutter release bottom is pressed to its half-stroke or full-stroke position, light incident via the filter is picked up in a movie/photometry or a still picture mode, respectively. While signal charges are read out of an image sensor in accordance with the mode, the signal charges are digitized to become pixel data. In the movie/the photometry mode, despite that a plurality of pixel data are mixed together, a set of primary color pixel data are generated as if pixel signals were thinned out by mixture. In the still picture mode, all the pixels are sequentially read out and interpolated to generate primary color pixel data greater in number than photosensitive cells. The primary color data are raised in frequency to enhance the resolution of a picture.

    Abstract: Methods of detecting relative misalignment between a color filter array and a sensor array in a color sensor array. The present invention provides methods for detecting and compensating for shifts of one or more rows and/or columns between a color filter array and a sensor array that may occur during the color sensor array fabrication process. The present invention also enables the use of color sensor arrays in which the alignment of a color filter array relative to the corresponding sensor array is unknown. In one embodiment, a detectable pattern of one or more pixels (e.g., pixels having black filters) is introduced into the periphery of the color sensor array. The position of the pattern is detected and color image data are processed with respect to the detected position. The invention is very cost effective and enables the use of image sensors with misaligned color filter arrays just as if they were manufactured correctly.

This makes it possible to easily prevent the event in which the light collecting efficiency and sensitivity of each pixel vary between two adjacent pixel rows.

    Abstract: A solid-state imaging apparatus includes an image pick-up section in which photosensitive devices are arranged in, e.g., a honeycomb G square lattice, RB full-checker pattern due to shifted pixels. Regions void of the photosensitive devices are assumed to be virtual photosensitive devices. A signal processing section generates data for the virtual photosensitive devices by using the data of surrounding photosensitive devices while attaching importance to accurate color reproduction and horizontal and/or vertical resolution. As a result, the number of pixel data are increased in a square lattice arrangement. Therefore, high quality image signals are readily achievable with a smaller number of photosensitive devices than conventional with a conventional apparatus. Interpolation can be executed with the high quality signals to the limit of resolution with an adequate circuit scale.

  • Patent number: 6721005
    Abstract: A solid-state image sensor comprising an effective pixel area having light receiving portions which perform photoelectric conversion by taking in light and an optical black area which forms a reference black level without taking in light. The light receiving portions are formed inside electrode opening port portions which are formed through an electrode. Electrode opening port portions in the optical black area which are formed through the electrode are formed narrower than the electrode port portions in the effective pixel area. Alternatively, there may be no opening port portions formed in the optical black area.

  • Patent number: 6703597
    Abstract: A method of resolving photoelectron coupling that results from the operation of a staggered charge-coupled device inside a scanner. The staggered charge-coupled device at least includes an optical sensor group comprising of an optical sensor array and a neighboring optical sensor array for scanning pixels. The method includes the step of: recording the quantity of photoelectrons transferred between a first quantity of photoelectrons captured by the optical sensor array and a second quantity of photoelectrons captured by the neighboring optical sensor array during a scanning time interval t. Thereafter, the quantity of transferred photoelectrons is subtracted from the first quantity of photoelectrons captured by the optical sensor array to obtain the correct quantity of photoelectrons captured by the optical sensor array during the scanning time interval t. Using the corrected value, accurate brightness value of the pixels scanned by the optical sensor array is obtained.

  • Publication number: 20040021785
    Abstract: A closed circuit television surveillance system of the type used with a dome housing includes a camera which can be scanned with respect to pan and tilt axes. The camera is capable of scanning almost 180° about the tilt axis. As the camera passes the vertical position, the image scan of the camera is flipped electronically so that the image on the monitor appears right-side up even though the camera position has changed to up-side down after it passes the vertical position.
