  • Patent number: 7864216
    Abstract: A self-contained wireless camera (10) and a wireless camera system (25) having such a device and a base station (20). Video processing (e.g. video compression) circuitry (200, 210) of the camera device receives video signals from a camera (130) and provides processed video signals. These are transmitted over a shared radio channel. A radio receiver (101) receives processed (e.g. compressed) video signals from the base station or another camera device. Images from the camera or the base station are displayed in a selected manner on a display or monitor (140). The base station device (20) receives processed (e.g. compressed) video signals, stores them and retransmits them. A command signal is received by the radio receiver to modify operation in such a manner as to control bandwidth usage. Wireless camera devices can adjust their operation to accommodate other wireless camera devices.

  • Patent number: 7630001
    Abstract: An image shooting unit 21 generates an image signal DVb having an image shooting frame rate. A main line image processing block 40 performs frame addition on the image signal DVb having the image shooting frame rate, and generates a main line image signal having a desired output frame rate. Based on the image signal DVb, a monitor image processing block 50 generates a monitor image signal having a frame rate independent of the frame rate of the main line image signal. Since the frame rate of the main line image signal and that of the monitor image signal are independent of each other, shooting an image while varying the frame rate of the main line image signal allows a monitor image at an image shooting time to be displayed at a predetermined frame rate using the monitor image signal DVr.

  • Patent number: 7630000
    Abstract: An electronic blurring correction apparatus in the present invention includes a solid-state image-capturing device, which has an image-capturing section with photodiodes and vertical transfer CCD and an accumulation section with a vertical transfer CCD and a horizontal transfer CCD, wherein a first image transferred from the image-capturing section is accumulated in the vertical transfer CCD, relative blurring between the first image and a second image which is already accumulated in the horizontal transfer CCD is corrected by shifting the first image within the vertical transfer CCD and shifting the second image within the horizontal transfer CCD, and thereafter a composite image, which is obtained by combining the first image and the second image, is accumulated as a new second image in the horizontal transfer CCD.

  • Patent number: 7619672
    Abstract: A retrograde well structure for a CMOS imager that improves the quantum efficiency and signal-to-noise ratio of the imager. The retrograde well comprises a doped region with a vertically graded dopant concentration that is lowest at the substrate surface, and highest at the bottom of the well. A single retrograde well may have a single pixel sensor cell, multiple pixel sensor cells, or even an entire array of pixel sensor cells formed therein. The highly concentrated region at the bottom of the retrograde well repels signal carriers from the photosensor so that they are not lost to the substrate, and prevents noise carriers from the substrate from diffusing up into the photosensor. Also disclosed are methods for forming the retrograde well.

  • Patent number: 7616240
    Abstract: Electronic data output from CCD is separated into a brightness component Y and color difference components Cb and Cr and an edge is extracted for each of the components. The edge amounts are calculated from the extracted edges and the component having the maximum edge amount is selected. Edge information (for example, edge gradient direction) is calculated based on the selected component having the maximum edge amount, a filter is selected based on the calculated edge information about the component having the maximum edge amount, and smoothing processing is performed for the electronic data output from the CCD based on the filter. The electronic data subjected to the smoothing processing is written into flash memory.

  • 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: 7609319
    Abstract: A photography device has an AF mechanism including: a CCD; an analog signal processing section; an image input controller; an AF processing section; a CPU; and a focusing lens driving section. The AF mechanism operates to focus an imaging lens on a subject. If an image represented by output from the CCD does not include a specific low contrast subject, image data representing the image is passed through a first high frequency filter that transmits components having frequencies greater than or equal to a first cutoff frequency, and a focus evaluation value is determined based on the transmitted components. If the image includes the specific subject, the image data is passed through a second high frequency filter that transmits components having frequencies greater than or equal to a second cutoff frequency, lower than the first cutoff frequency, and a focus evaluation value is determined based on the transmitted components.
