SOI763A  
Color CMOS VGA Sensor (640x480)


General Description

The SOI763A CMOS image sensors are single-chip video/imaging camera devices designed to provide a high level of functionality in a single,small-footprint package.The devices incorporate a 640x480 image array capable of operating at up to 30 frames per second (fps).Proprietary sensor technology utilizes advanced algorithms to cancel Fixed Pattern Noise (FPN), eliminate smearing, and drastically reduce blooming.
All required camera functions including exposure control, gamma, gain, white balance, color matrix, color saturation, hue control, windowing, and more, are programmable through OmniVision's Serial Camera Control Bus (SCCB) interface. The device can be programmed to provide image output in different 8-bit formats.

Features

  • 326,688 pixels, 1/4" lens, VGA / QVGA format
  • Interlaced or Progressive scan modes
  • 8-bit Data output formats:
    - YCbCr 4:2:2 ITU-656
    - RGB 4:2:2
    - RGB Raw Data
  • Wide dynamic range, anti-blooming, zero smearing
  • Electronic exposure / gain / white balance control
  • Image quality controls:
    - Brightness, contrast, gamma, saturation, sharpness, windowing, hue, etc.
  • Internal and external synchronization
  • Line exposure option
  • 3.3-Volt operation, low power dissipation
    - <25mA active power at 30 fps
    - <10μA in power-down mode
  • Built-in Gamma correction (0.45/0.55/1.00)
    SCCB programmable:
    - Color saturation, brightness, hue, white balance, exposure time, gain, etc.
