Grasshopper3 PGE Attributes

8.1

Pixel Formats

Pixel formats are an encoding scheme by which color or monochrome images are produced from raw image data.
Most pixel formats are numbered 8, 12, or 16 to represent the number of bits per pixel.
The Grasshopper3 PGE's
output (14- bit (10- and 12- bit GS3- PGE- 23S6)). If the pixel format selected has fewer bits per pixel than the
ADC output, the least significant bits are dropped. If the pixel format selected has greater bits per pixel than the
ADC output, the least significant bits are padded and can be discarded by the user.
8.1.1

Raw

Raw is a pixel format where image data is Bayer RAW untouched by any on board processing. Selecting a Raw
format bypasses the FPGA/color core, which may disable image processing, but allows for faster frame rates. In
a GenICam application, this is achieved using Image Format Control and disabling On Board Color Processing.
8.1.2

Mono

Mono is a pixel format where image data is monochrome. Color cameras using a mono format enable FPGA/color
core image processing such as access to gamma/LUT.
Y8 and Y16 are also monochrome formats with 8 and 16 bits per pixel respectively.
8.1.3

RGB

RGB is a color-encoding scheme that represents the intensities of red, green, and blue channels in each pixel.
Each color channel uses 8 bits of data. With 3 color channels, a single RGB pixel is 24 bits.
8.1.4

YUV

YUV is a color-encoding scheme that assigns both brightness (Y) and color (UV) values to each pixel. Each Y, U,
and V value comprises 8 bits of data. Data transmission can be in 24, 16, or 12 bits per pixel. For 16 and 12 bits per
pixel transmissions, the U and V values are shared between pixels to free bandwidth and possibly increase frame
rate.
YUV444 is considered a high resolution format which transmits 24 bits per pixel. Each Y, U, and V value has 8 bits.
YUV422 is considered a medium resolution format which transmits 16 bits per pixel. Each Y value has 8 bits, but
the U and V values are shared between 2 pixels. This reduces the bandwidth of an uncompressed video signal by
one-third with little to no visual difference.
