3.12 Available Video Formats, Modes and
Frame Rates on Monochrome Cameras
3.12.1 Standard Formats, Modes and Frame Rates
The following standard video formats, modes and frame rates are available on all
A102
f
monochrome cameras:
Format 2, Mode 2, FrameRate 3
( 1280 x 960, Y Mono, 8 bits/pixel, 15 fps )
Format 2, Mode 6, FrameRate 2
( 1280 x 960, Y Mono, 16 bits/pixel, 7.5 fps )
3.12.2 Customizable Formats and Modes
Format 7, Mode 0 is available on
A102
f
monochrome cameras.
Format 7, Mode 0
Format 7, Mode 0 is used to enable and set up the area of interest (AOI) feature described in
Section
3.6
. Format 7, Mode 0 is parameterized by using the Format 7, Mode 0 control and status
registers (see page
4-27
).
When the camera is operating in Format 7, Mode 0, the frame rate can be adjusted by setting the
number of bytes transmitted in each packet. The number of bytes per packet is set by the Bytes
Per Packet field of the Bytes Per Packet register.
The value that appears in the Max Bytes Per Packet field of the Packet Para Inquiry register will
show the maximum allowed bytes per packet setting given the current AOI settings. When the
bytes per packet is set to the maximum, the camera will transmit frames at its maximum specified
rate. By default, the AOI is set to use the full sensor area and the bytes per packet is set to 4096.
If you set the bytes per packet to a value lower than the maximum, the camera will transmit frames
at a lower rate. The rate is calculated by the formula:
L
When the camera is operating in Format 2, Mode 6, it outputs 16 bits per pixel but
only 12 bits are effective. The effective pixel data fills from the LSB and the unused
bits are filled with zeros. Pixel data is stored in the PC memory in little endian for-
mat, i.e., the low byte for each pixel is stored at the lower address and the high byte
is stored at the neighboring higher address.
