DRAFT
3.13 Available Video Formats, Modes, and
Frame Rates on Color Cameras
3.13.1 Standard Formats, Modes, and Frame Rates
The following standard video formats, modes, and frame rates are available on A102fc color
cameras:
Format_2, Mode_0, FrameRate_2 (YUV 4:2:2, 16 bits/pixel ave., 1280 x 960 pixels at 7.5 fps)
Format_2, Mode_2, FrameRate_3 (Mono, 8 bits/pixel, 1280 x 960 pixels at 15 fps)
3.13.2 Customizable Formats and Modes
Format_7, Mode_0 and Format_7, Mode_1 are available on A102fc color 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 4-10).
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
BytePerPacket field of the Byte_Per_Packet control register.
The value that appears in the MaxBytePerPacket field of the Packet_Para_Inq control 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 4092.
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:
Keep in mind that when you lower the bytes per packet setting, the number of bytes needed to
transmit a frame (the packets per frame) will increase. Due to limitations in the DCAM structure,
a maximum of 4095 packets per frame is allowed. If you set the bytes per packet too low, the
number of packets per frame will exceed the 4095 packet limit and the camera will not transmit
frames properly.
L
When the A102fc is operating in Format_2, Mode_2 (Mono), it outputs the raw data for
each pixel, not the Y component as indicated in the DCAM specification. This is done
so that the
A102fc will have a standard output mode equivalent to the A101fc. This type
of output is sometimes called “Bayer 8.”
L
When the camera is operating in Format_7, the Cur_V_Frame_Rate control register is
not used and has no effect on camera operation.
