DRAFT
3.13.2 Customizable Formats and Modes
Format_7, Mode_0 and Format_7, Mode_1 are available on A601fc and A602fc color cameras.
Format_7, Mode_0
Format_7, Mode_0 is available on A601fc and A602fc color cameras. This mode 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 4-11).
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 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.
Color Codings
In Format_7, Mode_0, the Mono 8, Raw 8, Raw 16, and YUV 4:2:2 color codings are available.
When the
Mono 8 ID is set in the Color_Coding_ID field of the Format_7, Mode_0 register, the
camera outputs 8 bits per pixel and outputs only the Y component (brightness) of the YUV format.
When the
Raw 8 ID is set in the Color_Coding_ID field of the Format_7, Mode_0 register, the
camera outputs 8 bits per pixel and outputs the raw data for each pixel. The pixel data is not
processed to account for the color filter. (This type of output is sometimes called “Bayer 8.”)
When the
Raw 16 ID is set in the Color_Coding_ID field of the Format_7, Mode_0 register, the
camera outputs 16 bits per pixel but only 10 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 format, 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. The camera outputs raw data for each pixel. The pixel
data is not processed to account for the color filter.
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.
