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 A102f

monochrome cameras:

Format_2, Mode_2, FrameRate_3 (Mono, 8 bits/pixel, 1280 x 960 pixels at 15 fps)

Format_2, Mode_6, FrameRate_2 (Mono, 16 bits/pixel, 1280 x 960 pixels at 7.5 fps)

3.12.2 Customizable Formats and Modes

Formet_7, Mode_0 is available on A102f 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 4-10).

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 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:

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.
