7.5.2 Field Output Modes
On acA750 cameras, four "field output modes" are available: field 0, field 1, concatenated new
fields, and deinterlaced new fields.
Field 0 Output Mode: Each time the camera receives a frame trigger signal, it acquires, reads out,
and transmits a frame using the field 0 scheme described in Section 7.5.1 on page 109. Because
pairs of rows are combined, the transmitted image is commonly referred to as "half height", i.e., the
number of vertical pixels in the transmitted image will be one half of the number of physical pixels
in the sensor.
In Field 0 output mode, the pixel data from field 0 is considered to be a frame. Each time the camera
receives a frame trigger signal, it will acquire field 0 and will transmit the field 0 pixel data as a frame.
Field 1 Output Mode: Each time the camera receives a frame trigger signal, it acquires, reads out,
and transmits a frame using the field 1 scheme described in Section 7.5.1 on page 109. Because
pairs of rows are combined, the transmitted image is commonly referred to as "half height", i.e., the
number of vertical pixels in the transmitted image will be one half of the number of physical pixels
in the sensor.
In Field 1 output mode, the pixel data from field 1 is considered to be a frame. Each time the camera
receives a frame trigger signal, it will acquire field 1 and will transmit the field 1 pixel data as a frame.
