SENSOR SCAN MODE

(Applies only to 35X models.)

Sensor scan mode controls the internal processing of the camera's image sensor. The data scanned from the image sensor at each field time is used for the internal image control algorithms and digital signal processing (DSP).

Note: When changing from PROGRESSIVE to INTERLACED, or vice-versa, the camera restarts to establish the new setting.

There are two sensor scan modes:

PROGRESSIVE (default): Produces a higher quality image by using each line scanned from the image sensor.

INTERLACED: Produces a slight increase in sensitivity by using blended data from pairs of lines scanned from the image sensor.

When sensor scan mode is set to INTERLACED, the wide dynamic range and image enhancement features are automatically disabled. There may be additional effects, such as a degradation of the signal-to-noise ratio, degradation of the color reproduction, and a loss of motion detection for presets configured with motion detection.

FIELD ALIGN

(Applies only to 18X, 23X, and 35X models.)

Field align determines whether the camera produces progressive segmented frame output (PsF) or interlaced frame output. Analog video from the camera is always output in separate fields as required for compatibility. This feature allows PsF to be recombined by an encoding device without a time difference between fields, as is typically seen from interlaced analog video output. Enabling field align requires that the encoding device you are using always combines the odd and even fields in the specified order.

There are three field alignment settings:

OFF (default): Field alignment is disabled. Use this setting if you are using an analog device/ system or a digital encoder that does not support PsF.

ODD: Arranges the odd field for a particular video frame before the even field for that frame.

EVEN: Arranges the even field for a particular video frame before the odd field for that frame.

Notes:

If you enable field alignment by selecting ODD or EVEN, you must disable any deinterlacing settings for the encoding device to achieve maximum resolution.

The ODD and EVEN settings require that the sensor scan mode is set to PROGRESSIVE. If field align is set to ODD or EVEN, the sensor scan mode automatically changes to PROGRESSIVE.
