Features

Video Image Formats

The Picolo series frame grabbers acquire color or monochrome video images from composted interlaced video signals. The NTSC, PAL and SECAM colour standards are supported. The monochrome video acquisition complies with the so-called CCIR (625 lines) and EIA RS-170 (525 lines) standards.

Acquisition of full frame (two fields) or single field images is selectable.

Acquisition

Before PCI transfer to the PC, the acquired images can be scaled to any format smaller than the original one, down to 1/12. The downscaling process involves a sophisticated hardware device, performing an accurate interpolation in both the horizontal and vertical direction. The image buffer for a downscaled image is smaller in size, and its transfer needs less PCI bandwidth.

Moreover, any part of the incoming image can be retained for further PCI transfer, allowing to define region of interest.

All desirable adjustments can be applied to the images during acquisition, such as video contrast, brightness, color saturation, and hue (NTSC only).

Synchronisation

A fully digital technique is used to synchronize the digitiser operation on the incoming video signal. This ensures a stable and robust operation despite the varying video conditions. 

A poor video signal issued by a low-end VCR is robustly supported. When using high-quality video surveillance cameras, the acquisition performance is exemplary, as demonstrated by a jitter figure in the nanosecond range.

Image fidelity

All precautions have been taken in the Picolo series to ensure an excellent fidelity of the grabbed bitmap in respect of the original video signal. IN particular, environmental conditions may induce common-mode noise in the signal issued by distant cameras. Picolo Pro 2 cards have special circuitry to remove this defect, and this is highly appreciated in video surveillance applications.

Bitmap image formats

Before storing the acquired images into the destination memory buffer, a pixel format conversion takes place in real-time. Numerous colour or monochrome formats can be chosen.

Bus mastering

All Picolo frame grabbers are PCI bus mastering agents that directly store the acquired images into the PC's physical memory without CPU involvement. As a unique feature, the Picolo series automatically recovers the scatter-gather virtual memory mapping to present the data as a regular bitmap image in a user allocated memory buffer.

Characteristics

Recommended operating conditions

Notes:

1. Vertical Sync pattern (equalisation pulses & serration pulses) must comply with PAL/NTSC standard.

2. SAR=SL_A/SL_B where SL_A is the amplitude of the sync tip of the video signal after switching and SLB is the amplitude of the sync tip of the video signal before switching.

3. Peak to peak amplitude of noise within the sync part of the video line measured with a low-pass filter of 20Mhz cut-off frequency.

Notes:

1. With worst case sync amplitude ratio.

2. Sync Amplitude threshold of "No Signal" error into MultiCam Driver.

3. Acquisition begins immediately after this delay.
