FAQ

• Q: What are the conditions for Quick Zoom operation?
  • A: Quick zoom operates under conditions such as using presets, Wise auto focus, or Focus scan.
• Q: How can I adjust object size for Wise auto focus?
  • A: Object size adjustment for Wise auto focus can be done by modifying the sensitivity of object detection and the minimum/maximum object size in the settings.

Functions

Quick zoom

• The Quick zoom function enables the camera to move quickly to a specific focus or zoom position.
• Previously, a zoom tracking method was used which slowly moves the zoom area while trying to stay in focus. Quick zoom quickly zooms the camera to an area, then performs an auto focus function.
• Because the zoom or focus moves quickly to a specific position, the screen may become blurry during the Quick zoom (less than a second).

Quick zoom only operates under the following conditions:

• When the user saves the focus position to [Preset] or [Focus scan]
• When the [Wise auto focus] function is available

Preset

• Presets store not only Pan/Tilt/Zoom positions, but also focus settings.
• In addition to Presets, you can also run Swing/Group/Tour and other preset-based functions to quickly auto-focus after a quick zoom with stored focus settings.

Wise auto focus

• Wise auto focus performs a fast focus using an AI engine that calculates information based on human faces.
• That is, auto-focus works based on the human faces detected in the camera’s field of view.

Focus scan

• Focus scan is a function that allows a user to partition a selected area within the camera’s field of view into split zones then automatically scans and stores the focus for each split zone.
• Later, when the camera moves to that area, it will quickly auto-focus based on the stored information.

1. [Step 1. Focus scanning]
   • Focus scan moves to a specified area, divided according to the number of split zones you set, performs auto-focus, and stores the information.
   • It takes up to 12 seconds to store the focus of one split zone.
2. [Step 2. After scan completed]
   • Focus scan focuses using the stored value when the specified area includes a split zone with the stored focus information.
   • If there are two or more split zones in the specified area, it focuses with the information of the split zone that currently occupies the largest area in the video.

NOTE

In situations where Auto-focus malfunctions due to the false detection of objects, you can enable only Wise quick zoom for your convenience.

• A. Auto-focus based on recognized face
• B. Quick zoom based on recognized face

Precise compensation

Precise compensation can be used to compensate for errors caused by variations in the size of human faces, so you can adjust the value to be larger if the human face is larger than the typical size seen where the camera is installed, and vice versa.

• Default: 18

Object size adjustment

• The face detection rate and size used for Wise auto focus can be changed by adjusting the sensitivity of object detection and the minimum/maximum object size to suit your environment.

Note

• Increasing the sensitivity or decreasing the minimum size allows for more distant faces to be detected, but may result in a higher rate of false detection.

Using Wise auto focus

• Using Wise quick zoom & Wise auto focus
  • If you A specify an area for Area zoom where a face is detected, (Wise) Quick zoom & Wise focus are triggered to quickly B move to that area.

NOTE:

• Wise quick zoom works the same as Quick zoom works, but under different conditions; that is, the only difference is in the conditions.

Focus scan

Focus scan Settings

[Setup] → [Video & Audio] → [Focus scan]

1. Select the Enable focus scan checkbox.
2. Drag to specify the zone you want for Focus scan. Enter a name for the zone and set the split value. The number of split zones into which an area can be divided depends on the zoom value applied to the specified area. The more split zones that are stored, the more accurate auto-focus you can expect.

   • (By default, all zones are selected.)
4. If you choose Select all, it will select all zones.
   • (The selected zones will be shown in blue)
5. Click the button to start scanning. If you want to stop scanning, click the [Cancel] button.
6. In the pop-up window that opens when you click [Cancel], clicking [OK] will stop scanning after saving the zones scanned so far, and clicking [Cancel] will reset the zone settings.
7. “Focus scanning” is displayed while the scan is in progress as an on-screen display at the top left of the video, and “Focus scanning Complete” is displayed when the scan is complete.

• Editing the focus-scanned zone
  Select the zone you want to edit. The selected zone is displayed in a green box in the preview screen with 1x zoom applied.

  • [Auto scan]: Scans the enabled split zones of the selected zone again.
  • [Delete]: Deletes the selected zone.
  • [Edit]: Allows you to edit the detailed split zones of the selected zone manually.

• Editing the detailed split zones manually

Performance limitations of Quick zoom & Focus

Performance limitations of Wise auto focus

It may be out of focus or auto-focus may take longer in the following cases.

• Object detection results are inconsistent in size
• Children’s faces, small faces, or large faces
• Falsely recognizing an object which is smaller or larger than an actual person as a person
• Falsely detecting something that is not a person as a person
• The object is moving at a high speed
• The object is wearing a hat, or has longer or shorter hair than a normal person

Performance limitations of Wise quick zoom

Since the face must be within 72% of the area drawn with the Area zoom, Wise quick zoom may not work if you specify an area for Area zoom with no margin on the top or bottom of the face, as shown in the malfunctioning examples below.

Correct Example(O)

Incorrect Example 1 (X)

Incorrect Example 2 (X)

Limitations when setting up Focus scan

If you set the focus-scanned zone when the camera is at a certain tilt angle (90° to 70°, 0° to -20°), Auto-focus may not work because the split zone displayed on the screen does not match the actual split zone where the focus information will be stored.

Recommended tilt angle range when setting up Focus scan: 70° to 0°

Limitations when using Focus scan

• If the area ratio of the split zone where the focus is stored in the specified area is smaller than the recommended threshold (25% or less based on Tele), Focus scan may not work.

Info

• If the area ratio of one split zone within an area is not large enough, you may not be able to utilize the focus settings for that split zone.
