# Image Settings Lock

Image Settings Lock is a feature that ensures brightness, contrast, zoom, and pan settings remain consistent across all frames in a sequence. This eliminates the need for annotators to repeatedly adjust image settings for each frame, improving efficiency and maintaining uniform visibility.

For example, if an annotator increases brightness in a dimly lit scene to better identify objects, this setting will persist as they move through frames, preventing visual inconsistencies. Without this feature, frequent adjustments would lead to inefficiencies and possible annotation errors.

## Benefits of Image Settings Lock

* **Consistency Across Frames** – Ensures uniform brightness, contrast, zoom, and pan settings across all images in a sequence, reducing discrepancies.
* **Reduced Cognitive Load** – Eliminates the need for users to manually adjust settings for each frame, allowing them to focus on annotation accuracy.
* **Improved Efficiency** – Saves time by maintaining preferred settings, preventing repetitive adjustments.
* **Enhanced Visibility** – Helps in better object detection by retaining optimal viewing conditions across all frames.
* **Minimized Errors** – Ensures annotations are made under consistent visual conditions, reducing misinterpretation caused by varying image settings.

## Steps to Use Image Settings Lock

{% step %}

#### Zoom and Pan Lock

* Resize the thumbnail to keep the image size optimal.
* Zoom and pan on the image sensor where the object is identified in the thumbnails.
  {% endstep %}

{% step %}

#### Brightness and Contrast Lock

* Switch to Annotate 2D mode.
* Using the brightness and contrast sliders, set them to the most optimal values.
  {% endstep %}
  {% endstepper %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.imerit.net/3d-multi-sensor-fusion/labeling/3d-multi-sensor-fusion-labeling-editor/key-features/image-settings-lock.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
