# image_sharpness

> Evaluates image sharpness

## Overview

Evaluates whether a still image is sufficiently sharp.

## Configuration

This detector does not accept configuration keys.

## Example Configuration

```json theme={null}
{
  "detector_name": "image_sharpness",
  "config": {}
}
```

## Result Schema

```json theme={null}
{
  "detector_name": "image_sharpness",
  "pass_check": true,
  "score": 0.78,
  "rationale": "Image appears sharp enough for large-format printing",
  "metrics": {
    "base_score": 31.2,
    "downscaled_score": 28.7,
    "crop_score": 27.4,
    "min_sharpness_score": 20.0,
    "min_downscaled_sharpness": 18.0,
    "upscaled_score": 24.5,
    "min_upscaled_sharpness": 22.0
  }
}
```

## Interpreting Results

* **base\_score/downscaled\_score/crop\_score**: Core sharpness measurements used for pass/fail.
* **min\_* thresholds*\*: The minimum scores required to pass.
* **upscaled\_score**: Included only when upscaling checks are enabled.
