# CAMERA_I2CSharpness*

## Syntax

  `#include <twl/camera.h>`
  `CAMERAResult CAMERA_I2CSharpness(CAMERASelect camera, int sharpness);`
  `CAMERAResult CAMERA_I2CSharpnessAsync(CAMERASelect camera, int sharpness, CAMERACallback callback, void *arg);`

## Arguments

camera | Camera to configure (`CAMERA_SELECT_IN`, `CAMERA_SELECT_OUT`, or `CAMERA_SELECT_BOTH`).
sharpness | Sharpness to set.
callback | Function that is called when asynchronous processing has completed.
arg | Arguments when the callback function is invoked.

## Return Values

Returns `CAMERA_RESULT_SUCCESS` if configuration was successful.

## Description

Sets the camera's sharpness. The sharpness must be specified between -3 and 5.
Unlike `CAMERA_I2CSharpness`, the `CAMERA_I2CSharpnessAsync` function returns control immediately and runs asynchronously. Use callback to confirm that processing has completed.
