CAMERA_I2CEffect*

Syntax

#include <twl/camera.h>

CAMERAResult CAMERA_I2CEffect(CAMERASelect camera, CAMERAEffect effect);
CAMERAResult CAMERA_I2CEffectAsync(CAMERASelect camera, CAMERAEffect effect, CAMERACallback callback, void *arg);
CAMERAResult CAMERA_I2CEffectEx(CAMERASelect camera, CAMERAContext context, CAMERAEffect effect);
CAMERAResult CAMERA_I2CEffectExAsync(CAMERASelect camera, CAMERAContext context, CAMERAEffect effect, CAMERACallback callback, void *arg);

Arguments

camera Camera to configure (CAMERA_SELECT_IN, CAMERA_SELECT_OUT, or CAMERA_SELECT_BOTH).
context Context to change.
effect Effect 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

Changes the camera effects.

The CAMERA_I2CEffectEx function is used to change the setting with the context specified. The non-Ex functions change the setting for both context A and B. See CAMERAContext for information on contexts.

Unlike CAMERA_I2CEffect, the CAMERA_I2CEffectAsync function returns control immediately and runs asynchronously. Use callback to confirm that processing has completed.

Note: When specifying an effect with this function, you can vary the result of the effect by changing another setting at the same time.

  1. When CAMERA_EFFECT_NEGAFILM is specified, you can emphasize red tones by raising the color temperature of the white balance (CAMERA_WHITE_BALANCE_SHADE).
  2. When CAMERA_EFFECT_SEPIA is set, a soft impression can be obtained by lowering the sharpness setting.
