Abstract:
1. A digital photography device, comprising: a sensor implementing a rolling shutter timing mechanism; a shutter including a material having an alterable translucent state, wherein the shutter has a gradual transition curve from a first translucent state to a second translucent state and the shutter is in the optical path of light going to the sensor; a flash to generate a pulsed illumination, the alterable translucent state of the shutter to control the sensor's exposure to the photographic effects of ambient light during a picture using the pulsed illumination; and logic to detect a pressing of an actuator that triggers the flash, wherein the logic to synch up a changing amount of light being allowed to pass through the shutter having the alterable translucent states during the gradual transitioning of the shutter from the first translucent state to the second translucent state with an operation of the rolling shutter and a time period when the pulsed illumination occurs.
