Moving taking picture of stationary Moving taking picture Stationary with moving car of stationary 1. Were the images blurry in the case where you 2. Were the images blurry in the case where you 3. Discuss the concept of camera exposure time in 4. Digital cameras typically utilize either optical were stationary and subject was moving? were moving and subject was stationary? the context of motion imaging image stabilization or electronic image stabilization. Discuss each technology. What are the advantages and disadvantages of each approach?Explanation / Answer
1. when the camera is stationery and the object is moving we dont have blurry images but when the camera is moving and the object is stationary, we have blurry images
2. hence,the images are blurry in this case
3. when there is light coming form an object being used for capturing animage in the camera, due to less light the details of the imag ein the camera might remain unclear. So, by increasing exposure time, the lightdata form the real object is impinging on the sensor for the longer time, giving the digital interface within to have more time to process the input data and proicess it into an image with more details using the fact that there is more light illuminating the sensor from the image this time
4. Optical image stabilisation : the sensor / the lens is moved to compensate for the motion of the camera using complex arrays of motors and sensors like gyroscopes and accelerometers
Electronic Image stabilisation : This technique shifts the electronic image from frame to frame of video, enough to counteract the motion. It uses pixels outside the border of the visible frame to provide a buffer for the motion. This technique reduces distracting vibrations from videos by smoothing the transition from one frame to another. This technique does not affect the noise level of the image, except in the extreme borders when the image is extrapolated. It cannot do anything about existing motion blur, which may result in an image seemingly losing focus as motion is compensated
hence optical image stabilisation cannot compensate for too much rigrous motion but gives clearer images for motion under a limit
