Abstract
An image sensor is widely used in many fields, including the medical field and the security device field. Specifically, the image sensor is most widely used in digital cameras and mobile phones. The digital camera and the mobile phone require capturing images of higher resolution and higher quality. However, a preview size of the mobile phone or digital camera should be small because of a display limitation. Therefore, a function for reducing an image size or magnifying a specific portion of the picture is essential in the image sensor. Accordingly, there is provided an image sensor with a scaler. The image sensor with the scaler can arbitrarily adjust a size of an image without any additional scaling chip.
