Abstract: Disclosed is an image sensor. The image sensor includes an active pixel sensor array including first to fourth pixel units sequentially arranged in a column direction, and each of the first to fourth pixel units is composed of a plurality of pixels. A first pixel group including the first and second pixel units is connected to a first column line, and a second pixel group including the third pixel unit and the fourth pixel unit is connected to a second column line. The image sensor includes a correlated double sampling circuit including first and second correlated double samplers and configured to convert a first sense voltage sensed from a selected pixel of the first pixel group and a second sense voltage sensed from a selected pixel of the second pixel group into a first correlated double sampling signal and a second correlated double sampling signal, respectively.

Abstract: An electronic apparatus and a method of controlling the same are provided. The electronic apparatus includes a communication interface and a processor configured to receive multimedia data from an external apparatus, obtain a first finger print of first frames among a plurality of frames included in the multimedia data, the first frames being included in a first time interval, and transmit the first finger print to the server; identify whether a content in the multimedia data has been changed and a time point indicating a time of identifying a change in the content; based on identifying that the content has been changed, obtain a second finger print of a frame corresponding to the time point, and transmit the second finger print to the server; receive content information corresponding to the second finger print, and determine whether to change the first time interval based on the content information.
