Abstract: A progressive differential motion JPEG codec is disclosed. The compression encoder of the progressive differential motion JPEG codec comprises a video capture unit, a video capture buffer, a detection unit, a compression unit, and a quality level buffer. The video capture unit is used for receiving an image data and dividing a component of the image data into a plurality of image data blocks. The video capture buffer stores the image data block. The detection unit is electrically coupled to the video capture unit and the video capture buffer for detecting whether a content of the image data block input from the video capture unit is different from a content of the image data block retrieved from the video capture buffer.

Abstract: An apparatus and method for data capture with multi-threshold decision technique is disclosed. An apparatus for data capture with multi-threshold decision technique comprises a capture engine unit being operative to captures data from a video source, a buffer unit being operative to store the captured data by the capture engine unit, and a comparison unit being operative to compare the captured data stored in the buffer unit with a newly captured data outputted from the capture engine unit, wherein the comparison unit utilizes different thresholds to distinguish the difference degree between the captured data stored in the buffer unit and a newly captured data outputted from the capture engine unit so as to determine whether performing data update or not.
