Abstract
According to an embodiment, a data compression device includes a receiving unit, generating unit, a selecting unit, and a compressing unit. The receiving receives input data pieces. The generating unit generates starting point candidates representing the data having an error within a threshold value with respect to starting point data input at a first timing. The selecting unit refers to the starting point candidates, end point data input at a second timing, and intermediate data input at a timing in between the first timing and the second timing; and selects the starting point candidate which, as compared to the other candidates, has a greater number of pieces of the intermediate data approximated using the starting point candidate and using the end point data in such a way that the error is within the threshold value. The compressing unit outputs the selected starting point candidate and the end point data.
