データ送信装置、データ送受信システム及びデータ送信方法
Document Type and Number:
Japanese Patent JP6370263
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a data transmission device and the like, capable of securing transmission quality without increasing transmission speed in performing serial transmission on digital data obtained by imaging a subject.SOLUTION: A data transmission device includes: an imaging unit that performs A/D conversion on an analog signal obtained by an imaging element imaging a subject to create digital data showing a gradation value for each pixel of the imaging element; a data replacement unit that replaces a bit string showing a predetermined gradation value with a bit string that is not used for the imaging unit creating digital data using A/D conversion; a bit value inversion unit that performs bit value inversion processing of inverting a bit value included in digital data after replacement by the data replacement unit according to a predetermined inversion pattern and performs parallel output of digital data obtained by the bit value inversion processing; and a transmission unit that converts the digital data output in parallel from the bit value inversion unit to serial data and transmits the serial data.SELECTED DRAWING: Figure 1
