INSPECTION APPARATUS

PROBLEM TO BE SOLVED: To provide a data deviation correction device and a data deviation correction method for performing skew correction in a system configured by including a multi-channel transmission line.SOLUTION: Like an initial state, a signal of CH0(402a) arrives first, a signal of CH1(402b) arrives later and a signal of CH2(402c) arrives finally (1). Like first delay insertion, first delay synchronizing a rising edge of a data synchronizing signal STROBE and data of each channel is inserted but inserted to CH0 for a delay amount 410a, to CH1 for zero delay amount and to CH2 for a delay amount 410b (2). In order to correct deviation between a line synchronizing signal and data of each channel caused by adding first delay, as shown in second delay insertion, the time for receiving one item of channel data is set to line synchronizing signals LINE_VALID(400), CH0(402a) and CH1(402b) as a second delay amount, as needed (3).
