2.1.2 Reference for C-MOS Imager Performance
Reference of the C-MOS imager performances below for the DT-X5M30E, DT-X5M30R and DT-X5M30U is
provided as a guide to be utilized by the user. The user can refer to these reference values in the table for his or her
specific business application. All the reference values have been came out from the assessment tests carried out
under the basic performance conditions below. However, it does not necessarily imply that the values are
guaranteed and optimum to any kind of business applications. They are intended for use by the user as a reference
only.
