We tested a new model of CMOS detector manufactured by the Gpixel Inc, forpotential space astronomical application. In laboratory, we obtain some biasimages under the typical application environment. In these bias images, clearrandom row noise pattern is observed. The row noise also contains somecharacteristic spatial frequencies. We quantitatively estimated the impact ofthis feature to photometric measurements, by making simulated images. Wecompared different bias noise types under strict parameter control. The resultshows the row noise will significantly deteriorate the photometric accuracy. Iteffectively increases the readout noise by a factor of 2 to 10. However, if itis properly removed, the image quality and photometric accuracy will besignificantly improved.
