  The optical characteristics of the Kazakov-Solodukhin (KS) black hole (BH)
surrounded by a thin disk is investigated. By utilizing the ray-tracing
technique, we derive the the direct and secondary images to illustrate the
influence of observational inclination angle (\theta_{0}) and quantum
correction parameter (a) on the observable properties. Our calculation involves
determining the effective potential, light deflection, and azimuthal angle of
the BH, as well as the radiation flux of the accretion disk. By assuming three
function models, we determine that the exponential function is the most
suitable for describing the relationship between the observed flux and the
quantum deformation parameter. Our research reveals that the observable
characteristics of a BH are affected not only by the shape of the accretion
disk, but also by its spatiotemporal properties and the observer's inclination
angle. We observe that a BH encircled by an optically thick accretion disk
yields different results from those of an optically thin disk.
