Embodiments of the disclosed technology relate to a memory system, a memory controller, and an operation method of the memory system. Based on embodiments of the disclosed technology, the memory system may suspend a target operation, which is a program operation or an erase operation, based on whether or not to execute a first operation of resetting a reference read bias when a failure occurs in a read operation executed after the target operation is suspended, and a number of times the target operation is suspended. Accordingly, the memory system is capable of preventing a problem in that the end time of a program operation or an erase operation is excessively delayed, and controlling the number of times a program operation or an erase operation is suspended.

An apparatus for estimating a camera pose according to an embodiment of the present disclosure includes a similar image searcher, a clusterer, and an estimator. The similar image searcher searches for a plurality of images similar to an input image, from among a plurality of previously-stored images, based on the input image. The clusterer creates a cluster including at least some similar images meeting predetermined conditions, from among the plurality of similar images, based on viewpoint data tagged to each of the plurality of similar images. The estimator estimates a pose of a camera that has generated the input image, based on the cluster.
