    Abstract: A calculation code generation circuit performs calibration using a counter, and a digital correction circuit including the same. The calculation code generation circuit performs a calculation process according to first and second modes, the calculation process including generating a first code by sampling a first value of the count code, generating a second code by sampling a second value of the count code, generating first and second calculation codes using the first and second codes in the first and second modes, respectively, and generating, in a calibration disable state, a third calculation code using the first and second calculation codes generated in the first and second modes, respectively, to remove the influence of the comparison offset or comparison performance of a comparator, thereby removing a calibration error.

    Abstract: An imaging lens system includes a first lens having a negative refractive power, a second lens having a refractive power, a third lens having a refractive power, a fourth lens having a refractive power, a fifth lens having a refractive power, and a sixth lens having a convex object-side surface is convex in a paraxial region thereof and a concave image-side surface in a paraxial region thereof. The first to sixth lenses are sequentially disposed in ascending numerical order along an optical axis of the imaging lens system from an object side of the imaging lens system toward an image plane of the imaging lens system, and one or more of the first to fifth lenses is configured to be movable in a direction of the optical axis.
