    Abstract: An image sensor includes a pixel array, a column signal processor, and a column mismatch compensator. The pixel array outputs a pixel signal from each column line during a pixel measuring time, and outputs a reference signal during a reference measuring time. The column signal processor performs correlated double sampling (CDS) on the reference signal to generate a reference CDS signal, and performs CDS on the pixel signal to generate a pixel CDS signal. The column mismatch compensator compensates the pixel CDS signal based on the reference CDS signal.

    Abstract: An electronic device includes a memory, a communication circuit, and a processor configured to operatively connect with the memory and the communication circuit. The processor is configured to send identification information of a base station attached to the electronic device via the communication circuit to a server, receive first base station information about base stations included in a first area on the base station from the server, store the first base station information in the memory, and estimate a location of the electronic device based on properties of a signal received from at least one of the base stations included in the first area or the first base station information.

    Abstract: Provided is an image processing apparatus. The image processing apparatus may determine whether a ray and a bounding volume including a primitive intersect each other, prior to determining whether the primitive and the ray intersect each other. An intersection test between the bounding volume and the ray may use a small amount of calculation compared to an intersection test between the primitive and the ray and thus, an amount of calculation used for rendering of the image processing apparatus may significantly decrease.

    Abstract: An image sensor includes multiple counters and a counter controller. Each counter of the multiple counters is configured to perform counting of a comparison result signal and to generate a count result, the comparison result signal being obtained by comparing a ramp signal and a pixel signal of a column of multiple columns. The counter controller is configured to generate and transmit a counter clock signal and (n−1) delay clock signals to the counters, respectively, “n” being a natural number equal to or greater than two. Each delay clock signal of the (n−1) delay clock signals is obtained by delaying the counter clock signal by a corresponding offset code.
