Abstract: An image sensor includes a dual conversion gain pixel to output a high conversion gain signal according to a high conversion gain and output a low conversion gain signal according to a low conversion gain, by adjusting a conversion gain; a scaler to scale a voltage level of the high conversion gain signal; a ramp generator to generate a first ramp signal and a second ramp signal, slopes of the first and second ramp signals being different from each other; a comparator to compare the scaled high conversion gain signal and the first ramp signal to output a first comparison result, and compare the low conversion gain signal and the second ramp signal to output a second comparison result; and a counter to output a first counting result value based on the first comparison result and output a second counting result value based on the second comparison result.

Abstract: Disclosed is a multi-display apparatus including display modules and a sensor. Some of the display modules sequentially connected receive a signal from the sensor, and each of the display modules transmits signals including the signal from the sensor to a display module connected to a rear stage thereof. The display module connected to a final stage transmits the signal from the sensor to a control box. The control box includes a detector configured to detect whether signals from a plurality of transmission lines include a generated flag signal based on the signals including a signal from the sensor and a selector configured to select a transmission line detected as including the flag signal by the detector and set the selected transmission line as a channel for communication with the sensor.

Abstract: A multi-display device is configured to display an image, and the multi-display device includes display modules sequentially connected according to a prescribed connection configuration. Each of the display modules may include a signal input unit for acquiring an image signal and control information and a partial image selection unit for obtaining, from the control information, information about the connection configuration of the display modules, wherein each display module selects a partial image corresponding to the display module, from the image signal by referring to a first lookup table based on the information about the connection configuration.

Abstract: Disclosed are an electronic device and a method for controlling the electronic device. Specifically, the electronic device according to the present disclosure receives a first image signal and a second image signal which are separated from an original image signal through a first channel and a second channel having different frequency bandwidths, and which have different data rates. When the first image signal and the second image signal are received, the electronic device determines whether an error exists in the second image signal, obtains a first output image signal and a second output image signal on the basis of the first image signal and the second image signal according to a result of the determination, and outputs the obtained first output image signal or second output image signal.
