Provided is an image sensor including a sensor array including a plurality of pixels arranged in rows and columns. The image sensor may include a ramp signal generator which may generate a ramp signal. The intensity of the ramp signal may increase or decrease in response to a ramp enable signal. The image sensor may include an analog-digital converter electrically connected to one of the columns of the pixels. The analog-digital converter may be configured to compare an output signal from the one of the columns of the pixels with the ramp signal, thereby generating time information. The analog-digital converter may be configured to convert the time information to digital information in response to a counter enable signal. An activation of the counter enable signal may be delayed by a predetermined time delay, compared with that of the ramp enable signal.

Image sensor and method of controlling the same

The signal compensating method includes receiving sensing signals from an image sensor pixel array; converting the sensing signals into digital signals using a plurality of analog-to-digital converters, respectively; and compensating the digital signals using offset values corresponding to the plurality of analog-to-digital converters, respectively.

Image capture device and signal compensating method of image capture device

In one embodiment, the modulator in an analog-to-digital converter includes a first reset switch and second reset switch, each controlled by a reset signal. The first reset switch is connected in a first reset feedback path between an input and an output of an integrator stage, and the second reset switch connected in a second reset feedback path between the input and the output of the integrator stage.
