Abstract
An image sensor includes a first sensor pixel and a second sensor pixel that vertically overlap each other. The first sensor pixel includes a first signal generation circuit, and a first photoelectric converter that is connected to the first signal generation circuit and configured to generate first information from light having a first wavelength. The second sensor pixel includes a second signal generation circuit, and a second photoelectric converter that is connected to the second signal generation circuit and configured to generate second information from light having a second wavelength. A first horizontal surface area of the first photoelectric converter is different from a second horizontal surface area of the second photoelectric converter. An image sensor module includes the image sensor, a light source configured to emit light to a target object, and a dual band pass filter configured to selectively pass light reflected from the target object.
