Abstract: An image sensor includes a pixel array including first to third pixel groups, including first to third color pixels having first to third colors and outputting first to third pixel signal for the first to third colors, and an image signal processor receiving the first to third pixel signals, wherein the image signal processor, when the first pixel signal is a bad pixel signal, performs bad pixel correction on the first pixel signal based on the second pixel signal and the third pixel signal and generates a remosaiced pixel signal for the first through third colors by remosaicing the second and third pixel signals based on each other, and the corrected pixel signal and the remosaiced pixel signal represent information in which the first through third color pixels are rearranged in a second pattern having a higher frequency than a frequency of a first pattern.

Abstract: A photoacoustic and ultrasonic imaging device includes a laser light source configured to generate a laser, an ultrasonic wave source configured to generate an ultrasonic wave generation signal, an imaging probe including a laser emitter configured to receive the laser and emit the laser to a target and an ultrasonic transducer configured to receive the ultrasonic wave generation signal, emit an ultrasonic wave to the target, and detect a photoacoustic signal and an ultrasonic signal generated and reflected from the target, and an operation unit configured to form an image of tissue in the target from the laser and an image of the tissue in the target from the ultrasonic wave on the basis of the photoacoustic signal and the ultrasonic signal detected by the ultrasonic transducer.
