Abstract: A method of providing a stereoscopic image from a monocular image is provided. The method may include the steps of: (a) partitioning an original image; (b) generating a combination image by combining a partitioned image with the original image, and receiving input of specific image object marker information and input of background marker information on the combination image, where the specific image object marker information relates to a specific image object of which extraction is desired; (c) extracting a specific image object from the combination image; (d) performing defocusing by applying area processing on the combination image, in which the specific image object has been extracted, to adjust blurring; and (e) adjusting a depth value of the specific image object.

Abstract: Provided is a band-gap reference voltage generator for low-voltage operation and high precision. The band-gap reference voltage generator minimizes voltage drop by connecting resistors in parallel to bipolar transistors, and cancels temperature dependence by properly adjusting a resistor of an output stage, so that it can provide a stable reference voltage that is unaffected by a change in temperature in spite of a low power supply voltage. Further, the band-gap reference voltage generator minimizes variation of the reference voltage caused by offset noise by switching of input and output voltages at input and output stages of a feedback amplifier, so that it can provide a precise reference voltage.
