Abstract: Provided are an apparatus and method of converting a digital image signal, which is obtained through an image sensor comprising a plurality of pixels that are arranged in a matrix, into an analog image signal in order to transmit the analog image signal to a monitor device that outputs an image complying with a national television system committee (NTSC) standard or a phase-alternating line (PAL) standard. The method includes: generating a sample frequency based on the number of horizontal pixels of the digital image signal to comply with a horizontal scan period of the NTSC standard or the PAL standard; and converting image data of the horizontal pixels of the digital image signal into the analog image signal, according to the sample frequency.

Abstract: An image capturing device includes a lens, a lens driver configured to change a focus position by moving the lens, an image sensor configured to detect light passed through the lens, and a focus controller configured to control, based on an image generated by the image sensor, the lens driver to adjust the focus position. The focus controller is further configured to: monitor a feature change of a saturated object having an intensity greater than or equal to a threshold value, in each of a plurality of regions of an image, by adjusting the focus position; and adjust the focus position based on a trend of the feature change of the saturated object while the focus position is changed in a direction.
