Abstract: A camera device includes an image sensor configured to capture an image, an object identifier configured to identify an object included in the captured image, a distance measurement device configured to determine a distance between the camera device and the identified object based on an occupancy percentage of the identified object in the captured image, and a controller configured to determine an optimal focus location where a reference value is the largest while moving a lens in a focus range corresponding to the determined distance between the camera device and the identified object, the focus range including at least a focus location of the lens.

Abstract: An image noise learning server includes an image input interface configured to receive training images, and at least one processor configured to control an image extractor to extract, from the training images, a first image including a stationary object and a second image including a moving object, a noise filter to obtain a third image by applying noise filtering with a first intensity to the second image, the third image including the moving object, a labeling unit to determine an intensity of a side effect based on a difference between the stationary object included in the first image and the moving object included in the third image, and a machine learning unit to receive, as a label, the determined intensity of the side effect and image attributes of the training images, and obtain artificial intelligence (AI) parameters by performing machine learning on the second image based on the received label.

Abstract: An image obtaining method employed by an image obtaining apparatus including a filter for reducing light of a first wavelength for focus control according to an embodiment of the inventive concept includes selecting a filter corresponding to a brightness of a photographing area from among one or more filters, wherein the one or more filters include a second filter that reduces light of the first wavelength; adjusting a focus based on light obtained from the photographing area to which the light of the first wavelength is irradiated; and obtaining an image using light obtained from the photographing area through a filter corresponding to the brightness.
