Abstract: A surveillance camera and a control method for the surveillance camera are disclosed. The present disclosure makes it possible to determine whether at least one of a bounding box for a head region of an objected detected from a side view image and a bounding box for an entire body region thereof intersects a preset counting line, thereby counting people passing through the counting line. In the present disclosure, one or more of a surveillance camera, an autonomous vehicle, a user terminal, and a server may be linked to an artificial intelligence module, a robot, an augmented reality (AR) device, a virtual reality (VT) device, and a 5G service.

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.

Abstract: A method, performed by an image processing device, of encrypting image data includes: selecting an encryption target unit from among a plurality units constituting an image; generating a table including identification information about the encryption target unit; generating a first encryption unit including data obtained by encrypting the encryption target unit; generating a second encryption unit including data obtained by encrypting the table; and generating a bitstream including the first encryption unit, the second encryption unit, and units other than the encryption target unit among the plurality of units constituting the image.

Abstract: An encoding/decoding device according to the present invention derives a residual coefficient of a residual block from a bitstream, calculates a quantization parameter for the residual block, performs inverse quantization on the residual coefficient by using the quantization parameter, and performs inverse conversion on the inversely quantized residual coefficient, thereby enabling restoration of a residual sample of the residual block.

Abstract: Provided is an image display system displaying an image obtained from an image capturing device. A method of operating a terminal in the image display system includes displaying a first user interface (UI) screen including the image through a display, obtaining a first user input indicating a pointing position in the image, generating a first enlarged image of an enlargement target area corresponding to the pointing position, in response to the first user input, and displaying a second UI screen including the first enlarged image through the display, wherein an input time of the first user input is greater than or equal to a preset threshold time.
