    Abstract: A camera module includes a compressor configured to divide a plurality of pixels included in image data, into a plurality of pixel groups, with respect to each of the plurality of pixel groups into which the plurality of pixels is divided, calculate a representative pixel value of a corresponding pixel group, based on pixel values of multiple pixels included in the corresponding pixel group, generate first compressed data, based on the calculated representative pixel value of each of the plurality of pixel groups, with respect to each of the plurality of pixel groups into which the plurality of pixels is divided, calculate residual values representing differences between the pixel values of the multiple pixels included in the corresponding pixel group and the representative pixel value of the corresponding pixel group, and generate second compressed data, based on the calculated residual values of each of the plurality of pixel groups.

    Abstract: An image encoding apparatus includes a compressor that generates a bitstream including encoded data corresponding to values of original pixels, based on one of encoding modes, and a reconstructor that generates values of reference pixels by reconstructing the bitstream. In a first mode of the encoding modes, the compressor generates the bitstream based on a difference value between each of the values of the original pixels and a reference value which is based on at least one of the values of the reference pixels. In a second mode of the encoding modes, the compressor generates the bitstream based on an average value of at least two of the values of the original pixels.

    IPC: H04N5/367

    Abstract: Processing circuitry may be configured to detect an abnormal pixel among a plurality of pixels based on pixel values of the plurality of pixels and one or more reference pixel values corresponding to the plurality of values; generate first encoded data by encoding pixel data of the plurality of pixels based on the pixel values with a first encoder; generate second encoded data by encoding the pixel data based on remaining pixels of the plurality of pixels excluding the detected abnormal pixel with a second encoder; and output the first encoded data or the second encoded data based on detecting the abnormal pixel.

    Abstract: Disclosed is a near-field communication (NFC) system that includes an NFC supporting apparatus. The NFC supporting apparatus includes a dual coil and a first switch. The dual coil includes an NFC band coil and a radio frequency (RF) band coil. An RF amplitude modulation signal is generated at the RF band coil in response to a transmission from an implantable device. The first switch is configured to switch the NFC band coil based on the RF amplitude modulation signal. The NFC band coil is configured to generate an NFC amplitude modulation signal at an NFC band coil of an NFC reader in response to the first switch.
