A PCB includes a plurality of layers spaced apart in a vertical direction, a first detection pattern and a second detection pattern and pads connected to the first detection pattern and the second detection pattern. The first detection pattern and the second detection pattern are provided in a respective one of a first layer and a second layer adjacent to each other such that the first detection pattern and the second detection pattern are opposed to each other. The pads are provided in an outmost layer. Each of the first detection pattern and the second detection includes at least one main segment extending in at least one of first and second horizontal directions and a diagonal direction. A time domain reflectometry connected to a pair of pads detects a misalignment of the PCB by measuring differential characteristic impedance of the first detection pattern and the second detection pattern.

Printed circuit boards and memory modules

A circuit board includes a first insulating layer; a first wiring pattern and a second wiring pattern each formed to be side to side with each other on an upper surface of the first insulating layer; a second insulating layer formed on the upper surface of the first insulating layer to cover the first and second wiring patterns; a third wiring pattern formed on an upper surface of the second insulating layer to overlap the first wiring pattern in a vertical direction; a fourth wiring pattern formed on the upper surface of the second insulating layer to overlap the second wiring pattern in the vertical direction; a first via passing through the second insulating layer and connecting the first and fourth wiring patterns; and a second via passing through the second insulating layer and connecting the second and third wiring patterns.

Circuit board and semiconductor module

An electronic device and an operating method thereof are disclosed according to embodiments. An electronic device according to an embodiment includes: a camera; a display; a communication interface; a memory for storing one or more instructions; and a processor that executes the one or more instructions stored in the memory, the processor being configured to: generate an event instructing to display one or more markers on a screen of a display device and transmit the event to the display device; control the camera to capture an image of at least a portion of a wall around the display device using the one or more markers displayed on the screen of the display device according to the generated event; generate a background image to be displayed on the screen of the display device based on the obtained image; and transmit the generated background image to the display device such that the generated background image is displayed on the screen of the display device.

Electronic device and operation method thereof

An electronic device and an operating method thereof are provided. The electronic device includes: a camera; a display; a communication interface; a memory storing one or more instructions; and a processor configured to execute the one or more instructions stored in the memory to: generate an event to instruct a plurality of markers to be displayed on a screen of a display apparatus and transmit the generated event to the display apparatus; determine, from among images obtained from the camera, an image from which at least a region of a wall surface in the vicinity of the display apparatus is to be extracted, via recognition of the plurality of markers displayed on the screen of the display apparatus in response to the generated event; extract, from the determined image, a region corresponding to a shape obtained based on the recognized plurality of markers; generate a background image to be displayed on the screen of the display apparatus, by correcting an image of the extracted region; and transmit the generated background image to the display apparatus so that the generated background image is displayed on the screen of the display apparatus.

Electronic device for generating a background image for a display apparatus and operation method thereof

An image processing method and a display apparatus therefor are provided. The display apparatus includes a display, a communicator that communicates with an external device; a memory storing one or more instructions; and a controller including a processor for executing the one or more instructions stored in the memory. The processor is configured to execute the one or more instructions to receive an image from the external device, obtain information about a first distance corresponding to a distance between a front surface of the display apparatus and a wall, and, when the image is displayed on the display, apply a shadow effect to one or more of sides of the image based on the information about the first distance.

Image processing method and display apparatus therefor providing shadow effect

A verification method for encrypter operation and an electronic voting verification system using the same, which can verify the operation of the encrypter without having to execute corresponding decryption. In the verification method, the encrypter creates a plurality of ciphertexts corresponding to the plain text and presenting the ciphertexts to a user. The user selects one of the ciphertexts, the encrypter dispenses a certificate where information used by the encrypter during encryption is recorded, in response to the ciphertexts which are not selected by the user; and the user creates a ciphertext in person and verifies whether or not the user-created ciphertext is identical with the user-selected ciphertext. Then, the user can verify the encryption results inside and outside a polling booth.
