The garment includes a plurality of sensors that are in operable communication with each other for detecting position data of each sensor of the plurality of sensors relative to each other and at least one chip that is in operable communication with at least one of the sensors of the plurality of sensors and configured to collect the detected position data and generate an image of a body portion of a user of the garment based on the detected position data and communicate the generated image to at least one display device for displaying the generated image.

An adjustment value holding unit holds an adjustment value selected for displaying medical image data on a medical image display device with a predetermined image quality. An image attribute detector detects an attribute of the medical image data. A determiner determines whether or not the adjustment value held in the adjustment value holding unit matches an adjustment value corresponding to the attribute detected by the image attribute detector. A notification unit visually or audibly notifies that the adjustment value held in the adjustment value holding unit does not match the adjustment value suitable for the medical image to be displayed on the medical image display device, when the determiner determines that the adjustment value held in the adjustment value holding unit does not match the adjustment value corresponding to the attribute detected by the image attribute detector.

An electronic apparatus includes a memory storing instructions and a processor configured to execute the instructions to identify a display environment of an image, correct characteristics of a test image provided to identify a user's visual perception for characteristics of the image to correspond to the identified display environment, display the test image having the corrected characteristics on a display, and correct the characteristics of the image based on the user's adjustment input for the characteristics of the displayed test image.

In an embodiment according to the present disclosure, disclosed is an electronic device including a display, a first housing, a second housing at least partially overlapping and being movable with respect to the first housing, a first conductive region formed or disposed inside the first housing, and a second conductive region formed or disposed inside the second housing so as to at least partially overlap with the first conductive region when the first housing is moved with respect to the first housing, a display in which at least the first region is exposed to the outside of an electronic device through a front surface of the electronic device, and at least one processor in which, when the electronic device is switched from the first state to the second state, a second region extending from the first region of the display is withdrawn from the inside of the first housing and exposed to the outside of the electronic device along with the first region and, when the electronic device is switched from the second state to the first state, is introduced into the inside of the first housing and operatively connected to the display.
