By a News Reporter-Staff News Editor at Electronics Newsweekly -- According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventor Choi, Hak-hun (Suwon-si, KR), filed on August 11, 2015, was published online on September 26, 2017.

The assignee for this patent, patent number 9774821, is SAMSUNG ELECTRONICS CO., LTD. (Suwon-Si, KR).

Reporters obtained the following quote from the background information supplied by the inventors: "Apparatuses and methods consistent with exemplary embodiments relate to a display apparatus and a control method thereof, and more particularly, to a display apparatus which converts a frame rate and a control method thereof.

"With the development of electronic technology, various electronic products have been developed and become increasingly popular. In particular, various display apparatuses, such as a television (TV), a portable phone, a personal computer (PC), a laptop PC, or a personal digital assistant (PDA) have been increasingly used in homes.

"As display apparatuses have become more widespread, users desire additional versatile functions. As manufacturers strive to meet the user demand, products having new functions are emerging one after another.

"Thus, functions performed in the display apparatuses have become increasingly diversified. In particular, in recent years, many display apparatuses while reproducing moving images perform frame rate conversion, process motion to be smoother, and display a smoother image with a converted frame rate.

"In particular, screen size and resolution of the display apparatuses have increased, and thus a frame rate conversion function has become increasingly important. Further, an amount of processed information and interfacing between chips has increased. As additional functions are added to the display apparatuses, additional information for a graphic user interface (GUI) is needed to be displayed.

"Thus, as the frame rate conversion is performed on the GUI displayed on a screen together with an image, a boundary of the GUI may be broken or redundantly displayed in response to a size of the GUI being relatively small and a motion amount of the GUI being relatively large. On the other hand, if the frame rate conversion is performed only on the image on the screen, and the GUI is processed separately, an amount of information displayed on the GUI is increased, and a required processing amount is increased."

In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventor's summary information for this patent: "One or more exemplary embodiments may overcome the above disadvantages and other disadvantages not described above. However, it is understood that one or more exemplary embodiment may not overcome the disadvantages described above, and may not overcome any of the problems described above.

"Exemplary embodiments relate to a display apparatus which determines an objects of which a frame rate is to be converted based on a characteristic of the object displayed together with an image and a method thereof.

"According to an aspect of an exemplary embodiment a display apparatus includes: an image processor configured to convert a frame rate of an image signal to a frame rate converted image signal; a display configured to display an image based on the frame rate converted image signal; and a controller configured to control the image processor to add an object to at least one of the image signal and the frame rate converted image signal depending on a characteristic of the object.

"The characteristic of the object may include at least one of a data requirement, a size, and a movement amount.

"The controller may be configured to add the object to the image signal in response to the data requirement being equal to or greater than a preset requirement, and to add the object to the frame rate converted image signal in response to the data requirement being less than the preset requirement.

"The controller may be configured to add the object to the image signal in response to the size being equal to or larger than a preset threshold value and the movement amount being less than a threshold amount, and to add the object to the frame rate converted image signal in response to the size being less than the preset threshold value and the movement amount being equal to or greater than the threshold amount.

"The controller may be configured to determine at least one of the image signal and the frame rate converted image signal to add the object based object position information and the size.

"The controller may be configured to adjust transparency of the object and add the transparency-adjusted object to the frame rate converted image signal based on object transparency information.

"The object may include a first object and a second object and the controller may be configured to determine, based on first object data requirement relative to a preset requirement, whether to add the first object to the image signal or the frame rate converted image signal.

"The controller may be configured to determine, based on second object data requirement relative to the preset requirement, whether to add the first object to the image signal or the frame rate converted image signal.

"The object may include a first object and a second object and the controller may be configured to determine, based on at least one of a first object size relative to a preset threshold value and a first object movement amount relative to a threshold amount, whether to add the first object to the image signal or the frame rate converted image signal.

"The controller may be configured to determine, based on at least one of a second object size relative to the preset threshold value and a second object movement amount relative to the threshold amount, whether to add the second object to the image signal or the frame rate converted image signal.

"According to another aspect of an exemplary embodiment a control method of a display apparatus includes: determining to add an object to at least one of an image signal and a frame rate converted image signal based on an object characteristic; adding the object to at least one of the image signal and the frame rate converted image signal according to a result of the determining; performing frame rate conversion on the image signal; and displaying an image based on the frame rate converted image signal.

"The characteristic of the object may include at least one of a data requirement, a size, and a movement amount.

"The performing of the frame rate conversion on the image may include adding the object to the image signal in response to the data requirement being equal to or greater than a requirement capacity, and adding the object to the frame rate converted image signal in response to the data requirement being less than the requirement capacity.

"The performing of the frame rate conversion on the image may include adding the object to the image signal in response to the size being equal to or larger than a preset threshold value and the movement amount being less than a threshold amount, and adding the object to the frame rate converted image signal in response to the size being less than the preset threshold value and the movement amount of the object being equal to or greater than the threshold amount.

"The displaying of the image of which the frame rate is converted may include determining, based on object position information and object size, which of the image signal and the frame rate converted image signal to add the object to.

"The displaying of the image may include adjusting a transparency of the object based on object transparency information, and adding the transparency-adjusted object to the frame rate converted image signal.

"The object may include a first object and a second object, and the determining may include adding the first object to the image signal or the frame rate converted image signal based on first object data requirement and a preset requirement.

"The determining may include adding the second object to the image signal or the frame rate converted image signal based on second object data requirement and the preset requirement.

"The object may include a first object and a second object, and the determining may include adding the first object to the image signal or the frame rate converted image signal based on a first object size relative to a preset threshold value and a first object movement amount relative to a threshold amount.

"The determining may include adding the second object to the image signal or the frame rate converted image signal based on a second object size relative to the preset threshold value and a second object movement amount relative to the threshold amount.

"According to yet another aspect of an exemplary embodiment an imaging device includes: an image processor configured to perform image signal processing on an input image signal, output a frame rate converted image signal and add an object to at least one of the input image signal and the frame rate converted image signal; and a controller configured to: determine at least one of the input image signal and the frame rate converted image signal to add the object to based on a system resource cost and a threshold system resource cost; and control the image processor to add the object to at least one of the input image signal and the frame rate converted image signal based on the determining.

"The object may include a plurality of objects, and the controller may be configured to determine and control each of the plurality of objects to be added to at least one of the input image signal and the frame rate converted image signal.

"The controller may be configured to determine the system resource cost for the object based on at least one of an object size and an object movement amount.

"Additional aspects of exemplary embodiments will be set forth in the following detailed description, or may be learned by practicing the exemplary embodiments."
