Object detection post-processing device, and display device including the same

An object detection post-processing device of a display device, the object detection post-processing device comprising:

• an input configured to receive position information of an object that is detected from input image data for the display device in a current frame;
• a position information storage device configured to accumulatively store the position information of a plurality of previous frames;
• a state determiner configured to generate state information representing one of a non-output state, a prompt output state, an accumulated output state, a previous accumulated output state, and a channel change state as an operating state of the object detection post-processing device;
• an accumulated position calculator configured to generate accumulated position information according to the position information of the current frame and the position information of the plurality of previous frames when the state information represents the accumulated output state, and to generate the accumulated position information according to the position information of the plurality of previous frames when the state information represents the previous accumulated output state;
• and
• a position information determiner configured to determine final position information according to the state information and the accumulated position information, and to output the final position information.

A display device comprising:

• a display panel comprising a plurality of pixels;
• a data driver configured to provide data signals corresponding to output image data to the plurality of pixels;
• a scan driver configured to provide scan signals to the plurality of pixels;
• and
• a controller configured to control the data driver and the scan driver, the controller comprising:
• an object detection device configured to detect an object from input image data to generate position information of the detected object;
• an object detection post-processing device configured to determine final position information according to the position information of the detected object;
• and
• a data compensation device configured to generate the output image data by compensating the input image data according to the final position information,
• wherein the object detection post-processing device comprises:
• an input configured to receive the position information of a current frame from among a plurality of sequential frames;
• a position information storage device configured to accumulatively store the position information of a plurality of previous frames from among the plurality of sequential frames;
• an accumulated position calculator configured to generate accumulated position information according to the position information of the current frame and the position information of the plurality of previous frames;
• a state determiner configured to generate state information representing one of a non-output state, a prompt output state, an accumulated output state, a previous accumulated output state, and a channel change state as an operating state of the object detection post-processing device;
• and
• a position information determiner configured to determine the final position information according to the accumulated position information, and to output the final position information,
• wherein the final position information is determined based on the state information and the accumulated position information.
