Patent ID: 6989823

Claim:
An apparatus comprising: a frame conversion unit to convert frames of analog image data to frames of digital image data; a buffer coupled with the frame conversion to store the frame of digital image data and subsequent converted frames; a pixel value comparator coupled with the buffer to compare pixel data of the frame of digital image data and pixel data from the subsequent converted frame using horizontal position counter to compare and identify a subsequent converted frame having pixel data that differs from the pixel data of the frame of digital image data by a threshold amount; a capture switch configured to be set to on when the subsequent converted frame pixel data exceeds the threshold amount and where the capture switch is configured to be set to off when the subsequent converted frame pixel data is below the threshold amount; a microcontroller configured to capture the subsequent converted frame with pixel data that exceeds the threshold amount for storage to replace the frame of digital image data and display by a display object, and discard frames with pixel data that below the threshold amount.
