摘要： Levels of an input video signal are detected at successive pixels. An absolute level difference is produced that is an absolute value of the difference at each pixel pair. One absolute difference is applied nonlinear processing to be subtracted from an initial value to obtain a subtracted value. An absolute value of the subtracted value is set to a predetermined value if not larger than this value. The absolute difference is obtained from a pixel pair located in the middle of the pixels. The absolute value subjected to the nonlinear processing is added to the remaining absolute differences, to obtain an evaluation value. The input signal is subjected to low-pass filtering, thus video signals being output with high-frequency components attenuated depending on filter characteristics. The input signal with no filtering applied or one of the signals applied the filtering is selected for edge enhancement depending on the evaluation value.

摘要： An input video signal is processed for edge enhancement. Video signal levels are detected at an N number of pixels located adjacent to one another in a specific scanning direction (N being an even number of four or larger). A difference between the levels is obtained and an absolute difference is produced that is an absolute value of the difference at each pair of adjacent two pixels among the N number of pixels, thus an (N−1) number of absolute differences being obtained. A particular one absolute difference among the absolute differences is applied nonlinear arithmetic processing in which it is subtracted from a predetermined initial value to obtain a subtracted value, and an absolute value of the subtracted value is obtained, the absolute value being set to a predetermined value if equal to or lower than the predetermined value. The particular one absolute difference is obtained from a pixel pair of two adjacent pixels located in the middle of the N number of pixels aligned in the scanning direction. The absolute value of the subtracted value subjected to the nonlinear processing is added to the remaining (N−2) number of absolute differences not subjected to the nonlinear processing, thus an evaluation function value being obtained. The input video signal is subjected to low-pass filtering with different filter characteristics, thus video signals being output with high-frequency components attenuated depending on the different filter characteristics. The input video signal with no filtering applied is selected for edge enhancement if the evaluation function value is larger than a reference value whereas one of the video signals applied the filtering is selected for edge enhancement if the evaluation function value is equal to or smaller than the reference value, the smaller the evaluation function value, selected being one of the video signals having the high-frequency components attenuated more.

摘要： An electronic device that performs several types of operations under control by a remote controller equipped with a plurality of function keypads, has a power supply to supply power to the electronic device, a power controller to control the power supply to turn on or off the electronic device, a display unit to display several types of information, and a display controller to control the display unit to display visual information, in response to an operation of a keypad among the function keypads of the remote controller in a keypad function guidance mode in which visual information including guidance on a function of an operated keypad is allowed to be displayed on the display unit. The display controller controls the display unit to display first visual information including guidance on a function of a power keypad among the function keypads of the remote controller when the power keypad is operated in the keypad function guidance mode while no prior visual information including guidance on a function of an operated keypad is being displayed or while second visual information including guidance on a function of an operated keypad other than the power keypad is being displayed. The power controller controls the power supply to turn off the electronic device when the power keypad is operated in the keypad function guidance mode while the first visual information is being displayed.
