Title: Switching structure for catv signal
Inventor: HIGUCHI KEIICHI
IPC: H04N7/16
Filed: 2001-08-06
Abstract: PROBLEM TO BE SOLVED: To facilitate interruption of diversified CATV signals, and facilitate switching of these signals while preventing hit. SOLUTION: A switch SW1 capable of switching the passage or interruption of a signal and a filter 8 are connected to a cable 6 for transmitting a CATV signal, and a switch SW2 is connected to a cable 7. The filter 8 interrupts signal having a specific frequency band. Then, a mixer 10 for mixing the signals of the cables 6 and 7, and for outputting it to a terminal T1 is connected to the filter 8. When only the switch SW1 is turned on, the signal whose specific frequency band is cut is transmitted to the terminal T1. When only a switch SW2 is turned on, the signal whose full frequency band is valid is transmitted to the terminal T1. When the switches SW1 and SW2 are both turned off, the signal is interrupted.

Title: Image processing method and image processor
Inventor: SOGA MINEKI
IPC: H04N9/68
Filed: 2001-08-13
Abstract: PROBLEM TO BE SOLVED: To provide an image processor that implements compression processing at a proper compression rate. SOLUTION: The image processor decides a suppression amount of a low-frequency component from a feature quantity, denoting the spread of a luminance distribution and properly compresses the dynamic range. The input section of the image processor 10 is provided with a high-pass filter 11 and with a luminance variance calculation section 17, and a compression coefficient calculation section 18 placed in parallel with the filter 11. The luminance variance calculation section 17 calculates the variance of the input image, particularly that of the low-frequency components, such as contrast. When the variance is large, that is, when the contrast difference of the low-frequency components is large, the compression coefficient calculation section 18 increases a compression coefficient A. The high-pass filter 11 greatly suppresses the low-frequency component on the basis of it.  Since the low-frequency components are suppressed on the basis of the variance, the suppression is not affected by a local contrast difference, if exists. The image can be compressed at a proper compression rate.
