Video signal processor and method of processing video signal

摘要

In a video signal processor, a difference value calculation section calculates a difference value between video signals at two or more different points of view, which have been input to a video signal input section, at each predetermined timing. A compensation value calculation section holds the difference value between the video signals, which have been obtained at the predetermined timing, at each predetermined time interval. The compensation value calculation section calculates a compensation value with reduced compensation variations along a time axis using the held difference value. A video signal compensation section compensates the video signals using the obtained compensation value. Furthermore, the compensation value calculation section also calculates the compensation value with reduced compensation variations along the time axis based on information at imaging, which has been obtained by an information input section at each predetermined timing.

1. A video signal processor comprising:
a video signal input section configured to receive video signals at two or more different points of view; a difference value calculation section configured to calculate a difference value between the video signals at the two or more points of view, which have been obtained at each predetermined timing; a compensation value calculation section configured to hold a plurality of difference values, which have been obtained by the difference value calculation section, at predetermined time intervals, and calculate a compensation value using the difference values to reduce compensation variations along a time axis among the plurality of difference values; a video signal compensation section configured to compensate a difference between the video signals using the compensation value, which has been obtained by the compensation value calculation section, and to output the video signals whose difference has been compensated; a control signal generation section configured to generate a control signal using the compensation value which has been obtained by the compensation value calculation section and to output the control signal; and an information input section configured to receive information at imaging, wherein the compensation value calculation section holds the difference value, which has been obtained by the difference value calculation section, and the information at the imaging, which has been obtained by the information input section at each predetermined timing, at each predetermined time interval, and calculates the compensation value with reduced compensation variations along the time axis based on the information at the imaging using the held difference value.
