Patent ID: 8471931

Claim:
A video recording system, comprising: an image pickup element, which is configured to convert a light into an electric signal; an optic system, which is configured to form an image by condensing the light on said image pickup element; and a signal process unit, which is configured to input the electric signal outputted from said image pickup element, so as to treat a signal process, and thereby to output one or plural numbers of processing result(s), wherein for each of the output(s) of said signal processing unit, The video recording system further having: a converter unit, which is configured to treat an orthogonal transformation on an output of said signal processing unit, and thereby produces a frequency conversion signal; a delaying unit, which is configured to delay said frequency conversion signal, and thereby to output a frame or field delay signal; a correlation produce unit, which is configured to obtain a correlation between said frequency conversion signal and said frame or field delay signal; a second delaying unit, which is configured to delay an output of said signal process unit, and thereby to output a second frame or field delay signal; a filtering unit, which is configured to conduct a filter process on an output of said signal process unit, with using the second frame or field delay signal; a controller unit, which is configured to control processing contents of said filter process with using an output of said correlation produce unit, wherein the filter process is executed on the output of said signal process unit, depending on the correlation between said frequency conversion signal and said frame delay signal.
