Abstract
PURPOSE: To enable signal processing of the photoelectric transmutation element group output without space frequency dependency by a method wherein the video signal difference is by turns obtained at time intervals different according to the space frequency differences of a subject and said signal differences are non-linearly processed.
CONSTITUTION: The photoelectric transmutation element group 1 which is given luminous flux from a subject is driven by a pulse driver 2 to put out by turns video signals. The video signals are separated respectively into a relatively high frequency component, intermediate component, relatively low component of space frequency. The time intervals τ1Wτ3 in the sampling lines f1Wf3 for each separation signal are selected long for the low component and short for the high component in the delay circuits 15-1 and the like. In the substruction circuits 11-1 and the like the output differences of the sampling circuits of the 9-1 class, 10-1 class are operated and the video signal differences are by turns obtained at τ1Wτ3 intervals. Said outputs are linearly processed in the square circuits 12-1 class, addition circuits 13-1 class.
