IMAGE PROCESSOR, PROGRAM FOR THE SAME, AND RECORDING MEDIUM FOR THE PROCESSOR

PROBLEM TO BE SOLVED: To provide an image processor, a program for the same, and a recording medium for the processor which are capable of easily obtaining an image in a wide dynamic range and of reducing omissions in minute image information by processing delays or accumulation of arithmetic errors. SOLUTION: The image processor is constituted by a picture signal inputting part 11 for inputting a plurality of picture signals different in exposure time, level conversion coefficient calculation parts 12 and 13 for calculating level conversion coefficients of the plurality of picture signals, a weighting coefficient calculation part 14 for calculating the weighting coefficients of the plurality of picture signals, and an addition part 17 for adding multiplication of the respective level conversion coefficients and the weighting coefficients to the plurality of picture signals.
