Abstract

A method for calculating the vertical smear charge of a solid photographing element, characterized in arranging a plurality of photorecepting bits in the column direction and the row direction of the solid photographing element, while the information charge accumulated on each photorecepting bit in a specified period is being periodically transmitted in the row direction and transmitted and outputted one by one in the column direction, based on the ratio between the accumulation time of the information charge of the amount of information charge accumulated in each photorecepting bit and the transmission period in the column direction of the information, for each photorecepting bit, estimating the amount of smear charge introduced during the process of transmitting the information charge stored in each photorecepting bit in the column direction, and accumulating the estimated values into the portion of the photorecepting bits in the transmission path of the information charge to obtain the smear charge.
