Abstract:
1. An image-processing device that reads an image signal from a solid-state image-pickup element where a plurality of unit pixels each including a transistor for detecting a light signal and a photo diode are arranged in a matrix, the device comprising: a first shift register connected to a line of the matrix for reading out an image signal, the first register selecting a line where a signal in response to carriers accumulated in an accumulation state for generating carriers in the photo diode in response to received light is read out; a second shift register connected to a line for clearing an image signal, the second shift register selecting a line for clearing an image signal where residual carriers in the solid-state image-pickup element are discharged from the solid-state image-pickup element; and a first output circuit that outputs shift data applied to the line for reading out an image signal to the first shift register when a number of lines between the line for reading out image signals and the line for clearing image signals is equal to or less than a total number of lines in the matrix and a condition for picking an image up is changed, wherein the condition is at least one selected from the group consisting of a change in a frame rate, a change in a shutter speed, and a change in a scanning direction.
