Disclosed herein is an imaging device having a lens including a zoom lens and a focus lens; an image sensor for outputting an imaging result of an optical image formed by the lens; a signal processor for processing the imaging result to output a video signal; a detector for processing the video signal to output an evaluation value indicative of the degree of focusing; a memory for storing data of an imaging range where a focused image is ensured, by using a cam curve of the lens; and a controller for moving the focus lens in concert with the zoom lens; wherein when a focal depth detected according to a current position of the zoom lens is less than the imaging range at the current position of the zoom lens, the controller performs autofocus control using the evaluation value to move the focus lens; and when the focal depth is greater than the imaging range at the current position of the zoom lens, the controller performs focus control by the cam curve to move the focus lens. Thus, the autofocus control and the focus control by the cam curve are switched to each other according to the result of comparison between the focal depth and the imaging range at the current position of the zoom lens.

摘要:
A dot pattern with a plurality of pixels representing a two-dimensional image is formed on a printing plate material by applying laser beams, which are turned on and off for each pixel depending on dot pattern data, to the printing plate material in a main scanning direction, while the laser beams are moved in an auxiliary scanning direction that is orthogonal to the main scanning direction. A threshold matrix having an array of thresholds is obtained for generating a dot where the degree of a variation of the dot periphery length in a main scanning direction is smaller, i.e., a dot where the dot periphery length in the main scanning direction has a smaller standard deviation.
