Abstract
An exposure controller for an on-vehicle camera mounted on a vehicle is capable of performing exposure control such that a predetermined subject such as a lane marker can be imaged with a constant contrast regardless of variation of peripheral brightness and directions of the variation. An exposure controller images information imaged by an imaging part based on a second exposure property having linearity, the second exposure property being obtained by converting a first exposure property having non-linearity, calculates a target density value with which pixels in a window set in the image are to be imaged based on brightness values corresponding to density values of the pixels in the window, sets a third exposure property for obtaining the calculated target density value, and performs imaging with the set third exposure property.
