In imaging processing, image data outputted from an imaging device is acquired as a data string formed of a first display value expressed by a first number of gradations obtained through conversion of a luminance value in accordance with preset nonlinear conversion characteristics. The first display value is compressed in accordance with preset compression characteristics, and outputted as a second display value expressed by a second number of gradations smaller than the first number of gradations. A recognition target is detected from an image expressed by compressed data that is a data string formed of the second display value. A ratio of the second number of gradations to the first number of gradations is taken as a basic compression ratio, a luminance range including at least a recognition target range that is a luminance range where the recognition target is estimated to be present is taken as a specified range, and the first display value corresponding to a boundary luminance value that is a minimum luminance value in the specified range is taken as a boundary first display value. In the recognition target range, the compression characteristics are set so that the second display value is a sum of a compressed value and the boundary first display value, the compressed value being obtained by compressing a value of not less than the boundary first display value among the first display values at a low compression ratio lower than the basic compression ratio.
