Abstract
An image processing apparatus that can determine an optimal registration color according to an acquired image is provided. An image processing unitreceives a sample image from an imaging unitand acquires a hue with respect to each of pixels arranged two-dimensionally that constitute the sample image and calculates a hue histogram. A control unitextracts a candidate color based on the hue at a maximum point in the hue histogram received from the image processing unit. At the same time, the control unitdetermines a hue threshold value in order to define the range of the color regarded as the candidate color. Furthermore, the control unitextracts all pixels that satisfy the hue threshold value of the candidate color and acquires the value and chroma of the extracted pixel and sets the maximum value and the minimum value in the acquired value and chroma to a value threshold value and a chroma threshold value. The control unitstores the determined hue threshold value, value threshold value and chroma threshold value in a memory unit
