Document Type and Number:
Japanese Patent JP6551048
Kind Code:
B2
Abstract:
An imaging unit is configured to capture an image of a subject in the water. A lighting unit is configured to illuminate the subject. A histogram generator is configured to divide a range from the minimum to the maximum luminance values of a luminance signal, included in an image signal generated by capturing the image of the subject into a plurality of luminance groups, and to generate histogram data representing the distribution of frequencies of the plurality of luminance groups. Based on the generated histogram data, a histogram analyzer is configured to analyze the distribution of frequencies of the plurality of luminance groups. According to the result of the analysis for the histogram data by the histogram analyzer, a distance controller is configured to control to adjust the distance between the subject and the lighting unit.
