IMAGE SENSING APPARATUS AND METHOD OF CONTROLLING OPERATION OF SAME

摘要

A subject is imaged repeatedly and color images of the subject are obtained. A color histogram is generated from the color subject image obtained and a representative color is decided from the color histogram generated. A specific color range that can be considered a color identical with the representative color is decided from the color histogram and representative color. Color outside the specific color range in the color subject image is changed to gray, an image of the subject in which the non-specific colors have been changed to gray is obtained and the image is displayed. Processing such as deciding the specific color range is repeated. When an instruction to fix the specific color is issued, the specific color range is fixed.

主权项

1. An image sensing apparatus comprising:
a color imaging device for sensing the image of a subject and outputting color image data representing a color image of the subject; a specific color decision device for analyzing the color image of the subject. and deciding a specific color from the color image of the subject; a specific color range decision. device for deciding a specific color range indicating the range of a color that can be considered. a color substantially identical with the specific color decided by said specific color decision device; a saturation adjustment device for changing color saturation of the color image of the subject, said saturation adjustment device changing saturation of color within the specific color range decided by said specific color range decision device or of color outside the specific color range decided by said specific color range decision device; a display control device for controlling a display unit so as to display the color image of the subject the color saturation of which has been changed by said saturation adjustment device; an imaging control device for exercising control so as to repeat processing for outputting a color image of the subject, processing for deciding a specific color, processing for deciding a specific color range, processing for adjusting saturation and processing for controlling display of the color image of the subject, these processes being executed by said color imaging device, said specific color decision device, said specific, color range decision device, said saturation adjustment device and said display control device; and a saturation adjustment control device, operative upon receipt of a specific color fixing instruction, for controlling said saturation adjustment device so as to adjust saturation of the color image of the subject based upon a specific color range fixed by said specific color fixing instruction.
