Claims

[Claims for Utility Model Registration] 1. In a photoelectric conversion device that obtains an image signal by imaging a light source that illuminates a subject and the reflected light from the subject that receives the light source on a photoelectric conversion element through an optical filter, a color detection means for detecting a desired specific color among a plurality of colors provided by the color detection means; a control signal generation means for generating a control signal for extracting the desired color from the color information detected by the color detection means;
A photoelectric conversion device comprising a color extracting means for receiving the control signal and extracting the desired color, and extracting the desired color from the subject. 2. The color detecting means includes a first voltage generating means that generates at least one voltage, and a first voltage generating means that generates at least one voltage; 2. The photoelectric conversion device according to claim 1, further comprising a first optical filter that passes color information. 3. In the color extracting means, a second voltage generating means generates a voltage corresponding to the voltage applied to the first filter when the color detecting means detects a desired color in response to the control signal; 2. The photoelectric conversion device according to claim 1, further comprising a second optical filter whose spectral transmission characteristics change in accordance with the voltage of the octopus, and which passes color information corresponding to the voltage.
