PURPOSE:To extract and transmit only the image of the figure of a person having the body temperature in case of applying, for instance, to a video telephone set, and to shorten the transmission time by transmitting the image information of an object whose temperature is above a prescribed value selectively. CONSTITUTION:A thermal detector 1 and a video camera 2 are so constituted as to pick up an image at the same image pickup range provided in the vicinity. An analog signal from the camera 2 is converted to a digital signal by a video signal A/D converter 3, and the digital signals are stored sequentially in a semiconductor memory 5. Also, image information representing the thermal distribution obtained by the detector 1 is converted to digital information by a conversion device 4, and stored in a semiconductor memory 8. A microcomputer 6 can know the temperature of the respective parts of the image information stored in the memory 5 from the memory 8, and issues an instruction to a memory transfer equipment 7 to transfer only the image information (for instance, the person's figure in the oblique line zone) in a part where the temperature is above the prescribed value from the memory 5 to a transmission equipment 9. |
