IMAGING DEVICE, IMAGING SYSTEM, AND IMAGING METHOD

摘要

An imaging device includes a histogram unit that extracts luminance information from video signals obtained by image capture and generates a histogram, a white balance detector unit that detects the deviation in the white balance of the video signal, and a white balance processor unit that corrects the white balance of the video signal; and along with selecting the imaging conditions of the imaging unit based on the deviations detected by the white balance detector unit, also controls the white balance processor unit. When there is a large deviation in the white balance, the imaging device decides whether or not to correct the white balance according for example to the hue.

主权项

1. An imaging device that outputs signals relating to an image-captured imaging object, comprising:
an imaging unit that generates electrical signals relating to the imaging object whose image is captured; a signal processing unit that processes electrical signals generated in the imaging unit, and generates video signals including luminance information and color information; a histogram unit that generates histograms based on luminance information contained in the video signal generated by the signal processing unit; a white balance detector unit that detects deviations in the white balance of the video signal based on color information contained in the video signal generated by the signal processing unit; a white balance processor unit supplied with a video signal generated by the signal processing unit, and that corrects the white balance of the video signal based on the deviation in white balance detected by the white balance detector unit; an image output unit that outputs the video signal whose white balance is corrected by the white balance processor unit; and a control unit that controls the operation of the structural elements of the imaging device, wherein the control unit controls the imaging unit and the white balance processor unit based on the histogram generated by the histogram unit and the deviation in the white balance detected by the white balance detector unit.
