Abstract

The invention discloses a color calibration device and method supporting RGBIR and RGBW formats. The device comprises an RGBIR / RGBW data input unit which is used for acquiring an RGBIR / RGBW image; aninterpolation unit which is used for carrying out interpolation to acquire R, G, B and IR / W those four pieces of full resolution data; an infrared elimination unit which is used for carrying out infrared elimination on four-channel full resolution data acquired through interpolation or carrying out the infrared elimination on data of the RGBIR / RGBW format and then sending the data to the interpolation unit, wherein the data of the RGBIR / RGBW format does not pass the interpolation unit; a white balance unit which is used for adaptively updating white balance of infrared eliminated output data;and a color restoration unit which is used for carrying out color restoration on the image. According to the device and the method, a model for controlling infrared elimination strength is extracted and the white balance and moreover, a color restoration realization mode can be adaptively updated, so the color calibration can be carried out automatically and efficiently.

Description

technical field [0001] The invention relates to the field of image signal processing, in particular to a color correction device and method supporting RGBIR and RGBW formats. Background technique [0002] Currently commonly used based on RGBIR (such as figure 1 (a) or RGBW (such as figure 1 (b)) The correction of the infrared color all uses matrix calculation to perform the correction of the spectrum, but the calibration of the parameters is different. The Chinese patent application of Sony Corporation with the publication number CN102778201A provides an image processing device, image processing Method and program, which can obtain these parameters according to the ideal spectral characteristics and actual spectral characteristics by using the least square method; the Chinese patent application of Shanghai Fullhan Microelectronics Co., Ltd. with the publication number CN103686111A discloses a color based on RGBIR image sensor Calibration method and device, which can obtain...
