Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0027] figure 1 It is a diagram showing the overall configuration of a color adjustment device according to an embodiment of the present invention. figure 1 The illustrated color adjustment device 20 has a housing including two chambers, a light source chamber 20 a and a camera chamber 20 b. These light source chamber 20 a and camera chamber 20 b are separated by a circular hole plate 23 . A circular hole 23 a is formed in the circular hole plate 23 .

[0028] A dark box 21 is arranged in the light source chamber 20a. A circular hole 21a is formed on the surface of the camera obscura 21 facing the camera chamber 20b. In addition, a light source 22 is provided in the dark box 21 . The light source 22 is, for example, a standard light source such as the A light source. exist figure 2 The spectral sensitivity characteristic of this light source A is shown in . Her...

Abstract

The invention provides a color adjusting device with high accuracy, which can prevent the bigness of devices and increasing of time adjustment without depending on the characteristics of infrared end filter glass. Based on the color signal data obtained by rotating a BPF disc (24) while shooting with a digital camera (26), the relative spectral sensitivity data of a shooting system component with certain wavelength can be obtained. By using the color signal data obtained through shooting and reference data, the relative spectral sensitivity data of interpolation wavelength other than specific wavelength can be calculated. Based on a predetermined interpolation equation using the relative spectral sensitivity data with wavelengths of 620nm and 640nm obtained based on the color signal data, the relative spectral sensitivity data of a wavelength of 630nm can be calculated. After the relative spectral sensitivity data of the specific wavelength and the interpolation wavelength is obtained, the spectral sensitivity data of each color component of the shooting system elements can be obtained through sample interpolation.

Description

technical field [0001] In particular, the invention relates to a color adjustment device suitable for digital cameras. Background technique [0002] The imaging system components of a general digital camera include an imaging lens group, an infrared cut filter, and an imaging element. In such an imaging system component, light incident through an imaging lens group is imaged on an imaging element to become an image signal. [0003] Here, a color filter is arranged in front of the imaging element. A color filter has a large variation in spectral sensitivity characteristics, which greatly affects the color reproduction of an image of a digital camera. In order to minimize this influence in the digital camera, it is necessary to adjust the correction value in the color adjustment processing for each digital camera. [0004] As an example of such a color adjustment device, in Patent Document 1, imaging is performed with a band-pass filter interposed between a predetermined li...
