Abstract
An image processor 7 includes: an in-focus area extracting section 72 that extracts an in-focus area of two images with parallax; a color conversion matrix calculating section 73 that obtains a color conversion matrix between the two images by reference to information about the colors of pixels that are included in the in-focus area of the two images; and a color conversion section 74 that converts the color of one of the two images by using the color conversion matrix.
Claims9
An image processor that matches the colors of two images with parallax to each other, the two images having been captured by a device comprising a light transmitting section that has two transmitting areas with mutually different spectral transmittance characteristics;
- and an image sensor that is arranged to receive the light that has been transmitted through the light transmitting section and that includes two kinds of pixels with mutually different spectral transmittance characteristics, both of the two kinds of pixels configured to detect at least a part of light rays that have been transmitted through one of the two transmitting areas and at least a part of light rays that have been transmitted through the other of the two transmitting areas, the processor comprising:
- an in-focus area extracting section that extracts an in-focus area of the two images;
- a color conversion matrix calculating section that obtains a color conversion matrix between the two images by reference to information about the colors of pixels that are only included in the in-focus area of the two images;
- and
- a color conversion section that converts the color of one of the two images by using the color conversion matrix.
A 3D image capture device comprising:
- a light transmitting section that has two transmitting areas with mutually different spectral transmittance characteristics;
- an image sensor that is arranged to receive the light that has been transmitted through the light transmitting section and that includes two kinds of pixels with mutually different spectral transmittance characteristics, wherein both of the two kinds of pixels are configured to detect at least a part of light rays that have been transmitted through one of the two transmitting areas and at least a part of light rays that have been transmitted through the other of the two transmitting areas;
- and
- an image processing section that generates two images with parallax based on pixel signals supplied from the image sensor, and
- wherein the image processing section includes:
- an in-focus area extracting section that extracts an in-focus area of the two images;
- a color conversion matrix calculating section that obtains a color conversion matrix between the two images by reference to information about the colors of pixels that are only included in the in-focus area of the two images;
- and
- a color conversion section that converts the color of one of the two images by using the color conversion matrix.
An image processing method for matching the colors of two images with parallax to each other, the two images having been captured by a device comprising a light transmitting section that has two transmitting areas with mutually different spectral transmittance characteristics;
- and an image sensor that is arranged to receive the light that has been transmitted through the light transmitting section and that includes two kinds of pixels with mutually different spectral transmittance characteristics, both of the two kinds of pixels configured to detect at least a part of light rays that have been transmitted through one of the two transmitting areas and at least a part of light rays that have been transmitted through the other of the two transmitting areas, the method comprising the steps of:
- extracting an in-focus area of the two images;
- obtaining a color conversion matrix between the two images by reference to information about the colors of pixels that are only included in the in-focus area of the two images;
- and
- converting the color of one of the two images by using the color conversion matrix.
An image processing program stored on a non-transitory computer readable medium for matching the colors of two images with parallax to each other, the two images having been captured by a device comprising a light transmitting section that has two transmitting areas with mutually different spectral transmittance characteristics;
- and an image sensor that is arranged to receive the light that has been transmitted through the light transmitting section and that includes two kinds of pixels with mutually different spectral transmittance characteristics, both of the two kinds of pixels configured to detect at least a part of light rays that have been transmitted through one of the two transmitting areas and at least a part of light rays that have been transmitted through the other of the two transmitting areas, the program, when executed by a processor of a computer, causes the computer to perform the steps of:
- extracting an in-focus area of the two images;
- obtaining a color conversion matrix between the two images by reference to information about the colors of pixels that are only included in the in-focus area of the two images;
- and
- converting the color of one of the two images by using the color conversion matrix.
