    Abstract: An image capture apparatus that includes an array of color filters for green, red, and magenta colors arranged over a semiconductor substrate in the manner of a primary color Bayer pattern except a magenta color replaces the blue color. Light passing through the magenta color filter is integrated separately in a magenta pixel for a shallow photodiode signal and a deep photodiode signal in a first photodiode and a deeper second photodiode in the substrate, respectively. A mezzanine photodiode may be disposed between the first and second photodiodes and held at a fixed voltage level or reset multiple times during charge integration. A red pixel value for the magenta pixel is a function of the deep photodiode signal and an adjacent red pixel's red pixel signal. A minimum exists in its derivative with respect to the former at a value of the former that varies with the latter.

    Abstract: A spectral camera for producing a spectral output is disclosed. The spectral camera has an objective lens for producing an image, an optical duplicator, an array of filters, and a sensor array arranged to detect the filtered image copies simultaneously on different parts of the sensor array. Further, a field stop defines an outline of the image copies projected on the sensor array. The filters are integrated on the sensor array, which has a planar structure without perpendicular physical barriers for preventing cross talk between each of the adjacent optical channels. The field stop enables adjacent image copies to fit together without gaps for such barriers. The integrated filters mean there is no parasitic cavity causing crosstalk between the adjacent image copies. This means there is no longer a need for barriers between adjacent projected image copies, and thus sensor area can be better utilized.

A first pixel is covered by the first color filter component. A first color pixel signal is generated by the first pixel. The first output line outputs only the first color pixel signal. A second pixel is covered by the second filter component. A second color pixel signal is generated by the second pixel. The second output line outputs only the second color pixel signal.

  • Patent number: 7583303
    Abstract: An imaging device having a hybrid RGBYC color filter using a primary color system RGB filter and a complementary color system YC filter is composed. Four G filters that directly relate to resolution and that is close to a luminance signal that human eyes sense are arrayed in a checker shape so that the number of the G filters is four times larger than the number of filters of each of the other colors. An array shown in FIG. 10A is composed of low resolution rows (G, R, G, and B) and high resolution rows (C, G, Y, and G) that are alternately arrayed in each line. When signals are read if exposure times are varied for individual lines, the signals that are read can easily have a wide dynamic range. An array shown in FIG. 10B has two Gs, a low sensitivity color, and a high sensitivity color in each line and each row. Thus, the luminance difference is small in the horizontal direction and the vertical direction. Thus, the reading method in the array shown in FIG.

  • Patent number: 7154545
    Abstract: Photosensor assemblies have, for each color, multiple line-arrays of photosensors. For each color, the spectral bandwidth received by each line-array is different. The additional spectral bandwidths are used to improve the spectral measurement accuracy, and to increase bit-depth. In one example, one row of a staggered array receives light having a first spectral bandwidth, and a second row of the staggered array receives light having a different spectral response. In a second example, photosensors with different sizes receive light having different spectral bandwidths.

  • Patent number: 5424543
    Abstract: A spectroradiometer images a scene as a repeating sequence of spectral images, each of which spectral images depicts the scene at a preselected wavelength. In a preferred embodiment, the image is of size 256 by 192 pixels, and the sequence repetition rate is about 20-30 cycles per second. Full spectral analysis on the resulting sequences is performed substantially in real time. The spectroradiometer includes a light collector with a lens, a circularly variable spectral filter, and an optical gate which gates the output of the filter to a detector array which outputs the sequence of electronic spectral images. These images are corrected for systematic errors and calibrated, and correlated with a preselected spectral response function. The image may be further post-processed and displayed in video format or used otherwise.
