摘要： A first set of different color signals represented in a colorimetric system is converted into a second set of different color signals represented in another colorimetric system. Predetermined main parts of the second set of the color signals are determined in response to predetermined first portions of the first set of the color signals. Calculation coefficients are determined in response to the first portions of the first set of the color signals. Predetermined subordinate parts of the second set of the color signals are calculated from predetermined second portions of the first set of the color signals and the calculation coefficients according to an interpolation. The determined main parts of the second set of the color signals and the calculated subordinate parts of the second set of the color signals are combined into a whole of the second set of the color signals. The calculation coefficients are designed so that, if the color signals in the first set vary by equal values, achromatic color data which results from the calculation lies on an achromatic color axis in a color space defined with respect to the readout data of the main parts of the second set of the color signals, and that the sum of squared errors of color conversion is minimized.

摘要： A color separation stripe filter in a color image pickup apparatus in which a color image is focused on a photo-electric conversion target through the filter to be converted to an electrostatic image so as to generate a color multiplexed signal. The filter comprises a plurality of recurrent groups of three different color stripes successively arranged at periodic intervals. The first color stripe has a characteristic showing a peak transmission factor in a red color region, the second color stripe has a characteristic showing a peak transmission factor in a green color region which is substantially equal to the peak transmission factor of the first color stripe, and the third color stripe has a characteristic showing a negative peak transmission factor at a wavelength between 500 nm and 530 nm so as to produce first and second peak transmission factors in a blue region and said green region. The first peak transmission factor is substantially equal to each of the peak transmission factors of the first and second color stripes and the second peak transmission factor existing in the green color region to be 50% to 80% of each of the peak transmission factors of the first and second color stripes, a curve of the characteristic of the third color stripe in the green region being substantially similar in configuration to that of the second color stripe.

摘要： A solid-state imaging apparatus includes an image pick-up section in which photosensitive devices are arranged in, e.g., a honeycomb G square lattice, RB full-checker pattern due to shifted pixels. Regions void of the photosensitive devices are assumed to be virtual photosensitive devices. A signal processing section generates data for the virtual photosensitive devices by using the data of surrounding photosensitive devices while attaching importance to accurate color reproduction and horizontal and/or vertical resolution. As a result, the number of pixel data are increased in a square lattice arrangement. Therefore, high quality image signals are readily achievable with a smaller number of photosensitive devices than conventional with a conventional apparatus. Interpolation can be executed with the high quality signals to the limit of resolution with an adequate circuit scale. The honeycomb arrangement guarantees the required size of the individual pixel and thereby the sensitivity of the entire apparatus while increasing yield on a production line. False colors particular to a single photosensitive portion can be reduced by, e.g., uniform interpolation. Particularly, when a digital camera is constructed by using an imaging apparatus including optics operable with a silver halide sensitive type of film, false colors can be reduced without resorting to an optical low pass filter.

摘要： A solid-state image sensor capable of enhancing efficient use of incident light and increasing the resolution of an image and a signal processing method therefore are disclosed. A digital camera includes an image pickup section having a photosensitive array in which photosensitive cells or photodiodes are arranged. Signal charges, or pixel data, are read out of the photodiodes, two lines at a time, three lines at a time, or three lines at a time with line-by-line shift in accordance with a color filter using complementary colors. A signal processing section includes a data correcting circuit for correcting the pixel data. Pixel data of one of three primary colors R, G and B is interpolated in the position of each virtual photosensitive cell or that of each real photosensitive cell. The above color filer uses more efficiently incident light than a filter using the primary colors and improves the sensitivity of the photosensitive cells in a dense pixel arrangement, thereby contributing to the enhancement of image quality. Further, the generated pixel data are used to interpolate pixel data in the real photosensitive cells or the virtual photosensitive cells. This is successful to broaden the frequency band of the pixel data of the real photosensitive cells or those of the virtual photosensitive cells and therefore to improve image quality while obviating false colors.

摘要： In a digital camera, an image pickup section feeds pixel data to a signal processor that uses green pixel data as high-frequency luminance data. To generate luminance for a subject pixel that is either a red pixel or a blue pixel, the signal processor determines a direction of correlation by using the subject pixel and pixel data identical in color with the subject pixel and adjoining it in horizontal and vertical directions. The signal processor then generates, based on the subject pixel and the pixel data used for the above decision, a color complementary to green as high-frequency luminance data while attaching a flag indicative of the direction of correlation to the pixel data. Further, by comparing flag patterns, the signal processor corrects the above flag and then generates high-frequency luminance data from pixel data positioned in a direction indicated by the flag. This obviates a difference in level between nearby pixels in a direction of length.

摘要： An image pickup device comprises an image pickup tube and an index generator having a light shield box; a light emitting diode held in the light shield box; a stripe screen provided on the photosensitive layer of the image pickup tube and shading compensation filter having transmittance pattern which equalizes illuminance variation on the stripe pattern of the stripe screen caused by the light emitting diode so that illuminance at any point of the stripe pattern becomes uniform. The image pickup tube generates picture signal together with index signal which is derived from the projected stripe pattern image on peripheral portion of the photosensitive layer through the shading compensation filter which equalizes index signal output level to make timing derived from the index signal accurate. A method of providing shading compensation filter is disclosed where a sheet of negative film is placed on the opening of the light shield box, exposed to the light emitting diode. Then the sheet of film is developed by chemical process.

摘要： A solid-state image pickup apparatus includes a color filter including complementary color filter segments. When a shutter release bottom is pressed to its half-stroke or full-stroke position, light incident via the filter is picked up in a movie/photometry or a still picture mode, respectively. While signal charges are read out of an image sensor in accordance with the mode, the signal charges are digitized to become pixel data. In the movie/the photometry mode, despite that a plurality of pixel data are mixed together, a set of primary color pixel data are generated as if pixel signals were thinned out by mixture. In the still picture mode, all the pixels are sequentially read out and interpolated to generate primary color pixel data greater in number than photosensitive cells. The primary color data are raised in frequency to enhance the resolution of a picture.
