An integrated image sensor for acquiring and processing electrical signals representative of an object comprising a photosite array configured to convert light into the electrical signals, an A/D converter configured to convert the electrical signals into digital data, and logic integral with the image sensor configured to scale the digital data by a non-integer-scaling factor. A method for acquiring and processing image data with an integrated image sensor comprising the steps of capturing, via the image sensor, the image data representative of an image, scaling, via the image sensor, the image data by a non-integer value, and outputting from the integrated image sensor scaled image data.
A solid-state imaging element includes photoelectric conversion elements having a complementary or Bayer color filter array. The solid-state imaging element adds together electric charges stored in nine photoelectric conversion elements having color filters of one of multiple colors in each portion of six rows and six columns, to obtain a resulting electric charge, and outputs the resulting electric charge as one pixel. A portion for one of the colors deviates from a portion for each of the other colors by three rows and/or three columns. This pixel-addition operation produces an effect of a spatial low pass filter, thereby reducing signal components exceeding a Nyquist frequency corresponding to a target resolution. Consequently, aliasing noise in an image with the target resolution is reduced, and therefore higher image quality can be achieved, when compared with a conventional resolution reduction technique.
An object to be imaged or detected is illuminated by a single broadband light source or multiple light sources emitting light at different wavelengths. The light is detected by a detector, which includes a light-detecting sensor covered by a hybrid filter.
An image processing system that receives source image data with a first resolution and renders a target image data onto a display having a second subpixel resolution and improves image quality in said rendered target image data is described.
