摘要： An image sensor architecture that accommodates the relative mismatch of bus width between the image sensor, processor, and memory is disclosed. The preferred embodiment of the invention provides a dual-ported memory structure having a relatively wide data port for receiving data from the image sensor and having a relatively narrow data port for communicating data to and from the processor. In one embodiment of the invention, the memory is organized into banks of a specific width. The banks may be accessed sequentially by the processor, such that the bus width is equivalent to the bank width, and the banks may be accessed simultaneously, such that the bus width is equivalent to the combined bank widths. A simple switching means, operating under processor control, reconfigures the memory on the fly.

There is provided a support substrate on which the nonplanar charge storage substrate is supported to maintain the selected surface profile of the charge storage substrate. An array of pixels defined in the charge storage substrate by pixel interconnections is supported on the front side of the substrate, such that exposure of the substrate to light from the scene through the lens produces charge packets in the pixels, with the pixel interconnections providing selective electronic temporal control of transfer of charge packets from one pixel to another in the substrate. Also provided is means for suppressing generation of dark current charge packet generation in the substrate pixels. Anan output circuit converts the charge packets in the pixels to an electrical pixel signal of output pixel values based on the light from the scene. A plurality of pixel values together form an image frame, the output pixel values being produced at a rate corresponding to the image frame rate, R.

摘要： Embodiments of the present invention provide systems and methods for converting an achromatic, higher-resolution image to a lower-resolution image with reduced visible errors. These systems and methods comprise a sub-pixel sampling performed on a higher-resolution image. The sub-pixel sampled image is then converted to an opponent color domain image that is separated into separate luminance and chrominance channels. These chrominance channels are then high-pass filtered and combined with the luminance channel to form a filtered opponent color domain image.
