1. An imager component comprising: an image sensor having a pixel array organized into rows and columns, the array configured to capture an image, the sensor further comprising an output bus configured to output digital data corresponding to the captured image; and a frame memory connected to the image sensor via at least one bus, said image sensor comprising a memory controller configured to control data transfers between the frame memory and the image sensor; wherein the image sensor further comprises: column parallel analog readout circuitry connected to the columns, the column parallel analog readout circuitry converting signals associated with the captured image into the digital data; and a plurality of pixel line buffer memories, each line buffer memory being connected to and associated with a group of columns and storing a respective portion of the digital data associated with the respective group of columns, the line buffer memories configured to store the digital data from the column parallel analog readout circuitry during the readout operation, wherein the controller causes all of the digital data to be sequentially stored in the frame memory.
