Abstract:
1. An image processor for controlling transfer of pixel signals between an image sensor and a memory storing said pixel signals in association with respective addresses, wherein said image sensor includes a plurality of light sensing cells each belonging to any of a plurality of groups, which are arranged in a two-dimensional array defined by a first direction and a second direction, said image sensor outputs said pixel signals which are obtained in said plurality of light sensing cells, some of said pixel signals obtained in some of said plurality of light sensing cells which belong to one of said plurality of groups are sequentially output in a reverse order to an order in which said some of plurality of light sensing cells are arranged in said two-dimensional array with respect to at least one of said first direction and said second direction, and said image processor comprises: a transfer part which collects pixel signals from light sensing cells of the same group in sets for each of the plurality of groups, each group is arranged such that each light sensing cell of a group does not directly adjoin another light sensing cell of the same group in the first or second direction in the two-dimensional array, the transfer part sequentially transfers said pixel signals which are collected in sets respectively for said plurality of groups and supplied from said plurality of light sensing cells in an order in which corresponding light sensing cells are arranged in either said first direction and said second direction of said two-dimensional array while manipulating said respective addresses, the transfer part including channel units which transfer pixel signals of the groups in parallel; a selector which sequentially selects pixel signals from each of the groups and outputs an output sequence of a plurality of said pixel signals according to an order in which corresponding light sensing cells are arranged in said image sensor, wherein each of the plurality of said pixel signals in said output sequence are obtained from a different light sensing cell of the plurality of light sensing cells and said output sequence includes a pixel signal from each of the plurality of light sensing cells of the image sensor; and a color interpolator which color interpolates said output sequence of the plurality of said pixel signals.
