Abstract
The invention relates to image sensors using a chip with cut corners. The sensor comprises a chip with cut corners comprising a matrix (10) of horizontal lines and vertical columns of photosensitive members, the matrix having a generally rectangular shape of horizontal width W and having four bevels, the sensor comprising as many current or voltage read blocks as there are matrix columns, in order to read the image signals detected by the photosensitive members, characterized in that the current or voltage read blocks are placed in a row (30, 30′) along a horizontal edge of the matrix of width W′ and are all housed within a vertical strip, the width W1 of which is substantially less than the maximum width W of the matrix. There are two superposed rows of current read blocks with blocks distributed at the same pitch as the pixel columns, or there is a single row with read blocks distributed with a pitch less than that of the pixel columns. The invention can be applied to CMOS technology intraoral radiological sensors.
