    摘要: A color chip construction (5) especially adapted for use in fabricating full-width arrays, in which the individual chip photosites consist of three complementary color (blue, green, and red) photodiodes (32, 34, 36) shaped and positioned to provide a rectangular photosite (12) with perpendicular edges that enhance butting of like color chips together to form full-width color arrays.

    摘要: A photosensitive imaging apparatus has a linear array of groups of photosensors. In a low-resolution scanning mode, all of the photosensors in each group act together as one large photosensor. In a high-resolution scanning mode, each photosensor in a group acts outputs image-based signals independently. In either mode, the signals output by the photosensors are transferred to one of two output lines, such as for "odd-" and "even-" positioned photosensors or groups of photosensors. The signals on the two lines can then be multiplexed to a single output line. The dual output lines enable fast signal output in either resolution mode.

    摘要: A CMOS-based photosensor array, having a plurality of photodiodes (10) therein, includes a spillover protection circuit (30) associated with each photodiode (10). The spillover protection circuit (30) causes a potential to be applied to a photodiode (10) in response to a charge spillover or "blooming" condition. The spillover protection device (30) is momentarily disabled whenever a bias charge (VFZ) is injected onto the photodiode (10) by the transfer circuit (12). Also, a reference voltage applied to the gate of a transistor forming the spillover protection device (30) is higher than a threshold voltage of the transistor but is lower than a sum of the threshold voltage and a maximum light-intensity signal from the photodiode (10).
