摘要: An imaging apparatus, such as used in a digital camera or scanner, includes at least one photosensor chip. Each chip includes one line for conveying a signal causing an integration event of a selected subset of photosensors on the chip, the integration event being one of a starting or ending an integration period for the subset of photosensors. Each chip also includes at least two selection lines, for conveying a multi-bit code identifying the selected subset of photosensors for the integration event.

摘要: A photosensor chip, such as used in a hard-copy scanner, reads out image data in repeated cycles. With each cycle an on-board counter counts to a predetermined number and resets to zero. When the clock count reaches certain numbers, integration events are initiated with regard to different subsets of photosensors on the chip. The start and stop times of the integrations within each cycle can thus be adjusted via software instructions.

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: In an imaging apparatus such as a scanner or digital camera, a plurality of photosensors read image data onto a video line. The video line is periodically associated with a correction signal of predetermined magnitude, such as on a correction capacitor on the video line. A digital-analog converter (DAC) precisely adjusts the correction signal, to make consistent the video outputs of different subsets of photosensors on a chip, or of different photosensor chips reading onto a single video line.

摘要: An imaging apparatus, such as used in a digital camera or scanner, includes at least one photosensor chip. The chip includes subsystems thereon that control the integration periods of the photosensors according to different control data formats. A selector is used to adapt the chip to accept control data of a selected format consistent with a larger apparatus or system.

摘要: An imaging apparatus, such as would be used in a digital copier, includes at least one linear array of photosensors. Along a direction of the array, the photosensors are filtered to different primary colors, such as RGB, according to a repeating pattern. The repeating pattern includes at least one substantially clear photosensor, or a photosensor sensitive to a non-primary color (K). Some possible repeating patterns thus include RGBK, RKB, BKRK, and RGBGKG.
