Conventional photodetection systems typically rely on external filters or post\u2010processing to resolve spectral information, leading to increased system complexity and data transfer overhead. Here, we report a reconfigurable photodiode based on spatially patterned doped tungsten diselenide (WSe\n                    <jats:sub>2<\/jats:sub>\n                    ), which exhibits two runtime switchable photodetection modes and a bidirectional wavelength\u2010dependent conductance modulation across the visible spectrum. Under a broadband photodetection mode, the device exhibited a fast response and a high linear dynamic range of 72\u00a0dB. Meanwhile, under color\u2010filtering mode, the device enables nonvolatile and color\u2010selective detection spanning from 445 to 780\u00a0nm, to experimentally achieve the in\u2010sensor spectral processing, including color\u2010based logic operations and object trajectory recognition within the visible wavelength range. We further demonstrate its application in encrypted information identification using chromatically encoded digit patterns, where the device selectively decodes multicolor information via bias\u2010controlled readout. Simulation results confirm high classification accuracies of approximately 98.99% for red and 98.76% for green patterns using a standard convolutional neural network, highlighting the potential of this platform for hardware\u2010level spectral\u2010domain information processing with reduced system complexity.\n
