Self\u2010powered photovoltaic operation further reduces the power demand of image sensing and processing. However, it remains challenging to achieve a continuously gate\u2010tunable self\u2010powered photovoltaic response that combines reversible polarity with linear weight programmability. Here, we demonstrate a gate\u2010tunable photovoltaic detector based on an NbS\n                    <jats:sub>3<\/jats:sub>\n                    \/WSe\n                    <jats:sub>2<\/jats:sub>\n                    van der Waals heterostructure. Owing to the ambipolar transport of WSe\n                    <jats:sub>2<\/jats:sub>\n                    and the distinct electrostatic responses of the two constituent materials, gate voltage continuously modulates the interfacial band alignment and reversibly switches the built\u2010in electric field at the heterointerface. Consequently, the device exhibits gate\u2010controlled positive and negative photovoltaic responses. The short\u2010circuit photocurrent scales linearly with incident power density, while the short\u2010circuit photoresponsivity varies linearly with gate voltage over a broad programming window. This dual linearity allows the photoresponsivity to function as a programmable analog weight for in\u2010sensor convolution. As a proof of concept, several image convolution kernels are implemented for in\u2010sensor image processing, and the experimentally obtained outputs agree well with algorithmic simulations. This work provides a promising device\u2010level building block for reconfigurable and energy\u2010efficient vision sensors for edge computing.\n
