Abstract: A method (200) and an apparatus (500) for compensating for brightness of a display panel (140), and a display device (100) are provided. The method (200) for compensating for brightness of a display panel (140) includes: timing a vertical blanking interval (Vblank) in a current frame on the display panel (140) (202); and determining, in response to that a timing time of the vertical blanking interval (Vblank) reaches a first threshold time, a first value used to perform first compensation on brightness of the display panel (140) during the vertical blanking interval (Vblank) in the current frame (204). According to the method (200) for compensating for brightness of a display panel (140), a brightness change caused by current leakage can be compensated for by adjusting a related analog voltage in a timely manner.

Abstract: This disclosure discloses image sensors, signal processing methods, and related devices for image processing. An example image sensor comprises an optical filter array. The optical filter array is a hyper spectral or multispectral optical filter array and comprises m optical filters and an optical-to-electrical conversion module. The optical-to-electrical conversion module comprises an optical-to-electrical conversion unit and a combining unit. The m optical filters are configured to obtain optical signals of a target object in at least two different spectral bands. The optical-to-electrical conversion unit is configured to convert the optical signals obtained by the m optical filters into electrical signals. The combining unit is configured to combine the electrical signals corresponding to the m optical filters to obtain a combined electrical signal. The optical-to-electrical conversion module is configured to output the combined electrical signal, which is used to generate an image of the target object.
