Abstract: A defective pixel correction device is provided. The defective pixel correction device includes: a pixel grading circuit configured to output a grade map including a plurality of grades indicating defect levels and respectively corresponding to a plurality of pixels included in an input image; a pixel selection circuit configured to select one or more candidate pixels from among the plurality of pixels, based on whether the plurality of grades correspond to a correction level, in the grade map; and a correction circuit configured to correct the one or more candidate pixels.

Abstract: An image signal processor includes a command queue circuit, an image processing engine and an interrupt control circuit. The command queue circuit stores a plurality of commands and sequentially provides the plurality of commands one by one. Each command of the plurality of commands includes an interrupt control value corresponding to each image unit of a plurality of image units. The plurality of commands are received from a control processor. The image processing engine receives the plurality of image units and sequentially processes the plurality of image units based on the plurality of commands sequentially provided from the command queue circuit. The interrupt control circuit receives the interrupt control value from the command queue circuit, determines one or more output interrupt event signals among a plurality of interrupt event signals based on the interrupt control value and generates an interrupt signal based on the output interrupt event signals.
