Zusammenfassung:	In a general aspect, a camera can include a dynamic memory, and a software driver configured to store, in the dynamic memory, a plurality of predetermined lookup tables (LUTs), and to issue an interpolation command indicating a value of a quantitative image factor corresponding with an image frame received by the ISP. The camera can also include a LUT processing circuit configured to receive the interpolation command, and in response to receiving the interpolation command: read a first predetermined LUT and a second predetermined LUT from the dynamic memory; and perform at least one interpolation operation to generate an interpolated LUT. The camera can further include an image signal processor (ISP) including a configuration register, and the LUT processing circuit can be configured to write the interpolated LUT to the configuration register.
