Title: SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD AND COMPUTER PROGRAM
Abstract:
[Problem] To provide a signal processing device which is capable of shortening processing time without degrading dynamic range performance or flexibly adjusting a tradeoff between image quality and processing time upon receiving an HDR image. [Solution] Provided is a signal processing device provided with: a synthesis processing unit which synthesizes, at least (N-1) times, an image of N frames which have exposure times that are different from each other; and a motion adaptation processing unit which performs a motion adaptation process in one-time synthesis that uses two of the group of the images in the synthesis processing unit, wherein the number of motion adaptation processes in the motion adaption processing unit is equal to or less than (N-2), when the synthesis processing unit performs the synthesis (N-1) times.
