Abstract

An image processor includes an extracting unit and a synthesizer. The extracting unit extracts partial image data corresponding to a set color from pickup image data of first to (N−1)-th frames of the first to N-th frames output from an image pickup unit within one video recording cycle. The extracting unit estimates a region-to-be-extracted based on a color of a pixel from pixels constituting the first to (N−1)-th frames, stores pixel values of pixels included in the estimated region-to-be-extracted, determines validity of the estimated region-to-be-extracted, and stores, in a storage unit, region information of the region-to-be-extracted that is determined as being validated. The synthesizer synthesizes the pixels of the region-to-be-extracted and the pickup image data of the N-th frame based on the region information to generate and output an output frame.

First claim

What is claimed is:

1. An image processor, comprising:
an extracting unit that extracts partial image data corresponding to a set color from pickup image data of first to (N−1)-th frames of the first to N-th frames output from an image pickup unit within one video recording cycle, where N is an integer not less than two;
a storage unit coupled to the extracting unit to store the extracted partial image data; and
a synthesizer coupled to the storage unit, wherein the synthesize…
