发明名称 Method of and apparatus for processing an image according to a correction level.
摘要 Tone correction for input video signals is performed by use of look-up table data. The degree of color correction level is decided by using chroma signals (17R, 17G, 17B) each corresponding to a respective one of input video signals and a luminance signal (27) of the input video signals. In response to the particular level decided, signals (35R, 35G, 35B) are produced by applying color correction level adjustment to the individual input video signals. A highlight and a shadow point are set up based on a respective one of such adjusted signals (35R, 35G, 35B) so as to produce look-up table data for each of the input video signals. This allows input video data to be subjected to tone correction which matches with particular photographing conditions, thereby eliminating overcorrection. Hence, the operator's decision as to the degree of correction is needless so that the ease of operation is promoted.
