Title: Image pickup device
Inventor: KAWAHARA HIDEO
IPC: H04N5/232
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To obtain an image with less color slurring and without a shape at a still image photographing mode by permitting the output of a still image by means of an image pickup element only when correction quantity is less than a specified value. SOLUTION: When correction quantity exceeds the threshold 73 of angular displacement when a dynamic image is taken, a panning.tilt judgment circuit judges panning or tilting. A characteristics is changed so that a blur correction system does not make a response to the frequency of a low band. Namely, still image recording is permitted when a threshold 74 for judging recording start when optical axis correction quantity 72 is lower than the threshold 74 (side where correction quantity is small), and still image recording is not executed when it is upper than a dot line (side where correction quantity is much). The recording of the still image is started when an area 76 with large optical axis correction quantity 72 becomes an area 77 with small optical axis correction quantity. Thus, the image with less color slurring and without the shape can be recorded at the time of switching the mode to still image photographing mode.
