Problems solved by technology

This means that the graphic data after line #k in the graphic data area 12 is insufficient for the subsequent compensation
[0016] As mentioned above, a CMOS sensor that attempts to do hand shake compensation without touching the limits of the compensation cannot provide complete graphic data after compensation
The resulting graphics are easily deformed, creating an inconvenient and uncomfortable impression for viewers

Abstract

The invention discloses an image processing device, comprising: an imaging unit that acquires a graphic of an object using an image pickup device; a graphic storage unit that stores the acquired graphic; a vibration detection unit; a compensation amount calculation unit that calculates a compensation amount required to eliminate the influence of the vibration on the imaging unit according to the vibration amount; a change amount calculation unit that calculates a change amount of the compensation amount between predetermined positions; determines the change amount a compensation limit determination unit that exceeds a limit available for compensation of a pattern stored in the pattern storage unit; a compensation amount adjustment unit that adjusts the compensation amount according to whether or not the compensation limit is exceeded before outputting the adjusted compensation amount; and based on the adjustment by the compensation amount The adjusted compensation amount output by the unit corrects the graphic correction unit of the graphic stored in the graphic storage unit.

Description

technical field [0001] The present invention relates to an image processing device. More specifically, the present invention relates to an image processing device for calculating a compensation amount for the influence of vibration, a method for causing the device to perform such calculation, and a program for causing a computer to execute the method. Background technique [0002] Camcorders are widely used today. These cameras generally include a charge transfer type solid-state image pickup device exemplified by a CCD (Charge Coupled Device) sensor or an X-Y address type solid-state image pickup device represented by a CMOS (Complementary Metal Oxide Semiconductor) sensor. [0003] Driven by a single low voltage, CMOS sensors consume less power than CCD sensors and are better suited for integration with its peripheral circuits. These advantages have prompted researchers to consider CMOS sensors for image processing devices such as video cameras. [0004] However, it has...
