The first flexible circuit board has a plurality of first coil windings and a first Hall sensor. The plurality of first coil windings actuates the lens unit along an optical axis. An image stabilization actuator includes an image stabilization carrier having a plurality of magnets facing the first coil windings and a second flexible circuit board having a plurality of second coil windings facing respective lower surfaces of the magnets and a second Hall sensor. The camera lens module includes a base coupled with the image stabilization actuator under the image stabilization actuator, and a plurality of rollers disposed on the base and configured to rollably move the image stabilization actuator.

An image processing device including a blurring processing unit that performs blurring processing for input image information that is input, includes: a saturation determination unit that calculates saturation of a saturated pixel of the input image information; a first gradation conversion unit that converts gradation of the input image information on a basis of the saturation calculated by the saturation determination unit; and, in which the blurring processing unit performs blurring processing for image information that has been subjected to gradation conversion by the first gradation conversion unit, a second gradation conversion unit that converts gradation of image information that has been subjected to the blurring processing, on a basis that gradation of a saturated region of the blurring-processed image information serves as a gradation of a saturated pixel.

An image sequence includes consecutive video images each exhibiting at least one image region having a number of pixels, where each pixel includes at least one intensity value. For each image a motion measure value is determined indicative of temporal change of a video content of the image region and varying the intensity values of the pixels of the image region relative to the associated intensity values from video image to video image, a measure for the variation of the intensity values being dependent on the motion measure value determined and the change in the intensity values relative to the associated intensity values being greater the larger the motion represented by the motion measure value.

A blurless image capturing system sequentially acquires images with little blur, even in a situation where a camera moves. An image capturing camera unit and a mirror unit are both capable of continuous movement in at least a one-dimensional direction. The image capturing camera unit acquires an image of a physical object present within an object region by directing line of sight direction towards the object region by means of the mirror unit. The mirror body changes the line of sight from the image capturing camera unit. The drive unit changes an angle of the mirror body in a given angular velocity in accordance with movement of the image capturing camera unit and the mirror body In this way it is possible to keep the line of sight from the image capturing camera unit directed towards a physical object for a given time. The drive unit directs the line of sight from the image capturing camera unit towards another object region by driving the mirror body. The control unit controls operation of the drive unit.
