An imaging device includes an imaging unit capturing an image of a subject, and tracks, through images captured in time series, an area in which a specific target appears. The device includes a parameter acquiring unit acquiring a photographic parameter from the imaging unit, a target area determining unit determining an area of a captured image including the specific target as a target area, a track area adjusting unit setting a track frame for a track area to track the target area including the specific target and adjusting a size of the track frame based on the photographic parameter, and a track area searching unit searching the captured image for the track area, while moving the size-adjusted track frame, based on a similarity between a characteristic amount of the track area of a current captured image and that of the target area of a previous captured image.

An image processing apparatus that detects a face area from image information includes a pattern database, a face-direction determining unit, and a face-area detector. The face-direction determining unit determines, as a face direction, a direction in which a face image in image information is upright based on determination pattern information stored in the pattern database. The face-area detector matches the direction of the image information with the direction of the determination pattern information based on the face direction, and detects a face area from the image information.

An image-information acquiring unit acquires image information. A component separating unit separates the image information acquired into luminance information and color information. A luminance-component-noise removing unit removes noise from the luminance information using a first noise removing method. A color-component-noise removing unit removes noise from the color information using a second noise removing method different from the first noise removing method used in the luminance-component-noise removing unit.

An image processing unit is disclosed that smoothens a notice pixel of input image data with pixel values of pixels around the notice pixel to reduce noise in the image data. The image processing unit includes an edge extraction unit that extracts an edge based on the pixel values of the image data; a region determination unit that determines a region to be processed where a sum of edge intensities of the pixels including the notice pixel becomes greater than or equal to a threshold; and a smoothening unit that changes a smoothening intensity in accordance with a size of the region to be processed to smoothen the notice pixel corresponding to the region to be processed.

An image correcting apparatus is provided for preventing a degraded image quality which can be caused by a three-dimensional distortion correction made to a scanned image distorted in a trapezoidal shape. Divergent distortion angles α, β of a scanned image are detected using a page contour of a book document which can be found near the upper or lower edge of the scanned image in a main scanning direction. The scanned image is corrected for a divergent distortion based on the divergent distortion angles α, β, followed by a correction of the scanned image for a shape distortion in a sub-scanning direction. In this way, the image quality can be prevented from degradation possibly caused by the three-dimensional distortion correction, if made to such a scanned image distorted in a trapezoidal shape.

A 3-D visual simulating system stores image data sets in a predetermined viewing space for right and left visual field and selects a portion of the stored image data corresponding to the current visual field for displaying it to an observer. The 3-D image stimulus changes according to the current visual field of the observer and the location of the observer in a predetermined visual space in a manner that undesirable perceptional effects are substantially eliminated. The image data sets are stored in a reduced space in an efficient manner for retrieval.

An image processing apparatus includes a first pattern detecting mechanism, a memory, and a pattern identity determining mechanism. The first pattern detecting mechanism detects a background dot pattern embedded in a background image included in image data of an original image from the image data. The memory stores an anti-copy background dot pattern. The pattern identity determining mechanism compares the detected background dot pattern with the anti-copy background dot pattern stored in the memory and determines that the detected background dot pattern is substantially identical to the anti-copy background dot pattern stored in the memory.

A projector is often positioned so that its optical axis is at an imperfect orthogonal angle with respect to a projection screen. This position causes a keystone distortion as well as imperfect focus in the projected image. To correct these undesirable problems, initially, a lens and/or an image-forming plate is independently repositioned to bring the projected image into focus based upon user input data. The keystone distortion is also corrected by redrawing the image on an image-forming surface based upon additional user input data.
