Image processing apparatus and method, printed matter production apparatus and method, and printed matter production system

Abstract: An apparatus capable of converting motion image data, which is captured in an ordinarily way without intending to produce a parallax image printed matter, to data that can be printed as a parallax image printed matter is provided. The apparatus includes the steps of specifying at least one frame as a reference frame from a plurality of frames constituting the motion image data, and setting a point-of-regard on an object in the reference frame, calculating an amount of movement of the point-of-regard using a relation between the point-of-regard in the reference frame and a point corresponding thereto in another frame, obtaining a motion compensation amount for each frame based on this amount of movement thereof, and executing a motion compensation processing for the motion image data based on the motion compensation amount, thereby converting the motion image data to parallax image data.

System and method for transmitting data in frame format using an R-Rake retransmission technique with blind identification of data frames

Abstract: A system and method for effectively and efficiently retransmitting data frames, which were inadequately received by a receiver, back to the receiver for combination with the inadequately received data frames to increase gain at the receiver. The system and method preferably uses an R-Rake retransmission technique while eliminating the need to transmit a signaling message to a receiver for identifying the data frames to be combined as in the conventional R-Rake technique, and employs a data transmitter and a controller. The data transmitter transmits data in data frame format to be received by a receiver. Upon receiving a retransmission request from the receiver, the controller controls the data transmitter to retransmit a particular data frame to the receiver without transmitting a signaling message. The receiver receives the retransmitted data frame and compares it to other data frames stored in a buffer to determine the likelihood of a match between the transmitted data frame and a buffered data frame. When the likelihood of a match exceeds at least one predetermined threshold, the receiver combines the retransmitted data frame with the matching data frame, and provides the combined data frame to a higher layer in the receiver. However, if the likelihood of a match is below any of the predetermined thresholds, the receiver stores the either the combined data frame, or the retransmitted and matching data frame in the buffer, depending on which threshold the probability of a match is below, and sends another retransmission request to the transmitter to again retransmit the data frame. Accordingly, gain at the receiver can be increased without a substantial increase in signaling overhead.

Method and apparatus for determining flicker in the illumination of a subject

Abstract: A first image frame and a second image frame of an image are captured. A third image frame is formed from at least a portion of the first image frame and a corresponding portion of the second image frame. The third image frame is formed such that the effect of the subject or content of the image is reduced or negated in the third image frame relative to the level of flicker. A flicker pattern is detected using the third image frame. Various techniques are described to capture the second image frame, and for determining the flicker pattern from the third image frame. The flicker pattern may be used to avoid or remove flicker from one or more images, or to correct a captured image.

Image correspondence techniques using serial neighborhood processing

Abstract: A serial neighborhood processing system, preferably employing a pipeline of individually programmable stages, is used to detect image correspondence between multiple frames of image data. Similar features in each frame are extracted utilizing a series of dilation and erosion sequences. In particular, landmarks in each frame are condensed to single image points having exactly one corresponding point in the other frame surrounding it within a given mathematical distance. The second frame of pixel data is registered with the first frame as a function of the spatial relationship between these pairs of matched points in the two reduced frames. A comparison is made between the first frame and the registered second frame to detect differences therebetween. Motion detection, stereo projection, registration of multidate Landsat imagery and matching images of electrophoretic gels are examples of particular uses for the techniques disclosed.

Framing circuit for digital system

Abstract: A framing system processes a digital signal having a clock period of T seconds and a frame of which is made up of an n-bit framing pattern and m-bit information, (n+m) bits long in total. This system is applicable to a situation in which the probability that a pattern common to the n-bit framing pattern appears in the m-bit information is very low. With attention paid to the special characteristics of a frame pattern, when a coincidence pulse is found at a position different from the present frame position inside a window, the frame information is immediately regarded as being lost at that instant and the system is caused into a hunting state to search a new frame position.
