  • Publication number: 20200376678
    Abstract: A visual servo system includes a robot that handles an object, an irradiation device that irradiates light onto the object, and a camera that captures an image of the object and outputs a current image. The visual servo system reads, from a storage medium, a target image that is assumed to be captured by the camera when the object is in target position and attitude, and the light irradiated from the irradiation device is striking the object. The visual servo system calculates control input to be inputted to the robot based on a difference in luminance value between the current image and the target image, and inputs the control input to the robot. The light that is irradiated by the irradiation device is light that has a luminance distribution based on a reference image in winch a luminance value changes along a predetermined direction.

  • Patent number: 9921481
    Abstract: The present invention provides a composition enabling to form a fine negative photoresist pattern free from troubles such as surface roughness, bridge defects or unresolved defects, and the invention also provides a pattern formation method employing that composition. The composition is used for miniaturizing a resist pattern by applying to a negative resist pattern from a chemically amplified resist composition and fattening the resist pattern. This composition comprises a polymer comprising a repeating unit having an amino group or a polymer mixture, and a solvent, and further comprises a specific amount of an acid or indicates a specific pH value. The polymer mixture comprises polymers whose HSP distance, determined from Hansen solubility parameter, is 3 or more. In the pattern formation method, the composition is cast on a negative photoresist pattern beforehand obtained by development with an organic solvent developer and is then heated to form a fine pattern.

  • Patent number: 8416850
    Abstract: When entropy-encoding a converted quantized amount obtained by converting an image into a frequency region and quantizing it, if the output code bit quantity of the entropy encoding exceeds a predetermined amount, an image obtained by rebuilding the converted quantized value is outputted from an image encoding device. This guarantees an encoding delay caused by re-encoding to be a constant time without increasing the circuit size of the encoding device and provides an image encoding device of a subjectively high quality.

  • Patent number: 6574277
    Abstract: Distance from a small block to a synchronizing pattern inserted into coded data is calculated for each small block in an image frame. On the basis of the count, a data-loss probability estimation unit estimates the probability that coded data of a target small block will be lost during transmission. In regard to a small block in which interframe predictive coding has been performed, an image-quality degradation estimation unit estimates the degree of image-quality degradation that will be caused in this small block in the decoded image. The forced refresh priority of each small block is calculated upon comparing the estimated data-loss probability and estimated degree of image-quality degradation with threshold values, and the values of priority are recorded in the form of a forced refresh map. When the next frame is coded, reference is had to the recorded values of priority and a small block in which intraframe coding will be forcibly performed is selected based upon the recorded values of priority.

  • Patent number: 6473207
    Abstract: In an image size transformation method for an orthogonal transformation coded image, orthogonal coefficients as coded data of an image are read out by blocks, after which an operation process for transforming the coefficients on the orthogonal coefficients is carried out. Due to this operation process, coefficients of Y blocks are obtained from coefficients of X blocks, by which the orthogonal coefficients after having the image size enlarged or reduced are outputted. Due to this structure, it is possible to simplify the decoding system. According to the image size transformation method of the present invention, orthogonal transformation coefficients are processed directly on the coefficients by which a transformation of high precision is possible, while there is no possibility that a transformation efficiency will deteriorate because of operation errors caused by inversion or filtering, as in the conventional case.
