Abstract: An overlay welding method includes irradiating a surface of a metal member with a laser beam while supplying a weld metal powder, and performing overlay welding on the surface of the metal member, and repeatedly performing a weld bead formation step of melting and solidifying the weld metal powder with the laser beam to form a plurality of weld beads on the surface of the metal member. Each of the plurality of weld beads has one portion in a width direction overlapping each other. In the overlay welding method, in a case of forming an adjacent weld bead, which is a weld bead adjacent to a previously formed weld bead, an energy density of the laser beam is adjusted to be higher at a portion of the adjacent weld bead overlapping the previously formed weld bead than at a portion not overlapping the previously formed weld bead.

Abstract: Moving images are coded with reduced deterioration in the image quality while variations in the amount of code per frame are being reduced. A moving image coding apparatus includes a remaining picture number obtaining unit, an activity calculation unit, an intra MB determination unit, and a coding unit. The remaining picture number obtaining unit detects the temporal position of the current frame image, and determines the reset timing at which an intra refresh process is reset in a manner that the reset timing differs for each macroblock line (MBL). The activity calculation unit calculates an activity value for each macroblock (MB). The intra MB determination unit determines a MB to be set as an intra MB based on the activity value calculated by the activity calculation unit. The coding unit codes the MB set as an intra MB through an intra coding process.

Abstract: A moving image coding apparatus, a code amount control method, and a code amount control program enable appropriate code amount control to be performed in units shorter than frames. The moving image coding apparatus includes a coding unit, a quantization parameter determination unit, and a target code amount setting unit. The target code amount setting unit designates the number of macroblocks and sets a target code amount as a code amount to be allocated to the designated number of macroblocks. The quantization parameter determination unit calculates, for each macroblock, a quantization parameter to be used in quantization of a current macroblock based on a sum of absolute transformed differences SATD used in a motion estimate process. The moving image coding apparatus performs quantization using the calculated quantization parameter value.

Abstract: In an image coding apparatus (1), a Hadamard transform unit (11) performs horizontal Hadamard transform on a picture of uncompressed image data (21). The sum total of absolute values of AC component values obtained by the Hadamard transform is calculated as a Hadamard value (23) of the picture. A scene change determination unit (12) determines whether a scene change occurs or not in the picture on the basis of the Hadamard value (23). In a case where a scene change occurs in the picture or where a differential absolute value between the amount of generated codes in a coded GOP and the ideal amount of codes in a GOP is larger than a predetermined reference value, a quantization parameter determination unit (13) determines a quantization parameter (24) of the picture on the basis of the Hadamard value (23) and the target amount of codes of the picture. A coding unit (14) codes the picture by using the determined quantization parameter (24).
