An image processing apparatus of the disclosure includes: a blocking unit configured to divide image information into blocks; a map information acquisition unit configured to acquire at least one piece of map information in which pieces of reference pixel information and pieces of positional information are associated with a target pixel in each of the blocks, the pieces of reference pixel information denoting at least one reference pixel referenced by the target pixel, each of the pieces of positional information denoting a positional relationship between the target pixel and the at least one reference pixel; and a reference pixel information selecting unit configured to select one piece of reference pixel information of the pieces of reference pixel information included in the at least one piece of map information based on a pixel value of the target pixel and a pixel value of the at least one reference pixel.

Image processing apparatus, image processing method, and image processing program

A method of automatically controlling a transmission power of a wireless communication apparatus that reduces power consumption and adjusts the transmission power to enable communication to be carried out at an optimum transmission power, and a storage medium which stores the method are provided. At a start of communication, a wireless communication apparatus performs communication while setting the transmission power to the maximum value. Each time when transmission succeeds, the transmission power is reduced by a predetermined amount. When transmission fails as a result of the reduction by the predetermined amount, retransmission is carried out with increasing the transmission power by the predetermined amount. The increased power is set as an optimum transmission power. The power is maintained until transmission fails. When transmission fails after the optimum transmission power is set, transmission power is raised to the maximum value and setting of optimum transmission power is again carried out.
