Abstract: An information processing apparatus and an image processing method are provided. The image processing apparatus detects character data from image data, executes edge enhancement processing, using a first filter, on an edge portion of a region, out of the detected character data, that includes a region whose frequency of points or lines is greater than a predetermined frequency, and executes edge enhancement processing, using a second filter, on an edge portion of a region, out of the detected character data, that does not include a region of a spatial frequency higher than the predetermined frequency. The first filter has, in comparison to the second filter, a larger degree for edge enhancement with respect to a region having a frequency higher than the predetermined frequency.

Abstract: An image processing apparatus capable of communicating with a server that provides a microblogging function detects a registration of a first message to the server, acquires image data indicated by the first message whose registration is detected, outputs the acquired image data and registers to the server a second message on the first message registered to the server, in a case where the image data is not output within a predetermined time period.

Abstract: An image processing apparatus includes a first determination unit configured to determine whether a pixel included in image data belongs to an edge, a second determination unit configured to determine whether a pixel included in the image data is achromatic, and a processing unit configured to perform process for forming a pixel only with an achromatic color material on a pixel determined as belonging to an edge and being achromatic. In a case where the pixel has been determined as belonging to an edge and being achromatic, the processing unit determines whether the process is to be performed on a pixel adjacent to the pixel which has been determined as belonging to an edge and being achromatic, and, in a case where it has been determined that the process is to be performed, performs the process on the adjacent pixel.
