Abstract
An image processing apparatus is disclosed that includes a characteristics acquisition unit that acquires characteristics of a picture image; a format selection unit that selects the format of image data depending on the processing time for restoring the picture image based on the characteristics; and a format conversion unit that converts the format of the image data into that selected by the format selection unit.
Claims15
An image processing apparatus comprising:
- a characteristics acquisition unit to acquire transformation coefficients generated by an orthogonal transformation process of a picture image;
- a format selection unit to select either a raster data format or a vector data format by comparing an average of the transformation coefficients with a given threshold;
- and
- a format conversion unit to convert the format of the image data into the format selected by the format selection unit.
