Image inputting apparatus, method, and storage medium recording image inputting program

Abstract

A controlling unit of an image inputting apparatus increments a counter each time an instruction to start an image input is externally provided. An image compressing unit waits for the completion of the storage of an entire image in a buffer memory, and issues an instruction to detect the state of the image to an image state detecting unit. The image state detecting unit detects the rotation direction and the presence/absence of mirror-reversing of the image stored in the buffer memory, and notifies the detection result to an image compressing unit. The image compressing unit switches a scanning order of pixels to be read from the buffer memory based on the notification, compresses the image data while reading the image data in the switched scanning order, and stores the compressed image data in a data storing unit. After the entire image data within the buffer memory is stored in the image data storing unit, the lastly stored image data is decompressed by an image decompressing unit, and the decompressed image is displayed on a display.
