Image acquiring apparatus and method and image forming apparatus

An image acquiring apparatus comprising:

• a memory;
• and
• a processor coupled to the memory, the processor to,
• in response to an instruction to acquire a single-side image formed on a first surface of a document,
• control acquiring, by a first image sensor, the single-side image and acquire, by a second image sensor as a penetrated image sensor, a penetrated image of same single-side image shown through a second surface of the document, while the document is being fed;
• and
• perform an image process on the single-side image, based on the acquired penetrated image of the same single-side image shown through the second surface of the document,
• wherein,
• the acquiring of the penetrated image includes determining whether the penetrated image is a text image or a picture image, and
• the image processing of the single-side image includes sharpening the single-side image when the penetrated image is the text image.
