Patent ID: 7349585

Claim:
A server-client system, comprising: a server computer; and a client computer to display an image processed by and received from the server computer, the client computer connected to the server computer via a network, wherein the client computer comprises: a generation unit to generate a test image of a predetermined region of an original image using a certain resolution and to transmit the generated test image to the server computer; a determination unit to receive a confidence level associated with OCR processing from the server computer and to determine whether the confidence level satisfies a predetermined condition; and a resolution change unit to generate an additional test image using a different resolution and to transmit the additional test image to the server computer, and wherein the server computer comprises: a confidence level computation unit to decompress the test image received from the client computer, to perform OCR processing on the decompressed test image and to compute the confidence level associated with the result of the OCR processing; a confidence level transmission unit to transmit the confidence level associated with the OCR processing computed by the confidence level computation unit to the client computer; and an OCR result transmission unit to decompress the test image received from the resolution change unit of the client computer, to perform OCR processing on the decompressed test image, and to transmit the result of the OCR processing to the client computer; wherein, if the confidence level received from the server computer is higher than a predetermined level, the client computer transmits an additional test image of a lower resolution to the server computer, and if the confidence level received from the server computer is lower than the predetermined level, the client computer transmits an additional test image of a higher resolution to the server computer.
