Systems and methods for processing image data prior to compression
First Claim
Patent Images
1. A system for processing an image for compression and transmission, the image having data associated therewith, the data having one or more data values and color levels, the data being subsequently compressed and transmitted, the system comprising:
- a parameter selecting circuit, routine or application that determines one or more parameters for processing data associated with the image, the parameters associated with at least one of data compression and data transmission of the image,wherein the parameter selecting circuit, routine or application determines at least one of a bandwidth of a network for subsequent data transmission, a transmission speed of the network, a data display zoom level, and a compressed image size;
a data enhancing circuit, routine or application that enhances a contrast of the data values, prior to compressing the processed data, based on the one or more parameters determined; and
a data compression circuit, routine or application that compresses data processed by the data processing circuit,wherein the data processing circuit, routine or application increases a data compression ratio in the data compression.

11. A computer-readable medium storing a computer program product tangibly embodying a program of instructions for processing an image for compression and transmission, the image having data associated therewith, the data having one or more data values and color levels, the instructions, when executed by a processor, causing the processor to perform operations comprising:
-
determining one or more parameters associated with at least one of data compression and data transmission of the image; processing data associated with the image by enhancing a contrast of the data values, prior to compressing the processed data, based on the one or more parameters determined, wherein processing the data associated with the image comprises using tonal reproduction curves to increase a number of correlated entries in the data, thereby increasing a data compression ratio in subsequent data compression; and compressing the processed data associated with the image. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method for processing an image for compression and transmission, the image having data associated therewith, the data having one or more data values and color levels, the method comprising:
- using a controller, the controller;
determining one or more parameters associated with at least one of data compression and data transmission of the image; processing data associated with the image by enhancing a contrast of the data values, prior to compressing the processed data, based on the one or more parameters determined, wherein processing the data associated with the image comprises using tonal reproduction curves to increase a number of correlated entries in the data, thereby increasing a data compression ratio in subsequent data compression; and compressing the processed data associated with the image. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
