Method for compressing image data collected by camera and electronic device for supporting the method

摘要

A technique is provided to allow an optimal image data compression by compressing image data, collected by a camera, on a more suitable compression condition. In a method for compressing image data, an electronic device generates preview data of an original image collected through the camera, calculates a first compression ratio based on analyzing complexity of the preview data relating to pixel distribution of the original image, and compresses a capture image, selected in response to a capture command, corresponding to the preview data on the basis of the calculated first compression ratio.

1. A method for compressing image data of a camera, the method comprising:
generating preview data of an image collected through the camera, wherein the preview data is generated from the collected image without further encoding; determining a first compression ratio through analyzing complexity of the preview data; and compressing a capture image as a function of the determined first compression ratio, wherein the capture image corresponds to the preview data selected in response to a capture command for capturing the collected image, wherein determining the first compression ratio comprises determining a compression ratio for each object contained in the preview data by referring a Q table, the Q table comprising compression ratios of the objects.
