Problems solved by technology
When the camera module supports higher image resolution, the camera data transmitted through the camera interface will have a larger data size / data rate, which will inevitably increase the power consumption of the camera interface
If both the camera module and the host application processor are located in a battery-powered portable device (such as a smartphone), the battery life will be shortened due to the increased power consumption of the camera interface

Embodiment Construction
[0036] Certain terms are used throughout the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" here includes any direct and indirect electrical connection means. Therefore, if it is described in the text that a first device is coupled to a second device, it means that the first device can be directly electrically connected to the second device. device, or indirectly electrically connected to the second device through other devices or connection means.

An image encoding method includes at least following steps: receiving a plurality of target pixels within a frame, wherein pixel data of each target pixel has at least one color channel data corresponding to at least one color channel; determining a bit budget of the target pixels; and performing bit-plane scanning coding upon selected pixels according to the bit budget and a scanning order, and accordingly generating encoded pixel data of the selected pixels as encoded data of the target pixels, wherein the selected pixels are derived from the target pixels, and the bit-plane scanning coding extracts partial bits of pixel data of each selected pixel as encoded pixel data of the selected pixel. In addition, a corresponding image decoding method is provided.
Description
[0001] cross reference [0002] The present invention claims priority of U.S. Provisional Application No. 61 / 774,811 (filing date March 8, 2013), and claims priority of U.S. Application No. 14 / 183,537 (filing date February 19, 2014), and the above application The entire contents of the case are incorporated by reference. technical field [0003] The embodiments disclosed in this application are related to image coding and decoding, more specifically, to an image coding method and device for performing bit-plane scan coding based on pixel data, and a related image decoding method and device. Background technique [0004] A display interface is provided between the first chip and the second chip to transfer display data from the first chip to the second chip. For example, the first chip can be a host application processor (host application processor), and the second chip is a driver integrated circuit (IC). The display data includes image data, video data, graphic data, and...
