“…It removes correlation between neighboring pixels. The simplest lossless predictive coding scheme, the gradient-adjusted prediction (GAP) integrated with image-sensor array is first proposed in [51]. The mean value of the upper and the left neighbors are used as the predictive pixel value X. Pixels in the first row and first column are not predicted.…”

Demand for high-resolution, low-power sensing devices with integrated image processing capabilities, especially compression capability, is increasing. CMOS technology enables the integration of image sensing and image processing, making it possible to improve the overall system performance. This paper reviews the current state of the art in CMOS image sensors featuring on-chip image compression. Firstly, typical sensing systems consisting of separate image-capturing unit and image-compression processing unit are reviewed, followed by systems that integrate focal-plane compression. The paper also provides a thorough review of a new design paradigm, in which image compression is performed during the image-capture phase prior to storage, referred to as compressive acquisition. High-performance sensor systems reported in recent years are also introduced. Performance analysis and comparison of the reported designs using different design paradigm are presented at the end.

“…The prediction residual is further encoded through the entropy coder. A number of papers have sought to integrate the predictive coding methods with an off-array processor, such as gradient-adjusted prediction (GAP) [22], FELICS [23] and LOCO-I [24,25]. The work in [26] proposes to implement an adaptive quantization scheme based on the fast boundary adaptation rule followed by quadrant tree decomposition.…”
