TechInsights has just received the Motorola Moto X30 Pro (XT2241-1) smartphone and launched an analysis on its wide-angle rear camera, confirming the Samsung HP1.

The HP1 is a 200 MP, 0.64 µm pixel-pitch stacked, back-illuminated ISOCELL CMOS Image Sensor (CIS). The HP1 represents Samsung’s 3rd sensor observed by TechInsights with a 0.64 µm pixel-pitch, following the 50 MP JN1 and JNV sensors. The HP1 sensor measures 11.83 mm x 8.97 mm, with a pixel array of 10.58 mm x 7.96 mm giving an active area diagonal of 13.25 mm.

The Stacked HP1 image sensor has two row-select TSV blocks on the right and left sides of the die, adjacent to the bond pads, and one column-out TSV block located at the bottom of the Die, as shown in Figure 1 (red arrows). The observed Die Marking (Figure 2) indicates this is an S5KHP1SP sensor.

Tetra2 Pixel Chroma

TechInsights has confirmed that the HP1 utilizes a Tetra2 Pixel Chroma (or a 4 x 4 pixel group per color filter), which represents Samsung’s first implementation of such a large color filter array (CFA) mosaic. Accordingly, the HP1 CFA pitch is 2.56 µm.

The 4×4 Chroma, shown in Figure 3, is consistent with a 4×4 pixel binning which is reportedly used for imaging under low light conditions, at a resolution of 12.5 MP. It is also reported that the HP1 supports a 2×2 de-mosaic output of the 4×4 CFA, which is processed in the stacked ISP chip, for intermediate lighting conditions, with an effective resolution of 50 MP.

Auto Focus

For auto focus, the HP1 uses a Double Super PD Phase Detection Autofocus (PDAF) implemented through two side-by-side 2×1 on-chip-lens (OCL) strategy, as shown in Figure 3. This facilitates a 2×2 on-chip lens (OCL) omni-directional PDAF approach and is the same approach observed on its predecessor, the Samsung 50 MP JN1.
