II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 6,292,218 - "Electronic Camera for Initiating Capture of Still Images while Previewing Motion Images," Issued September 18, 2001
The Invention Explained
- Problem Addressed: The patent describes the technical challenge in early digital cameras of providing a live "preview" image on a built-in display without incurring the high cost and complexity of generating a broadcast-standard video signal (e.g., NTSC), which was the common approach in camcorders (’218 Patent, col. 1:14-22).
- The Patented Solution: The invention proposes a dual-mode camera architecture. A "motion preview mode" uses a "relatively more simple" and computationally less-intensive processing technique, implemented in dedicated hardware (an ASIC), to generate a low-resolution image stream sufficient for previewing on the camera's LCD (’218 Patent, col. 4:42-51). When the user decides to take a picture, a "still image mode" is initiated, which uses a "relatively more complex" and powerful processing technique, implemented in software on a general-purpose processor, to create a high-quality, high-resolution final image for storage (’218 Patent, col. 4:37-42; Abstract).
- Technical Importance: This separation of processing paths allowed manufacturers to include the critical "live view" feature in consumer digital cameras while managing the trade-offs between component cost, processing power, and final image quality that were dominant constraints of the era (’218 Patent, col. 2:40-54).
Key Claims at a Glance
- The complaint asserts independent claim 15 and dependent claims 23, 25, 26, and 27 (Compl. ¶8).
- Independent Claim 15 recites an electronic camera comprising, in part:
- An image sensor for capturing images with a first number of pixel values.
- A "motion processor" for generating a series of motion preview images having a second, lesser number of pixel values.
- A color display for presenting the motion images.
- A capture button to initiate still image capture while previewing.
- A "still processor" for generating a high-quality processed still image.
- A digital memory for storing the still image.
U.S. Patent No. 5,493,335 - "Single Sensor Color Camera with User Selectable Image Record Size," Issued February 20, 1996
The Invention Explained
- Problem Addressed: Early digital cameras were constrained by limited and slow memory, creating a need for users to choose between storing a few high-resolution images or many low-resolution images. The patent notes that prior art methods of reducing resolution often occurred late in the processing chain, which could introduce noise and limit the speed of capturing a "burst" of images (’335 Patent, col. 1:20-42, col. 1:56-col. 2:2).
- The Patented Solution: The invention discloses a camera with a "resolution mode switch" that allows a user to select an image record size. This switch controls a timing controller that alters how image data is read from the sensor. For a reduced resolution mode, the controller effects a "subsampling" of the raw, "baseband" color image pixels directly from the sensor, storing only a fraction of the available pixels (’335 Patent, Abstract; col. 2:36-46). This subsampling occurs before significant processing, which is more efficient and avoids processing-related artifacts.
- Technical Importance: This approach provided an efficient mechanism for managing scarce memory resources, enabling features like a "burst mode" where multiple low-resolution images could be captured in rapid succession into a buffer, bypassing the bottleneck of writing to slow permanent storage (’335 Patent, col. 2:46-56).
Key Claims at a Glance
- The complaint asserts independent claim 1 (Compl. ¶14).
- Independent Claim 1 recites an electronic camera comprising, in part:
- An image sensor generating a baseband signal from a color filter array.
- A buffer memory and a separate output memory.
- A "resolution mode switch" for selecting between a "full resolution mode" and at least one "reduced resolution mode."
- A "controller" that responds to the switch by "effecting a subsampling of the color image pixels for the reduced resolution mode."
- Means for storing the selected color image pixels in the output memory.
III. The Accused Instrumentality
Product Identification
The complaint identifies the iPhone 3GS mobile device as the accused instrumentality (Compl. ¶8, ¶14).
Functionality and Market Context
The complaint does not provide specific details about the camera functionality of the accused product. The infringement counts are premised on the standard operation of the iPhone 3GS camera, which involves displaying a real-time video preview on its screen that allows a user to compose a shot, and capturing a higher-resolution digital still photograph for storage when the user actuates a screen-based button (Compl. ¶8, ¶14).
IV. Analysis of Infringement Allegations
The complaint provides only general allegations of infringement without specific factual mapping. The following charts are based on the asserted claims and the publicly understood functionality of the accused product. No probative visual evidence provided in complaint.
’218 Patent Infringement Allegations
| Claim Element (from Independent Claim 15) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| (b) a motion processor for generating... a second number of color pixel values... representative of a series of motion images to be previewed, the second number of color pixel values being less than the first number... | The iPhone 3GS uses its image processing circuitry to generate a continuously updated, lower-resolution video stream from its high-resolution sensor to serve as the live preview on the device's display. | ¶8 | col. 4:42-51 |
| (d) a capture button for initiating capture of a still image while previewing the motion images... | The iPhone 3GS user interface includes a software button that, when pressed by a user viewing the live preview, initiates the capture of a full-resolution still photograph. | ¶8 | col. 3:26-34 |
| (e) a still processor for generating a third number of color pixel values... representative of a processed captured still image... | The iPhone 3GS uses its image processing circuitry and software to perform complex operations (e.g., demosaicing, color correction, compression) on the full-resolution data from the sensor to create the final stored JPEG image. | ¶8 | col. 4:37-42 |
’335 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a resolution mode switch for selecting a pixel resolution of the image by specifying an order in which the color image pixels are selected... said order including a full resolution mode... and at least one reduced resolution mode... | The iPhone 3GS camera application or operating system provides a user-selectable setting or mode (e.g., photo vs. video mode) that changes the resolution of the image being captured and stored. | ¶14 | col. 4:59-64 |

- Identified Points of Contention:
- Scope Questions: A primary issue for the ’218 patent may be whether the terms "motion processor" and "still processor" require distinct hardware components. The patent specification contrasts a hardware-based ASIC with a software-based CPU (’218 Patent, col. 4:42-49). The infringement analysis will question if the highly integrated System-on-a-Chip (SoC) architecture in the iPhone 3GS, which may perform both functions on unified hardware, satisfies this two-processor limitation.
- Technical Questions: For the ’335 patent, a key technical question is when and how the accused device performs resolution reduction. The claim requires "subsampling of the color image pixels" from a "baseband image signal" (’335 Patent, cl. 1). The case may turn on evidence showing whether the iPhone 3GS performs subsampling on raw sensor data before other processing, as the patent teaches, or whether it uses a different method, such as scaling a fully-formed image later in the processing pipeline.
V. Key Claim Terms for Construction
The Term: "motion processor" / "still processor" (’218 Patent, cl. 15)
- Context and Importance: These terms define the core two-path architecture of the invention. The viability of the infringement claim depends on whether Apple's SoC can be shown to have two functionally separate "processors" as claimed, even if the hardware is physically integrated. Practitioners may focus on this term because modern processors often perform multiple functions, and the dispute will center on whether this functional distinction is sufficient to meet the claim language.
- Intrinsic Evidence for a Broader Interpretation: The claims use functional language (e.g., "a motion processor for generating..."), which may support an interpretation where different software routines or distinct processing blocks within a single SoC could be considered separate "processors" for the purpose of the claim.
- Intrinsic Evidence for a Narrower Interpretation: The specification consistently distinguishes between a "hardwired digital signal processing circuit (part of the ASIC)" for the preview mode and a "software driven digital processing system" for the still mode, describing them as distinct entities (’218 Patent, col. 4:42-49). This may support a narrower construction requiring structural or significant architectural separation, not just different software threads on the same core.
The Term: "resolution mode switch" (’335 Patent, cl. 1)
- Context and Importance: This term is the input mechanism that triggers the claimed subsampling function. Its construction will determine whether a software-based user interface element can be considered a "switch."
- Intrinsic Evidence for a Broader Interpretation: The term "switch" is not explicitly defined in the patent, which could support a broad, functional definition encompassing any user control that selects between different operational modes.
- Intrinsic Evidence for a Narrower Interpretation: The preferred embodiment describes and depicts a physical hardware switch (element 88b) as part of the "control and display section" (’335 Patent, Fig. 1; col. 4:59-64). A defendant may argue that this context limits the term to a physical, rather than a purely graphical, control.
VI. Other Allegations
- Indirect Infringement: The complaint alleges both induced and contributory infringement. Inducement is based on allegations that Apple encourages infringement with knowledge, such as by "creating and/or disseminating user manuals" that instruct on the use of the infringing features (Compl. ¶9, ¶15). Contributory infringement is based on allegations that Apple provides components "especially made or specially adapted for use in infringement" that are not staple articles of commerce (Compl. ¶10, ¶16).
- Willful Infringement: Plaintiff alleges that Apple had "actual knowledge of the... patent[s] in advance of the filing of this complaint" and requests enhanced damages for willful infringement (Compl. ¶11, ¶17; p. 5, ¶4).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of architectural equivalence: Can the distinct "motion processor" and "still processor" of the '218 patent, which the specification describes as a hardware ASIC and a software-driven CPU, be read onto the functions of a modern, highly integrated System-on-a-Chip (SoC) in the accused device?
- A second central question will be one of technical mechanism: Does the accused device's resolution-scaling feature, as required by the '335 patent, operate by "subsampling" raw "baseband" pixel data directly from the sensor, or does it perform scaling on an already-processed image, potentially placing it outside the claim's scope?
- A third key question will involve claim construction: Can the term "switch," described in the '335 patent's embodiment as a physical button, be construed broadly enough to cover a software-based control in a graphical user interface?
