The world of image sensors, a crucial component in digital cameras and numerous other devices, is a high-stakes game where research and development costs can be prohibitively expensive. As a result, many camera brands opt to outsource their sensor production to companies like Sony Semiconductor, which has established itself as a leader in the field. However, Canon stands out as a notable exception, with its executives remaining committed to developing image sensors in-house for use in their own cameras.
In an interview with PetaPixel at the CP+ event in late February, Go Tokura, Executive Vice President of Canon’s Imaging Group, reaffirmed the company’s dedication to this approach. “Yes, developing image sensors is a significant investment, but we’re determined to continue down this path to create sensors for our own cameras,” he stated. Tokura emphasized the importance of this strategy in differentiating Canon’s products, citing the advanced autofocus features on their flagship EOS R1 model as a prime example.
The conversation also touched on Global Shutter technology, which is currently exclusive to Sony in the consumer camera market. Although Canon has developed sensors utilizing this technology for industrial and scientific applications, the question remains whether they will integrate it into their digital cameras. Tokura acknowledged the significance of Global Shutter but noted the challenges associated with it, such as the trade-off with dynamic range. “We’re aware of these issues and will continue to work on improving our sensors to address them,” he said.
This response suggests that Canon may not be ready to compromise on the dynamic range and other performance aspects, which could be a contributing factor to their decision not to implement Global Shutter in their EOS R1 flagship model. The technology, as seen in Sony’s a9 III, comes with a price – reduced dynamic range and low-light performance. Canon’s cautious approach might indicate that the trade-offs are not yet worth it.
Interestingly, despite not equipping their EOS R1 with a high-megapixel sensor, Canon’s team has been developing various high-resolution sensors, including a 410-megapixel full-frame CMOS sensor announced earlier this year.
Tokura mentioned that while they cannot disclose specific product plans, they aim to leverage the capabilities of their 410-megapixel sensor, exploring its potential for large-format printing and higher resolution applications. Additionally, they are working to improve frame rates, light sensitivity, and signal-to-noise ratio, which could lead to the development of new products incorporating these features.
Canon’s current highest resolution sensor for consumer cameras is 50 megapixels, leading some to wonder if there are issues with creating high-megapixel cameras. Tokura addressed this concern, stating, “If we just wanted to create a high-megapixel camera, we could do it. However, if we were to use a 100-megapixel sensor with current technology, we’d have to make significant compromises on other performance aspects, such as light sensitivity, burst mode, rolling shutter, data transfer speed, video recording duration, and heat dissipation, not to mention the increased cost of the camera itself.” He believes that this technology is still too early for practical implementation but expressed confidence that they will eventually overcome these challenges.
As the camera industry continues to evolve, it’s clear that Canon is committed to pushing the boundaries of image sensor development, even if it means taking a more cautious approach. With their sights set on improving existing technologies and exploring new applications, Canon is poised to remain a major player in the world of digital photography.
